ext创建树的脚本

function ShowWindow() {
    //调用button的on方法设置监听函数
    var btn = new Ext.Button({
        text: "创建一个窗口"
    });
    btn.on("click", ShowMinWindow);

    var win = new Ext.Window({
        width: 500,
        height: 300,
        title: "My Ext Window",
        maximizable: true,
        minimizable: true,
        maximize: function () { win.hide(); },
        buttons: [{ text: "创建一个带数的窗口",
            listeners: {
                click: function () {
                    var tree = new Ext.tree.TreePanel({

                        width: 500,
                        height: 300,
                        title: "树的测试",
                        root: new Ext.tree.AsyncTreeNode({
                            text: "子节点1",
                            children: [{ text: "子节点11", children: [{ text: "子节点111", leaf: true}] }, { text: "子节点2", leaf: true}]
                        })
                    });

                    var w1 = new Ext.Window({
                        width: 300,
                        height: 400,
                        title: "树",
                        items: [tree]
                    });
                    //w1.add(tree);
                    w1.show();
                }
            }
        }, btn]
    });
    win.show();
}

function ShowMinWindow() {
    var win = new Ext.Window({
        width:200,
        height: 100,
        title:"弹出窗口"
    });
    win.show();
}

Ext.onReady(ShowWindow);
