alert 替代效果smoke.js

在一些表单等需要弹窗提醒的时候，每个浏览器都有一个alert()，comfirm()函数能弹出信息，但是浏览器的自带的这种效果样式不统一，而且都固定在页面顶部；

smoke.js轻量级的JS插件，他标准化浏览器的alert(), comfirm()效果。完全是由html、css、js编写；

• 要求：CSS3支持
• 兼容性：大部分浏览器，包括IE6（没有CSS3可视化效果）
• License:MIT

使用方法：本文使用的是click事件，你也可以自定义事件触发类型；

alert()效果--smoke.alert(string, fn,obj)

string--弹出框文字内容，fn--回调函数，obj--{ok:'按钮文字',cancel:'取消按钮文字',classname:'叠加的弹窗框样式名'}

/*alert*/
	$('a[rel="demo-alert"]').on('click',function(e){
		e.preventDefault();
		smoke.alert("Wouldn't it be funny if Animal Collective was an actual<br /> collective of actual animals?", function(e){
			smoke.signal('No really...it totally would, dude.<br />I mean, think about it.');
		},{
			ok: "Yep",	//确定按钮文字
			cancel: "Nope",	//取消按钮文字
			classname: "custom-class"	//弹出框样式
		});
	});

confirm效果--smoke.confirm(string,fn,obj)

/*confirm*/
	$('a[rel="demo-confirm"]').on('click',function(e){
		e.preventDefault();
		smoke.confirm("Slippery breath inside<br /> banjo melted. Runny smoky. ",function(e){
			if (e){	//确定按钮回调
				smoke.signal('Perfect. We\'ll be in touch.');	//点击按钮响应lightbox效果，基本上看不见，因为没有设置延迟时间 smoke.signal()会闪一下就消失了。
			}else{	//取消按钮回调
				smoke.signal('Please...me so sorry. You look good in dress, you look better on my floor.');
			}
		}, {
			reverseButtons: true,	//确定和取消按钮哪个在前；true ok按钮在前，false cancel按钮在前
			classname: "custom-class",
			ok: "AGREE",	//确定文字
			cancel: "DISAGREE"	//取消文字
		});
	});

quiz效果--smoke.quiz(string, fn, obj)，多按钮（最多三个）

/*quiz*/
	$('a[rel="demo-quiz"]').on('click',function(e){
		e.preventDefault();

		smoke.quiz('Which of these things<br /> is the worst thing?', function (e){
			if (e == 'DISCO'){　　//点击每个按钮的触发的效果
				smoke.signal('nope. it\'s funk.');
			}
			if (e == 'REGGAE'){
				smoke.signal('nope. it\'s disco.');

			}
			if (e == 'FUNK'){
				smoke.signal('nope. it\'s reggae.');
			}
		},
			{
				button_1	:	"DISCO", 	//多按钮（最多三个）
				button_2	: "REGGAE",
				button_3	: "FUNK",
				button_cancel: "NONE OF THEM"	//取消按钮
			}
		);
	});

signal，设置弹出框，没有按钮，可以设置弹框消失的延迟时间

/*signal*/
	$('a[rel="demo-signal"]').on('click',function(e){
		e.preventDefault();
		smoke.signal('Congratulations! You have just one a free iPod Touch!', function(){}, {duration: 5000, classname: "custom-class"});　　//duration:5000设置延迟时间为5000毫秒
	});

prompt，带有输出框的alert效果

/*prompt*/
	$('a[rel="demo-prompt"]').on('click',function(e){
		e.preventDefault();
		o.prompt_demo(1);
	});
var o={
	prompt_demo: function(ver){
	　　var q = 'What\'s in the bag?';　　//设置提示文字，这个是用来遵循文本框的内容约束规则。文本框如果是必填的话就会需要，在用户移除文本框的时候就会触发提示文字。
	　　if (ver == 2){
	　　　　q = 'No no, you HAVE to answer.<br /> What\'s in the bag?';
	　　}
	　　smoke.prompt(q, function(e){
	　　　　if (e){　　//ok按钮的效果
	　　　　　　smoke.signal('You have no idea how badly<br /> I need a bag of '+e+'. <br /><br /> Give it to me. Right now.<br /><br />');
	　　　　}else{　　//cancel按钮效果
	　　　　　　o.prompt_demo(2);
	　　　　}
	}, {
		reverseButtons: true,　　//翻转按钮顺序
		value: 'hammers',	//文本框里的默认内容
		ok: 'Have a look',	//确定按钮文字
		cancel: 'None of your business'	//取消按钮文字
	});
　　}
}

鼠标移除文本框后或单击cancel按钮
