javascript中的replaceAll功能

 
javascript中的replaceAll功能。 

請注意/Microsoft/g，就是這個小g

在本例中，我們將執行一次全域替換，每當 "Microsoft" 被找到，它就被替換為 "W3C"：

<script type="text/javascript">

var str="Welcome to Microsoft! "
str=str + "We are proud to
announce that Microsoft has "
str=str + "one of the largest Web
Developers sites in the world."

document.write(str.replace(/Microsoft/g, "W3C"))

</script>

輸出：

Welcome to W3C! We are proud to announce that W3C
has one of the
largest Web Developers sites in the world.
