Question

我有一个包含图像的Div列表。当我将鼠标悬停在div上时，我希望图像向上移动（我通过在悬停时改变图像css来做到这一点）。我遇到的问题是当我将鼠标悬停在一个div上时，所有div中的所有图像都在变化。相反，我希望悬停效果只发生在我悬停的div上。这是我目前的jQuery：

＆＃13;

jQuery(document).ready(function($){
  screenshotHeight = $('.l_admin-product-screenshot img').height(); 

  $('.l_admin-product').hover(function () {
    $('.l_admin-product-screenshot img').css({
      top: -screenshotHeight
    });
  },

                              function () {
    $('.l_admin-product-screenshot img').css({
      top: '0'
    });
  });

});

＆＃13;

这是我的html结构：

<div class="l_admin-products">

<div class="l_admin-product" tabindex="0">
            <input name="layes-preset-layout" id="layers-preset-layout-skizzar-homepage-1-radio" class="l_admin-hide" type="radio" value="skizzar-homepage-2">
            <label for="layers-preset-layout-skizzar-homepage-1-radio">
                <input id="layers-preset-layout-skizzar-homepage-1-title" type="hidden" value="Splash Page">

</div>

Answer 1

$('.l_admin-product').hover(function () {
  $this = $(this);

  $this.find('.l_admin-product-screenshot > img').css({
    top: -screenshotHeight
  });
},function () {
  $this.find('.l_admin-product-screenshot img').css({
  top: '0'
  });
});

尝试使用$this指向当前图像。

jQuery仅对当前元素悬停效果
