3、js代码

var EventTips = (function(window, $) {

	function Tips() {
		this.version = "0.01";
		this.author = "";
		this.init();
	}

	Tips.prototype.init = function() {

		var tipsBox = $('<div>').addClass('event-tips-box');
		var tipsIcon = $('<div>').addClass('event-tips-icon');
		var tipsMsg = $('<div>').addClass('event-tips-msg');
		tipsBox.append(tipsIcon,tipsMsg);
		tipsFloat.append(tipsBox);
		$('body').prepend(tipsFloat);
	}

	Tips.prototype.error = function(string, time) {
		$('.event-tips-float').show();
		var time = time || 1000;
		$('.event-tips-float').find('.event-tips-icon').addClass('tips-err').removeClass('tips-success tips-wait');
		$('.event-tips-float').find('.event-tips-msg').html(string);
		var timer = setTimeout(function() {
			$('.event-tips-float').hide();
			clearTimeout(timer);
		}, time);
	}

	Tips.prototype.success = function(string, time) {
		var time = time || 1000;
		$('.event-tips-float').show();
		$('.event-tips-float').find('.event-tips-icon').addClass('tips-success').removeClass('tips-wait tips-err');

	}

	Tips.prototype.wait = function(string) {
		var that = this;
		$('.event-tips-float').show();

		$('.event-tips-float').find('.event-tips-msg').html(string);
		var timer = setTimeout(function() {

	}

	return Tips;
})(window, jQuery);
