Question

我需要做的是当列表项鼠标悬停改变图像（其他div）具有相同的索引时，它必须在单击时保持不变。当鼠标离开它必须是点击之前或哪个活动。我做了一些事但没有工作。

<div class="all-wrap">
    <div class="left-side">
        <ul>
            <li>Tittle 1</li>

            <li>Tittle 3</li>
            <li>Tittle 4</li>
            <li>Tittle 5</li>
        </ul>
    </div>
    <div class="right-side">
        <img src="http://blog.dominictrumfio.com/wp-content/uploads/2015/08/Lorem-Ipsum-2.jpg" class="active">

Answer 1

$(function(){
    var index = 0;
    $('.left-side ul li').hover(function() {
        $('.right-side img').eq($(this).index()).addClass("active");
        $('.right-side img').eq($(this).index()).siblings("img").removeClass("active");
    }, function() {
        $('.right-side img').eq($(this).index()).removeClass("active");
        $('.right-side img').eq(index).addClass("active");
    });

    $('.left-side ul li').click(function(){
        index = $(this).index();
        var element = $('.right-side img').eq($(this).index());
        element.addClass("active");
        element.siblings('img').removeClass("active");
    });
});

用这个替换你的jquery。你很高兴：）

请查看下面的代码段。

$(".left-side ul li").hover(function(){
  if(!$('.right-side img').eq($(this).index()).hasClass('not-remove')){
    $('.right-side img').eq($(this).index()).addClass("active");  
  }
},function(){
  if(!$('.right-side img').eq($(this).index()).hasClass('not-remove')){
    $('.right-side img').eq($(this).index()).removeClass("active");
  }
});

$('.left-side ul li').click(function() {
  $('.right-side img').eq($(this).index()).addClass("not-remove").addClass("active");
});

.all-wrap
{
    width: 100%;
    position: absolute;
    float: left;
}
.left-side
{
    width: 50%;
    float: left;
    position: relative;
}
.left-side ul li
{
    cursor: pointer;
    margin-bottom:10px;
}
.left-side ul li:hover
{
  color:red;
}
.right-side
{
    width: 50%;
    float: left;
    position: relative;
}
.right-side img
{
    width: 100%;
    float: left;
    display:none;
}
.right-side img.active
{
  display:block;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="all-wrap">
  <div class="left-side">
    <ul>
      <li>Tittle 1</li>

      <li>Tittle 3</li>
      <li>Tittle 4</li>

    </ul>
  </div>
