问题描述
我收到以下错误：
Microsoft JScript运行时错误：Sys.ArgumentNullException：值不能为null。
参数名称：panelsCreated [1]
同时指向文件中的以下代码（ScriptResource.axd ... [dynamic]）：
I am getting the following error:
Microsoft JScript runtime error: Sys.ArgumentNullException: Value cannot be null.
Parameter name: panelsCreated[1]
while pointing to the following code in file(ScriptResource.axd...[dynamic]):
$type.registerClass('Sys.WebForms.InitializeRequestEventArgs', Sys.CancelEventArgs);
$type = Sys.WebForms.PageLoadedEventArgs = function PageLoadedEventArgs(panelsUpdated, panelsCreated, dataItems) {
/// <summary locid="M:J#Sys.WebForms.PageLoadedEventArgs.#ctor">The arguments for the PageRequestManager's pageLoaded event. The pageLoaded event is raised after the DOM has been updated.</summary>
/// <param name="panelsUpdated" type="Array">An array of UpdatePanels that were updated.</param>
/// <param name="panelsCreated" type="Array">An array of UpdatePanels that were created.</param>
/// <param name="dataItems" type="Object" mayBeNull="true"></param>
var e = Function._validateParams(arguments, [
{name: "panelsUpdated", type: Array},
{name: "panelsCreated", type: Array},
{name: "dataItems", type: Object, mayBeNull: true}
]);
if (e) throw e;
Sys.WebForms.PageLoadedEventArgs.initializeBase(this);
this._panelsUpdated = panelsUpdated;
this._panelsCreated = panelsCreated;
this._dataItems = dataItems || new Object();
}
行：if（e）throw e突出显示。
这个当我在LinkButton上连续第二次或第三次点击时发生。
LinkButton成功调用/执行WebService方法，然后产生错误！
LinkButton代码如下：
with line : " if (e) throw e" highlighted.
This is happening when I click for the 2nd or 3rd time in a row on a LinkButton.
The LinkButton successfully calls/executes a WebService method, and then produces the error!
The LinkButton code is below:

The LinkButton successfully calls/executes a WebService method, and then produces the error!
