Javascript ASP.NET MVC Ajax:Ajax.Actionlink出错（'；b.apply'；在MicrosoftAjax.js中不是函数）

我对我的ajax测试网站做了一些更改，现在我的ajax.ActionLinks不再工作了！ 相关的ActionLink如下所示：

`

“from”和“meep”函数仅为一行程序，如下所示：

Function meep(ByVal act As String, ByVal cnt As String) As AjaxOptions  
    Return New AjaxOptions With {.UpdateTargetId = "Content", .OnSuccess = "Hash('" + act + "', '" + cnt + "')", .LoadingElementId = "Loader", .OnComplete = "HideLoader", .OnBegin = "EmptyContent('" + act + "', '" + cnt + "')"}  
End Function  
Function from(ByVal act As String, ByVal cnt As String)  
    Return New With {.fromAct = act, .fromCnt = cnt}  
End Function

当我点击上述按钮时，Hash（）执行正常

    function Hash(ghz, ghzz) {
        set_action(ghz);
        set_controller(ghzz);
        window.location.hash = "#" + ghz + "." + ghzz;
    }

EmptyContent也可以工作：

    function EmptyContent(ghz, ghzz) {
        document.getElementById("Loader").style.visibility = "visible";
        document.getElementById("main").style.backgroundColor = "#a0a0a0";
        document.body.style.backgroundColor = "#3c6792";
        return true;
    }

但是，这个过程在某个地方出现了问题。未调用HideLoader（）

这是引发的错误，包括堆栈：

Uncaught exception:TypeError: 'b.apply' is not a function  
Error thrown at line 5, column 583 in <anonymous function: Function.createDelegate>() in http://ajax.sinni800.ath.cx/Scripts/MicrosoftAjax.js:return b.apply(a,arguments)

Uncaught异常：TypeError:“b.apply”不是函数
中第583列第5行抛出错误。它侦听哈希，例如：格式为Action.Controller。另一个：#Mines.Home

我希望有人能找到这个
