我有一个分解为 DIVS 的 HTML 页面。每个 div 包含一个特定的部分。一次只显示一个部分。我的要求是在每个部分从一个部分移动到另一个部分时刷新它。请查看以下 URL 中的代码,

    // overwrite $jScroller to supply asynchronous callback when end has been reached:
    $jScroller.scroll = function() {
      for (var i in $jScroller.config.obj) {

该页面基本上显示 Activity1 然后 Activity2 等等。我的要求是在显示内容之前从 Activity1 移动到 Activity2 时刷新内容。这样我就可以从服务器获得最新信息。
