JS对img进行操作

   <script type="text/javascript">         var i = 1; var n;         function showImg() {

            if (document.getElementById('img').getAttribute("src") == "images/1.jpg") {                 document.getElementById('img').setAttribute("src","images/2.jpg");             }             else {                  document.getElementById('img').setAttribute("src","images/1.jpg");             }         }

        function showImg1() {             document.getElementById('img').setAttribute("src", "images/" + i + ".jpg"); i++;             if (i > 10)             {                 i = 1;             }         }

        function show() {           n=setInterval(showImg1, 500);         }

        function show1() {             clearInterval(n);         }     </script>

</head> <body>     <img id="img" alt="" src="images/1.jpg" width="200" height="200" />     <input id="Button1" type="button" value="换图片" onclick="showImg()" />     <input id="Button2" type="button" value="切图" onclick="showImg1()" />     <input id="Button3" type="button" value="轮换" onclick="show()" />         <input id="Button4" type="button" value="停止轮换" onclick="show1()" />

</body> </html>
