图像悬停上的div显示（与淡入淡出）

Question

对于您在http://www.stacklaw.com.au/web/page/Our_People_Lawyer_Finder上查看的任何人物配置文件，我想为显示的“灯箱”框架添加一些功能，以便每个人的报价淡入当鼠标悬停在人的图像上时，鼠标从图像移开时会消失。

这将是一个奖金，如果我可以让div淡入，显示1秒，淡出在页面（灯箱）加载，以通知观众图像有内容...但不是必需的。

感谢

该网站的开发者使用的是JS所谓的“facebox”和主文件为它包括：

* Facebox (for jQuery) 
* version: 1.3 
* @requires jQuery v1.2 or later 
* @homepage https://github.com/defunkt/facebox 
* 
* Licensed under the MIT: 
* http://www.opensource.org/licenses/mit-license.php 
* 
* Copyright Forever Chris Wanstrath, Kyle Neath 
* 
* Usage: 
* 
* jQuery(document).ready(function() { 
* jQuery('a[rel*=facebox]').facebox() 
* }) 
* 
* <a href="#terms" rel="facebox">Terms</a> 
* Loads the #terms div in the box 
* 
* <a href="terms.html" rel="facebox">Terms</a> 
* Loads the terms.html page in the box 
* 
* <a href="terms.png" rel="facebox">Terms</a> 
* Loads the terms.png image in the box 
* 
* 
* You can also use it programmatically: 
* 
* jQuery.facebox('some html') 
* jQuery.facebox('some html', 'my-groovy-style') 
* 
* The above will open a facebox with "some html" as the content. 
* 
* jQuery.facebox(function($) { 
*  $.get('blah.html', function(data) { $.facebox(data) }) 
* }) 
* 
* The above will show a loading screen before the passed function is called, 
* allowing for a better ajaxy experience. 
* 
* The facebox function can also display an ajax page, an image, or the contents of a div: 
* 
* jQuery.facebox({ ajax: 'remote.html' }) 
* jQuery.facebox({ ajax: 'remote.html' }, 'my-groovy-style') 
* jQuery.facebox({ image: 'stairs.jpg' }) 
* jQuery.facebox({ image: 'stairs.jpg' }, 'my-groovy-style') 
* jQuery.facebox({ div: '#box' }) 
* jQuery.facebox({ div: '#box' }, 'my-groovy-style') 
* 
* Want to close the facebox? Trigger the 'close.facebox' document event: 
* 
* jQuery(document).trigger('close.facebox') 
* 
* Facebox also has a bunch of other hooks: 
* 
* loading.facebox 
* beforeReveal.facebox 
* reveal.facebox (aliased as 'afterReveal.facebox') 
* init.facebox 
* afterClose.facebox 
* 
* Simply bind a function to any of these hooks: 
* 
* $(document).bind('reveal.facebox', function() { ...stuff to do after the facebox and contents are revealed... }) 
*

Answer 1

在把这个代码在某处的个人资料页：

<script type="text/javascript"> 
    $(document).ready(function() { 
     $(".qucon").hide(); 
     $("#ProfileMainBody img, .qucon").hover(
       function(){ 
      $(".qucon").fadeIn('fast'); 
       }, 
       function(){ 
      $(".qucon").fadeOut('fast'); 
       } 
     ); 
    }); 
    </script> 

Answer 2

试试这个代码

$('.test').hide(); 
$('.qucon').hover(function() {      
     $('.test').fadeIn();   

    }, function() { 
     $('.test').fadeOut();   
    }); 

参考演示See Demo

希望它可以帮助你

Answer 3

这里是CSS的解决方案。

负载情况。

.qucon{ 
opacity:0; 
} 

悬停情况与过渡。

.qucon:hover{ 
opacity:1; 
transition: background-color 0.2s ease 0s, border 0.2s ease 0s, color 0.2s ease 0s, opacity 0.2s ease-in-out 0s, outline 0.2s ease 0s; 
} 

希望这会有所帮助。
