How to call a function once after change()
event complete?
for example, something like this: ( I know jQuery Doesn't have callback method as default )
$('#element').change( function(){
// do something on change
// $('#milestonesSelect').multiselect({ minWidth: 120 , height : '200px' ,selectedList: 4 }).multiselectfilter();
// some animation calls ...
// ...
}, function(){
// do something after complete
alert('another codes has completed when i called');
}
);
Is it possible to call a single callback after all the codes on change method done, except call a complete callback for every functions on it?
I need to do something after the change event has completed
Shall I need to set order to methods in change handler?
You can probably make use of event bubbling and register a callback in the document
.
$(document).on('change', '#element', function(){
console.log('after all callbacks')
});

I just spent some time exploring this myself, and decided to submit my answer to this question as well. This is not utilizing any of jQuery's deferred methods, which might be a better approach. I haven't explored them enough to have an opinion on the matter.
$("#element").change(function() {
handler().after(callBack($("#element").val()));
}
function handler() {
alert("Event handler");
}
function callBack(foo) {
alert(foo);
}

If I understand your question correctly, this will execute code only one time after a change event is fired:
var changed = false;
$('#element').on('change', function() {
if ( !changed ) {
// do something on change
changed = true;
}
}
});
