wdTree 轻量级的 jQuery 目录树插件

Question

wdTree 是一个轻量级的 jQuery 目录树插件，支持多级目录选择，目录和文件复选框选项，获取复选框的值，支持多个配置参数自定义，多个回调函数配置，还可以从其他页面 AJAX Loading 数据加载。

使用方法

要使用这个插件，需要一个 HTML 的元素，比如下面的代码：

<div id="tree"></div>

然后调用插件

var o = {
    showcheck: true
    //onnodeclick:function(item){alert(item.text);},        
};
o.data = treedata;                  
$("#tree").treeview(o);

获取Checkbox选择中的元素

$("#showchecked").click(function(e){
    var s=$("#tree").getCheckedNodes();
    if(s !=null)
    alert(s.join(","));
    else
    alert("NULL");
});

获取当前选中的元素

$("#showcurrent").click(function(e){
    var s=$("#tree").getCurrentNode();
    if(s !=null)
        alert(s.text);
    else
        alert("Current node is nothing");
});

配置参数

data配置支持一下的配置参数

data:[{
    id:"node1", //node id
    text:"node 1", //node text for display.
    value:"1", //node value
    showcheck:false, //whether to show checkbox
    checkstate:0, //Checkbox checking state. 0 for unchecked, 1 for partial checked, 2 for checked.
    hasChildren:true, //If hasChildren and complete set to true, and ChildNodes is empty, tree will request server to get sub node.
    isexpand:false, //Expand or collapse.

    ChildNodes:[] // child nodes
}]
