/* nadeem css */
.newstyles{ font: 20px/18px arial;color: #0B0B0C;margin: 5px 0px 20px 5px;}
.newstyles li{ height: 32px;font: bold 12px/32px arial;color: #0B0B0C;}

}
这是js
$(document).ready(function() {
setTimeout(function() {
// Slide
$('#menu1 > li > a.expanded + ul').slideToggle('medium');
$('#menu1 > li > a').click(function() {
$(this).toggleClass('expanded').toggleClass('collapsed').parent().find('> ul').slideToggle('medium');
});
$('#example1 .expand_all').click(function() {
$('#menu1 > li > a.collapsed').addClass('expanded').removeClass('collapsed').parent().find('> ul').slideDown('medium');
});
$('#example1 .collapse_all').click(function() {
$('#menu1 > li > a.expanded').addClass('collapsed').removeClass('expanded').parent().find('> ul').slideUp('medium');
});
}, 250);
});
这是html
<div id="example1">
<div><a class="expand_all"><img src="images/close.jpg" class="img-swap" /></a><a class="collapse_all"><img src="images/open.jpg" alt="" /></a></div>

推荐答案
假设它是顶部的两个图像，您可以执行以下操作:
Guessing it is the two images in the top, you could do this:
<div>
<a class="expand_all" style="display: none;" onclick="$('.expand_all').hide();$('.collapse_all').show()">
<img class="img-swap" src="images/toggle-buttons_01.png">
</a>
<a class="collapse_all" onclick="$('.expand_all').show();$('.collapse_all').hide()" style="display: inline;">
<img alt="" src="images/toggle-buttons_02.png">
</a>
</div>
简单地隐藏不相关的图片....虽然不是真正交换图片.
Simply hiding the irrelevant one....not really swapping images though.
