捕获标签单击事件

Question

我正在使用jqxWidgets树菜单，但似乎找不到一种方法来捕获jquery中标签的单击事件。有没有办法在jquery中捕获这个标签进行处理？我已经包括了相关的代码片段，并感谢您的专家建议。非常感谢

 <script type="text/javascript">
  $(document).ready(function () {
    var source = [
    { label: "Weekly Reports", expanded: false, items: [
        { label: "Intake" },
        { label: "Retrieval", selected: false },
        { label: "Returns", selected: false }
    ]
    },
    /*{ label: "Item 2" },
    { label: "Item 3" },*/
    { label: "Monthly Reports", items: [
        { label: "Item 4.1" },
        { label: "Item 4.2" }
    ]
    },
    /*{ label: "Item 5" },
    { label: "Item 6" },
    { label: "Item 7" }*/
    { label: "Movement Reports", items: [
        { label: "Item 4.1" },
        { label: "Item 4.2" }
    ]
    },
     { label: "Destruction Reports", items: [
        { label: "Item 4.1" },
        { label: "Item 4.2" }
    ]
    },
];
  var theme = "";
  // Create jqxTree
  $("#jqxTree").jqxTree({ source:source, theme: theme });

  // Create jqxExpander
  $("#jqxExpander").jqxExpander({  showArrow: false, toggleMode: "none", width: "262px", height: "auto", theme: theme });
  });
</script>

jqxTree具有针对select事件的内置回调。您可以捕获此事件并检索单击的标签，如下所示：

$('#jqxTree').on('select',function (event){
    var args = event.args;
    var item = $('#jqxTree').jqxTree('getItem', args.element);
    var label = item.label; 
});
