fwREST v0.4.5

fwREST是用于CRM2011中使用REST访问OData服务进行数据操作的帮助js函数集。
使用时请用如下方式进行实例化：

var  r = new fwREST();

如果返回结果对象的.error != undefined 刚表明有错误，请使用 .error.message.value获取错误内容。

===================================================================*/
function fwREST(url) {
    var self = this;
    self.ServerUrl = null;
    if (url) {
        self.ServerUrl = url;
    } else {
        if (window.Xrm) {
            self.ServerUrl = Xrm.Page.context.getClientUrl();
        }
    }
    self.Async = false;
}
/*=================================================================

方法：fwREST.create(entityname,jsondata)
说明：发送json形式的请求，用于创建记录。

entityname      字符串:实体名，需要使用逻辑名，区分大小写。如Account,New_test等
jsondata        字符串：JSON形式的请求内容，如"{'Name':'张三'}"
返回：object类型
