Installation

You'll first need to install ESLint:

$ npm i eslint --save-dev

Next, install eslint-plugin-jquery-compat:

$ npm install @frogeducation/eslint-plugin-jquery-compat --save-dev

Note: If you installed ESLint globally (using the -g flag) then you must also install eslint-plugin-jquery-compat globally.

Usage

Add jquery-compat to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:

{
    "plugins": [
        "@frogeducation/jquery-compat"
    ]
}

Then configure the rules you want to use under the rules section.

{
    "rules": {
        "@frogeducation/jquery-compat/no-parse-json": 2
    }
}

Alternatively, extend the recommended config:

{
  "extends": [
    // enables all recommended rules
    "plugin:@frogeducation/jquery-compat/recommended",
  ]
}

There are also two tags v1.9 and v3.0 for the upgrade checkpoints, and special tags for every version that enable only the fixes that can be applied at every three-digit version up to 3.4.1 (i.e. while preparing for an upgrade from 1.7 to 1.9, anything added in 1.8 is not yet fixable as you have not yet upgraded the jQuery version)

{
  "extends": [
    // enables only the rules required to upgrade 1.0 to 1.9
    "plugin:@frogeducation/jquery-compat/v1.9",
    // enables only the rules that are fixable from v1.7 upwards
    "plugin:@frogeducation/jquery-compat/fixable-from-v1.7.0"
  ]
}

and finally, rules that only apply to JMVC users:

{
  "extends": [
    // enables only the rules required for JMVC users
    "plugin:@frogeducation/jquery-compat/jmvc"
  ]
}

v3.0

@frogeducation/jquery-compat/no-capitalised-html-data-attributes

JQMIGRATE: jQuery.data() always sets/gets camelCased names

Data attribute capitalisation is now standardised in jQuery; only word-boundaries in kebab-cased HTML data attributes are respected.

Keeping HTML data attributes lowercased avoids confusion.

Examples of incorrect code for this rule:

$('<div data-helloWorld="no" />').data('helloWorld') // --> undefined
$('<div data-helloWorld="no" />').data('helloworld') // --> "no"

Examples of correct code for this rule:

$('<div data-hello-world="yes" />')

v1.9

@frogeducation/jquery-compat/attr-select

JQMIGRATE: `jQuery.fn.attr('selected')` might use property instead of attribute

Cause: Prior to jQuery 1.9, $().attr("checked") etc. would sometimes use the checked|selected property instead of the attribute when interacting with non-XML elements, despite the fact that browsers and the HTML specifications allow the properties (current state) to differ from the attributes (initial/default state). This was a holdover from earlier versions of jQuery that did not offer $().prop.

Solution: Boolean properties should generally not be passed to $().attr at all; replace with $().prop unless you truly intend to update the underlying HTML attribute.

Examples of incorrect code for this rule:

if ($foo.attr("selected")) { /* ... */ }

if ($foo.attr("checked")) { /* ... */ }

if ($foo.attr("disabled")) { /* ... */ }

Examples of correct code for this rule:

if ($foo.prop("selected")) { /* ... */ }

if ($foo.prop("checked")) { /* ... */ }

if ($foo.prop("disabled")) { /* ... */ }

@frogeducation/jquery-compat/deferred-use-state

JQMIGRATE: `deferred.isResolved()` / `deferred.isRejected()` is deprecated

deferred.isRejected() and deferred.isResolved() were removed in jQuery 1.8; use deferred.state() === 'rejected' and deferred.state() === 'resolved' instead (deferred.state() may also return 'pending').

Examples of incorrect code for this rule:

var myDeferred = $.Deferred()

if (myDeferred.isRejected()) {
  /* ...snip... */
} else (myDeferred.isResolved()) {
  /* ...snip... */
}

Examples of correct code for this rule:

var myDeferred = $.Deferred()

} else (myDeferred.state() === 'resolved') {
  /* ...snip... */

@frogeducation/jquery-compat/html-string-must-start-with-tag

JQMIGRATE: `$(html)` HTML strings must start with '<' character

Cause: In jQuery 1.9, HTML strings passed to $() must start with a tag; in other words the first character of the string must be a < character. There cannot be any preceding characters, including whitespace. This is done to reduce the chances of inadvertent execution of scripts that might be present in HTML that is obtained from the URL, AJAX, or other sources. Use of simple literal HTML strings like $("<div />") or $("<p>hello</p>") are unaffected since they should not have leading spaces or text.

Solution: Use the $.parseHTML() method to parse arbitrary HTML, especially HTML from external sources. To obtain a jQuery object that has the parsed HTML without running scripts, use $($.parseHTML("string")). To run scripts in the HTML as well, use $($.parseHTML("string", document, true)) instead. We do not recommend running $.trim() on the string to circumvent this check.

