我有这个工作正常的脚本,它允许用户投票,但我有点想知道如何制作投票按钮,当再次点击它时,它会切换回正常图像!就像堆栈溢出一样:
这是我的脚本:
$(document).ready(function() {
$('.statuses').delegate('.vote_up', 'click', function(e) {
//stop event
e.preventDefault();
//get the id
var the_id = $(this).closest('.message').attr('id').split('_').pop();
//the main ajax request
$.ajax({
context: this,
type: "POST",
// Make sure "this" in the callback refers to the element clicked
data: "action=vote_up&id=" + the_id,
url: "ajax/votes.php",
success: function (msg) {
$(this).siblings("span.vote_count").html(msg).fadeIn();
// get the child <img> and set its src
$(this).children("img").attr("src", "img/uparrowActive.png");
}
});
});
html:
<ul class="statuses">
<li id="set_41" class="message">
<span class="vote_count">0</span>
<a href="#" class="vote_up"><img src="img/uparrow.png" /></a>
这是我想要发生的伪语言:
a user clicks vote image, it changes the image(uparrowActive)
//I've done that already
then
if user clicks the same image again it goes back to normal image(uparrow)
