Silly little problem

**drpcken** · Oct 19th, 2004, 12:39 PM

I have created a variable in my code, and I have a txtbox name txtHidden1. I want to fill the variable with the value of the txtbox but i dont' think I'm doing it right... Here's what I have now...

Code:

var varDNC
varDNC = txtHidden1.name

Very new to javascript, needed a feature that i couldn't do in VB.net and once this works it will be great!

Thanks guys!

var myVar = document.getElementById('elementID').value

Awesome dude...

But I'm getting an error in my IE that says Object Required when the page loads and the label doesn't show when it should.

Here's my code, appreciate all your help!

Code:

<script language="javascript" type="text/javascript">
function showDNC() {
var varDNC = document.getElementById('Hidden1').value;
}
if (varDNC = 1) 
{
parent.topFrame.document.getElementById('lblDNC').style.visibility="visible"
}
else
{
parent.topFrame.document.getElementById('lblDNC').style.visibility="hidden"
}
</script>

Code:

<script language="javascript" type="text/javascript">
function showDNC() {
var varDNC = document.getElementById('Hidden1').value;
} 
if (varDNC ==  1) 
{
parent.topFrame.document.getElementById('lblDNC').style.visibility="visible"
}
else
{
parent.topFrame.document.getElementById('lblDNC').style.visibility="hidden"
}
</script>

The } marked in red end the function. Are you sure you wanted that?

Also language="javascript" should not be there, it servs no purpose.

Edit: This could also be happening in the bottom frame loads and runs the function before that textbox has loaded up in the top frame. There are ways to sort this out. but first see if it works as it is, to see if we need to fix this.

2nd Edit: I added another equals into the IF statement, you need two equals in JS, unlike ASP. One will set the value equals to the right hand side, two will check to see if the are the same.

The textbox is in the same frame as this code.

And with these changes, I only get the error once, before I was getting it twice. here's the code I updated...

Code:

<script type="text/javascript">
function showDNC() {
var varDNC = document.getElementById('Hidden1').value;

if (varDNC = 1) 
{
parent.topFrame.document.getElementById('lblDNC').style.visibility="visible"
}
else
{
parent.topFrame.document.getElementById('lblDNC').style.visibility="hidden"
}
}
</script>

If it's in the same frame, then you can simplify:
parent.topFrame.document.getElementById('lblDNC').style.visibility
to:
document.getElementById('lblDNC').style.visibility

also, read my second edit. I changed the IF to have two ='s

**drpcken** · Oct 19th, 2004, 02:09 PM

sweet changed the ==

also just to let you know, the only thing in the top frame i'm manipulating in this code is the lblDNC, or the lines

Code:

parent.topFrame.document.getElementById('lblDNC').style.visibility="visible"

and

Code:

parent.topFrame.document.getElementById('lblDNC').style.visibility="hidden"

Everything else, such as the Hidden1 textbox, is in the same frame as the javascript being written.

same object required error

**Acidic** · Oct 19th, 2004, 02:11 PM

The text box does have id="Hidden1" right? not name="Hidden1" or that the case is wrong. Unless that was the error, post me the code for the entire page please. Not including ASP, just the outputted HTML.

Same applies for the element whose visibility you're changing.

**drpcken** · Oct 19th, 2004, 02:19 PM

**Acidic** · Oct 19th, 2004, 02:41 PM

Is that all the HTML? There are no elements with those IDs, that's whats causing the error.

**drpcken** · Oct 19th, 2004, 02:48 PM

I was just showing you the html with the javascript code, and the textbox that i'm pulling the value into my var.

the lblDNC is in the top frame by the way.

What do you mean by elements?

**Acidic** · Oct 19th, 2004, 04:09 PM

by element I mean an HTML element, ie <img> <input> <a> etc.

Since it's in the top frame, please post the HTMl code for that.

**drpcken** · Oct 19th, 2004, 04:13 PM

Ok here's the output html from the top page, but i notice it doesn't have my lblDNC that suppose to be there....

Well, there you go. That's your error. It's changing the visibility of a non-existing element.

**drpcken** · Oct 19th, 2004, 04:27 PM

Code:

<span class="style3" ><asp:Label ID="lblDNC" Text="DO NOT CALL this prospect!" runat="server" /></span>

This is the code from dreamweaver, same file only from the source. The first bit I sent was from the outputted HTML when I view source in IE.

Any ideas?

**Acidic** · Oct 19th, 2004, 04:29 PM

I have no clue as to ASP. Sorry. Why can't you just write that part as normal HTML though? You don't seem to be printing off any ASP variables, so why not just make it normal HTML, not ASP?

edit: that was my 2¹⁰th post.

2nd edit: if this turns out to be an ASP issue, then there is a seperate ASP forum.

**drpcken** · Oct 19th, 2004, 04:34 PM

I think I'm going to have to just dump my frames, and create headers out of all my top frame pages.

Thanks for all your help!

**Acidic** · Oct 19th, 2004, 04:35 PM

Frames are pointeless. CSS can replicate all the effects frames create. Though IE doesn't support position: static; yet.

But this can still work using frames. Just ask in the asp section why the element doesn't appear in the HTML source.
