Ext.data.PageMethodHttpProxy

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 || {};
        }
