rest语法：

var context = _spPageContextInfo;

this.SiteUrl = context.webServerRelativeUrl;

GetExcelData: function (fileName,callbackMethod) {

var method = "ExcelRest.aspx/Shared%20Documents/" + fileName + "/model/Ranges('Sheet1!A1%7cV20')?$format=json";

url:(this.UriList.GetExcelData + "/" + method).then(callbackMethod);

//使用ajax请求，返回一个JSON格式的数组

}
