如何读取jQuery中的默认Ajax参数? [英] How can I read the default ajax parameters in jQuery?

问题描述

在jQuery中，我可以使用ajaxSetup设置ajax默认参数，例如:

In jQuery I can set ajax default parameters with ajaxSetup like:

$.ajaxSetup({'async': false});

是否可以阅读它们?这样，对于上面的示例，我知道当前是否将异步设置为false或true?

Is it possible to read them? So that for the example above I knew if async is currently set to false or true?

推荐答案

您可以执行$.ajaxSetup()['cache']，但请不要这样做.不鼓励使用ajaxSetup，因为随着应用程序的增大，这可能会导致行为异常，因为每个Ajax调用都将取决于应用程序的状态，从而导致不可预测性.

You can do this $.ajaxSetup()['cache'], but please don't. The use of ajaxSetup is not encouraged, this may lead to misbehavior as your application grows bigger, because each Ajax call would depend on the state of your application, which leads to unpredictability.

如果确实需要ajax的默认选项，则可以尝试使用$.extend将当前选项与某些方法调用返回的默认选项合并.至少您可以调试并查看将哪些参数传递给您的请求.

If you really need default options for ajax, you could try using $.extend to merge your current options with the default options returned by some method call.. maybe some object injected through requireJs maybe. At least you can debug and see which params are being passed to your request.
