js利用apply(), Math object, js数组,对象完全智能验证

注:主要功能就是监听你的错误,哪里有错误就滑到哪里去提示,并且速度可设置,超级人性化,但是错误绑定是必须有id属性的,id作为你验证的唯一身份证, 因为在项目中用到了所以临时挑拣出来的代码,比如监听事件哪里应当封装,加上特殊验证类等,时间问题回头再弄,以下如有问题请留言 :

列出两个类,演示就不列了因为实在样式太不好看了!


/**
*error store class
*/
var Errortop = {
	setErrorTop:function (_this){   
		var height = jQuery(_this).offset().top;
		validateExam.put(height, height, jQuery(_this).attr('id'));
	},

	getErrorTopTip:function (min,time){ 
			if(validateExam.keys.length > 0){
		var maxhight = Math.max.apply(null,validateExam.keys); 
				jQuery('html,body').animate({scrollTop:maxhight-min},time);   // alert(validateExam.obj[maxhight]);
				jQuery("#"+validateExam.obj[maxhight]).focus().css('borderColor', 'red');
			}
	},

	remove:function(id){
		validateExam.remove(id);
	}
}
