jquery验证插件进一步进行封装（easy-check）

1、easy-check.js，核心代码如下（要运行demo或有什么问题，可以留言）

 

var easyCheck;
var defaultOptions = {
	showClass:'show_validate_div', 	//提示信息显示容器class
	parentTag:'tr',				   	//输入框和提示信息共同父类标签
	successImage:'./right.gif',	   	//验证成功提示图片路径
	ErrorImage:'./error.gif',	   	//验证失败提示图片路径
	imageHeight:23,	   				//提示图片高度
	imageWidth:23,	   				//提示图片宽带
	autoAjax:false,	   				//是否鼠标blur是ajax验证（如果否，则提交时ajax验证）
}
var settings,showClass,parentTag,successImage,ErrorImage,imageHeight,imageWidth,autoAjax;
$.easyCheck = function(options){
	settings =  $.extend(defaultOptions,options);
	showClass = settings.showClass; 
	parentTag = settings.parentTag; 
	successImage = settings.successImage; 
	ErrorImage = settings.ErrorImage; 
	imageHeight = settings.imageHeight; 
	imageWidth = settings.imageWidth; 
	autoAjax = settings.autoAjax;
	
	 $('input').focus(function(){
        var show_div_node = $(this).parents(parentTag).find('.' + showClass);
		var input_val = $(this).val();
		var objItem = $(this);
		if(input_val=='' || input_val==null){
			console.info("这是info");
			showMessage(objItem.attr('default'),show_div_node,false,false);
		}
        show_div_node.show();
		
    }).blur(function(){
    
        var show_div_node = $(this).parents(parentTag).find('.' + showClass);
        var input_val = $(this).val();
        var isError = false;
        var objItem = $(this);
        var validArr = validate(objItem, input_val, show_div_node,autoAjax);
        isError = validArr['isCheck'];
		var isAjax = validArr['isAjax'];
		var isCard = validArr['isCard'];
        if (isError && isAjax==false && isCard==false) {
            showMessage('格式正确', show_div_node, false,true);
        }
    });
    $("form").submit(function(){
        var isSubmit = true;
        $(this).find("input").each(function(){
			var input_val = $(this).val();
        	var objItem = $(this);
			var show_div_node = $(this).parents(parentTag).find('.' + showClass);
			 show_div_node.show();
			var validArr = validate(objItem, input_val, show_div_node,true);
			var isValidate = validArr['isCheck'];
			if(isValidate==false){
				isSubmit = isValidate;
			}
        });
        return isSubmit;
    });
}



/**
 * 验证属性介绍
 * 1、require，为空验证，取值 true Or false
 * 2、min或max，长度最小或最大值验证，可以只有一个属性或两个同时有
 * 3、reg,正则匹配，
 * 	  a、如果reg值是num(整数)、tel(电话或座机)、card(身份证)、chinese(中文)、email(邮箱)、qq(qq)，
 * 	     其中一种，按对应系统提供的正则表达式匹配。
 * 	  b、如果reg值是一个正则表达式，按提供的正则匹配。
 * 	  c、reg属性对应一个regMsg属性，regMsg属性可有可无。如果有，reg验证出错，就会显示regMsg内容，如果没有，出错显示系统默认提示。		  
 * 4、url,ajax远程验证属性，默认按照input框属性name名字提交到后台，后台可以根据改名字，获取input输入内容，进行验证。
 * 	  验证过后需要返回json格式数据，包括两个属性，error(1、验证错误。0、验证成功),msg（验证成功或错误的提示信息）
