hide a html table IF form text box value is null

do i replace HideNullParentTable with my table name?

no that's a javascript funtion you ar ecalling.  the table is found my using the parentNode call of the text box id you have passed.

so because the text box exists within a table, the table it exists within is called the parentnode?

it is eventually a parent node.  the first parent node would be the td, then tr, then table.  It cycles through until it finds the first parent table node.  

I'm heading out of the office in a bit and I have tomorrow off.  If I get time at home I'll respond, but no promises.  Sorry...

okay this is my javascript:


<script type="text/javascript" language="javascript">
function HideNullParentTable(myID)
{
 myElement = document.getElementById(myID);
 if (!myElement.value)
 {
   myParent = myElement.parentNode;
   while(myParent.nodeName!='table')
   {
     myParent = myParent.parentNode;
   }
   myParent.style.display = 'none';
 }
}

function RemoveEmptyFields()
{
 HideNullParentTable('_1_1_22_1_Name');
 HideNullParentTable('_1_1_25_1_Name');
 HideNullParentTable('_1_1_28_1_Name');
 HideNullParentTable('_1_1_31_1_Name');
 HideNullParentTable('_1_1_34_1_Name');
 HideNullParentTable('_1_1_12_1_Name');
 HideNullParentTable('_1_1_16_1_Name');
 HideNullParentTable('_1_1_20_1_Name');
 HideNullParentTable('_1_1_37_1_Name');
 HideNullParentTable('_1_1_42_1_Name');
 HideNullParentTable('_1_1_46_1_Name');
 HideNullParentTable('_1_1_50_1_Name');
 HideNullParentTable('_1_1_54_1_Name');
}
</script>


this is my button:

<input name="RemoveApprovers" type="button" value="Remove Extra Approvers" onclick="RemoveEmptyFields();">


no success.  any ideas?

here is a table that i'd like to hide > it contains text box _1_1_28_1_Name
i'm providing this so you get an idea of what's contained within the table i'd like to hide

i need to find empty text boxes and hide the table which the text box exists

Hey, sorry about not being able to help out yesterday...

So is anything happening when you push the button?

hey no worries, hope you enjoyed your day off!

nothing is happening when i push the button....

and in fact i would later like to talk about performing this function on page load - is that possible?

oops, sorry, change this line in the javascript:

while(myParent.nodeName!='TABLE')

javascript pulls the tag name as upper case.  :(  Sorry.

w00t! w00t!

you my friend are amazing.

so what if i wanted to do this onPageLoad?

think it would work?

yes, just add this to your body tag:

<body onload="RemoveEmptyFields()">

hmm that doesnt seem to work:

<BODY Class="pageBody" onload="RemoveEmptyFields()">

really?  Hmmm.  OK try to put this at the bottom of your page inside your body section.

<script type="text/javascript">
RemoveEmptyFields()
</script>

</body>

HAHAHAHA its working

okay, standby - i have to test within my environment


hey, where do you live?  you looking for an opportunity?

lol, opportunity for what?  I'm in Flagstaff, AZ...

i work for a very successful consulting firm in dallas texas -  your skills are needed

we are looking for a developer

what about contract work, you do any?

Heh, definitely not interested in relocating to Dallas.  I have a full time job, but I might be willing to contract out some work if relocating isn't required.

relocating would not be required - every now and then we have a project which calls for some minor development work - you seem perfect.  can you email me ?  i will not ask any technical questions - its strictly for any upcoming dev work that you may be interested in
