[javascript] replace 替换问题

peterdocter

原来是样：
<a href="/cgi-bin/by?m=1336204673" onMouseOut="MM_swapImgRestore()" onMouseOver="MM_swapImage('Image18','','/images/submenu/button10_logout_over.gif',1)" target="_parent">2</a>
替换成样：
<a href="/cgi-bin/by?m=460225299" onmouseout="MM_swapImgRestore()" onmouseover="MM_swapImage('Image18','','/images/submenu/button10_logout_over.gif',1)" onclick="function end(){var s;var url=self.location.href;var pos=url.lastIndexOf('/');var s=url.substr('0',pos);var bin=s+'/login';top.location=bin;}end();return false;" target="_parent">1</a>

m的值会变化的！

主要实现添加这段代码：
onclick="function end(){var s;var url=self.location.href;var pos=url.lastIndexOf('/');var s=url.substr('0',pos);var bin=s+'/login';top.location=bin;}end();return false;"

<script>
alert(document.body.innerHTML.replace(/有什么正则表达？/,替换内容));
</script>
