jquery wait for multiple complete events
Solution 1
Sounds like a job for Deferred
: http://api.jquery.com/category/deferred-object/
var load = $.Deferred(function (dfd) {
$('#div1').load(…, dfd.resolve);
}).promise();
var animate = $('html,body').animate(…);
$.when(load, animate).then(function () {
// Do your thing here!
});
Solution 2
var _loadComplete = false;
var _animateComplete = false;
$('#div1').load('...', function() {
// load complete
_loadComplete = true;
checkComplete();
});
$('html,body').animate({
...: ...}, ..., '...', function(){
// animate complete
_animateComplete = true;
checkComplete();
});
function checkComplete() {
if(_loadComplete && _animateComplete)
runThirdFunction();
});
Solution 3
You'll have to keep count of how many of your events have completed, and then use that as a test in your callback:
var complete = 0;
$('#div1').load('...', function() {
complete++;
callback();
});
$('html,body').animate({
...: ...}, ..., '...', function(){
complete++;
callback();
});
function callback(){
if ( complete < 2 ) return;
// both are complete
}
Solution 4
Set a flag in LoadComplete and call your own 'allComplete' function. Set another flag in AnimateComplete and call that same 'allComplete' function.
In allComplete you check if both flags are set. If they are, both async functions are complete and you can call your third function.
Instead of setting flags (separate variables), you can also add 1 to a global counter, that way, you can increase the number of async functions to wait for without having to introduce extra flag variables.
Solution 5
Use:
$('#div1').queue(function(){ /* do stuff */ });
This way you can queue functions to execute one after the other.

I want to use jQuery's
load
function to load some content into a div, and I want to also call jQuery'sanimate
function.$('#div1').load('...', function() { // load complete }); $('html,body').animate({ ...: ...}, ..., '...', function(){ // animate complete });
I don't want to wait for
load
to complete before callinganimate
or vice versa.Following this I want to call a third function, but I don't want to call it until the complete event for both the
load
and theanimate
have been fired.How can I do this?
