jQuery event trigger; callback and timing with respect to animations
Perhaps my question deviates from the simplicity of itself: Given I .trigger()
an event, how can I ensure that code following said .trigger()
will not execute until the entire event handler function has completed, including all animations, delays, et al., therein?
I hope I'm missing something here; I'm setting up a UI with a bunch of custom events. Some of the events are really just aggregates of other events; for instance:
// ...
'cb-ui.hide': function(event){
// do stuff to hide
},
'cb-ui.close': function(event){
$(this).trigger('cb-ui.hide');
// more stuff for close
},
// ...
Given there is an animation in the cb-ui.hide
event, like .fadeOut(1500)
, it appears (in my testing) that the remaining // more stuff for close
doesn't wait for the animation to complete in the triggered event. I was thinking (previous to referencing the docs) that .trigger()
would likely have an optional callback argument much like the animation methods:
$(this).trigger('cb-ui.hide', function(event){
// more stuff for close
});
But this doesn't appear to be the case. Since event triggers are not blocking (or don't appear to be at least), what can I do to force the desired functionality, while keeping with the event handler/trigger implementation that I've been building off of?
More specifically:
$('[data-cb-ui-class="window"]').live({
'cb-ui.hide': function(event){
$(this).find('[data-cb-ui-class="content"]').animate({
opacity: 0
}, 1000);
},
'cb-ui.show': function(event){
$(this).find('[data-cb-ui-class="content"]').animate({
opacity: 1
}, 1000);
}
'cb-ui.close开发者_开发问答': function(event){
$(this).trigger('cb-ui.hide');
$(this).find('[data-cb-ui-class="content"]').animate({
height: 'hide' // happening simultaneously to the animation of 'cb-ui.hide'
// expected to happen in tandem; one after the other
}, 1000);
},
'cb-ui.update': function(event, html){
// none of this is working as expected; the expected being, the 'cb-ui.hide'
// event is triggered (thus fading the [...-content] out) the HTML content is
// updated, then the [...-content] is faded back in from 'cb-ui.show'
// instead its just a mess that results in it fading out
$(this).trigger('cb-ui.hide');
$(this).find('[data-cb-ui-class="content"]').html(html);
$(this).trigger('cb-ui-show');
}
});
$('#foo').trigger('cb-ui.update', ['<p>Hello world!</p>']); // #foo is bound
This example animation should take ~2 seconds, but appears to be taking 1; both animations are occurring simultaneous to each other, rather than in logical order.
Not sure if I understand your question right, but does this make sense?
You can just pass another function to be run after the animation is done.
'cb-ui.hide': function(event, callback){
$('.lol').fadeTo(0,function() {
// fire callback
})
},
'cb-ui.close': function(event){
cb-ui.hide(e,function() {
// other stuff
});
},
