jQuery: if class=active?
提问by Karem
$(document).ready(function() {
$('a#fav').bind('click', function() {
addFav(<?php echo $showUP["uID"]; ?>);
});
});
I need to modify this so if the a#fav has class="active" then it should do
我需要修改这个,所以如果 a#fav 有 class="active" 那么它应该做
removeFav(<?php echo $showUP["uID"]; ?>);

相反,我该怎么做?
回答by Derek H
You want to use the hasClass
function
您想使用该hasClass
功能
$(document).ready(function() {
$('a#fav').bind('click', function() {
if($(this).hasClass('active')) {
removeFav(<?php echo $showUP["uID"]; ?>);
}
else {
addFav(<?php echo $showUP["uID"]; ?>);
}
});
});
EDIT: And just for fun, another way to write it in a more condensed format
编辑:只是为了好玩,另一种以更简洁的格式编写它的方法
$(function() {
$('a#fav').bind('click', function() {
var uID = <?php echo $showUP["uID"]; ?>;
($(this).hasClass('active') ? removeFav : addFav)(uID);
});
});
