A collection of commonly used regular expressions in js

黄舟Original: 2017-02-22 13:28:271498browse

The following contains some regular expressions that I often use, because almost all the places where regular expressions are used in work scenarios are related to the verification of the validate plug-in,

So The following regular rules are also an extension of $.validator.addMethod():

validate: http://www.php.cn/

Phone verification

/**
 * 手机
 * */
$.validator.addMethod("isMobile", function (value, element) {
    var reg = /^((1[3-8][0-9])+\d{8})$/;
    return this.optional(element) || (reg.test(value));
}, "手机格式不正确");
/**
 * 号码，固话与手机都可以
 * */
jQuery.validator.addMethod("allPhone", function(v, e) {
        return this.optional(e) || /^(([0\+]\d{2,3}-)?(0\d{2,3})-)?(\d{7,8})(-(\d{3,}))?$/.test(v)||/^(1(([35][0-9])|(47)|[8][01236789]))\d{8}$/.test(v);},
    "请输入正确的号码:区号-电话号码/手机号");
/**
 * 固话、传真,传真格式与固话是一样的
 * */
jQuery.validator.addMethod("isTel", function(v, e) { return this.optional(e) || /^(([0\+]\d{2,3}-)?(0\d{2,3})-)?(\d{7,8})(-(\d{3,}))?$/.test(v);}, "请输入正确的电话号码");
/**
 * 手机
 * */
$.validator.addMethod("isMobile", function (value, element) {
    var reg = /^((1[3-8][0-9])+\d{8})$/;
    return this.optional(element) || (reg.test(value));
}, "手机格式不正确");

/**
 * 号码，固话与手机都可以
 * */
jQuery.validator.addMethod("allPhone", function(v, e) {
        return this.optional(e) || /^(([0\+]\d{2,3}-)?(0\d{2,3})-)?(\d{7,8})(-(\d{3,}))?$/.test(v)||/^(1(([35][0-9])|(47)|[8][01236789]))\d{8}$/.test(v);},
    "请输入正确的号码:区号-电话号码/手机号");

/**
 * 固话、传真,传真格式与固话是一样的
 * */
jQuery.validator.addMethod("isTel", function(v, e) { return this.optional(e) || /^(([0\+]\d{2,3}-)?(0\d{2,3})-)?(\d{7,8})(-(\d{3,}))?$/.test(v);}, "请输入正确的电话号码");

Number Verification

/**

 * */
$.validator.addMethod("ispositivenum", function (value, element) {
    var reg = /^([0]|[1-9]\d*)$/;
    return this.optional(element) || (reg.test(value));
}, "请输入正整数");
/**

 * */
$.validator.addMethod("pFloatTwo", function (value, element) {
    return this.optional(element) || (/^([1-9]\d*|[0])(\.\d{1,2})?$/.test(value));
}, "请输入正数，最多保留两位小数");
/**
 * 价格（包括浮点数）最大值99999.99
 * */
$.validator.addMethod("price", function (value, element) {
    return this.optional(element) || (value>0&&(/^([1-9]\d{0,4}|[0])(\.\d{1,2})?$/.test(value)));
}, "请输入正数，最大值99999.99，最多保留两位小数");
/**
 * 规格
 * */
$.validator.addMethod("size", function (value, element) {
    var reg = /^[1-9]\d{0,4}$/;
    return this.optional(element) || (reg.test(value));
}, "请输入正整数，最大值99999");
/**

 * */
$.validator.addMethod("qty", function (value, element) {
    return this.optional(element) || (value>0 && (/^([1-9]\d{0,4}|[0])(\.\d{1,3})?$/.test(value)));
}, "请输入正数，最大值99999.999，最多保留三位小数");




/**

$.validator.addMethod("ispositivenum", function (value, element) {

License Plate Number Verification

/**

$.validator.addMethod("isCarNo", function(value, element){
    var reg = /^[\u4e00-\u9fa5]{1}[a-zA-Z]{1}[a-zA-Z_0-9]{4}[a-zA-Z_0-9_\u4e00-\u9fa5]$|^[a-zA-Z]{2}\d{7}$ /;
    return this.optional(element) || (reg.test(value));

ID card number verification includes 15-digit and 18-digit ID card verification
