Question

I’ve a web application which calls a webservice with ajax. This webservices returns me the configuraiton for my app, so the ajax call needs to be set at {async:false}.
Everything works fine when my server is up, but in the case it’s not, my browser just freezes. Even if I set a timeout in my ajax call setup.
I’ve a error handler function which is never called even if the timeout is passed.

Someone has ever been confronted to that situation ?

@Edit : My problem can be solved by doing asynchronous call

Answer 1

As the browser is single threaded it would be better to process the config
returned in the callback success, and handle any errors in the error callback.

$.ajax({
  url: "mydomain.com/url",
  type: "GET",
  dataType: "json",
  data: $.param( $("Element or Expression") ),

  complete: function() {
    //called when complete
  },

  success: function() {
    //called when successful
 },

  error: function() {
    //called when there is an error
  },
});
