JavaScript运行时错误， this.el.dom为空或错误

Question

Ext.onReady(function() {
var window = new Ext.Window({//xxx});
var store = new Ext.data.Store({
                    proxy: new Ext.data.HttpProxy({ url: 'xx' }),
                    reader: new Ext.data.JsonReader({
                        totalProperty: xx,
                        root: 'xx',
                        id: 'xx',
                        fields: [xx]
                    }),
                    sortInfo: { xx },
                    remoteSort: true
                });
           store.on("beforeload", function() {
                    var values = window.items.items[0].form.getValues();
                    store.setBaseParam('xx', values.xx);
                    store.setBaseParam('xx', values.xx);
                    store.setBaseParam('xx', values.xx);
                }, store);
        var grid = new Ext.grid.GridPanel({
             ///....
                  })
       var viewport = new Ext.Viewport({
                    layout: 'border',
                    renderTo: Ext.getBody(),
                    items: [grid]
                });
                // 加载列表'
                storeLog.load({ params: { start: 0, limit: xx} });
 });
代码大概就是这样，应该是在加载数据时出错，但是不知道具体是哪的错误，请指点！

Answer 1

测了，是在store.load（）时中断的，搞不明白啊，这时候怎么会出这个问题

Answer 2

Ext.onReady(function() {
//var window = new Ext.Window({//xxx});
var store = new Ext.data.Store({
                    proxy: new Ext.data.HttpProxy({ url: 'xx' }),
                    reader: new Ext.data.JsonReader({
                        totalProperty: xx,
                        root: 'xx',
                        id: 'xx',
                        fields: [xx]
                    }),
                    sortInfo: { xx },
                    remoteSort: true
                });
           store.on("beforeload", function() {
                    var values = window.items.items[0].form.getValues();//这个values是否是对
                    //window.items.items[0].form是否是一个对象
                    store.setBaseParam('xx', values.xx);
                    store.setBaseParam('xx', values.xx);
                    store.setBaseParam('xx', values.xx);
                }, store);
        var grid = new Ext.grid.GridPanel({
             ///....
                  })
       var viewport = new Ext.Viewport({
                    layout: 'border',
                    renderTo: Ext.getBody(),
                    items: [grid]
                });
                // 加载列表'
               // storeLog.load({ params: { start: 0, limit: xx} });
               store.load({ params: { start: 0, limit: xx} });
 });

Answer 3

store.on("beforeload", function() {
                    var values = window.items.items[0].form.getValues();
                    store.setBaseParam('xx', values.xx);
                    store.setBaseParam('xx', values.xx);
                    store.setBaseParam('xx', values.xx);
                }, store);
这段代码很可疑。 把方法的实现清空。 看报错不。 把错误缩小到这个方法

Answer 4

store.setBaseParam//看看这个方法有没有问题
values.xx//拿到值了没
var values = window.items.items[0].form.getValues();有没有值

Answer 5

var values = window.items.items[0].form.getValues();//这个values是否是对这里为什么要这样写？
var form = Ext.getCmp("queryForm").getForm(); 
store.baseParams = form.getValues(); 这样试下？
