在 img 内悬停时显示标题标签 [英] Show title tag on hover inside img

问题描述

我需要在 img 中显示 img 的 Title 标签.

像这个例子 http://jsfiddle.net/51csqs0b/

.image {位置:相对；宽度:200px；高度:200px；}.image img {宽度:100%；垂直对齐:顶部；}.image:after, .image:before {位置:绝对；不透明度:0;过渡:全0.5s；-webkit-transition:全部为 0.5s；}.图像:在{之后内容:'\A';宽度:100%；高度:100%；顶部:0;左:0;背景:RGBA(0,0,0,0.6)；}.图像:之前{内容:属性(数据内容)；宽度:100%；颜色:#fff;z-索引:1；底部:0;填充:4px 10px;文字对齐:居中；背景:红色；box-sizing:border-box;-moz-box-sizing:border-box;}.image:hover:after, .image:hover:before {不透明度:1；}

<img src="http://i.stack.imgur.com/Sjsbh.jpg" alt=""/>
<小时><div data-content="这里有不同的标题..." class="image"><img src="http://i.stack.imgur.com/Sjsbh.jpg" alt=""/>

但我不想在 img 之前使用 div.

<a href="#"><img class="" title="TITLE NEED SHOW ON HOVER" src=""/></a>

有可能出现吗?谢谢

解决方案

我能做的只有这些:

将 .image 类添加到 a

<a class="image" href="#"><img src="http://i.stack.imgur.com/Sjsbh.jpg" class="" title="标题需要在悬停时显示" src=""/></a>

在css中用title替换data-content:

.image:before {内容:属性(标题)；宽度:100%；颜色:#fff;z-索引:1；底部:0;填充:4px 10px;文本对齐:居中；背景:红色；box-sizing:border-box;-moz-box-sizing:border-box;}

最后，添加这个 jQuery 代码:

$("a.image").each(function(){$(this).attr('title',$(this).find("img").attr('title'))});

自己运行此处:

Hi I need show a Title tag of img inside img.

Like this example http://jsfiddle.net/51csqs0b/

.image {
    position:relative;
    width:200px;
    height:200px;
}
.image img {
    width:100%;
    vertical-align:top;
}
.image:after, .image:before {
    position:absolute;
    opacity:0;
    transition: all 0.5s;
    -webkit-transition: all 0.5s;
}
.image:after {
    content:'\A';
    width:100%; height:100%;
    top:0; left:0;
    background:rgba(0,0,0,0.6);
}
.image:before {
    content: attr(data-content);
    width:100%;
    color:#fff;
    z-index:1;
    bottom:0;
    padding:4px 10px;
    text-align:center;
    background:red;
    box-sizing:border-box;
    -moz-box-sizing:border-box;
}
.image:hover:after, .image:hover:before {
    opacity:1;
}

<div data-content="Here is a caption" class="image">
    <img src="http://i.stack.imgur.com/Sjsbh.jpg" alt="" />
</div>

<hr>
    
<div data-content="Different caption here..." class="image">
    <img src="http://i.stack.imgur.com/Sjsbh.jpg" alt="" />
</div>

But i don't want use a div before img.

<a href="#"><img class="" title="TITLE NEED SHOW ON HOVER" src=""/></a>

It's possible to show up? Thanks

解决方案

This is all thing I can do:

add .image class to a

<a class="image" href="#"><img src="http://i.stack.imgur.com/Sjsbh.jpg" class="" title="TITLE NEED SHOW ON HOVER" src=""/></a>

replace data-content with title in css:

.image:before {
    content: attr(title);
    width:100%;
    color:#fff;
    z-index:1;
    bottom:0;
    padding:4px 10px;
    text-align:center;
    background:red;
    box-sizing:border-box;
    -moz-box-sizing:border-box;
}

finally, add this jQuery code:

$("a.image").each(function(){$(this).attr('title',$(this).find("img").attr('title'))});
