问题描述

亲爱的名单,


我们正在让一些人试图通过以下形式的电子邮件注册我们的观鸟调查

an *** @ phonecoop.coop ,换句话说,有一个4

字符结尾(其他例子是.info)。


目前,我使用正则表达式来检查带有3个字符的正常电子邮件.....


函数checkEmail() {

var emailVar = document.shorter.email.value;

if(emailVar.length> 0){

if

(/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\\\\ ,3})+ $ / .test(document.shorter.email

..value))

{

return(true)< br $>
}

其他

{

提醒(无效的电子邮件地址!请重新输入。 ;)

document.shorter.email.select();

}

}

}

有没有人知道可以处理e类型的类似功能邮件我

上面描述了4个字符?我对regexp正在做的事情的了解有点暂时无限(没有 - 对我来说看起来很乱,但它确实有用

很好!)


干杯

返回(true)

}

亲爱的清单,

我们正在获得一个很少有人试图通过以下形式的电子邮件注册我们的观鸟调查
an***@phonecoop.coop ,in字符结尾为4

Dear list,

we are getting a few folk trying to register for our birdwatching surveys
with emails of the form: an***@phonecoop.coop, in other words with a 4
character ending (other examples are .info).

Currently, I use a regexp to check on ''normal'' emails with 3 chars.....

function checkEmail() {
var emailVar = document.shorter.email.value;
if (emailVar.length > 0){
if
(/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/.test(document.shorter.email
..value))
{
return (true)
}
else
{
alert("Invalid E-mail Address! Please re-enter.")
document.shorter.email.select();
}
}
}
Does anyone know of a similar function that can handle the type of e-mail I
described above with 4 chars? My knowledge of what regexp is doing is a tad
limited to say the least (none - looks gibberish to me but it does work
well!)

Cheers
Iain
