Question

我在首页添加了一个加载更多按钮。该按钮将在每15个帖子后加载更多帖子。我添加了所有必要的代码，但是当我点击按钮时没有任何加载。有没有人有办法解决吗？或者，如果只有更好，更有效的方式加载更多帖子，我会喜欢其他解决方案。我一直试图让这个工作几周，而我却无法得到它。

JS

 // AJAX to grab more posts, wrap with a vanilla javascript or
  // jQuery click event function.
  function loadMorePosts(pageNumber, postsPerPage) {
    var query = 'action=load_more&page_no=' + pageNumber + 
        '&loop_file=loop&posts_per_page=' + postsPerPage;

    jQuery.ajax({
        url: '/wp-admin/admin-ajax.php',
        type: 'post',
        data: query,
        success: function(response){
            // handle response
        }
    });
}

EDITED JS

 function loadMorePosts(pageNumber, postsPerPage) {

  var query = 'action=load_more&page_no=' + pageNumber + 
    '&loop_file=loop&posts_per_page=' + postsPerPage;

  jQuery.ajax({
    url: '/wp-admin/admin-ajax.php',
    type: 'post',
    data: query,
    success: function(response){
        // handle response
    }
  });
}
  jQuery(document).ready(function() {
    jQuery('#load-more').on('click', function(){
    loadMorePosts(pageNumber, postsPerPage)
  })
})

我认为这里的问题是你没有将loadMorePosts函数附加到按钮上的事件监听器。由于您的按钮的ID为“load-more”，因此您可以执行以下操作：

function loadMorePosts(pageNumber, postsPerPage) {

  var query = 'action=load_more&page_no=' + pageNumber + 
    '&loop_file=loop&posts_per_page=' + postsPerPage;

  jQuery.ajax({
    url: '/wp-admin/admin-ajax.php',
    type: 'post',
    data: query,
    success: function(response){
        // handle response
    }
  });
}
$('#load-more').on('click', function(){
  loadMorePosts(pageNumber, postsPerPage)
})

一些警告。我不知道你是如何检索pageNumber和postsPerPage值的。

这个答案假设您在html加载完成后加载脚本。如果不是这样，您需要执行以下操作：

$(document).ready(function() {
  $('#load-more').on('click', function(){
    loadMorePosts(pageNumber, postsPerPage)
  })
})

单击时加载更多按钮不会加载任何内容
