在AJAX页面更新后重新初始化jQuery插件 [英] Reinitialize jQuery plugin after AJAX page update

问题描述

我在主页上有一个图像轮播。为了呈现它我使用Jquerytools（可滚动+导航器）

I have an image carousel in home page. To render it i use Jquerytools ( scrollable+navigator )

我以这种方式触发jQuery初始化程序脚本：

I trigger the jQuery initializer script in this way:

$(window).load(function(){
   $("#today-news-carousel").scrollable({ vertical: true, mousewheel: true }).navigator({ navi: '#today-news-navigator' });

 });

此轮播的内容可以通过AJAX调用进行更新。
拨打此电话后，我需要重新初始化此轮播。
这里是调用AJAX的函数：

The content of this carousel can be updated by AJAX call. After this call i need to reinitialize this carousel. Here the function that makes AJAX call:

  $(document).on('click', '.nav-highlight', function() {

      var requestDateArray = $(this).attr('data-thedate').split('-');
      var d = new Date();
      var requestedDate = new Date(requestDateArray[0], (requestDateArray[1]-1), requestDateArray[2]);
      var today = new Date(d.getFullYear(), d.getMonth(), d.getDate());
      if (requestedDate > today) {
          return
      }else {
        $.ajax({
          type: "POST",
          url: templateDir+'/highlight-news-navigator.php',
          context: this,
          dataType: "html",
          data: { date: $(this).attr('data-thedate') },
          beforeSend: function(){ 
          },
          success: function(data) {
            $('.today-news').fadeOut('fast', function(){
              $(this).empty().html(data).fadeIn('fast');
            });
          },
          complete: function(){
            $("#today-news-carousel").scrollable({ vertical: true, mousewheel: true })
            .navigator({ navi: '#today-news-navigator' });   
          }
        });

      }

  });

我尝试重新初始化插件但是我在控制台中出现以下错误：

in the "complete" callback function i try to reinitialize the plugin but i have the following error in console:

TypeError: $(...).scrollable(...).navigator is not a function
.navigator({ navi: '#today-news-navigator' });

我无法理解为什么当我加载页面时它正常工作，当我重新初始化它似乎找不到它.navigator方法...

I cannot understand why it works correctly when i load the page and when i reinitialize it seems it cannot find .navigator method...

推荐答案

感谢Archer的帮助我找到了解决方案。
重新初始化插件的脚本必须位于fadeIn（）回调中。
这里的工作代码：

Thank to the help of a Archer i found the solution. The script to reinitialize the plugin had to be located in the fadeIn() callback. Here the working code:

  $(document).on('click', '.nav-highlight', function() {

      var requestDateArray = $(this).attr('data-thedate').split('-');
      var d = new Date();
      var requestedDate = new Date(requestDateArray[0], (requestDateArray[1]-1), requestDateArray[2]);
      var today = new Date(d.getFullYear(), d.getMonth(), d.getDate());
      if (requestedDate > today) {
          return
      }else {
        $.ajax({
          type: "POST",
          url: templateDir+'/highlight-news-navigator.php',
          context: this,
          dataType: "html",
          data: { date: $(this).attr('data-thedate') },
          beforeSend: function(){ 
          },
          success: function(data) {
            $('.today-news').fadeOut('fast', function(){
              $(this).empty().html(data).fadeIn('fast', function(){
                $("#today-news-carousel").scrollable({ vertical: true, mousewheel: true }).navigator({ navi: '#today-news-navigator' });   
              });
            });
          },
        });

      }

  });
