I just wanted to ask. I have text input to allow users to type their city.
jQuery has a keyup
event linked to this input and sent an AJAX call after each character change.
I find however many unrequired AJAX calls are sent as the person is typing and depending on the number of results this can slow down performance here.
Is there a way to cancel AJAX calls if a new call is made? Is there a better way to do this?
An example can be seen here: www.datingjapan.co
You can use the abort
method of the jqXHR
object returned by the ajax
method (other AJAX methods like get
and post
return a jqXHR
instance too):
var xhr = $.ajax(opts);
xhr.abort();
Note that the jqXHR
object is effectively just an extension of XMLHttpRequest
, and XMLHttpRequest
itself also has an abort
method.
