jquery自定义表单验证插件 427 2024-02-15

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("*", /[wW]+/);
map.put("*6-16", /^[wW]{6,16}$/);
map.put("n", /^d+$/);
map.put("n6-16", /^d{6,16}$/);
map.put("s", /^[u4E00-u9FA5uf900-ufa2dw.s]+$/);
map.put("s6-16", /^[u4E00-u9FA5uf900-ufa2dw.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

    }
    if($("."+tipId).is(":hidden")){
    //如果是隐藏的菜单不校验
    continue;
    }
    //获取返回的正则表达式
    var reg = Validform.matchReg(reType[i]);

  entrys[i] = {
   key : this.keys[i],
   value : this.data[i]
  };
  }
  return entrys;
 };

 /**
  * 判断Map是否为空
  */
 this.isEmpty = function() {
  return this.keys.length == 0;
 };

 /**
  * 获取键值对数量
  */
 this.size = function(){
  return this.keys.length;
 };

 /**
  * 重写toString 
  */
 this.toString = function(){
  var s = "{";
  for(var i=0;i<this.keys.length;i++,s+=','){
  var k = this.keys[i];
  s += k+"="+this.data[k];
  }
  s+="}";
  return s;
 };
}

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。
