Are event handlers executed synchronously or asynchronously in JavaScript? Here is JS bin which is showing that event handler is executed synchronously.
Code:
$('#toclick').bind('custom', function() {
for (var i=0; i<100000; i++) {}
console.log('Inside click handler');
});
$('#toclick').trigger('custom');
console.log('Outside click handler');
Output:
Inside click handler
Outside click handler
This means if we trigger an event, the code below it won't be executed unless all the event handlers are executed. Am I right ?
That's correct. All event handlers are fired synchronously and in order of binding.
Some event handlers are executed synchonously and others asynchronously. See DOM-Level-3-Events
