jQuery: textbox keyup firing twice

Question

I\'m having a textbox and assigned the following function (it\'s the only function assigned):

txt.bind(\"keyup\",function(event){
    if(event.keyCode==13)
          


        

Answer 1

I had a similar problem
found that object with assigned keyup function was inside another object
first was div second was input
found that keyup was assigned to input and to a div with this input

Answer 2

Here's my workaround for the same issue:

$('input').live('keyup keydown', function(e) {
    var thisKey = e.keyCode ? e.keyCode : e.which;
    if (thisKey == 13) {
        e.preventDefault();
        e.stopPropagation();
        if (e.type == 'keyup') {
            $(this).closest('form').submit();   
        }
    }
});
