APEX

I would like to put various information inside form tags
in order to display a message in the status bar (message bar)
at the bottom of the web page when the user is on the field.

The information varies depending on which field the user is on.
In Oracle Web Toolkit (and Cold Fusion) I am able to put javascript in the tag.

onFocus="javascript:window.status='Enter Text (Wildcarding automatically performed)' "
onMouseMove="javascript:window.status='Enter Text (Wildcard automatically performed)' "

How do I do this in Application Express?

Examples:
<select name="clsdDate_range_selection"
onFocus="javascript:window.status='Select Date Range' "
onMouseMove="javascript:window.status='Select Date Range' ">
<option value="" selected>
<option value="On">On
<option value="Before">Before
<option value="After">After
<option value="Between">Between
</select>

<INPUT TYPE="Text" NAME="title" SIZE="40" MAXLENGTH="45"
onFocus="javascript:window.status='Enter Title (Wildcarding automatically performed)' "
onMouseMove="javascript:window.status='Enter Title (Wildcarding automatically performed)' ">

<select name="failure_type" size="1"
onFocus="javascript:window.status='Select Failure Type' "
onMouseMove="javascript:window.status='Select Failure Type' ">
<OPTION VALUE="" selected>Any
<OPTION VALUE="H" >H - HARDWARE
<OPTION VALUE="S" >S - SOFTWARE
<OPTION VALUE="A" >A - ADMIN
</select>
