  • Drag and drop problem #30235


    Hi everyone,

    I’m using a jqTree in JSON to organise training periods.

    I have potentially 4 levels of depth in my tree, and i’m using drag&drop to organize it.

    Everything works fine, but i’m unable to find the NEW POSITION of the item dragged & dropped.

    allowDrag: true,
    allowDrop: true,
    dragStart: function (item) {
    dragEnd: function (item) {

    the item in dragEnd: function is at his dragged state (for every prop).

    I tried to list props of the item to see if any was containing info on where the item is dropped, no match.

    How can i know where the item is dropped (to then launch my php script saving changes)

    Thanks for reading.
    Hope I’ll get some help on this, pulling my hair since 3 hours ><

    I also want to be able to prevent drag from a different level, is there any way to do that ?

    Hello ashensugar,

    The dropItem argument of the dragEnd callback function contains information about the drop target.

    And here is an example that shows how to disable dragging of items with level other than 0 and alert the dropItem’s label:

    <!DOCTYPE html>
    <html lang="en">
    <title id='Description'>jQuery Tree Sample</title>
    <link rel="stylesheet" href="../../jqwidgets/styles/jqx.base.css" type="text/css" />
    <script type="text/javascript" src="../../scripts/jquery-1.10.2.min.js"></script>
    <script type="text/javascript" src="../../jqwidgets/jqxcore.js"></script>
    <script type="text/javascript" src="../../jqwidgets/jqxbuttons.js"></script>
    <script type="text/javascript" src="../../jqwidgets/jqxscrollbar.js"></script>
    <script type="text/javascript" src="../../jqwidgets/jqxpanel.js"></script>
    <script type="text/javascript" src="../../jqwidgets/jqxtree.js"></script>
    <script type="text/javascript" src="../../jqwidgets/jqxdragdrop.js"></script>
    <script type="text/javascript">
    $(document).ready(function () {
    // Create jqxTree
    $('#jqxTree').jqxTree({ height: '300px', width: '300px', allowDrag: true, allowDrop: true,
    dragStart: function (item) {
    if (item.level > 0) {
    return false;
    dragEnd: function (dragItem, dropItem, args, dropPosition, tree) {
    alert("Dropped over " + dropItem.label + ".");
    <body class='default'>
    <div id='jqxTree'>
    <li item-selected='true'>Home</li>
    <li item-expanded='true'>Solutions
    <li>Financial services</li>
    <li>Consumer photo and video</li>
    <li>Rich Internet applications</li>
    <li>Technical communication</li>
    <li>Training and eLearning</li>
    <li>Web conferencing</li>
    <li>All industries and solutions</li>
