求一段正则表达 急啊！

[keatkeat1987]

就是把一段 string 里面的 <script>alert("a");</script>
换成 <script>alert("a");</script>

有个小要求就是 string 里面其它的 html tag 如 <p> <div> 都不要换，只针对 <script>内容而已

[似梦飞花]

var a='<script>alert("a");<'+'/script>'; a=a.replace(/<\/?script>/g,function(x){ return x.replace("<","<").replace(">",'>'); }) alert(a);

<script type="text/javascript">
    var a='<script type="text/javascript">alert("a");<\/script>';
    a=a.replace(/<\/?script[^>]*>/g,function(x){
        return x.replace(/</g,"<").replace(/>/g,">").replace(/"/g,""");
    });
</script>

var a='<script>alert("a");<'+'/script>';
alert(a.replace(/\</g,"<").replace(/\>/g,'>'));

还要考虑：<script type="text/javascript">XXOO</script>

<script type="text/javascript">
    var a='<script type="text/javascript">alert("a");<\/script>';
    a=a.replace(/<\/?script[^>]*>/g,function(x){
        return x.replace(/</g,"<").replace(/>/g,">").replace(/"/g,""");
    });
    alert(a);
</script>
