<script>
function matchDemo(){
var s;
var re = new RegExp("^a");
var str = "an A";
var arr = re.exec(str);
s = "$1 contains: " + RegExp.$1 + "\n";
s += "$2 contains: " + RegExp.$2 + "\n";
s += "$3 contains: " + RegExp.$3;
return(s);
}
</script>
<input type="button" name="button" value="button" onClick="alert(matchDemo());" />
这个写法怎么没有结果(匹配)
