ajax数据的jquery分页

Question

我有 3 个标签，我在点击功能中编写了 ajax 来获取帖子。

我已经简化了我的编码：

在文档中准备好

$.ajax({
type : "GET",
url:"xxx",
data:{ method:'wire.get_posts', limit:'10', offset:'0', context:'all' },            
dataType:"json",
success:function(all_data) {
    $("#tabs-1").append(all_element);
}
});

这是我的分页

//how much items per page to show
var show_per_page = 2; 
//getting the amount of elements inside content div
var number_of_items = $('#tabs-1').children().size();
//calculate the number of pages we are going to have
var number_of_pages = Math.ceil(number_of_items/show_per_page);

//set the value of our hidden input fields
$('#current_page').val(0);
$('#show_per_page').val(show_per_page);

//now when we got all we need for the navigation let's make it '

/* 
what are we going to have in the navigation?
- link to previous page
- links to specific pages
- link to next page
*/
var navigation_html = '<a class="previous_link"   
href="javascript:previous();">Prev</a>';
var current_link = 0;
while(number_of_pages > current_link){
navigation_html += '<a class="page_link" href="javascript:go_to_page(' + current_link   

+')" longdesc="' + current_link +'">'+ (current_link + 1) +'</a>';
current_link++;
}
navigation_html += '<a class="next_link" href="javascript:next();">Next</a>';

$('#page_navigation').html(navigation_html);

//add active_page class to the first page link
$('#page_navigation .page_link:first').addClass('active_page');

//hide all the elements inside content div
$('#tabs-1').children().css('display', 'none');

//and show the first n (show_per_page) elements
$('#tabs-1').children().slice(0, show_per_page).css('display', 'block');

//pagination functions
function previous(){

new_page = parseInt($('#current_page').val()) - 1;
//if there is an item before the current active link run the function
if($('.active_page').prev('.page_link').length==true){
go_to_page(new_page);
}

}

function next(){
new_page = parseInt($('#current_page').val()) + 1;
//if there is an item after the current active link run the function
if($('.active_page').next('.page_link').length==true){
go_to_page(new_page);
}

}
function go_to_page(page_num){
//get the number of items shown per page
var show_per_page = parseInt($('#show_per_page').val());

//get the element number where to start the slice from
start_from = page_num * show_per_page;

//get the element number where to end the slice
end_on = start_from + show_per_page;

//hide all children elements of content div, get specific items and show them
$('#tabs-1').children().css('display', 'none').slice(start_from, end_on).css('display', 
'block');

/*get the page link that has longdesc attribute of the current page and add active_page 
class to it
and remove that class from previously active page link*/
$('.page_link[longdesc=' + page_num 
+']').addClass('active_page').siblings('.active_page').removeClass('active_page');

//update the current page input field
$('#current_page').val(page_num);
}
//pagination functions

我在 ajax 成功追加 html 元素

如果是静态内容，我的分页可以正常工作

HTML：

<div id="tabs">
<ul>
<li><a id="ui-id-1" href="#tabs-1">All</a></li>
<li><a id="ui-id-2" href="#tabs-2">Mine</a></li>
<li><a id="ui-id-3" href="#tabs-3">Friends</a></li>
</ul>

<div id="tabs-1">
</div>

<div id="tabs-2">    
</div>

<div id="tabs-3">
</div>
</div>
<br>

<!-- An empty div which will be populated using jQuery --> 
<div id='page_navigation'></div>

就目前而言，您的“分页代码”似乎没有在您的 AJAX 调用成功后立即被调用：在它执行时，数据不一定是从您的服务器传输的。结果，它没用；同时对于静态内容，数据已经在您的#tabs-1 中，因此可以正常工作。

提醒一下，AJAX means Asynchronous Javascript and XML。

然后，您应该将所有分页代码包装到 ajax 调用的 success 方法中，这样它只会在检索到数据时进行分页。
