I have a javascript remoting method which is called on keypress in an input box, but when the new call is made, is it possible to abort the previous processing? Please let me know if we can achieve this

  • Ritzy have you already gone through the documentation ? Adding such details will help others to get more insight into your questions. When I last used js remoting I didn't think this was possible, but maybe there are clever JS ways to acomplish this. Commented Apr 1, 2016 at 13:50
  • You may have to build your own rest service, the you will be able to abort previous call. Commented Apr 1, 2016 at 13:56
  • Not technically possible but it does buffer calls made close together "JavaScript remoting optimizes requests that are executed close to each other in time and groups the calls into a single request. This buffering improve the efficiency of the overall request-and-response cycle, but sometimes it’s useful to ensure all requests execute independently." so it may be a mute point: developer.salesforce.com/docs/atlas.en-us.pages.meta/pages/…

I don't know if there's a way to abort a call that has already been made but one way I would handle something like this is to utilize the Js 'setTimeout' function. Here is my take:

<input name='test' onkeypress='handleCalls(event)'/>
  function handleCalls(e){
    if(typeof(timeoutId) !== 'undefined')

    timeoutId = window.setTimeout(function(){
      // Your Js Remoting call here
    }, 500);

This will wait at least 500ms after a keypress to make the remoting call, and reset the timer on each keypress. You can adjust the timer to be faster or slower without affecting the behavior. Just note that JS timing is not very reliable in that respect.

Hope this helps!
