标签: javascript css image html overlay

当用户用鼠标悬停该图像时,我需要创建一个显示在我拇指上的删除按钮,其链接显示为从收藏夹中移除?

任何人都知道如何实现这一目标?

我想要的一个例子是你在视频大拇指上找到的youtube快速列表按钮。

当您将鼠标悬停在缩略图上时会显示图标,当您将图标悬停在其上时,它将变为悬停图标。

.image-thumb, .image-thumb img {
  position:relative;
  width:60px;
  height:50px;
}
.image-fav {
  display:none;
  position:absolute;
  bottom:0;
  left:0;
  width:15px;
  height:15px;
  background-image:url(normal_plus.png);
}
.image-thumb:hover .image-fav {
  display:block;
}
.image-fav:hover {
  background-image:url(hover_plus.png);
}

<div class="image-thumb">
  <img src="thumb.jpg" />
  <a href="#" class="image-fav"></a>
</div>

Booya!

Daniel Vassallo's原始答案修改:

CSS:

.image-thumb { 
    position: relative; 
    width: 100px;
    height: 100px; 
    /* apply background-image url inline on the element since it is part of the content */
    background: transparent url() no-repeat center center;
}

.image-thumb a { 
    display: none;
    position: absolute; 
    top: 80px;  /* position in bottom right corner, assuming image is 16x16 */
    left: 84px; 
    width: 16px; 
    height: 16px; 
    background: transparent url(remove_button.gif) no-repeat 0 0;
}   

.image-thumb:hover a { 
    display: block;
}

HTML(假设它已生成):

<div class="image-thumb" id="some-unique-thumb-id-1" style="background-image: url(some/image-1.ext)">
    <a href="#"></a>
</div>
<div class="image-thumb" id="some-unique-thumb-id-2" style="background-image: url(some/image-2.ext)">
    <a href="#"></a>
</div>
....
<div class="image-thumb" id="some-unique-thumb-id-n" style="background-image: url(some/image-n.ext)">
    <a href="#"></a>
</div>

JavaScript的:

$(function() {
    $(".image-thumb a").click(function(e) {
        e.preventDefault();
        var imageId = $(this).parent().attr("id");
        // remove image based on ID.
    });
});

编辑:简化了HTML。

您可以使用以下CSS样式的<div>来实现纯CSS:

<强> CSS:

.image-thumb { 
    position: relative; 

    width:  100px;
    height: 100px; 

    background-image: url(image_thumb.jpg); 
}

.image-fav { 
    position: absolute; 

    top:    0px; 
    left:   0px; 
    width:  20px;
    height: 20px;

    background-image: url(fav_icon.png); 
    background-position: bottom left; 

    display: none;
}   

.image-fav:hover {
    display: block;
}

<强> HTML:

<div class="image-thumb">
    <a class="image-fav" href="javascript:removeFromFav();"></a>
</div>

<div id = "thumbImg">
     <img src="thumb.png" onMouseOver="overlayRemove();" 
       onMouseOut="hideRemove();" />
     <img id='removeImg' src='remove.png' 
     style='position:relative;left:0px;top:0px;z-index:2;display:none' />
</div>

JavaScript的:

function overlayPic(){
   $('removeImg').show();
}
function hideRemove(){
   $('removeImg').fadeOut();
}
