jQuery-如何在单击链接时更改图像src [英] JQuery - how can I change an image src on click of a link

问题描述

我正在使用JQuery画廊显示具有不透明滑动描述的图像.我需要添加链接列表，以便用户可以覆盖单击链接时显示的图像. 单击链接后如何覆盖图库图像?

I am using a JQuery gallery to display an image with opaque sliding description. I need to add a list of links so that the user can override the image displayed on click of a link. How can I override the gallery image on click of the link?

 $(document).ready(function() {     

        //Execute the slideShow
        slideShow();

    })

    function slideShow() {

            $('#gallery a').css({opacity: 0.0});
        $('#gallery a:first').css({opacity: 1.0});
        $('#gallery .caption').css({opacity: 0.7});
        $('#gallery .caption').css({width: $('#gallery a').find('img').css('width')});
        $('#gallery .content').html($('#gallery a:first').find('img').attr('rel'))
        .animate({opacity: 0.7}, 400);
            setInterval('gallery()',6000);
        }

    function gallery() {

        var current = ($('#gallery a.show')?  $('#gallery a.show') : $('#gallery a:first'));

        var next = ((current.next().length) ? ((current.next().hasClass('caption'))? $('#gallery a:first') :current.next()) : $('#gallery a:first'));   

        var caption = next.find('img').attr('rel'); 
        next.css({opacity: 0.0})
        .addClass('show')
        .animate({opacity: 1.0}, 1000);

        current.animate({opacity: 0.0}, 1000)
        .removeClass('show');

        $('#gallery .caption').animate({opacity: 0.0}, { queue:false, duration:0 }).animate({height: '1px'}, { queue:true, duration:300 }); 

        $('#gallery .caption').animate({opacity: 0.7},100 ).animate({height: '100px'},500 );

        $('#gallery .content').html(caption);

    }

    <div id="gallery">
                            <a href="#" class="show">
                                <img src="images/storm2.jpg" alt="text in here" title="" width="480" height="260"
                                    rel="<h3>Description</h3>description goes in here "</a> <a href="#">
            <img src="images/storm1.jpg" alt="text in here" title="" width="480" height="260"
                rel="<h3>Description 2</h3>" />
        </a>...... ...... ......
                            <div class="caption">
                                <div class="content">
                                </div>
                            </div>
                        </div>
                        <div class="clear">
                        </div>

推荐答案

$("a.mylink").click(function(event){
  $("img.myimage").attr("src","image2.jpg");
});

从链接中加载源代码也非常容易:

Loading the source from the link is very easy as well:

$("a.mylink").click(function(event){
  event.preventDefault();
  var newSRC = $(this).attr("href");
  $("img.myimage").attr("src", newSRC);
});
