Question

我在一个页面中使用了两个进度条carousel。第一个旋转木马会破坏第二个进度条。

这是我的第一个旋转木马：

<div id="owl-demo" class="owl-carousel owl-theme">
    <div class="item"><img src="images/fullimage1.jpg" alt="The Last of us"></div>
    <div class="item"><img src="images/fullimage2.jpg" alt="GTA V"></div>
    <div class="item"><img src="images/fullimage3.jpg" alt="Mirror Edge"></div>          
</div>

第二个：

<div id="owl-demo2" class="owl-carousel owl-theme">
    <div class="item"><img src="images/fullimage1.jpg" alt="The Last of us"></div>
    <div class="item"><img src="images/fullimage2.jpg" alt="GTA V"></div>
    <div class="item"><img src="images/fullimage3.jpg" alt="Mirror Edge"></div>          
</div>

我已将id更改为owl-demo2。这是我的css文件：

#owl-demo .item img{display: block; width: 100%; height: auto;}
#bar{  width: 0%;  max-width: 100%;  height: 4px;  background: #990000;}
#progressBar{  width: 100%;  background: #8A6D3B;}
#owl-demo2 .item img{display: block; width: 100%; height: auto;}

这是js文件

  var time = 7; // time in seconds

  var $progressBar,
      $bar, 
      $elem, 
      isPause, 
      tick,
      percentTime;

    //Init the carousel
    $("#owl-demo").owlCarousel({
      slideSpeed : 500,
      paginationSpeed : 500,
      singleItem : true,
      afterInit : progressBar,
      afterMove : moved,
      startDragging : pauseOnDragging
    });

    $("#owl-demo2").owlCarousel({
      slideSpeed : 500,
      paginationSpeed : 500,
      singleItem : true,
      afterInit : progressBar,
      afterMove : moved,
      startDragging : pauseOnDragging
    });

    //Init progressBar where elem is $("#owl-demo")
    function progressBar(elem){
      $elem = elem;
      //build progress bar elements
      buildProgressBar();
      //start counting
      start();
    }

    //create div#progressBar and div#bar then prepend to $("#owl-demo")
    function buildProgressBar(){
      $progressBar = $("<div>",{
        id:"progressBar"
      });
      $bar = $("<div>",{
        id:"bar"
      });
      $progressBar.append($bar).prependTo($elem);
    }

    function start() {
      //reset timer
      percentTime = 0;
      isPause = false;
      //run interval every 0.01 second
      tick = setInterval(interval, 10);
    };

    function interval() {
      if(isPause === false){
        percentTime += 1 / time;
        $bar.css({
           width: percentTime+"%"
         });
        //if percentTime is equal or greater than 100
        if(percentTime >= 100){
          //slide to next item 
          $elem.trigger('owl.next')
        }
      }
    }

    //pause while dragging 
    function pauseOnDragging(){
      isPause = true;
    }

    //moved callback
    function moved(){
      //clear interval
      clearTimeout(tick);
      //start again
      start();
    }

我的第一个问题是，我哪里弄错了？第二个问题是，是否可以将进度条从上到下？提前谢谢

之所以发生这种情况，是因为id应该是唯一的，并且您为两个进度条提供相同的ID。

所以按类更改ids，例如：

function buildProgressBar(){
    $progressBar = $("<div>",{
        class:"progressBar"
    });
    $bar = $("<div>",{
       class:"bar"
    });
    $progressBar.append($bar).prependTo($elem);
}

然后在bar函数中使用类interval()来更新此类的所有元素：

$('.bar').css({
   width: percentTime+"%"
});

还将css规则从id更改为类：

.bar{  width: 0%;  max-width: 100%;  height: 4px;  background: #990000;}
.progressBar{  width: 100%;  background: #8A6D3B;}

最后替换：{/ p>中的$elem

$elem.trigger('owl.next');

按$(".owl-carousel")，owl.next将适用于两个轮播：

$(".owl-carousel").trigger('owl.next');

希望这有帮助。
