hi ...

with:

Expand|Select|Wrap|Line Numbers

Period.attachEvent("onkeyup",fnEscalationPeriod(this));

you make a functioncall of fnEscalationPeriod immediately ... so you get the error ... you want to assign the function to the obj called Period ... ok? so you have to use:

Expand|Select|Wrap|Line Numbers

 
<script type="text/javascript">

    function fnEscalationPeriod(obj) {

        alert(obj.id);

    }
 
    function add_event() {

        var keyup_handler = function(e) {

            var obj = e.srcElement;

            fnEscalationPeriod(obj);

        };
 
        // and later on you have to use

        document.getElementById('test')

            .attachEvent('onkeyup', keyup_handler);

    }

</script>
 
<body onload="add_event();">

    <input id="test" type="text"/>

</body>

kind regards

ps: note - that is IE-specific ... other browsers use addEventListener instead
