Adding an keyUp-event to form objects

Hello folks,

I've got the issue to add a browser event to some input fields. The challenge I have to face is, that one parameter of my target function is the 'event'-variable and the second one an object.

For a better understanding here some codes:

The HTML object:

<div id="1_dateFieldAdvanced" class="xp set">
    <div id="1_dateFieldAdvanced_label" class="label">Birthday</div>
    <div id="1_dateFieldAdvanced_value" class="value date">
        <input class="day" name="dayOfBirth" value="66" maxlength="2" type="text">
     开发者_C百科   <input class="month" name="monthOfBirth" value="67" maxlength="2" type="text">
    <input class="year" name="yearOfBirth" value="" maxlength="4" type="text">
    </div>
</div>

The source code of target method is like below:

function advancedDateFields(currentFieldAsObject, nextField, currentValueLength, ev){}

Unfortunatly the HTML and the Javascript code is generated automatically, so I'm unable to refactore the code. My question is, how can I pass the key word 'event' and the other parameters? My tries did always fail. :-(

What about

$("input:text","#dateFieldAdvanced_value").bind("keyup", function(e){
    var currentElem = $(this);
    var currentValLength = currentElem.val().length;
});

I am not sure what you meant by next field.

Also you ids are invalid. Id should not start with a number. So I changed 1_dateFieldAdvanced_value to dateFieldAdvanced_value

YOu can call function onkeypress: Example:

function(event) { customMethod(event, obj); }

I hope this helps..

function lookup(inputString) {
        if(inputString.length == 0) {
            // Hide the suggestion box.
            $('#suggestions').hide();
        } else { 
// Show the suggestion box.
            $('#suggestions').show();
}
