Question

我有以下方式设置背景图片：

#collection-5777203c893fc094ec1de004{
  background-image: url(https://static1.squarespace.com/static/57771b9e15d5dbc2f8fc084d/57771c55e3df28c63c9e687f/57771ca7440243196bc6801b/1467423990309/Gator.jpg?format=1500w);
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
}

我有一个链接，我想在悬停时触发背景图像更改，我希望它不会悬停在链接上时返回到原始图像。

我已经使用这个jquery改变了背景图像：

<script>

  jQuery('#block-5777203c893fc094ec1de005').hover(function() 
{ 
    jQuery('#collection-5777203c893fc094ec1de004').css("background-image", "url(https://static1.squarespace.com/static/57771b9e15d5dbc2f8fc084d/57771c55e3df28c63c9e687f/57771d441b631b48a1362df6/1467424076131/patagoniawater.jpg?format=750w)"); 
}); 
</script>

有人可以向我显示代码，以便在不悬停在链接上时将图像返回到原始背景图像吗？

图像也会稍微改变一下。我不确定我能做些什么来使变化更顺畅。

提前致谢。

Answer 1

jQuery hover支持两个事件：处理程序“In”（鼠标悬停）和处理程序“Out”（mouseout），因此利用它们。

并且，为方便起见，您可以使用jQuery css作为“getter”来获取原始背景图像，然后再修改它。

// Since we're using these multiple times, assign them to variables
var $link = jQuery('#block-5777203c893fc094ec1de005');
var $image = jQuery('#collection-5777203c893fc094ec1de004');
// Get the original background image
var originalBackground = $image.css('background-image');
// jQuery hover supports TWO functions: first is "mouseover", second is "mouseout"
$link.hover(
    // On mouseover, replace image
    function() { 
        $image.css("background-image", "url(https://static1.squarespace.com/static/57771b9e15d5dbc2f8fc084d/57771c55e3df28c63c9e687f/57771d441b631b48a1362df6/1467424076131/patagoniawater.jpg?format=750w)"); 
    },
    // On mouseout, put original image back
    function() {
        $image.css('background-image', originalBackground);
    }
);

您可以使用Snippet 1中演示的简单CSS :hover，或者使用片段2中演示的mouseenter and mouseleave。实际上有些东西比JS / jQ更好，这是其中之一罕见的情况。

Answer 3

HTML：

<a id="mylink" href="link" style="yourstyle" onmouseover="overStyle(this)" onmouseout="outStyle(this)">TEXT</a>

jQuery的：

function overStyle(object) 
{
  $('#mylink').css("background-image", "new image");
}

function outStyle(object) 
{
  $('#mylink').css("background-image", "old image");
}

Jquery背景图像更改链接鼠标悬停并返回mouseout
