我正在尝试使用jquery在href图像上添加类别标签。现在我有以下小提琴:https://jsfiddle.net/Eddiebouncer/43x6L2bj/jQuery检查链接中的类别并添加标签。但这也以文本链接为目标(这将在最后得到预期)。
如何仅定位带有图像的href来覆盖标签?
问候,爱德'
HTML
<div style="padding:20px;margin-top:40px;">
Example with 2 images with category A and B. Script generates a category-label accordingly.
</div>
<div class="relative-container">
<a href="something/category-A/#"><img src="https://placehold.it/300x150" /></a>
</div>
<div class="relative-container">
<a href="something/category-B/#"><img src="https://placehold.it/300x150" /></a>
</div>
<div style="padding:20px;">
Here a text link - but this shouldn't be targeted: <a href="something/category-A/#">read more</a>
</div>
JS
$(document).ready(function() {
$('a[href*="category-A"]').append('<div id="overlay-A">category A</div>');
$('a[href*="category-B"]').append('<div id="overlay-B">category B</div>');
});
CSS
.relative-container {
position: relative;
}
#overlay-A,
#overlay-B {
display: inline block;
position: absolute;
top: 0;
left: 0;
padding: 12px;
color: #fff;
}
#overlay-A {
background: rgba(0, 0, 120, 0.75);
}
#overlay-B {
background: rgba(0, 120, 0, 0.75);
}
容易,使用.relative-container
类来区分这两个
$(document).ready(function() {
$('.relative-container a[href*="category-A"]').append('<div id="overlay-A">category A</div>');
$('.relative-container a[href*="category-B"]').append('<div id="overlay-B">category B</div>');
});
或测试链接是否有图像
$('.relative-container a[href*="category-A"]').each(function() {
if($(this).has('img')) {
$(this).append('<div id="overlay-B">category B</div>');
}
})
