I want to use enter key to read text box content in asp.net using jquery. I have used the following code to read "id" from the textbox that is being generated runtime:

function showkey(id) {

var keycode = (event.keyCode ? event.keyCode : event.which);
if (keycode == 13) {
alert('You pressed enter key');
}

}


This code is running in chrome and IE but not in firefox.
Please suggest any solution
