Answer 1

<script language=javascript>
var str="Abc <DIV>Edf</DIV> <B>Tyu </B> OPP"
re=/<([^>]*?)>/g
alert(str.replace(re,function(a,b){return "<"+b.toLowerCase()+">"}))
</script>

Answer 2

不错,我刚刚写出这个呢,你们就搞出来了<script language="javascript">
String.prototype.eval_replace = function(pattern,rep){
var str = this.replace(/\\/g,"\\\\");
str = str.replace(/"/g,"\\\"");
str = str.replace(/\r/g,"\\r");
str = str.replace(/\n/g,"\\n");
str = str.replace(pattern,'"+'+rep+'+"');
eval('str="'+str+'";');
return str;
}var str="Abc <DIV>Edf</DIV> <B>Tyu </B> OPP";
alert( str.eval_replace(/(<[^>]*>)/g,'"$1".toLowerCase()') );</script>还是 hbhbhbhbhb1021(天外水火(我要多努力)) 的好一点:)
