jQuery each callback
提问by NoNameZ
How to use callbacks on jQuery eachfunction?
如何在jQuery 每个函数上使用回调？
I am trying something like:
我正在尝试类似的东西：
$.each(images, function(key, value) {
new_images+= '<li><a href="'+value+'"><img src="'+value+'" alt="'+[key]+'" /></a></li>';
}, function (){
$('#Gallery').remove();
$('body').append('<ul class="gallery">'+new_images+'</ul>');
});

$.each();is a synchronous function. That means you don't need a callback function inside because any code you write after $.each();will run affter $.each();ends.
$.each();是一个同步函数。这意味着您不需要内部的回调函数，因为您之后编写的任何代码$.each();都会在$.each();结束后运行。

What's wrong with this code? You don't need a callback for $.each.
这段代码有什么问题？您不需要回调$.each.
$.each(images, function(key, value) {
new_images+= '<li><a href="'+value+'"><img src="'+value+'" alt="'+[key]+'" /></a></li>';
});
$('#Gallery').remove();
$('body').append('<ul class="gallery">'+new_images+'</ul>');

Do you mean this?
你是这个意思吗？
$.each(images, function(key, value) {
new_images+= '<li><a href="'+value+'"><img src="'+value+'" alt="'+[key]+'" /></a></li>';
});
function myMethod(){
$('#Gallery').remove();
$('body').append('<ul class="gallery">'+new_images+'</ul>');
};
myMethod();

I have now a solution for an .each-callback!
我现在有一个 .each-callback 的解决方案！
I had to do an ajax-request for each element in an array. So I made a div-container with all the div-elements for each element. Each time a load was made, the div-element changed to green and .slideUp, after .remove. And each time i asked if the div-container is empty. If yes, I know, all elements are fully loades (because removed).
我必须对数组中的每个元素执行 ajax 请求。所以我用每个元素的所有 div 元素制作了一个 div 容器。每次加载时，div 元素在 .remove 之后变为绿色和 .slideUp。每次我问 div 容器是否为空时。如果是，我知道，所有元素都已满载（因为已删除）。
Here a part of my code:
这是我的代码的一部分：
<script>
$(document).ready( function() {
$.each(myChannels, function(index, value) {
$("#tag_"+value).load('getxmls/ajaxrenewchannel/channel:'+value, function() {
$("#tag_"+value).removeClass('alert-info').addClass('alert-success');
$("#tag_"+value).slideUp('600', function () {
$("#tag_"+value).remove();
if( $('#loadcontainer').is(':empty') ) {
window.location = 'feeds/';
}
});
});
});
});
</script>
Hope this helps somebody out there...

Not sure about the callback you meant. I guess this is what you are looking for
不确定你的意思是回调。我想这就是你要找的
$('#Gallery').remove();
var selectItems='<ul class="gallery">';
$.each(images, function(key, value) {
selectItems+= '<li><a href="'+value+'">
<img src="'+value+'" alt="'+[key]+'" /></a></li>';
});
selectItems+= '</ul>';
$('body').append(selectItems);
