    2. JS实现

    包含的文件

    HTML代码:

        

     <header class="jumbotron">
                 <img src="17.png" class="image" id="imageId">
                 <p class="lead">第一张</p>

    JS代码:

    $(document).ready(function(){
       var imageArray = new Array();
       var imageNumber = 1;
       imageArray = ["17.png","19.png","20.png",];
       $("#next").click(function(){
          imageNumber++;
          if(imageNumber == 4){
             imageNumber = 1;
          }
          switch (imageNumber)
          {
          case 1 :
             $("#imageId").attr("src",imageArray[0]);
              $(".lead").html("我是第一张")
             break;
          case 2 :
             $("#imageId").attr("src",imageArray[1]);
              $(".lead").html("我是第二张")
             break;
          case 3 :
             $("#imageId").attr("src",imageArray[2]);
              $(".lead").html("我是第三张")
