ERROR: jQuery.fn.live() is deprecated

We are having a problem with javascript because of this plugin and jQuery.fn.live()

field-validation.js

//capture any keystroke in a validation field
jQuery(‘.validatefield’).live(‘keyup’, function() {
fieldVal = jQuery(this).val();
fieldKey = jQuery(this).attr(‘name’);
clearTimeout(timeoutID);
timeoutID = setTimeout(‘processKey(fieldVal,fieldKey)’, 500);
});
