This time I will bring you Regular expressionsMethods to match URL, phone number, mobile phone, and email address. Notes on methods of using regular expressions to match URL, phone number, mobile phone number, and email addressWhat are they? The following is a practical case. Let’s take a look.

Regular expression, also known as regular expression. (English: Regular Expression, often abbreviated as regex, regexp or RE in code), a concept in computer science. Regular tables are usually used to retrieve and replace text that matches a certain pattern (rule). Let’s introduce the example code of regular expression matching (URL, phone, mobile phone, email) through example code. Let’s take a look!

Without further ado, I will post the code directly for you. The specific code is as follows:

<!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：
//Handsome.W@abc.com
//_hello_world@163.com
//345@mail.some_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');
}
}
