我正在使用JQuery画廊显示带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?
<script>
$(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);
}
</script>
<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>
$("a.mylink").click(function(event){
$("img.myimage").attr("src","image2.jpg");
});
从链接加载源代码也很容易:
$("a.mylink").click(function(event){
event.preventDefault();
var newSRC = $(this).attr("href");
$("img.myimage").attr("src", newSRC);
});
jQuery('#link').click(function() {
jQuery('#image').attr('src',jQuery(this).attr('alt'));
}
此方法有点像黑客,您可以在其中作弊,并将src路径存储到链接的alt选项卡中。
[如果您想按照书上的说明做,我建议您将逻辑与视觉分开。例如,您创建一个如下数组:
myArray['link1'] = 'url1';
myArray['link2'] = 'url2';
数组键将与链接的id标记相同:
<a id="link1" href="foo">bar</a> etc...
如果您这样做,JavaScript会发生如下变化:
jQuery('#link').click(function() {
jQuery('#image').attr('src',myArray[this.id]);
}
