The example in this article describes the jQuery simple custom image carousel plug-in and its usage. Share it with everyone for your reference, the details are as follows:

I often use other people’s plug-ins, now I write one myself to commemorate it.

jQuery.banner.js:

/*
* banner 0.1
* 使用banner 实现图片定时切换 鼠标经过停止动画
* 鼠标离开，继续动画
*/
;(function($){
  $.fn.banner =function(options){
    //各种属性和参数
    var defaults ={
       picWidth:"1000",
      picHeight:"300",
      speed:"1500"
    };
    var totalW = 0;  //保存总的动画宽度
    var timer = null; //保存定时器
    var current = 0; //保存当前动画到第N张图，下次从这里开始
    var totalNum = 0; //保存总的图数
    var Dsqtime = 0; //定义定时器时间 【外传参数】
    var Dhtime = 0;  //定义动画时间
    var count = 0 ;
    //合并多个对象为一个，即有新参数 用新的，否则用默认的
    var options = $.extend(defaults, options);
    this.each(function(){
      //实现代码
      var __this = $(this);
      Dsqtime = options.speed;
      Dhtime = Dsqtime/3;
      //初始化
      init(__this);
      //调用动画
      show(__this, options.picWidth,current);
      //鼠标经过时事件
      __this.find(&#39;ul li&#39;).bind(&#39;mouseover&#39;,function(){
        window.clearInterval(timer); //清除定时器
      });
      __this.find(&#39;ul li&#39;).bind(&#39;mouseout&#39;,function(){
        show(__this, options.picWidth,current);
         //接着上一次动画轮播
      });
    });
    //初始化 设定父容器宽度
    function init(obj){
      obj.find(&#39;ul li&#39;).each(function(){
         totalW += $(this).width();
         totalNum++;
       });
      obj.find(&#39;ul&#39;).width(totalW);
    }
    //开始动画显示
    function show(obj, width, current){
      timer = setInterval(function(){
      obj.find(&#39;ul&#39;).animate({&#39;margin-left&#39;:&#39;-&#39;+count*width+&#39;px&#39;},
         Dhtime);
          current = count;
          count++;
          if(count == totalNum){
           count =0;
          }
       }, Dsqtime);
    }
  };
})(jQuery);
