概述

HTML代码：

复制代码代码如下:

 
<!DOCTYPE html> 
<html> 
<head> 
<title></title> 
<style> 
*{padding:0;margin:0} 
ul{list-style:none} 
.slider-focus{width:670px;height:240px;overflow:hidden;position:relative;margin:100px auto}

<script src="slider.js"></script>

</html> 

Javasscript 代码：

复制代码代码如下:

 
function Sliderfocus(options){ 
this.focus = options.focus; 
this.slider = options.slider; 
this.btns = options.btns; 
this.width = options.width; 
this.speed = options.speed || 800; 
this.curIndex = options.curIndex || 0; 
this.size = this.btns.size(); 
this.init(); 
this.timeout = null; 
this.stopTemp = 1 ; 
} 

Sliderfocus.prototype = { 
init:function(){ 
this.auto(); 
this.bind(); 
}, 
play:function(){ 
this.slider.stop().animate({ 
left:-this.curIndex * this.width 
},this.speed); 
}, 
auto:function(){ 
var that = this; 
this.timeout = setTimeout(function(){ 
if(that.stopTemp == 0){ 
return; 
}else{ 
that.next(); 
that.auto(); 
} 
},4000); 
}, 
prev:function(){ 
this.curIndex = --this.curIndex<0? this.size-1 : this.curIndex; 
this.play(); 
}, 
next:function(){ 
this.curIndex = ++this.curIndex>this.size-1? 0 : this.curIndex; 
console.log(this.curIndex) 
this.play(); 
}, 
stop:function(){ 
this.stopTemp = 0; 
}, 
bind:function(){ 
var that = this; 
this.focus.bind("mouseover",function(){ 
that.stop(); 
}).bind("mouseout",function(){ 
that.stopTemp = 1; 
//that.auto(); 
}); 
this.letsgo(); 
}, 
letsgo:function(){ 
var that = this; 
this.btns.bind("click",function(){ 
var index = $(this).index(); 
that.curIndex = index; 
that.play(); 

}); 
} 
}; 

new Sliderfocus({ 
focus:$(".slider-focus"), 
slider:$(".slider-focus .slider"), 
btns:$(".btns li"), 
width:670 
});
