復(fù)制代碼代碼如下:

<body>

        <a href="javascript:;">向左走</a>

        <a href="javascript:;">向右走</a>

        <div id="div1">

            <ul>

                <li>

                    <img src="img/無(wú)縫滾動(dòng)/1.jpg" />

                </li>

                <li>

                    <img src="img/無(wú)縫滾動(dòng)/2.jpg" />

                </li>

                <li>

                    <img src="img/無(wú)縫滾動(dòng)/3.jpg" />

                </li>

                <li>

                    <img src="img/無(wú)縫滾動(dòng)/4.jpg" />

                </li>

            </ul>

        </div>

    </body>

以上是一個(gè)簡(jiǎn)單的布局，下面是主要的Javascript 代碼

復(fù)制代碼代碼如下:

<script type="text/javascript">

            window.onload = function() {

                var oDiv = document.getElementById("div1");

                var oUl = oDiv.getElementsByTagName('ul')[0];

                var aLi = oUl.getElementsByTagName('li');

                var speed = 2;            

                oUl.innerHTML += oUl.innerHTML;

                oUl.style.width = aLi[0].offsetWidth * aLi.length + 'px';

                function move() {

                    if (oUl.offsetLeft < -oUl.offsetWidth / 2) {

                        oUl.style.left = '0';

                    }

                    if (oUl.offsetLeft > 0) {

                        oUl.style.left = -oUl.offsetWidth / 2 + 'px';

                    }

                    oUl.style.left = oUl.offsetLeft + speed + 'px';

                }

                var timer = setInterval(move, 30);

                oDiv.onmouseover = function() {

                    clearInterval(timer);

                };

                oDiv.onmouseout = function() {

                    timer = setInterval(move, 30);

                };

                document.getElementsByTagName('a')[0].onclick = function() {

                    speed = -2;

                };

                document.getElementsByTagName('a')[1].onclick = function() {

                    speed = 2;

                };

            }

        </script>
