如何查看XMLHttpRequest对象

Question

I am new to JavaScript, so this is quite a basic question.

I am creating a XMLHttpRequest object and am calling the setRequestHeader() method. For debugging, I want to be able to see the headers I have set on the XMLHttpRequest object before I call send() .

There does not seem to be an API to getRequestHeader() , so is there another way to view my object as a string so I can debug?.

Update: Sorry, I need to make things clearer. I am writing a PhoneGap application and do not have access to a Chrome console.

Answer 1

you can use (the available methods in) the console object to debug your scripts.

var object = {test:1};
console.log(object);

Reference: console

Answer 2

在chrome上，使用控制台的“网络”标签，在firefox上，您可能需要使用firebug才能执行操作，您将看到有关xhr的所有信息
