求一正则表达式

Question

<script language=javascript>
var b ="sshahhshashhsh\\\"saaasss";
alert("<font color=red>"+b+"</font>")
</script>正则??

Answer 1

<script language=javascript>
var b ="sshahhshashhsh\\\"saaasss";
var a = "sshahhshashhsh\"saaasss";
alert(b.replace(/^(.*?)$/,"<font color=red>$1</font>"))
alert(a.replace(/^(.*?)$/,"<font color=red>$1</font>"))
</script>

Answer 2

我的意思是想代码中的常量红色表示的<textarea name="t1" rows="20" style="width:1024px;">
var a = "sshahhshashhsh\"saaasss";
var b ="sshahhshashhsh\\\"saaasss";
</textarea>是 t1.value 内容

Answer 3

正则不太熟，看这样行不
<textarea name="t1" rows="20" style="width:1024px;">
var a = "sshahhshashhsh\"saaasss1";
var b ="sshahhshashhsh\\\"saaasss2";
</textarea>
<SCRIPT LANGUAGE="JavaScript">
<!--
var str = document.all.t1.value;
alert(str.replace(/(=\s*\")(.*?)(\"\;)/ig,"$1<font color=red>$2</font>$3"))
//-->
</SCRIPT>

上面还有个bug,该怎么样解决？当var a="sassadasasssdsd\";ddasdassd";
时显示是不对的

Answer 5

<textarea name="t1" rows="20" style="width:1024px;">
var a = "sshahhshashhsh\";saaasss1";
var b ="sshahhshashhsh\\\"saaasss2";
</textarea>
<SCRIPT LANGUAGE="JavaScript">
<!--
var str = document.all.t1.value;
alert(str.replace(/(=\s*\")(.*?)(\";\r\n)/ig,"$1<font color=red>$2</font>$3"))
//-->
</SCRIPT>
