jquery自定义表单验证插件

本文实例为大家分享了jquery表单验证插件，供大家参考，具体内容如下

//正则表达式
var map = new Map();
map.put("*", /[\w\W]+/);
map.put("*6-16", /^[\w\W]{6,16}$/);
map.put("n", /^\d+$/);
map.put("n6-16", /^\d{6,16}$/);
map.put("s", /^[\u4E00-\u9FA5\uf900-\ufa2d\w\.\s]+$/);
map.put("s6-16", /^[\u4E00-\u9FA5\uf900-\ufa2d\w\.\s]{6,16}$/);
map.put("p", /^[0-9]{6}$/);//邮编
map.put("m", /^13[0-9]{9}$|14[0-9]{9}|15[0-9]{9}$|18[0-9]{9}$/);//手机号码
map.put("e", /^\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$/);//email
map.put("url", /^(http|https):\/\/(\w+:\/\/)?\w+(\.\w+)+.*$/);//url地址
map.put("image", /^(http|https):\/\/.*(.JPEG|.jpeg|.JPG|.jpg|.GIF|.gif|.BMP|.bmp|.PNG|.png)$/);//图片
map.put("integer", /^[1-9]\d*$/);//大于0的正整数
map.put("hj", /(\S*?) [^>]*>.*?<\/\1>|<.*?/);//过滤html标签和javascript标签

(function($,win){
 Validform = {
 matchReg : function(datatype){
  //匹配返回正则表达式 有3个比较特殊 所有特殊处理一下
  //这3个是因为有长度判断 要动态修改正则表达式
  var reg1 = /^\*\d{1,}-\d{1,}$/;

 };
}

这个是一个js插件保存.js引用就可以了，特点灵活可以自定义校验内容原理使用正则表达式，对于隐藏的表单不校验

这个是html的用法不用考虑其他的就是html代码

 function validateForm1(){
 var flag=HaHaUtil.checkFrom('detailDataForm');
 return flag;
 }

这个是from表单之前的数据校验的函数。
