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
var xhr = $.ajax(opts); xhr.abort();
Note that the
jqXHR object is effectively just an extension of
XMLHttpRequest itself also has an
abortis sent from the client to the server. Each
jqXHRobject represents one single request. If you call the
abortmethod of a single instance of
jqXHR, that single request is cancelled - James Allardice 2012-04-04 21:39
