在脚本开头的某个地方（可能是按钮的click事件），将按钮的disabled属性设置为true：

Somewhere at the beginning of your script (probably on the button's click event), set the button's disabled attribute to true:

$("#mybutton").attr("disabled", true);

然后，完成后，删除该属性：

Then, when complete, remove that attribute:

$("#mybutton").removeAttr("disabled");

编辑：

如果你想得到（略微）幻想，在你工作的时候改变按钮的文字。如果是图像按钮，您可以将src更改为友好的请稍候消息。以下是按钮文本版本的示例：

If you want to get (slightly) fancy, change the text of the button while you're doing the work. If it's an image button, you can change the src to a friendly "please wait" message. Here's an example of the button text version:

$("#mybutton").click(function() {
  var origVal = $(this).attr("value");

  $(this).attr("value", "Please wait...");
  $(this).attr("disabled", true);

  //Do your processing.

  $(this).removeAttr("disabled");
  $(this).attr("value", origVal);
});
