Ext.data.Tree 数据对象与节点的点击事件

1. treeStore的C#类对象

public class ExtTreeNode
{
    string id;
    string text;
    string icon;
    string url;
    bool leaf;
    bool expanded;
    List<ExtTreeNode> children = new List<ExtTreeNode>();
}

2. Ext.tree

Ext.onReady(function () {
    //數據源
    var store = Ext.create('Ext.data.TreeStore', {
        proxy: {
            type: 'ajax',
            url: '../API/bbs/Default.ashx?API=menu'
        }
    });

    //树形配置
    treePanel = Ext.create('Ext.tree.Panel', {
        id: "TreeMenu",
        renderTo: 'basicTree',
        width: 300,
        store: store,
        minSize: 150,
        maxHeight:'100%;',
        autoScroll: true,
        rootVisible: false,
        singleExpand: false,
        collapsible: false,
        lines: true,
        split: true,
        listeners: {
            //鼠标右键
            itemcontextmenu: function (node, record, items, index, e) {
                var nodemenu = Ext.create('Ext.menu.Menu', {items: [{text: '權限管理',handler: function () {}},{text: '增加子節點',handler: function () { }}]});
                //取得鼠标点击坐标，展示菜单
                nodemenu.showAt(e.getXY());
            },
            //鼠标单击
            itemclick: function (node, record, index, e) {},
            //鼠标双击
            itemdblclick:function(){}
        }
    });
});
