我是靠谱客的博主单薄石头，最近开发中收集的这篇文章主要介绍validator验证控件使用代码，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

下面是js代码（在绑定对象的时候感觉很不优雅，希望高人能指点一二啊！）

复制代码代码如下:

 
function validator(obj,option){//验证对象 
var self = this; 
if(!(self instanceof validator)) 
return new validator(obj,option); 
self.source={'mobile':'^(13|14|15|18)[0-9]{9}$','postcode':'^\d{6}$','integer':'^-?\d*$','email':'^\w+((-\w+)|(\.\w+))*\@[A-Za-z0-9]+((\.|-)[A-Za-z0-9]+)*\.[A-Za-z0-9]+$','url':'^http[s]?:\/\/([\w-]+\.)+[\w-]+([\w-./?%&=]*)?$'}; 
for(var i in self.source){ 
if(i==option.type) 
self.type=self.source[i]; 
} 
self.tag=2; 
self.input=obj; 
self.options=option; 
self.tip=document.getElementById(self.options.tips); 
self.text=self.tip.innerHTML; 
self.init(obj); 
} 
validator.prototype.init=function(o){ 
var self=this; 
addEvent(o,'focus',function(){ 
self.focus(); 
}); 
addEvent(o,'blur',function(){ 
self.valid(); 
}); 
} 
validator.prototype.valid=function(){ 
var self=this; 
var reg=self.options.reg||self.type; 
if(new RegExp(reg).test(self.input.value.replace(/s/ig,''))){ 
self.tip.className='validator_oncorrect'; 
self.tip.innerHTML='输入正确'; 
self.tag=1; 
}else{ 
self.tip.className='validator_onerror'; 
self.tip.innerHTML='对不起，您输入的内容不符合规则！'; 
self.tag=0; 
} 
} 
validator.prototype.focus=function(){ 
this.tip.className='validator_onfocus'; 
this.tip.innerHTML=this.text; 
} 
function addEvent(el,type,fn){ //绑定事件 
if(el.attachEvent) { 
el['e'+type+fn] = fn; //IE下拷贝元素引用,使this指向el对象而不是window 
el[type+fn] = function(){el['e'+type+fn](window.event);} 
el.attachEvent('on'+type, el[type+fn]); 
}else 
el.addEventListener(type, fn, false); 
} 
//页面调用方法 
var inputs=document.getElementsByTagName('input');//这里的写法感觉怪怪的，不够优雅，暂时也没找到优化的办法 
var arr=[]; 
arr[0]=validator(inputs[0],{type:'postcode',tips:'m1'}); 
arr[1]=validator(inputs[1],{type:'url',tips:'m2'}); 
arr[2]=validator(inputs[2],{type:'email',tips:'m3'}); 
arr[3]=validator(inputs[3],{type:'mobile',tips:'m4'}); 
arr[4]=validator(inputs[4],{type:'integer',tips:'m5',reg:'^-?\d*$'}); 
function submitForm(){//提交表单过滤 
var l=arr.length; 
for(var i in arr){ 
if(arr[i].tag==1) 
l--; 
else if(arr[i].tag==2){ 
arr[i].valid(); 
} 
} 
if(l!=0)return false; 
} 

以下是页面demo，可能缺少一个小图标，汗，不知道怎么发可执行的代码。
