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

/**

$.validator.addMethod("isMobile", function (value, element) {
    var reg = /^((1[3-8][0-9])+\d{8})$/;
    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");
/**

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");
