嗨我想知道如何点击一个保持课程的链接,直到我点击另一个,它将从中删除该课程,而我刚刚点击的课程将返回该课程?
//animation for secondary content pics
$('#small li').hover(function () {
$(this).addClass('small_list_hover');
}, function () {
$(this).removeClass('small_list_hover');
});
$("h4").append('<em> Image 1</em>').show();
$("#small a").click(function () {
var largePath = $(this).attr("href");
var largeAlt = $(this).attr("title");
$('li').removeClass('small_li_hover');
$('this').addClass('small_li_hover');
$('#largeImg').hide().fadeIn(1000).attr({
src: largePath,
alt: largeAlt
});
$("h4 em").html(" " + largeAlt + " ");
return false;
});

你可以这样做:
$(document).ready(function() {
$("a").click(function() {
$("a").removeClass("active");
$(this).addClass("active");
});
});

试试这个......
$("a").click(function(){
$("a.active").removeClass("active");
$(this).addClass("active");
});
根据问题它应该像是
$("#small a").click(function () {
var largePath = $(this).attr("href");
var largeAlt = $(this).attr("title");
$('li').removeClass('small_li_hover');
$(this).parents('li').addClass('small_li_hover');
$('#largeImg').hide().fadeIn(1000).attr({
src: largePath,
alt: largeAlt
});
$("h4 em").html(" " + largeAlt + " ");
return false;
});

$("#small a").click(function () {
var largePath = $(this).attr("href");
var largeAlt = $(this).attr("title");
//$('li').removeClass('small_li_hover');
// $('this').addClass('small_li_hover'); // your problem is here....
$(this).closest('li').addClass('small_li_hover')
.siblings().removeClass('small_li_hover');
$('#largeImg').hide().fadeIn(1000).attr({
src: largePath,
alt: largeAlt
});
$("h4 em").html(" " + largeAlt + " ");
return false;
});
嗯,我并不感到惊讶。那么,我们这样做怎么样,嗨Reigel,我试过了,但它没有 工作。当我将链接悬停在它上面时 class自行删除!
改变,
$(this).closest('li').addClass('small_li_hover')
.siblings().removeClass('small_li_hover');
之类的,
$(this).closest('li').addClass('small_li_active')
.siblings().removeClass('small_li_active');
然后在你的CSS上,如果你有类似的东西,
.small_li_hover {
color: red;
}
将其更改为
.small_li_active,
.small_li_hover {
color: red;
}
