试过Grid自带的load和分页功能，没有成功，干脆就自己写了......
主要是查询条件比较复杂......
希望哪位大神能有更好的意见。

查询按钮被点击时
1 onClickSearchButton : function(btn) {//点击“查询”按钮执行
2 // 获取查询条件
3 var operatorSearchForm = btn.up(‘form‘);
4 var obj = operatorSearchForm.getViewModel().getData();
5 //查询条件obj转码
6 var tools = Ext.create(‘MyApp.Tools‘);
7 var httpParams = tools.objectToHttpOgnlParams(obj,null,3);
8 operatorSearchForm.submit({//获取查询结果总条数
9 url : ‘operatorCount.action‘,
10 params : httpParams,
11 method : ‘post‘,
12 waitMsg:‘稍安勿躁...‘,
13 success : function(basicForm, action) {
14 //每页条数
15 var limit = 10;
16 //总页数（查询总记录数除以每页条数，向上取整）
17 var total = Math.ceil(action.result.total/limit);
18 // 找到对应显示的表格
19 var OperatorGridInSearchForm = Ext.ComponentQuery.query(‘#OperatorGridInSearchForm‘)[0];
20 //找到表格下的分页条
21 var toolbar = OperatorGridInSearchForm.down(‘toolbar‘);
22 //执行查询
23 toolbar.doSearch(limit,total,obj);
24 },
25 failure : function() {
26 Ext.Msg.alert(‘悲剧‘, ‘查询操作失败，请重试‘);
27 }
28 });
