当点击不同的li时,jQuery显示li

我有两个列表 - 第一个列表有名称,图像和描述较大,第二个列表是小缩略图列表。单击缩略图时,我需要相应的li,只显示较大的图像和文本。因此,如果单击John Doe的缩略图,我需要显示较大的John Doe图像和文本,并确保隐藏较大的Bob Doe和Tom Doe图片和文本。我还想在页面加载时显示第一个更大的图像和描述。到目前为止,这是我的HTML和jQuery - 谢谢!

  <div id="bios">
      <ul>
        <li>
            <img src="../img/jd.jpg" alt="John Doe">
            <br>
            <span class = "name">John Doe</span>
            <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc vulputate diam ut porta pharetra. Nunc egestas ac turpis nec tempor.</p>
        </li>

        <li>
            <img src="../img/bd.png" alt="Bob Doe">
            <br>
            <span class = "name">Bob Doe</span>
            <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc vulputate diam ut porta pharetra. Nunc egestas ac turpis nec tempor.</p>
        </li>

        <li>
            <img src= "../img/td.png" alt="Tom Doe">
            <br>    
            <span class = "name">Tom Doe</span>
            <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc vulputate diam ut porta pharetra. Nunc egestas ac turpis nec tempor.</p>
        </li>

       </ul>    
</div>
    <div id = "thumb">
      <ul>  
        <li>

            <img src="../img/jdthumb.png" alt="John Doe">
            <br>
            John Doe        
        </li>


        <li>

            <img src="../img/bdthumb.png" alt="Bob Doe">
            <br>
            Bob Doe

        </li>

        <li>    

            <img src= "../img/tdthumb.png" alt="Tom Doe">
            <br>
            Tom Doe

        </li>   

    </ul>
</div>

jQuery的:

  $("#bios li").first().css( "display", "block" );

  $("#thumb li").on('click', function() {
      $( "#bios li" ).css( "display", "block");
      $(this).siblings('li').slideToggle();

  });

试试这个:

css

#bios > ul > li{
    display: none;
}
#bios > ul > li:first-child{
    display: block;
}

javascript

$(function(){
    $('#thumb ul li').click(function(){
        var index = $(this).index();
        $('#bios ul li').hide();
        $('#bios ul li').eq(index).show();
    });
});

这是你的jsfiddle

Barmar的答案很棒,只要您愿意始终在缩略图和图像之间保持一对一的对应关系,并将它们保持在相同的标记顺序中。如果没有,我建议您配对ID,例如,

<li id="img-john">  <!-- or use `img-1`, `img-2`, etc. -->
    <img src="../img/jd.jpg" alt="John Doe">
    <!-- ... -->
</li>
<li id="img-bob">
    <img src="../img/bd.jpg" alt="Bob Doe">
    <!-- ... -->
</li> <!- ... -->

<!-- ... -->

<li id="thumb-john">
    <img src="../img/jdthumb.jpg" alt="John Doe">
    <!-- ... -->
</li>
<li id="thumb-bob">
    <img src="../img/bdthumb.jpg" alt="Bob Doe">
    <!-- ... -->
</li> <!- ... -->

然后你可以做这样的事情(未经测试):

$("#thumb li").click(function() {
    var id = this.id.replace("img", "thumb");
    $("#bios li").hide();
    $("#" + id).show();
    $(this).siblings("li").slideToggle();
});
