未结束的字符串常量 javascript

[never_give_up520]

catch (Exception ex)

ClientScriptManager bs = Page.ClientScript;
StringBuilder ScriptContent = new StringBuilder();

ScriptContent.Append("<script type='text/javascript'>");

正确的情况下，应该生成如下 HTML 代码：

<script type='text/javascript'>alert('error message here');</script >

[never_give_up520]

连一下数据库故意让它报错,捕获的时候就出现这样的情况.

[never_give_up520]

写成这样与报错
Response.Write("<script>alert('"+ex.Message.ToString()+"');</script>");
仍然是错误:未结束的字符串常量
关键是弹不出如下的这此文字.

是不是这些错误描述文字引发了javascript的异常????

[never_give_up520]

这么长时间没人给出正确的解释

[exiori]

你的编码方式是什么。还有没有其它的JS代码。很可能是其它代码的问题。编码方式也会引起这个问题。

[TonyTonyQ]

额，你这样的错误信息肯定有JavaScript错误的，有"\"在。
写成这样看看：

Response.Write(" <script >alert( '"+ HttpUtility.HTMLEncode(ex.Message.ToString())+" '); </script >");

[小明aa]

catch (Exception ex)
{
Type t = GetType();
ClientScriptManager bs = Page.ClientScript;
StringBuilder ScriptContent = new StringBuilder();

ScriptContent.Append(" <script type= 'text/javascript ' >");
ScriptContent.Append("alert(replace( '"+ex.Message.ToString()+"');");
ScriptContent.Append(" </script >");
string key="SearchError";
if (!bs.IsClientScriptBlockRegistered(t,key))
{
bs.RegisterClientScriptBlock(t, "SearchError", ScriptContent.ToString());
}
}

大哥你试了吗?根本就不好用.

[sonce8]

仔細檢查下引號吧！

ex.Message有换行，‘等符号，转成js要替换

[孟子E章]

catch (Exception ex)
{
Type t = GetType();
ClientScriptManager bs = Page.ClientScript;
StringBuilder ScriptContent = new StringBuilder();
string rrr = ex.Message.ToString();
rrr = rrr.Replace("\r\n","");
rrr = rrr.Replace("\n","");
rrr = rrr.Replace("\r","");
rrr = rrr.Replace(" '","\ '");

ScriptContent.Append(" <script type= 'text/javascript ' >");
ScriptContent.Append("alert('"+ rrr +"');");
ScriptContent.Append("</script>");
string key="SearchError";
if (!bs.IsClientScriptBlockRegistered(t,key))
{
bs.RegisterClientScriptBlock(t, "SearchError", ScriptContent.ToString());
}
}

谢谢老大,今天下班了,我再调一调.

[nchen123]

ToString()+");}");

=>

ToString()+"');}");

'text/javascript '
=>
'text/javascript'

小错误很多。

[uephee]

是不是异常的Message里有什么字符，查看源代码，看看脚本到底是什么

[never_give_up520]

着急发错了
如下
catch (Exception ex)
{
Type t = GetType();
ClientScriptManager bs = Page.ClientScript;
StringBuilder ScriptContent = new StringBuilder();

ScriptContent.Append("<script type='text/javascript'>");
ScriptContent.Append("{alert('"+ex.Message.ToString()+");}");
ScriptContent.Append("</script>");
string key="SearchError";
if (!bs.IsClientScriptBlockRegistered(t,key))
{
bs.RegisterClientScriptBlock(t, "SearchError", ScriptContent.ToString());
}
}

[uephee]

你输出的不是函数，没有function，为什么还要加大括号{}

试试用ScriptContent.AppendFormat()函数，代码会好看很多

[never_give_up520]

rrr = rrr.Replace("\r\n","");
rrr = rrr.Replace("\n","");
rrr = rrr.Replace("\r","");
rrr = rrr.Replace(" '",@"\ '");
老大能否告诉我这几个的含义

[孟子E章]

就是去掉换行，添加转义，
