[SOLVED] Checking whether pywebview is available or otherwise

[sjehuda]

Is there a way to verify whether pywebview API is available or not?

The I have attempted several types of checks and all have failed

    // Check if pywebview API and regulator function are available
    const isPyWebviewAvailable = () => {
        return window.pywebview?.api?.regulator instanceof Function;
    };

and

if (window.pywebview && window.pywebview.api && window.pywebview.api.regulator) {

Related to #1459

There is pywebviewready DOM event that is fired right after API is ready

Thank you!

The following ECMAScript code works for the Python code of #1459

document.addEventListener('DOMContentLoaded', () => {
    window.addEventListener('pywebviewready', () => {
        // Attach event listeners to all anchor elements
        document.querySelectorAll('a').forEach(element => {
            element.addEventListener('click', regulator);
        });
    });
});


// This function will be called when an anchor is clicked
function regulator(event) {
    event.preventDefault(); // Prevent the default link behavior
    const url = this.href; // Get the URL from the clicked link
    
    // Call the exposed Python function
    window.pywebview.api.regulator(url)
        .catch(error => {
            console.error("Error calling regulator:", error);
        });
}
