可能重复:
压缩的javascript可以解压缩

如何将我的javascript从mifified转换为uncompressed？谢谢

我有这个脚本使用正则表达式来检查表单字段是否包含有效的电子邮件地址.请从声明解释我

var emailfilter=/^\w+[\+\.\w-]*@([\w-]+\.)*\w+[\w-]*\.([a-z]{2,4}|\d+)$/i;

谢谢

资源:

<script type="text/javascript">

var emailfilter=/^\w+[\+\.\w-]*@([\w-]+\.)*\w+[\w-]*\.([a-z]{2,4}|\d+)$/i

function checkmail(e){
var returnval=emailfilter.test(e.value)
if (returnval==false){
alert("Please enter a valid email address.")
e.select()
}
return returnval
}

</script>

<form>
<input name="myemail" type="text" style="width: 270px"> <input type="submit" onClick="return checkmail(this.form.myemail)" value="Submit" />

</form>

这是做什么的,为什么这样宣布？
