记录一下在之前工作中遇到的手机号码验证的一个问题，主要是用正则表达式来判断手机号是否输入正确。下面附上代码，已经实现过的。

用户注册

var Val={

//正则表达式验证是否为手机号码

isMobile:function(s){return this.test(s,/^1[34578]\d{9}$/)},

isNumber:function(s,d){return !isNaN(s.nodeType==1?s.value:s)&&(!d||!this.test(s,"^-?[0-9]*\\.[0-9]*$"))},

isEmpty:function(s){return !jQuery.isEmptyObject(s)},test:function(s,p){s=s.nodeType==1?s.value:s;return new RegExp(p).test(s)}

};

$(".users").blur(function(){

var v=$(this).val();

var n=$(this).next();

if(!isEmpty(v) && !Val.isMobile(v)){

$(".cellphone_error").html("请输入正确的手机号码！");

$('.account').css('border','1px solid #ff0000');

return;

}if(isEmpty(v)){

$(".cellphone_error").html("请输入账号！");

$('.account').css('border','1px solid #ff0000');

return;

}
