php - 旋转木马显示完美，但不会滑动

Question

帮我调试 carousel 的 php 代码，它不会滑走，我错过了什么？我希望它在页面加载时自动滑动，不要介意当我单击指示器时它不会滑动。

echo '<div id="myCarousel" class="carousel slide" data-ride="carousel">';
    echo '
    <ol class="carousel-indicators">
    <li data-target="#myCarousel" data-slide-to="0" class="active"></li>
    <li data-target="#myCarousel" data-slide-to="1"></li>
    </ol>';

    echo '<div class="carousel-inner" role="listbox">';

    echo '<div class="item active">';
    echo '<div class="jumbotron" style="border:solid 3px;height:500px;margin-top:20px">';   
    echo '<div class="containeractive  col-md-6"
         style="height:400px;border:solid 2px; margin: 0px 50px 10px 20px;
         background-image:url('.$row['image'].');background-repeat:no-repeat;background-size:contain; background-position:center"></div>';
    echo '<div class="container col-md-5" style="height:85px;border:solid 3px;margin-bottom:30px">'.$row['name'].'</div>';
    echo '<div class="container col-md-5" style="height: 285px; border:solid 3px;">'.$row['description'].'</div>';
    echo '</div>';
    echo '</div>';

    mysqli_data_seek($result,1);
    $row2 = mysqli_fetch_array ($result);

    echo '<div class="item">';
    echo '<div class="jumbotron" style="border:solid 3px;height:500px;margin-top:20px">';   
    echo '<div class="container col-md-6"
         style="height:400px;border:solid 2px; margin: 0px 50px 10px 20px;
         background-image:url('.$row2['image'].');background-repeat:no-repeat;background-size:contain; background-position:center"></div>';
    echo '<div class="container col-md-5" style="height:85px;border:solid 3px;margin-bottom:30px">'.$row2['name'].'</div>';
    echo '<div class="container col-md-5" style="height: 285px; border:solid 3px;">'.$row2['description'].'</div>';
    echo '</div>';
    echo '</div>';

    echo '</div>';
    echo '</div>';

你没有添加 bootstrap 的 javascript。只需将其添加到正文部分的末尾

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
