如何拥有在AJAX加载无限滚动 [英] How to have infinite scroll within ajax loading

问题描述

理念：加载阿贾克斯的一个div内容随即被无限滚动加载相同的分区中的接下来页面内容

Idea: Load the a div content by ajax then load the next page content within the same div by infinite scroll.

1。加载通过AJAX：

• 的想法是， #dhvc_id 单击第一次加载页面时，那么 ID 是考虑到function.php其定位相应的文件，然后分析它在同一个分区。

• Idea is that #dhvc_id is clicked when the page is first loaded, then the id is given to the function.php which locates the appropriate file then parse it on the same div.

demo.php

<?php
/**
* Template Name: Demo
*/

get_header(); ?>

<div id="primary" class="content-area">
    <div id="content" class="site-content" role="main">
        <div class="dhvc_demo" id="dhvc_id"></div>              
    </div><!-- #content -->
</div><!-- #primary -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>

<script>

 //To trigger initial click
 jQuery(window).load(function() { 
    jQuery("#dhvc_id" ).trigger( 'click' );  
    return false;       
    }); 
 //Ajax loading
 jQuery(document).ready(function() {
    jQuery('#dhvc_id').click(function(e) {
        e.preventDefault();

        var tab_id = jQuery(this).attr('id'); 

        jQuery.ajax({
            type: "GET",
            url: "<?php echo admin_url('admin-ajax.php'); ?>", 
            dataType: 'html',
            data: ({ action: 'royal_front_tab', id: tab_id}),
            success: function(data){
                  jQuery('.dhvc_demo').html(data);


        },
        error: function(data)  
        {  
        alert("Error!");
        return false;
        }  

        }); 

 }); 
 }); 

</script>

Function.php

//Ajax call for front page
function royal_front_tab_callback() {  
$template_part_path = 'page-parts/01_home_' . $_GET['id'];
get_template_part($template_part_path);
exit;
}
add_action('wp_ajax_royal_front_tab', 'royal_front_tab_callback');
add_action('wp_ajax_nopriv_royal_front_tab', 'royal_front_tab_callback');

01_home_dhvc_id.php

<?php echo do_shortcode('[some_shortcode]'); ?>

所以，这本身只是正常（阿贾克斯正常工作）。

So, This itself works just fine (Ajax works fine).

2。通过加载无限滚动下一个内容：

Function.php

function custom_theme_js(){
wp_register_script( 'infinite_scroll',  get_template_directory_uri() . '/custom_js/jquery.infinitescroll.min.js', array('jquery'),null,false );
wp_enqueue_script('infinite_scroll');

}
add_action('wp_enqueue_scripts', 'custom_theme_js');

function custom_infinite_scroll_js() {
{ ?>
<script>
jQuery('.royal_card.dhvc-woo-row-fluid.dhvc-woo-grid-list').infinitescroll({
    navSelector  : jQuery('.dhvc-woo-pagination'),
    nextSelector : jQuery('.dhvc-woo-pagination > a.next'),
    itemSelector :  '.royal_card.dhvc-woo-row-fluid.dhvc-woo-grid-list >    .royal_card_outer.royal_card_content_grid',
    contentSelector: jQuery('.royal_card.dhvc-woo-row-fluid.dhvc-woo-grid-list'),
msgText: "fdfgdg "  
},function(newElements){
    jQuery('.dhvc-woo-separator').remove();
    jQuery('.royal_card.dhvc-woo-row-fluid.dhvc-woo-grid-list >  .royal_card_outer.royal_card_content_grid').after('');
});
</script>
<?php
}
}
add_action( 'wp_footer', 'custom_infinite_scroll_js',100 );

这工作也很不错，只有当内容不最初由AJAX加载。

This works just fine as well, only when the content is not initially loaded by the ajax.

下面是我的意思是：

情景1：仅无限滚动（内容没有被AJAX加载）

http://sevek.staging.wpengine.com/dhvc_working-demo/

这是不被加载的分页AJAX 有以下的href 设置：

<a href="http://sevek.staging.wpengine.com/dhvc_working-demo/page/2/">2</a>

情景2：两个阿贾克斯加载和无限滚动（内容是通过AJAX加载）＆LT; - 我试图实现，但分页的URL（检查元素）进行修改

http://sevek.staging.wpengine.com/dhvc-test/

这是分页被加载AJAX 有以下的href 设置：

<a href="http://sevek.staging.wpengine.com/wp-admin/admin-ajax.phppage/2/?action=royal_front_tab&amp;id=dhvc_id">2</a>

正如你所看到的，当内容是通过AJAX加载，链接变得有些古怪，它现在包含可湿性粉剂管理员/管理员，ajax.phppage在URL中，不存在和无限滚动找不到了。

As you can see, when the content is loaded by ajax, the url becomes somewhat odd, and it now contains "wp-admin/admin-ajax.phppage" in the url, which does not exist and the infinite scroll cannot find it.

所以，当我检查元素督察，我得到了以下修改脚本。

So, when I checked the element inspector, I got the following "modified" script .

修改后的脚本

 //To trigger initial click
 jQuery(window).load(function() { 
    jQuery("#dhvc_id" ).trigger( 'click' );  
    return false;       
    }); 
 //Ajax loading
 jQuery(document).ready(function() {
    jQuery('#dhvc_id').click(function(e) {
        e.preventDefault();

        var tab_id = jQuery(this).attr('id'); 

        jQuery.ajax({
            type: "GET",
            url: "http://sevek.staging.wpengine.com/wp-admin/admin-ajax.php", 
            dataType: 'html',
            data: ({ action: 'royal_front_tab', id: tab_id}),
            success: function(data){
                  jQuery('.dhvc_demo').html(data);

                jQuery('.dhvc-woo-row-fluid.dhvc-woo-grid-list').infinitescroll({
                        navSelector  : jQuery('.dhvc-woo-pagination'),            
                        nextSelector : jQuery('.dhvc-woo-pagination > a.next'),    
                        itemSelector :  '.dhvc-woo-row-fluid.dhvc-woo-grid-list > .dhvc-woo-row-fluid',
                        contentSelector: jQuery('.dhvc-woo-row-fluid.dhvc-woo-grid-list'),
                        msgText: " "
                    },function(newElements){
                        jQuery('.dhvc-woo-separator').remove();
                        jQuery('.dhvc-woo-row-fluid.dhvc-woo-grid-list > .dhvc-woo-row-fluid').after('<div class="dhvc-woo-separator"></div>');
                    });
        },
        error: function(data)  
        {  
        alert("Error!");
        return false;
        }  

        }); 

 }); 
 }); 

这是怎么回事？我怎样才能使它工作？

What is happening? How can I make it work?
