问题描述

我正在尝试将此缩略图悬停字幕插件用于引导程序.

解决方案

您需要在图像上方放置另一个 div 并根据您的需要设置样式.

然后根据 Bootstraps 滑动等添加 hide() 或 show()

FIDDLE

HTML:

<li class="span3"><div 类="缩略图"><div 类="标题"><h4>字幕标题</h4><p>Lorem ipsum dolor sit amet，consectetur adipisicing elit，sed do eiusmod tempor incididunt.</p><p><a href="#" class="btn btn-inverse" rel="tooltip" title="Preview"><i class="icon-eye-open"></i></a><a href="#" rel="tooltip" title="访问网站" class="btn btn-inverse"><i class="icon-share"></i></a></p></div><div class="caption-btm">Lorem ipsum dolor sit amet, consectetur adipisicing eli...</div><img src="http://placehold.it/600x400" alt="ALT NAME"></div><h4>项目名称</h4></li>

CSS:

.caption-btm{背景:rgba(0,0,0,0.6)；宽度:100%；高度:30px；位置:绝对；底部:4px；颜色:#fff;}

JQuery:

$('#hover-cap-4col .thumbnail').hover(功能() {$(this).find('.caption').slideDown(250);$('.caption-btm').hide(100);},功能() {$(this).find('.caption').slideUp(250);$('.caption-btm').show(450);});

编辑

上面的 Jquery 将显示和隐藏每个 .caption-btm.

但这会隐藏它被悬停的特定的:

FIDDLE

jquery:

 $('#hover-img .thumbnail').hover(功能 () {$(this).find('.caption').slideDown(250);$(this).find('.caption-btm').hide(250);},功能 () {$(this).find('.caption').slideUp(250);$(this).find('.caption-btm').show(250);});

I am trying to use this thumbnail hover caption plugin for bootstrap.

http://sevenx.de/demo/bootstrap/thumbnail-hover-caption.html

This is the code.

<div class="thumbnail">
                <div class="caption" style="display: none;">
                    <h4>Caption Title</h4>
                    <p><a href="#" class="btn btn-inverse" rel="tooltip" title="" data-original-title="Preview"><i class="icon-eye-open"></i></a> <a href="#" rel="tooltip" title="" class="btn btn-inverse" data-original-title="Visit Website"><i class="icon-share"></i></a></p>
                </div>
                <img src="http://placehold.it/600x400" alt="ALT NAME">
              </div>

In this page, there is a part 'SlideIn/Out'.

When you hover on a thumbnail normally it slides in or out. This is what I want.

However, what I also need is when my cursor is not hover on thumbnail, there should be small caption at the bottom which I will write there a tagline.

So basically, default position will be small caption, when my mouse is over thumbnail it will slide in.

This is an exact example what I need. It can be viewed http://www.usatoday.com/news/

NO HOVER

HOVER

This is the jsfiddle page http://jsfiddle.net/g4j8B/

解决方案

You need to place another div above the image and style it to your needs.

Then add the hide() or show() according to the Bootstraps sliding etc.

FIDDLE

HTML:

<li class="span3">
                    <div class="thumbnail">
                        <div class="caption">
                             <h4>Caption Title</h4>

                            <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt.</p>
                            <p><a href="#" class="btn btn-inverse" rel="tooltip" title="Preview"><i class="icon-eye-open"></i></a>  <a href="#" rel="tooltip" title="Visit Website" class="btn btn-inverse"><i class="icon-share"></i></a>

                            </p>
                        </div>
                        <div class="caption-btm">Lorem ipsum dolor sit amet, consectetur adipisicing eli...</div>
                        <img src="http://placehold.it/600x400" alt="ALT NAME">
                    </div>
                     <h4>Item Name</h4>

                </li>

CSS:

.caption-btm{
        background: rgba(0,0,0,0.6);
        width: 100%;
        height: 30px;
        position: absolute;
        bottom: 4px;
        color: #fff;
    }

JQuery:

$('#hover-cap-4col .thumbnail').hover(

                function() {
                    $(this).find('.caption').slideDown(250);
                    $('.caption-btm').hide(100);
                },

                function() {
                    $(this).find('.caption').slideUp(250);
                    $('.caption-btm').show(450);
                });

EDIT

The above Jquery will show and hide every .caption-btm.

But this will hide the specific one that it's being hovered over:

FIDDLE

Jquery:

    $('#hover-img .thumbnail').hover(

            function () {
                $(this).find('.caption').slideDown(250);
                $(this).find('.caption-btm').hide(250);
            },

            function () {
                $(this).find('.caption').slideUp(250);
                $(this).find('.caption-btm').show(250);
            });
