Xmlhttprequest cannot load xml file

In other words, JavaScript execution pauses at send and resumes when the response is received. Somewhat like alert or prompt commands.

It might look good, but synchronous calls are used rarely, because they block in-page JavaScript till the loading is complete. In some browsers it becomes impossible to scroll. Many advanced capabilities of XMLHttpRequest , like requesting from another domain or specifying a timeout, are unavailable for synchronous requests.

Also, as you can see, no progress indication. Because of all that, synchronous requests are used very sparingly, almost never. XMLHttpRequest allows both to send custom headers and read headers from the response. Several headers are managed exclusively by the browser, e. Referer and Host. The full list is in the specification. XMLHttpRequest is not allowed to change them, for the sake of user safety and correctness of the request.

Gets the response header with the given name except Set-Cookie and Set-Cookie2. The separator between the name and the value is always a colon followed by a space ": ". An origin is defined by the scheme, host, and port of a URL. It is a browser security feature that restricts how documents and scripts on one origin can interact with resources on another origin. This would let it access potentially sensitive data from another web page as well as perform actions on other web pages without user consent.

Thanks in Advance. Here is the code: navigator. Other versions: cordova But, there's a check immediately below the async call something like this: this. So I have to take promise route and modified the code like below: this. Ready to print console. Does anybody know why this is, and how I can fix it? If you want to use the example above on one of your own web pages, the XML files you load must be located on your own server. The file can be any kind of file, like. To send the request asynchronously, the async parameter of the open method has to be set to true:.

Sending asynchronously requests is a huge improvement for web developers. Many of the tasks performed on the server are very time consuming. By sending asynchronously, the JavaScript does not have to wait for the server response, but can instead:. If the server is busy or slow, the application will hang or stop.
