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；
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；
<body> <a href="#" rel="demo-alert">alert</a> <a href="#" rel="demo-confirm">confirm</a> <a href="#" rel="demo-prompt">prompt</a> <a href="#" rel="demo-quiz">quiz</a> <a href="#" rel="demo-signal">signal</a> </body>
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;

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
