在jQuery中悬停时显示图像上的链接 [英] Show Link on image at hovering in jquery

问题描述

我使用 Bootstrap 3 和 jQuery 1.9.1 创建一个网站，其中显示个人资料图片a < li> 标记。当我在图片上方悬停时，我想显示更新图片的链接。到目前为止，我设法褪色的图像悬停，但我无法显示链接或文本悬停在图像上。这是我的代码，

I'm using Bootstrap 3 and jQuery 1.9.1 to make a website where profile picture is shown in a <li> tag. I want to show the link of "Update Image" when I'm hovering over the image. So far I've managed to fade the image on hovering but I'm unable to show a link or text on hovering over image. Here are my codes,

JQUERY

$(function () {
    $(".img-profile").hover(
        function () {
            $(this).fadeTo(200, 0.45);
        },
        function () {
            $(this).fadeTo(200, 1);
        });
});

CSS

.img-profile {
    margin-top: 10px;
    width: 200px;
    height: 250px;
}

HTML

<div class="navbar-default sidebar" role="navigation">
    <div class="sidebar-nav navbar-collapse">
        <ul class="nav" id="side-menu">
            <li>
                <img class="img-responsive img-rounded img-profile" src="myimage.png" alt="profile_pic" />
            </li>
        </ul>
    </div>
</div>

我搜索了其他来源，但没有一个工作，因为它会bug我自己的CSS风格。如何在悬停时在图像中间显示链接？需要这个帮助！谢谢。

I've searched other sources but none of them works since it'll bug my own css styles. How can I show a link at the middle of the image on hovering? Need this help badly! Thanks.

推荐答案

希望，如果你想做没有Jquery - 即使如果你想使用jquery管理它，也可以做。不是大问题

Hope, if you want to do it without Jquery - even though if you want to manage it using jquery, it can also be done.. not a big issue

.img-profile {
  margin-top: 10px;
  width: 200px;
  /* if image is bigger it will adjust according to parent width */
  height: 250px;
  display: inline-block;
}
.img-wrap {
  display: inline-block;
  position: relative;
}
.img-wrap:hover .img-profile {
  opacity: 0.5;
}
.img-wrap .hover-div {
  display: none;
  position: absolute;
  text-align: center;
  top: 50%;
  left: 0;
  right: 0;
  margin-top: -10px;
  z-index: 10;
  /* width of image container */
}
.img-wrap:hover .hover-div {
  display: inline-block;
}
