How to trigger an event in input text after I stop typing/writting?
- by user1386320
I want to trigger event just right after I stop typing (not while typing) characters in my input textbox.
I've tried with:
$('input#username').keypress(function() {
var _this = $(this); // copy of this object for further usage
setTimeout(function() {
$.post('/ajax/fetch', {
type: 'username',
value: _this.val()
}, function(data) {
if(!data.success) {
// continue working
} else {
// throw an error
}
}, 'json');
}, 3000);
});
But this example produces a timeout for every typed character and I get about 20 AJAX requests if I type-in 20 characters.
On this fiddle I demonstrate the same problem with a simple alert instead of an AJAX.
Is there a solution for this or I'm just using a bad approach for this?
