利用AJAX实现WordPress中的文章列表及评论的分页功

<!-- 包含所有文章的容器 -->
<div id="content">
  <!-- 各文章的容器 -->
  <div class="post"></div>
  <div class="post"></div>
  <div class="post"></div>
  <div class="post"></div>
  <div class="post"></div>
</div>

<div id="pagination"><?php next_posts_link(__('LOAD MORE')); ?></div>

// 使用 live() 使 js 对通过 Ajax 获得的新内容仍有效
  $("#pagination a").live("click", function(){
    $(this).addClass("loading").text("LOADING...");

        result = $(data).find("#content .post");

        // 渐显新内容
        $("#content").append(result.fadeIn(300));
        $("#pagination a").removeClass("loading").text("LOAD MORE");
        if ( nextHref != undefined ) {
          $("#pagination a").attr("href", nextHref);
