电子邮件地址或域名的Jqueryvalidation
用户可以输入电子邮件地址或域名。 我如何使用jQuery Validation Pluginvalidation这一点？
可接受的值：电子邮件地址/域名
例如： test@example.com或sample.com
我需要在同一文本框中validation域名。
$(document).ready(function(){ jQuery.validator.addMethod("valDomain",function(nname) { name = nname.replace('http://',''); nname = nname.replace('https://',''); var arr = new Array( '.com','.net','.org','.biz','.coop','.info','.museum','.name', '.pro','.edu','.gov','.int','.mil','.ac','.ad','.ae','.af','.ag', '.ai','.al','.am','.an','.ao','.aq','.ar','.as','.at','.au','.aw', '.az','.ba','.bb','.bd','.be','.bf','.bg','.bh','.bi','.bj','.bm', '.bn','.bo','.br','.bs','.bt','.bv','.bw','.by','.bz','.ca','.cc', '.cd','.cf','.cg','.ch','.ci','.ck','.cl','.cm','.cn','.co','.cr', '.cu','.cv','.cx','.cy','.cz','.de','.dj','.dk','.dm','.do','.dz', '.ec','.ee','.eg','.eh','.er','.es','.et','.fi','.fj','.fk','.fm', '.fo','.fr','.ga','.gd','.ge','.gf','.gg','.gh','.gi','.gl','.gm', '.gn','.gp','.gq','.gr','.gs','.gt','.gu','.gv','.gy','.hk','.hm', '.hn','.hr','.ht','.hu','.id','.ie','.il','.im','.in','.io','.iq', '.ir','.is','.it','.je','.jm','.jo','.jp','.ke','.kg','.kh','.ki', '.km','.kn','.kp','.kr','.kw','.ky','.kz','.la','.lb','.lc','.li', '.lk','.lr','.ls','.lt','.lu','.lv','.ly','.ma','.mc','.md','.mg', '.mh','.mk','.ml','.mm','.mn','.mo','.mp','.mq','.mr','.ms','.mt', '.mu','.mv','.mw','.mx','.my','.mz','.na','.nc','.ne','.nf','.ng', '.ni','.nl','.no','.np','.nr','.nu','.nz','.om','.pa','.pe','.pf', '.pg','.ph','.pk','.pl','.pm','.pn','.pr','.ps','.pt','.pw','.py', '.qa','.re','.ro','.rw','.ru','.sa','.sb','.sc','.sd','.se','.sg', '.sh','.si','.sj','.sk','.sl','.sm','.sn','.so','.sr','.st','.sv', '.sy','.sz','.tc','.td','.tf','.tg','.th','.tj','.tk','.tm','.tn', '.to','.tp','.tr','.tt','.tv','.tw','.tz','.ua','.ug','.uk','.um', '.us','.uy','.uz','.va','.vc','.ve','.vg','.vi','.vn','.vu','.ws', '.wf','.ye','.yt','.yu','.za','.zm','.zw'); var mai = nname; var val = true; var dot = mai.lastIndexOf("."); var dname = mai.substring(0,dot); var ext = mai.substring(dot,mai.length); //alert(ext); if(dot>2 && dot<57) { for(var i=0; i<arr.length; i++) { if(ext == arr[i]) { val = true; break; } else { val = false; } } if(val == false) { return false; } else { for(var j=0; j 47 && hh 64 && hh 96 && hh<123) || hh==45 || hh==46) { if((j==0 || j==dname.length-1) && hh == 45) { return false; } } else { return false; } } } } else { return false; } return true; }, 'Invalid domain name.'); $("#form_search").validate({ rules: { field: { required: true, valDomain:true } } }); });
添加validation方法，检查值是否为电子邮件/url。
jQuery.validator.addMethod("emailordomain", function(value, element) { return this.optional(element) || /^\w+@[a-zA-Z_]+?\.[a-zA-Z]{2,3}$/.test(value) || /[-a-zA-Z0-9@:%_\+.~#?&//=]{2,256}\.[az]{2,4}\b(\/[-a-zA-Z0-9@:%_\+.~#?&//=]*)?/.test(value); }, "Please specify the correct url/email"); $( "#myform" ).validate({ rules: { field: { required: true, emailordomain: true } } });
你可以用自己的正则表达式代替:)
DEMO
你可以用简单的javascript +正则表达式来完成它
function function validateMail(email) { var expr = /^([a-zA-Z0-9_.+-])+\@(([a-zA-Z0-9-])+\.)+([a-zA-Z0-9]{2,4})+$/; return expr.test(email); }
