alert 替代效果smoke.js_html/css_WEB-ITnose

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	confirm	prompt	quiz	signal

样式：

.smoke-base {		position: fixed;		top: 0;		left: 0;		bottom: 0;		right: 0;		visibility: hidden;		opacity: 0;	}	.smoke-base.smoke-visible {		opacity: 1;		visibility: visible;	}	.smokebg {		position: fixed;		top: 0;		left: 0;		bottom: 0;		right: 0;	}	.smoke-base .dialog {	  position: absolute;	}	.dialog-prompt {	  margin-top: 15px;	  text-align: center;	}	.dialog-buttons {	  margin: 20px 0 5px 0	}	.smoke {	  font-family: Menlo, 'Andale Mono', monospace;	  text-align: center;	  font-size: 22px;	  line-height: 150%;	}	.dialog-buttons button {	  display: inline-block;	  vertical-align: baseline;	  cursor: pointer;	  font-family: Menlo, 'Andale Mono', monospace;	  font-style: normal;	  text-decoration: none;	  border: 0;	  outline: 0;	  margin: 0 5px;	  -webkit-background-clip: padding-box;	  font-size: 13px;	  line-height: 13px;	  font-weight: normal;	  padding: 9px 12px;	}	.dialog-prompt input {	  margin: 0;	  border: 0;	  font-family: sans-serif;	  outline: none;	  font-family: Menlo, 'Andale Mono', monospace;	  border: 1px solid #aaa;	  width: 75%;	  display: inline-block;	  background-color: transparent;	  font-size: 16px;	  padding: 8px;	}	.smoke-base {	  background: rgba(0,0,0,.3);	  filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#90000000,endColorstr=#900000000);	}	.smoke-base .dialog {		top: 25%;		width: 30%;		left: 50%;		margin-left: -20%;	}	.smoke-base .dialog-inner {	  padding: 15px;	  color:#202020;	}	.smoke {	  background-color: rgba(255,255,255,0.95);	  filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#ffffff,endColorstr=#ffffff);		box-shadow: 0 2px 8px #000;	}	.dialog-buttons button {	  background-color: rgba(0,0,0,.85);	  filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#222222,endColorstr=#222222);	  border-radius: 0;	  color: #fff;	}	button.cancel {	  background-color: rgba(0,0,0,.40);	  filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#444444,endColorstr=#444444);	}	.queue{		display:none;	}

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
 collective of actual animals?", function(e){			smoke.signal('No really...it totally would, dude.
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
 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
 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.
 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
 I need a bag of '+e+'. 

 Give it to me. Right now.

');	　　　　}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
