Alerting the this.id keyword returns undefined Javascript

rated 0 times [ 3] [ 3] / answers: 1 / hits: 15433 / 11 Years ago, thu, october 10, 2013, 12:00:00

I create the same inputbox a couple of times dynamically. When a user presses enter it calls a function. I then test with this code:

function insertComment(){

  alert($(this).attr('id'));

}

But it keeps returning undefined. Here is the syntax I use to create similiar input boxes:

$(#divToAppend).append(<input id='testID' type = 'text' class = 'formatCSS' style = 'margin-top:12px ; ' placeholder = 'Add Comment' onkeydown='if (event.keyCode == 13) insertComment()'></input>);

Just pass this while calling method :

$(#divToAppend).append(<input id='testID' type = 'text' class = 'formatCSS' style = 'margin-top:12px ; ' placeholder = 'Add Comment' onkeydown='if (event.keyCode == 13) insertComment(this)'></input>);





function insertComment(this)

{ 

alert($(this).attr('id')); 

}
