javascript - Fire change event although not focused -
is possible bind event handler input field fired, value changes although not focused?
thank you.
from jquery official documentation :
the alter event sent element when value changes. event limited elements, boxes , elements.
so in jquery:
$( "#bar" ).change(function() { alert( "handler .change() called." ); });
you don't have such functionality available in pure javascript. in case could, define function checks value of input
, periodically using setinterval
method (from relvant post):
var foo = document.getelementbyid("bar"); var oldvalue = foo.value; function checkifvaluechanged() { if(foo.value != oldvalue) { //necessary code trigerred on value alter clearinterval(checker); } } //every 500ms check if value changed var checker = setinterval('checkifvaluechanged()', 500);
i hope gets started in right direction.
