Check if event is triggered by a human

rated 0 times [ 48] [ 5] / answers: 1 / hits: 72632 / 13 Years ago, thu, july 14, 2011, 12:00:00

I have a handler attached to an event and I would like it to execute only if it is triggered by a human, and not by a trigger() method. How do I tell the difference?

For example,

$('.checkbox').change(function(e){

  if (e.isHuman())

  {

    alert ('human');

  }

});



$('.checkbox').trigger('change'); //doesn't alert

You can check e.originalEvent: if it's defined the click is human:

Look at the fiddle http://jsfiddle.net/Uf8Wv/

$('.checkbox').change(function(e){

  if (e.originalEvent !== undefined)

  {

    alert ('human');

  }

});

my example in the fiddle:

<input type='checkbox' id='try' >try

<button id='click'>Click</button>



$(#try).click(function(event) {

    if (event.originalEvent === undefined) {

        alert('not human')

    } else {

        alert(' human');

    }





});



$('#click').click(function(event) {

    $(#try).click();

});
