This paper summarizes the common simple regular expression validation functions of JS with examples. Share it for your reference, as follows:
The following are some common and simple validations, such as those special and complicated situations, which are not considered here
1. Verify the phone number or mobile phone number
/**
* Verify the phone number (mobile phone number + Telephone number)
* @param obj
* @returns {Boolean}
*/
function checkPhoneNum(obj){
if(/^((\d{3}-\d{8}|\d{4}-\d{7,8})|(1[3|5|7|8][0-9]{9}))$/.test(obj)){
return true;
}
}
2. Verify the address (Chinese, English and numbers)
/**
* Verify business address (Chinese, English, numbers)
* @param obj
*/
function checkAddress(obj){
if(/^[\u4e00-\u9fa5a-zA-Z0-9]+$/.test(obj)){
return true;
}
}
3. Verify the user name
/**
* Verify the user name input format
* @param obj
* @returns {Boolean}
*/
function checkUserName(obj){
if(/^[a-zA-Z0-9_-]{3,16}$/.test(obj)){
return true;
}
}
4. Verify the password
/**
* Verify password input format
* @param obj
* @returns {Boolean}
*/
function verifyPassword(obj){
if(/^[a-z0-9_-]{5,18}$/.test(obj)){
return true;
}
}
5. Verify the enterprise tax number
/**
* Verify tax number
* 15 Or 17 Or 18 Or 20 Composed of letters and numbers
* @param obj
* @returns {Boolean}
*/
function checkTax(obj){
if(/^[A-Z0-9]{15}$|^[A-Z0-9]{17}$|^[A-Z0-9]{18}$|^[A-Z0-9]{20}$/.test(obj)){
return true;
}
}
6. Verify the amount
/**
* Verified amount (verifiable Greater than or equal to zero, less than or equal to zero 99999999.99 Number of)
* @param obj
* @returns {Boolean}
*/
function checkMoney(obj){
if(/^([1-9][\d]{0,7}|0)(\.[\d]{1,2})?$/.test(obj)){
return true;
}
}
7. Verify the ID number, including the mainland ID number, and the Hong Kong, Macao and Taiwan ID number. Of course, this is just a simple specification 1. The actual check bits in the last brackets like the Hong Kong ID number need to be based on the previous
The number is calculated according to the weighting algorithm determined by 1 for verification, which is not involved here. If you need special accuracy, you can study it once.
/**
* Verify the ID number of the mainland
* Verify ID number
* ID card number is 15 Bit or 18 The full number of bits, or 18 Bit time preceding 17 Bits are numbers, and last 1 Bits are parity bits, which may be numbers or characters X Or x
* @param obj
*/
function checkIdCard(obj){
if(/(^\d{15}$)|(^\d{18}$)|(^\d{17}(\d|X|x)$)/.test(obj)){
return true;
}
}
/**
* Verify Hong Kong, Macao and Taiwan ID cards
* @param obj
*/
function checkGATIdCard(obj){
var reg1 = /^[A-Z]{1,2}[0-9]{6}[\(|\ ( ]?[0-9A-Z][\)|\ ) ]?$/;// Hong Kong format 1 ( Hong Kong identity card number structure: XYabcdef(z))
var reg2 = /^[A-Z][0-9]{8,12}$/;// Hong Kong format 2 (H60152555)
var reg3 = /^[1|5|7][0-9]{6}[\(|\ ( ]?[0-9A-Z][\)|\ ) ]?$/;// Macao ,8 Number of digits , Excluding date of birth Format is xxxxxxx(x) Note :x All numbers , No English letters The first digit is only 1 , 5 , 7 Beginning with the word
var reg4 = /^[a-zA-Z][0-9]{9}$/;// Taiwan :10 Bit letters and numbers
if(reg1.test(obj) || reg2.test(obj) || reg3.test(obj) || reg4.test(obj)){
return true;
}
}
The following is the authoritative writing of the verification ID number:
/**
* 身份证15位编码规则：dddddd yymmdd xx p
* dddddd：地区码
* yymmdd: 出生年月日
* xx: 顺序类编码，无法确定
* p: 性别，奇数为男，偶数为女
* 身份证18位编码规则：dddddd yyyymmdd xxx y
* dddddd：地区码
* yyyymmdd: 出生年月日
* xxx:顺序类编码，无法确定，奇数为男，偶数为女
* y: 校验码，该位数值可通过前17位计算获得
* 18位号码加权因子为(从右到左) Wi = [ 7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2,1 ]
* 验证位 Y = [ 1, 0, X, 9, 8, 7, 6, 5, 4, 3, 2 ]
* 校验位计算公式：Y_P = mod( ∑(Ai×Wi),11 )
* i为身份证号码从右往左数的 2...18 位; Y_P为脚丫校验码所在校验码数组位置
*

}
Put the above code in an js file, then introduce the js file in the (jsp) page, and then call it
var checkIdCard = new IdCardValidate(id_card);
if(!checkIdCard.IsValid()){
alert(' The ID card you entered is not in the correct format! ');
return;
}
