How to Create a jQuery uiTree Clone?

Estimated read time 3 min read

To create a jQuery uiTree clone, you can follow these steps:

  1. Include the jQuery library and the uiTree plugin in your HTML file. Here’s an example:
<script src="https://code.jquery.com/jquery-3.3.1.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jstree/3.2.1/jstree.min.js"></script>
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/jstree/3.2.1/themes/default/style.min.css" />
  1. Create an HTML element that will hold the uiTree. Here’s an example:
<div id="tree"></div>
  1. Add some JavaScript code that will initialize the uiTree and allow dragging and dropping nodes. Here’s an example:
$('#tree').jstree({
  "core": {
    "check_callback": true
  },
  "plugins": ["dnd"]
});

This code will initialize the uiTree with the “core” and “dnd” plugins, which enable drag-and-drop functionality and allow the tree structure to be modified.

  1. Add some CSS code to style the uiTree elements. Here’s an example:
#tree li.jstree-draggable {
  background-color: #f1f1f1;
  border: 1px solid #ccc;
}

#tree li.jstree-dragging {
  opacity: 0.5;
}

This code will style the draggable and dragging elements of the uiTree.

  1. Add some JavaScript code that will create a clone of the uiTree when the user starts dragging a node. Here’s an example:
var clonedNode = null;

$('#tree').on('mousedown.jstree', '.jstree-anchor', function(event) {
  clonedNode = $(event.target).closest('.jstree-node').clone();
  clonedNode.addClass('cloned-node');
  clonedNode.css('position', 'absolute');
  clonedNode.css('z-index', '1000');
  clonedNode.appendTo('body');
});

$(document).on('mousemove', function(event) {
  if (clonedNode) {
    clonedNode.offset({ left: event.pageX - 10, top: event.pageY - 10 });
  }
});

$(document).on('mouseup', function(event) {
  if (clonedNode) {
    clonedNode.remove();
    clonedNode = null;
  }
});

This code will listen for the mousedown event on the uiTree nodes, and create a clone of the node that was clicked. The clone will be styled with a “cloned-node” class, positioned absolutely on the page, and appended to the body element. The code will also listen for the mousemove event on the document, and update the position of the clone to follow the mouse. Finally, it will listen for the mouseup event on the document, and remove the clone from the page.

That’s it! Now, the user can drag and drop nodes within the uiTree, and also create a clone of a node by clicking and dragging it. You can customize the uiTree and clone behavior by modifying the JavaScript and CSS code.
