推荐答案

首先，您需要使用Ajax请求来调用脚本.所有jQuery ajax方法都提供函数回调，该函数回调在调用完成时被调用.您可以在提出请求时显示进度条，并在完成后将其隐藏:

At first you need to call the script using an Ajax request. All jQuery ajax methods offer function callbacks that are called when the call is completed. You can show the progress bar when you make the request and hide it, when it is finished:

$("#MyProgressBar").show();
$("#placeholder").load(myurl, function() {
  $("#MyProgressBar").hide();
});

您还可以使用 BlockUI 之类的插件.

You could also use a plug-in like BlockUI.
