用Ajax回调，你这样怎么取出来。

Ext.onReady(function () {
    new Ext.Button({
        renderTo: "div1",
        text: "后台Ajax提交",
        handler: function () {
            Ext.Ajax.request({
                url: 'Ajax_Func1',
                headers: {
                    'userHeader': 'userMsg'
                },
                params: { a: 10, b: 20 },
                method: 'GET',
                success: function (response, options) {
                    Ext.MessageBox.alert('成功', '从服务端获取结果: ' + response.responseText);
                },
                failure: function (response, options) {
                    Ext.MessageBox.alert('失败', '请求超时或网络故障,错误编号：' + response.status);
                }
            });
        },
        id: "bt1"
    });

});
