正则表达式匹配(URL、电话、手机、邮箱)的实例代码
正则表达式，又称规则表达式。（英语：Regular Expression，在代码中常简写为regex、regexp或RE），计算机科学的一个概念。正则表通常被用来检索、替换那些符合某个模式(规则)的文本。下面通过实例代码给大家介绍正则表达式匹配(URL、电话、手机、邮箱)的实例代码，一起看看吧！
废话不多说了，直接给大家贴代码了，具体代码如下所示：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>正则验证</title>
</head>
<body>
<input type="text" name="" id="text">
<input type="button" name="" id="btn" value="点击">
<span></span>
</body>
<script type="text/javascript">
var text = document.getElementById('text');
var btn = document.getElementById('btn');
//1、url示例：
//https://www.baidu.com/s?wd=%E5%88%98%E5%BE%B7%E5%8D%8E&rsv_spt=1&rsv_iqid=0x9601edc200017402&issp=1&f=8&rsv_bp=1&rsv_idx=2&ie=utf-8&rqlang=cn&tn=baiduhome_pg&rsv_enter=1&oq=javascript%2520%25E9%259A%25BE%25E9%25A2%2598&inputT=1256&rsv_t=7da5GmMhTie86h8qaOiaV047P9TkJunMjrkmK%2BNLA%2FuJs3bMG%2Bj52w%2F6IxHge5MB%2B%2B%2Fw&rsv_pq=c270d50b00019cae&rsv_sug3=21&rsv_sug1=19&rsv_sug7=100&rsv_sug2=0&rsv_sug4=1818
//2、电话示例：
//13800138000
//+ 8610 - 59926666
//+ (1)533- 222 - 334
//010 - 59926666
//037132376865
//3、电子邮件示例：
//[email protected]
//[email protected]
//[email protected]_domain_name.com.uk
// var regexp=/^([0-9a-zA-Z_.-])+@([0-9a-zA-Z_-])+(\.([a-zA-Z_-])+)+$/;//邮箱
// var regexp=/(https?.*?\.(:?cn\b|com\b|net\b|org\b|gov\b)(?!\.))/;//URL
// var regexp=/\+?\d{3,4}-?\d{7,8}/; // 010-59926666 8610-59926666 037132376865
// var regexp =/\+\(\d\)(\d{3}-){2}\d{3}/;//+(1)533-222-334
// var regexp=/(1[34578]\d{9})|(\+?\d{3,4}-?\d{7,8})|(\+\(\d\)(\d{3}-){2}\d{3})/;//电话号码 13800138000 010-59926666 8610-59926666 037132376865 +(1)533-222-334
var regexp=/(([0-9a-zA-Z_.-])+@([0-9a-zA-Z_-])+(\.([a-zA-Z_-])+)+)|((https?.*?\.(:?cn\b|com\b|net\b|org\b|gov\b)(?!\.)))|(1[34578]\d{9})|(\+?\d{3,4}-?\d{7,8})|(\+\(\d\)(\d{3}-){2}\d{3})/;
btn.onclick = function(){
if(regexp.test(text.value)){
alert('验证通过');
text.value="";
}else{
alert('验证没通过');
}
}
</script>
