Is $.get of jquery asynchronous?

问题:

I was wondering whether I should use asynchronous calls on my website or not. I know to specify this explicitly I need to use

$.ajax

however initially I tried using $.get and although the server had to return lots of information, my browser didn't stuck and I could navigate without any problems.

I searched a little bit online about it, however I'm still not 100% certain about the difference between the two.

If $.get is asynchronous then what's the point of $.ajax? And if it's not, then again seeing how I had no navigation problems with $.get, what's the point of using $.ajax?

thanks in advance

回答1:

Yes, $.get is asynchronous. From the documentation:

This is a shorthand Ajax function, which is equivalent to:

$.ajax({
  url: url,
  data: data,
  success: success,
  dataType: dataType
});

...and as that doesn't have the async option, async defaults to true. (Note that async will be going away entirely in a future version of jQuery; it will always be true.)

If $.get is asynchronous then what's the point of $.ajax?

$.ajax gives you control over lot more options. $.get is just a shortcut.

回答2:

$.get is simply a shorthand for:

$.ajax({
  url: url,
  data: data,
  success: success,
  dataType: dataType
});

As stated by the jQuery documentation, $.get is a convenience wrapper for the more low-level $.ajax.
