How would I get data from another file. For example a username check:
$.ajax({
type: "POST",
url: "check.php",
data: "username="+ usr,
success: function(msg){ }
)}
That example uses ajax, I was wondering how I would do something similar, without any javascript plugin/extension.
IMHO,not possible.
$("#randomdiv").load("load.php")
You cannot do that without JavaScript.
What you can use is:
If you want to get the file over HTTP, then no — that is, by definition, Ajax.
If you are happy getting the file from the user via a <input type="file"> then you can use the File API.
If, by Ajax, you actually mean "jQuery's ajax method", then you can do it directly using XMLHttpRequest.
