兄弟们,关于引号的问题,折磨死了,高手请进.

<td><input type="radio" value="<%=str%>" name="UserID"></td>
在一个表格中我显示了一个字符串，str, str中包含双引号。

可我用javascript取出来之后，结果总是错误的。
document.form1.UserID.value

如果str = "abcd\"mmn";
取出来的结果却是"abcd\",

总是把第二个双引号后面的字符截掉，不知道为何会这样？

<td><input type="radio" value='<%=str%>' name="UserID"></td>

<td><input type="radio" value='abcd"mmn' name="UserID"></td>
<td><input type="radio" value="abcd'mmn" name="UserID"></td>

Yes
注意javascript 中的字符串的引用! 单引号和双引号

后台字符串输出到前台要经过转码
如果是jsp
请用以下的工具进行转码：
输出到html里,用htmlEncoder
输出到js里,用jsEncoder

xjdawu(无法界定) ,如果字符串中既有单引号，又有双引号，如何处理？？

[xtuwz]

我認為循環有問題呀,一般都是少了一次.
或是分界符有點問題,在前的放在後邊,在後的放在前邊

[xxuu503]

在vbs过滤：

Replace(str,"&","&")
Replace(str,"<","<")
Replace(str,">","&rt")
Replace(str,"\"",""")
Replace(str,"'","'")
Replace(str," "," ")
Replace(str,"\r\n","<br>")
Replace(str,"\r","<br>")
Replace(str,"\n","<br>")
