▲正则表达式替换的奇怪问题
为什么下面的代码没有替换成功？
<html xmlns= "http://www.w3.org/1999/xhtml ">
<head>
<title>
css
</title>
</head>
<body>
<div> <a> </a> </div>
<script type= "text/javascript ">
var url = "http://bbs.test.com/read.php?tid=100 ";
var key= "· <a href= 'http://bbs.test.com/read.php?tid=100 '> ×××××××× </a> <br> ";
var reg = new RegExp( "· <a[^ <]*? " + url + "[^> ]*?> .*? </a> <br> ", "i ");
key = key.replace(reg, " ");
alert(key);
</script>
</body>
</html>
[解决办法]
var url = "http://bbs.test.com/read.php\\?tid=100 ";
[解决办法]
url = url.replace(/([\.\?\*\+\|])/g, "\\$1 ");
