我试图创建一系列事件,如下所述:
1)用户点击.post-link
会将页面滚动到顶部(如果还没有)。
2)#project-container
会露出#loading-animation
。
3)帖子将通过Ajax加载。
现在,当我点击.post-link
时,一切似乎都会立刻发生。如何格式化下面的代码以确保一个事件在另一个事件完成后发生?
基本上,this is what I'm trying to recreate。当您点击帖子时,请注意隐藏容器如何打开以显示加载动画,然后一旦内容加载,它就会打开以显示内容。
JS
$('.post-link').click(function(e) {
e.preventDefault();
$('html, body').animate({
scrollTop : 0
},500, function() {
$('#loading-animation').show();
});
var post_id = $(this).attr('rel');
var ajaxURL = site.ajaxurl;
$.ajax({
type: 'POST',
url: ajaxURL,
data: {'action': 'load-content', post_id: post_id },
success: function(response) {
$('#project-container').html(response);
$('#loading-animation').hide();
return false;
}
});
});

加载第一篇文章后,您的#loading-animation正在删除,您无法再与其进行互动。
尝试将ajax内容加载到#project-container
中的另一个包装元素中<强> HTML 强>
<div id="project-container">
<img id="loading-animation" src="http://i.imgur.com/5RMfW8P.gif" style="display:none">
<div class="ajax-wrapper"></div>

success: function(response) {
$('#project-container .ajax-wrapper').html(response);
$('#loading-animation').hide();
return false;

您必须将Ajax调用放入.show()函数中才能链接动画。
$('.post-link').click(function(e) {
e.preventDefault();
var post_id = $(this).attr('rel');
var ajaxURL = site.ajaxurl;
$('html, body').animate({
scrollTop : 0
},500, function() {
$('#loading-animation').show(500, function() {
$.ajax({
type: 'POST',
url: ajaxURL,
data: {'action': 'load-content', post_id: post_id },
success: function(response) {
$('#project-container').html(response);
$('#loading-animation').hide();
return false;
}
});
});
});
});
