如何在静态网页或 asp网页中进行link修改

Question

要从网页中选择<img class="img" id="99999999" style="display:none" />中的“99999999，然后用他去替换<li class="Img"><a href="1235" onclick="this.href=this.href+','+this.innerHTML" target="_blank" charset="113-101-8-1">qweqwewqe</a></li> 中的 1235  ，要循环的，正则比较好。<ul class="video">
            <li class="Img"><a href="1235" onclick="this.href=this.href+','+this.innerHTML" target="_blank" charset="113-101-8-1">qweqwewqe</a></li>
<li class="name"><img class="imgg" id="99999999" style="display:none" /></li>
                      </ul><ul class="video">
            <li class="Img"><a href="1235" onclick="this.href=this.href+','+this.innerHTML" target="_blank" charset="113-101-8-1">qweqwewqe</a></li>
<li class="name"><img class="imgg" id="qweqweqweqwe" style="display:none" /></li>
                      </ul>
<ul class="video">
            <li class="Img"><a href="1235" onclick="this.href=this.href+','+this.innerHTML" target="_blank" charset="113-101-8-1">qweqwewqe</a></li>
<li class="name"><img class="imgg" id="qweqweqweqwe" style="display:none" /></li>
                      </ul>
<ul class="video">
            <li class="Img"><a href="1235" onclick="this.href=this.href+','+this.innerHTML" target="_blank" charset="113-101-8-1">qweqwewqe</a></li>
<li class="name"><img class="imgg" id="qweqweqweqwe" style="display:none" /></li>

var str = gs.replace(r,'$1$3$2');alert(str);
