js实现木马轮播图效果的方法介绍

怎么用js实现木马轮播图效果呢？为了让大家更加了解js，小编给大家总结了以下内容，一起往下看吧。

首先，我们来看一下木马轮播图效果：

具体代码如下：

html部分代码：

在html部分引入的myStyle.css文件部分代码

@charset "UTF-8"; blockquote,body,button,dd,dl,dt,fieldset,form,h3,h4,h5,h6, h7, h7, hr, input, legend, li, ol, p, pre, td, textarea, th, ul{ margin:0; padding:0} body,button,input,select,textarea{ font:12px/1.5 "Microsoft YaHei", "微软雅黑", SimSun, "宋体", sans-serif; color:#666;} ol,ul{ list-style:none} a{ text-decoration:none} fieldset,img{ border:0; vertical-align:top;} a,input,button,select,textarea{ outline:none} a,button{ cursor:pointer} .wrap{ width:1200px; margin:100px auto;}.slide{ height:500px; position: relative;} .slide li{ position:absolute; left:200px; top:0} .slide li img{ width:100%} .arrow{ opacity:0;} .prev ,.next{ width:76px; height:112px; position:absolute; top:50%; margin-top:-56px; background:url(../images/prev.png) no-repeat; z-index:99;}  .next{ right:0; background-image:url(../images/next.png);}

在html部分引入的animate.js文件部分代码

/** * Created by RENPINGSHENG on 2018/4/6. */ function animate(obj,json,fn) { clearInterval(obj.timer); obj.timer = setInterval(function () {  var flag = true;  for(var k in json){   if( k == "opacity"){    var leader = getStyle(obj,k) * 100;    var target = json[k] * 100;    var step = (target - leader) /10;    step = step > 0 ? Math.ceil(step) : Math.floor(step);    leader = leader + step;    obj.style[k] = leader /100;   } else if ( k == "zIndex"){    obj.style[k] = json[k];   }else{    var leader = parseInt(getStyle(obj,k)) || 0;    var target = json[k];    var step = (target - leader) /10;    step = step >0 ? Math.ceil(step) : Math.floor(step);    leader = leader + step;    obj.style[k] = leader + "px";   }    console.log("target:" + target + "leader:" + leader + "step:" + step);   if (leader != target){    flag = false;   }  }   if (flag){   clearInterval(obj.timer);   if(fn){    fn();   }  } },15)} function getStyle(obj,attr){ if (obj.currentStyle){  return obj.currentStyle[attr]; }else{  return window.getComputedStyle(obj,null)[attr]; }}

在html部分引入的my.js文件部分代码

/** * Created by RENPINGSHENG on 2018/4/6. */  _window.onload = function () { var wrap = document.getElementById("wrap"); var slide = document.getElementById("slide"); var ul = slide.children[0]; var lis = ul.children; var arrow = document.getElementById("arrow"); var arrRight = document.getElementById("arrRight"); var arrLeft = document.getElementById("arrLeft");  var config = [  {   width:400,   top:20,   left:50,   opacity:0.2,   zIndex:2  },  {   width:600,   top:70,   left:0,   opacity:0.8,   zIndex:3  },  {   width:800,   top:100,   left:200,   opacity:1,   zIndex:4  },  {   width:600,   top:70,   left:600,   opacity:0.8,   zIndex:3  },  {   width:400,   top:20,   left:750,   opacity:0.2,   zIndex:2  } ];  wrap.onmouseover = function () {  animate(arrow,{"opacity":1}); } wrap.onmouseout = function () {  animate(arrow,{"opacity":0}); } function assign() {  for(var i = 0;i < lis.length;i++){   animate(lis[i],config[i],function(){    flag = true;   })  } }  var flag = true; assign(); arrRight.onclick = function () {  flag = false;  config.push(config.shift());  assign(); }; arrLeft.onclick = function () {  flag = false;  config.unshift(config.pop());  assign(); }}
