这个类是自动完成对AspNet [System.Web.Services.WebMethod]方法的调用。该方法适合ie,chrome,firefox

/*Ext.data.PageMethodHttpProxy*/
Ext.data.PageMethodHttpProxy = function(method, params, otherConfig) {
var A = { method: 'POST',
timeout: EnjoyWork.AjaxCallTimeOut,
headers: { 'Content-Type': 'application/json;charset=utf-8' }
};
Ext.data.PageMethodHttpProxy.superclass.constructor.call(this, A);
this.pageMethod = method;
this.pageUrl = location.href.split("?")[0];
this.conn = A;
var tempApi = new Object();
if (method != null) {
this.conn.url = this.pageUrl + '/' + method;
tempApi.read = { url: this.conn.url };
}
else {
this.conn.url = null;
}
/*改造传入的API*/
if (otherConfig != null) {
for (var item in otherConfig) {
var old = eval("otherConfig." + item);
old = this.pageUrl + "/" + old;
eval("otherConfig." + item + "='" + old + "'");
}
//应用tempApi没有设置的
Ext.applyIf(tempApi, otherConfig);
}
this.setApi(tempApi);
this.useAjax = !this.conn || !this.conn.events;
this.on("beforeload", function(o, p) {
Ext.applyIf(p, params);
//以下是对传入的参数进行改造
var newObject = new Object();
Ext.apply(newObject, p);
for (var i in p) {
eval("delete p." + i);
}
p["isJson"] = true;
p["jsonData"] = newObject;
}, this);
};
Ext.extend(Ext.data.PageMethodHttpProxy,Ext.data.HttpProxy);

同时需要修改Ext-all.js 查找typeof (params[reader.meta.root]

修改判断条件为

if (typeof (params[reader.meta.root]) === 'object' ||
(params["isJson"] == true && params["jsonData"] != null)) {
            o.jsonData = params["jsonData"];
        } else {
            o.params = params || {};
        }
