store里面的方法
Ext.define('AM.store.TraderNews', {
extend: 'Ext.data.Store',
model: 'AM.model.TraderNew',
autoLoad: false,
pageSize: 1500,
//---------- add by zhangxin 2012.1.5 整体排序 start----------
remoteSort: true,
//---------- add by zhangxin 2012.1.5 整体排序 end----------
proxy: {
type: 'ajax',
api: {
read: '/Trader/JsonIndexNew'//调用TraderController里面的JsonIndexNew方法
},
reader: {
type: 'json',
root: 'data'
}
}
});
进入.net的后台方 url: '/Trader/JsonIndexNew',
public JsonResult JsonIndexNew()
{
var tradersList = dbContent.FindAll();
string searchstring = "";
if (Request["query"] != null && Request["query"].Length > 0)
{
searchstring = Request["query"];
}
var companay = from it in tradersList select new { it.traderid, it.companay };
companay = companay.Where(it => it.companay.Contains(searchstring));
return Json(new { success = true, data = companay}, JsonRequestBehavior.AllowGet);
}
实现效果
