JQuery错误尝试使Ajax调用

Question

我正在处理SharePoint项目。我想使用JQuery从主页进行ajax调用。但是，当我拨打电话时，我得到“Array.prototype.slice：'this'不是JavaScript对象”错误。

下面是我使用的文件的广告代码： homepage.js/

$(document).ready(function() { 

    Ajax.GetWeather(); 
}); 

Ajax.js/

ns.GetWeather = function() { 
    alert("yep"); 
    $.ajax({ 
     data: $.extend({ 
      Function: "GetWeather" 
     }), 
     type: 'POST', 
     success: function (json) { 

      //$('#ContentMain').append(json.LoginMainHtml); 
      //$('#ContentSide').append(json.LoginSideHtml); 
      alert("hmmmm"); 
      ns.HideUpdateStatus(); 
     } 
    }); 
};

     context.Response.ContentType = "text/json"; 

     // Get the function name from the request GET/POST parameters 
     string function = context.Request["Function"]; 
    context.Response.Write(function);

此：

data: $.extend({ 
     Function: "GetWeather" 
    }) 

应该是：

data: $.extend({},{ 
     "Function": "GetWeather" 
    }) 

或：

data: {"Function":"GetWeather"} 

或：

data: "Function=GetWeather"
