Javascript语言的ASP.NET [英] Javascript in asp .Net
本文介绍了Javascript语言的ASP.NET的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我收到WebResource错误在我asp.Net页：
VAR __pendingCallbacks =新的Array（）;微软JScript运行时错误：'阵'是未定义
我不知道什么可能导致这种情况发生。 JavaScript不本身的阵列部分？任何帮助将是AP preciated。
修改
问题是，这并不是code，我写的，它的建成在asp.Net页面结构。
修改
问题只出现在IE9中，只有当在IE9模式下运行（不兼容）

解决方案
这是因为我们有这个设置
＆LT;可折叠的面板＆gt;
＆LT; IFRAME＆GT;
＆LT;脚本＆GT;
＆LT; / SCRIPT＆GT;
＆LT; / IFRAME＆GT;
＆LT; /可折叠面板＆gt;
在页面加载后，正在显示面板迫使iframe中的脚本通过DOM拖动装载的JavaScript库之前。这似乎是在变化的IE9制成。我还没有罚款解决这个问题的一种方式，但至少我知道的原因。临时解决方法是使用的情况下，任何人meta标签运行到这个问题，迫使网页的兼容IE8。
I'm getting WebResource error in my asp.Net page:
var __pendingCallbacks = new Array();
Microsoft JScript runtime error: 'Array' is undefined
I have no idea what might cause this to happen. Isn't Array part of Javascript itself? Any help would be appreciated.
EDIT The problem is that this isn't code that I wrote, it's built into the page structure in asp.Net.
EDIT The problem only occurs in IE9 and only when run in IE9 mode (not compatibility)
Code: (This is dynamically generated code, sorry for the length. Problem is about halfway down)
function WebForm_PostBackOptions(eventTarget, eventArgument, validation, validationGroup, actionUrl, trackFocus, clientSubmit) {
this.eventTarget = eventTarget;
this.eventArgument = eventArgument;

xmlRequestFrame.document.forms[0].appendChild(callbackIndexFieldElement);
xmlRequestFrame.document.forms[0].submit();
}
}, 10);
}
解决方案
This happens because we have this setup
<collapsible panel>
<iframe>
<script>
</script>
</iframe>
</collapsible panel>
When the page loads, the panel being shown forces the script inside the iframe to be dragged through the DOM before the javascript libraries are loaded. This seems to be a change in that was made for IE9. I have yet to fine a way around this issue but at least I know the cause. A temporary workaround is to force the compatibility of the page to IE8 using a meta tag in case anybody else runs into this issue.