Examples of incorrect code for this rule:

$("hello <strong>world</strong>")

Examples of correct code for this rule:

$($.parseHTML("hello <strong>world</strong>"))

$("<span>hello <strong>world</strong></span>")

@frogeducation/jquery-compat/jmvc/no-null-model-calls

$.param no longer encodes null/undefined

Cause: jQuery.param() (used to build query string parameters in api calls from models) no longer encodes null or undefined as strings; in stead it encodes them as empty strings.

Solution: Rewrite any code that passes null or undefined to model calls to pass these as strings, or omit them, as appropriate.

Examples of incorrect code for this rule:

Foo.Models.Bar.baz({ foo: null, bar: undefined, baz: 42 })

Examples of correct code for this rule:

Foo.Models.Bar.baz({ foo: "null", bar: "undefined", baz: 42 })

Foo.Models.Bar.baz({ baz: 42 })

@frogeducation/jquery-compat/no-attr-value

JQMIGRATE: `jQuery.fn.attr('value')` no longer gets properties

Prior to jQuery 1.9, $().attr("value") retrieved the value property instead of the value attribute (which generally reflects the value that was read from HTML markup). $().attr( "value", val ) set the value property instead of the value attribute. This caused inconsistent behavior with selectors referencing the value attribute.

Use $().val() (for form controls) or $().prop("value") (for other elements) to get the current value, and try to explicitly limit the use of [value=…] in selectors to input and/or option elements wherever possible. Use $().val( val ) (for form controls) or $().prop( "value", val ) (for other elements) to set the current value.

Examples of incorrect code for this rule:

var value = $('input.foo').attr('value')
$('input.foo').attr('value', 'newValue')

Examples of correct code for this rule:

var value = $('input.foo').val()
$('input.foo').val('newValue')

var value2 = $('div.bar').prop('value')
$('div.bar').prop('value', 'newValue')

@frogeducation/jquery-compat/no-attrfn

JQMIGRATE: `jQuery.attrFn` is deprecated

Cause: Prior to jQuery 1.8, the undocumented jQuery.attrFn object provided a list of properties supported by the $(html, props) method. It is no longer required as of jQuery 1.8, but some developers "discovered" it by reading the source and began to use it. Their code still expects jQuery.attrFn to be present, attempts to assign values to it, and will throw errors if it is not present.

Solution: Ensure that you are using the latest version of jQuery UI (1.8.21 or later) and jQuery Mobile (1.2.1 or later); they no longer use jQuery.attrFn. Examine any third-party plugins for the string attrFn and report its use to the plugin authors (not to jQuery team).

Examples of incorrect code for this rule:

$.attrFn.foo = "bar"

@frogeducation/jquery-compat/no-box-model

JQMIGRATE: `jQuery.boxModel` / `jQuery.support.boxModel` is deprecated

These two deprecated properties are false when the page is using Quirks mode, and true when the page is in standards mode. Quirks mode was never supported in jQuery so these properties were removed.

Do not use jQuery in Quirks mode, it has never been supported.

Examples of incorrect code for this rule:

if ($.boxModel) { /* ...snip... */ }

if ($.support.boxModel) { /* ...snip... */ }

if (jQuery.boxModel) { /* ...snip... */ }

if (jQuery.support.boxModel) { /* ...snip... */ }

@frogeducation/jquery-compat/no-browser

JQMIGRATE: jQuery.browser is deprecated

jQuery.browser was deprecated in version 1.3, and finally removed in 1.9. Browser sniffing is notoriously unreliable as means of detecting whether to implement particular features.

Where possible, use feature detection to make code decisions rather than trying to detect a specific browser. The Modernizr library provides a wide variety of feature detections. As a last resort, you can directly look at the navigator.userAgent string to detect specific strings returned by the browser.

Examples of incorrect code for this rule:

if (!$.browser.msie) {
  console.log("supported!")
}

Examples of correct code for this rule:

if (window.someFeature) {
  console.log("supported!")
}

@frogeducation/jquery-compat/no-buildFragment

Cause: jQuery.buildFragment() and jQuery.clean() are undocumented internal methods. The signature of jQuery.buildFragment() was changed in jQuery 1.8 and 1.9, and jQuery.clean() was removed in 1.9. However, we are aware of some plugins or other code that might be using them.

Solution: Rewrite any code that makes use of these or any other undocumented methods. For example the jQuery.parseHTML() method, introduced in jQuery 1.8, can convert HTML to an array of DOM elements that you can append to a document fragment.

