本文解决了一个出现在优快云博客页面上的脚本调试错误，通过修改变量声明和使用更简单的名称来避免由长ID引发的问题。

取消“禁用脚本调试”，随便打开一个优快云 Blog显示页面，会出现下面的错误：

调试一下发现是下面的代码有问题：

<SCRIPT type=text/javascript>
<!--
var PostComment.ascx_RequiredFieldValidator2 = document.all ? document.all["PostComment.ascx_RequiredFieldValidator2"] : document.getElementById("PostComment.ascx_RequiredFieldValidator2");
PostComment.ascx_RequiredFieldValidator2.controltovalidate = "PostComment.ascx_tbName";
PostComment.ascx_RequiredFieldValidator2.errormessage = "
请输入尊姓大名";
PostComment.ascx_RequiredFieldValidator2.display = "Dynamic";
PostComment.ascx_RequiredFieldValidator2.evaluationfunction = "RequiredFieldValidatorEvaluateIsValid";
PostComment.ascx_RequiredFieldValidator2.initialvalue = "";
var PostComment.ascx_RequiredFieldValidator3 = document.all ? document.all["PostComment.ascx_RequiredFieldValidator3"] : document.getElementById("PostComment.ascx_RequiredFieldValidator3");
PostComment.ascx_RequiredFieldValidator3.controltovalidate = "PostComment.ascx_tbComment";
PostComment.ascx_RequiredFieldValidator3.errormessage = "
请输入评论";
PostComment.ascx_RequiredFieldValidator3.display = "Dynamic";
PostComment.ascx_RequiredFieldValidator3.evaluationfunction = "RequiredFieldValidatorEvaluateIsValid";
PostComment.ascx_RequiredFieldValidator3.initialvalue = "";
// -->
</SCRIPT>

错误原因是变量声明，变量名声明为PostComment.ascx_RequiredFieldValidator2不正确。

可以这样实现：

<SCRIPT type=text/javascript>
<!--
var PostComment = new Object();
PostComment.ascx_RequiredFieldValidator2 = document.all ? document.all["PostComment.ascx_RequiredFieldValidator2"] : document.getElementById("PostComment.ascx_RequiredFieldValidator2");
PostComment.ascx_RequiredFieldValidator2.controltovalidate = "PostComment.ascx_tbName";
PostComment.ascx_RequiredFieldValidator2.errormessage = "
请输入尊姓大名";
PostComment.ascx_RequiredFieldValidator2.display = "Dynamic";
PostComment.ascx_RequiredFieldValidator2.evaluationfunction = "RequiredFieldValidatorEvaluateIsValid";
PostComment.ascx_RequiredFieldValidator2.initialvalue = "";
PostComment.ascx_RequiredFieldValidator3 = document.all ? document.all["PostComment.ascx_RequiredFieldValidator3"] : document.getElementById("PostComment.ascx_RequiredFieldValidator3");
PostComment.ascx_RequiredFieldValidator3.controltovalidate = "PostComment.ascx_tbComment";
PostComment.ascx_RequiredFieldValidator3.errormessage = "
请输入评论";
PostComment.ascx_RequiredFieldValidator3.display = "Dynamic";
PostComment.ascx_RequiredFieldValidator3.evaluationfunction = "RequiredFieldValidatorEvaluateIsValid";
PostComment.ascx_RequiredFieldValidator3.initialvalue = "";
// -->
</SCRIPT>

又仔细看了一下，好象是回复部分是用ascx用户控件做的，不是手工写的。“PostComment.ascx”是用户控件的ID,大概是这里的问题，建议在aspx中使用ascx时，使用简单名称。

在VS2005下做了个测试，用“PostComment.ascx”作ID是不能编译的，不知道为什么出现这种情况。
