Problem AjaxStart - ajax synchronous mode

Reported by: elimaoliveiramaster@… Owned by:
Priority: low Milestone: None
Component: ajax Version: 1.7.1
Keywords: Cc:
Blocked by: Blocking:

Description

When the ajax is set to synchronous mode, the object #painelProcessamento is not shown after running the show() method, unless it is running in Firefox.

$("#painelProcessamento").ajaxStart(function() {

$(this).show();

}).ajaxStop(function() {

$(this).hide();

});


$.ajax({ url: url,

contentType: "application/json; charset=utf-8", type: "POST", dataType: "json", data: "{" + p.urlParams + "}", async: false, success: function(jsonData) {

...

}, error: function() {

...

}

});

You can't have your cake and eat it.

Synchronous requests will block the Javascript VM so events won't be fired in a timely fashion. Firefox's behaviour in that instance is quite worrisome.

If you show a panel to avoid interaction (I suppose?) why are you making a synchronous request?

Just to show the user that the system is not locked in the event of any delay in processing.

This personally looks more like an inconsistency in how FF is handling the issue rather than something directly being approached incorrectly by jQuery core. Unless there are actions we want to take on how synchronous mode currently works, closing as wontfix.