@frogeducation/jquery-compat/no-deferred-pipe

JQMIGRATE: deferred.pipe() is deprecated

The .pipe() method on a jQuery.Deferred object was deprecated as of jQuery 1.8, when the .then() method was changed to perform the same function.

In most cases it is sufficient to change all occurrences of .pipe() to .then(). Ensure that you aren't relying on context/state propagation (e.g., using this) or synchronous callback invocation, which were dropped from .then() for Promises/A+ interoperability as of jQuery 3.0.

Examples of incorrect code for this rule:

$.Deferred().pipe(fn)

Examples of correct code for this rule:

$.Deferred().then(fn)

@frogeducation/jquery-compat/no-deprecated-event-methods

JQMIGRATE: jQuery.fn.error() is deprecated

Many shortcut methods for attaching certain event handlers to elements were deprecated in jQuery 1.8/1.9, such as $.fn.load, $.fn.error, etc.

For most cases, simply changing the code to use $.fn.on('<event>', handler) instead will suffice, eg

Examples of incorrect code for this rule:

$('.foo').error(handler)
$('.foo').find('.bar').error(handler)
jQuery('.foo').error(handler)
$foo.error(handler)

$('.foo').load(handler)
$('.foo').unload(handler)

Examples of correct code for this rule:

$('.foo').on('error', handler)
$('.foo').find('.bar').on('error', handler)
jQuery('.foo').on('error', handler)
$foo.on('error', handler)

$('.foo').on('load', handler)
$('.foo').on('unload', handler)

@frogeducation/jquery-compat/no-document-on-ready

JQMIGRATE: 'ready' event is deprecated

Cause: Using one of jQuery's API methods to bind a "ready" event, e.g. $( document ).on( "ready", fn ), will cause the function to be called when the document is ready, but only if it is attached before the browser fires its own DOMContentLoaded event. That makes it unreliable for many uses, particularly ones where jQuery or its plugins are loaded asynchronously after page load.

Solution: Replace any use of $( document ).on( "ready", fn ) with $( document ).ready( fn ) or more simply, just $( fn ). These alternative methods work reliably even when the document is already loaded.

Examples of incorrect code for this rule:

$(document).on("ready", callback)

Examples of correct code for this rule:

$(document).ready(callback)

$(callback)

@frogeducation/jquery-compat/no-fn-data-events

JQMIGRATE: Use of jQuery.fn.data('events') is deprecated

Prior to 1.9, .data("events") could be used to retrieve jQuery's undocumented internal event data structure for an element if no other code had defined a data element with the name "events". This special case has been removed in 1.9.

There is no public interface to retrieve this internal data structure, and it remains undocumented. The only useful applications might be for debugging. The data is available via jQuery._data("events") but this is not a documented interface.

If this rule is flagging up code where an element is known to have custom data with the name "events", either use a different name to avoid confusion, or disable the rule for that particular piece of code:

$('.foo').data('events', 'my-custom-event-data')

// ...snip...

// eslint-disable-next-line jquery-compat/no-fn-data-events
var customEventData = $('.foo').data('events')

Examples of incorrect code for this rule:

$('.foo').data('events')

Examples of correct code for this rule:

$('.foo').data('custom-events')

@frogeducation/jquery-compat/no-fn-size

JQMIGRATE: jQuery.fn.size() is deprecated; use the .length property

The .size() method returns the number of elements in the current jQuery object, but duplicates the more-efficient .length property which provides the same functionality. As of jQuery 1.9 the .length property is the preferred way to retrieve this value.

@frogeducation/jquery-compat/no-global-trigger

JQMIGRATE: Global events are undocumented and deprecated

Cause: jQuery 1.9 does not support globally triggered events. The only documented global events were the AJAX events and they are now triggered only on document as discussed above. jQuery never provided a documented interface for outside code to trigger global events.

Solution: Change the program to avoid the use of global events. The jQuery Migrate plugin warns about this case but does not restore the previous behavior since it was undocumented.

Examples of incorrect code for this rule:

$.event.trigger(/*...*/)

@frogeducation/jquery-compat/no-hover-event

JQMIGRATE: 'hover' pseudo-event is deprecated, use 'mouseenter mouseleave'

Cause: Until jQuery 1.9, the string "hover" was allowed as an alias for the string "mouseenter mouseleave" when attaching an event handler. This unusual exception provided no real benefit and prevented the use of the name "hover" as a triggered event. Note: This is not related to the .hover() method, which has not been deprecated.

Solution: Replace use of the string "hover" with "mouseenter mouseleave" within any .on(), .bind(), .delegate(), or .live() event binding method.

