<html>

<head>

<style>

#mydiv{ width:200pxheight:200pxborder:1px solid red}

</style>

<script language="javascript">

window.onload=function(){

var str="aaa111eee222rrr333"

var parter=/(\d+)/g

str=str.replace(parter,"<b>$1</b>")

document.getElementById("mydiv").innerHTML=str

}

</script>

</head>

<body>

<div id=mydiv></div>

</body>

</html>

试了一下,是可以的,不知你哪里写的不对.

<script type="text/javascript">

tip = "thereare some words"

tip = tip.replace(/\s+/g, "\\ ")

alert(tip)

document.write(tip)

</script>
