example code not working #66

nutmix · 2023-04-06T16:29:44Z

I have tried to get the supplied example code to work, but it only produces a plain list of names, there is no indentation or option to open/close nodes. Whats going wrong?

The output is this:

Fruit
Apple
Banana
Cherry

But it should be this:

 >Fruit
   >Apple
   >Banana
      >Cherry

The code is this:

(Note, i found the js at unpkg, but I could not find the css, so I downloaded the css from the "dist" dir)

<!DOCTYPE html>

  <meta charset="UTF-8">

    // Define the JSON data to display
const data = {
    id: 'fruit',
    name: 'Fruit',
    children: [{
        id: 'apple',
        name: 'Apple'
    }, {
        id: 'banana',
        name: 'Banana',
        children: [{
            id: 'cherry',
            name: 'Cherry',
            loadOnDemand: true
        }]
    }]
};

      const tree = new InfiniteTree({
    el: document.querySelector('#tree'),

        return false;
    },
    loadNodes: function(parentNode, next) {
        // Loading...
        const nodes = [];
        nodes.length = 1000;
        for (let i = 0; i < nodes.length; ++i) {
            nodes[i] = {

                loadOnDemand: true
            };

I also tried to get chatgpt to create a working version of infinite-tree. It came up with:

    const tree = new InfiniteTree("#tree", {
      data: data,
      loadChildren: function(node, done) {
        done(node.children || []);
      }
    });

Which doesnt show anything at all - just blank.