Examples of incorrect code for this rule:

$foo.on("hover", callback)

Examples of correct code for this rule:

$foo.on("mouseenter mouseleave", inOutCallback)

$foo.on("mouseenter", inCallback)

$foo.hover(inCallback, outCallback)

$foo.hover(inOutCallback)

@frogeducation/jquery-compat/no-null-param

$.param no longer encodes null/undefined

Cause: jQuery.param() (used to build query string parameters in $.ajax) no longer encodes null or undefined as strings; in stead it encodes them as empty strings.

Solution: Rewrite any code that passes null or undefined to $.param or $.ajax to pass these as strings, or omit them, as appropriate.

Examples of incorrect code for this rule:

$.param({ foo: null, bar: undefined, baz: 42 })

Examples of correct code for this rule:

$.param({ foo: "null", bar: "undefined", baz: 42 })

$.param({ baz: 42 })

JSON.parse(input || 'null')

@frogeducation/jquery-compat/no-sub

JQMIGRATE: jQuery.sub() is deprecated

Cause: The jQuery.sub() method provided an imperfect way for a plugin to isolate itself from changes to the jQuery object. Due to its shortcomings, it was deprecated in version 1.8 and removed in 1.9.

Solution: Rewrite the code that depends on jQuery.sub(), use the minified production version of the jQuery Migrate plugin to provide the functionality, or extract the jQuery.sub() method from the plugin's source and use it in the application.

Examples of incorrect code for this rule:

$.sub(/*...*/)

@frogeducation/jquery-compat/no-swap

JQMIGRATE: jQuery.swap() is undocumented and deprecated

Cause: The jQuery.swap() method temporarily exchanges a set of CSS properties. It was never documented as part of jQuery's public API and should not be used because it can cause performance problems due to forced layout.

Solution: Rework the code to avoid calling jQuery.swap(), or explicitly set and restore the properties you need to change.

@frogeducation/jquery-compat/no-toggle-handler

JQMIGRATE: `jQuery.fn.toggle(handler, handler...)` is deprecated

There are two completely different meanings for the .toggle() method. The use of .toggle() to show or hide elements is not affected. The use of .toggle() as a specialized click handler was deprecated in 1.8 and removed in 1.9.

Rewrite the code that depends on $().toggle(), use the minified production version of the jQuery Migrate plugin to provide the functionality, or extract the $().toggle() method from the plugin's source and use it in the application.

Examples of incorrect code for this rule:

$('.foo').toggle(function() {
  console.log('.foo first click handler')
}, function() {
  console.log('.foo second click handler')
})

Examples of correct code for this rule:

$('.foo').toggle(1000, function() {
  console.log('.foo animation done')
})

• JQMIGRATE: jQuery.fn.toggle(handler, handler...) is deprecated

@frogeducation/jquery-compat/no-trailing-text-in-html-strings

JQMIGRATE: `$(html)` text after last tag is ignored

HTML strings passed to $() should begin and end with tags. Any text following the last tag is ignored. When upgrading to jQuery 1.9 and using $.parseHTML(), note that leading or trailing text is not ignored, and those text nodes will be part of the data returned.

Usually this warning is due to an error in the HTML string, where text is present when it should not be there. Remove the leading or trailing text before passing the string to $.parseHTML() if it should not be part of the collection. Alternatively you can use $($.parseHTML(html)).filter("*") to remove all top-level text nodes from the set and leave only elements.

Examples of incorrect code for this rule:

$('<h1>foo</h1>bar')

$('<h1>foo</h1>' + 'bar')

var text = '<h1>foo</h1>bar'
$(text)

var text = '<h1>foo</h1>' + 'bar'
$(text)

Examples of correct code for this rule:

$('<h1>foo</h1>')

$('<h1>foo</h1>' + '<h2>bar</h2>')

var text = '<h1>foo</h1>'
$(text)

@frogeducation/jquery-compat/quoted-hash-attribute-selectors

JQMIGRATE: Attribute selector with '#' must be quoted

Selectors such as a[href=#main] are not valid CSS syntax because the value contains special characters that are not quoted. Until jQuery 1.11.3/2.1.4 this was accepted, but the behavior is non-standard and was never documented. In later versions this selector throws an error. In some cases with complex selectors, Migrate may not attempt a repair. In those cases a fatal error will be logged on the console and you will need to fix the selector manually.

Put quotes around any attribute values that have special characters, e.g. a[href="#main"]. The warning message contains the selector that caused the problem, use that to find the selector in the source files.

Examples of incorrect code for this rule:

$('[href=#main]')

var selector = '[href=#main']

Examples of correct code for this rule:

$('[href="#main"]')

var selector = '[href="#main"]'
