Question

如何使此滑块自动播放？

以下是答案：

    <div class="slideshow"><ul> 
          <li><img src="lemons/1.jpg" alt="lemon" /></li>
          <li><img src="lemons/2.jpg" alt="lemon tea" /></li>
          <li><img src="lemons/3.jpg" alt="splashing lemon" /></li>
    </ul></div> 

    <script type="text/javascript">
        $(window).load(function () {
            // start the slideshow
            $('.slideshow').blinds();

        var i = 0;
        var j = 4; // this is hardcorded, one more than total images  
                   // if you have a way of making j dynamic, please share
        setInterval( function(){
            if (i == j)
                {
                    i = 1;
                    $('.slideshow').blinds_change(i);
                    i++;                        
                } else {
                    $('.slideshow').blinds_change(i);
                    i++;                        
                }
        } , 3000 );
        })
    </script>

这是原始脚本的摘录（使用在IE 8,7,6等中工作的jQueryBlinds：http://www.littlewebthings.com/projects/blinds/）：

    <div class="slideshow"><ul> 
          <li><img src="lemons/1.jpg" alt="lemon" /></li>
          <li><img src="lemons/2.jpg" alt="lemon tea" /></li>
          <li><img src="lemons/3.jpg" alt="splashing lemon" /></li>
    </ul></div> 

    <!-- change image links -->
    <a href="#" class="change_link" onclick="$('.slideshow').blinds_change(0)">1</a>
    <a href="#" class="change_link" onclick="$('.slideshow').blinds_change(1)">2</a>
    <a href="#" class="change_link" onclick="$('.slideshow').blinds_change(2)">3</a>

    <script type="text/javascript">
        $(window).load(function () {
            // start the slideshow
            $('.slideshow').blinds();
        })
    </script>
