passing data btwn asp page and javascript include

Justine · August 11th, 2004, 01:51 PM

Hi :)

I have a dilemma. I have an asp page with a javascript include file that creates a dropdown menu. I want to pass my ldap userid variable from the asp to the javascript file without turning off anonymous user access on the folder. Also, company policy doesn't allow the use of cookies.

So, I tried to post the variable in a form. And retrieve it in the javascript page. But I'm guessing the fact that the javascript being an include file in the asp is giving me problems. So here's what I have so far.

home_dev.asp

   <form name="frmPassVar" method="POST">
      <input type="hidden" name="userid" value="<%=session
        "userid")%>">
   </form>

menu_single_dev.asp

   var userid = document.frmPassVar.userid.value

   oCMenu.makeMenu('sub116','top1','% PR
   Report','/users/nantob/percent_pred1/percentpred.asp?userid=' &
   userid)

I'm getting 'is null or is not an object' error. Is this concept wrong? Or is it my syntax. Any suggestions you might have would be appreciated!

Hello,
When are you passing userid to the function (After form is displayed?)

Or if you pass this value from the javascript code written head tag?
If you write in head tag, form is not displayed nad cannot identify the object(i assume that you want to pass this variable on current form load). If you are calling that function from any event procedure, why the need of asp file to have that function and in javascript? Seperate that file as .js file and include using

<script language="javascript" src="menu_single_div.js">
//your coding
</script>

If this is not, make it clear wat you are doing.

Hi Justine,

Firstly, you need to use "+" to concatenate, not "&", so this line...

Code:

oCMenu.makeMenu('sub116','top1','% PR  Report','/users/nantob/percent_pred1/percentpred.asp?userid=' &   userid)

Should be...

Code:

oCMenu.makeMenu('sub116','top1','% PR  Report','/users/nantob/percent_pred1/percentpred.asp?userid=' +   userid)

I think you may be executing the code in your menu file before the page has finished building & the field in the form is therefore not yet available.

If you place your menu initialization code in a function & call that function from the body onload event, all should be ok.

HTH,

Chris

Thanks for the replies!

ChrisScott I think what you've suggested makes more sense to me so here's what I'm trying.
I fixed the + concatenation issue, silly mistake. And I've been playing with creating a function in asp or in asp that includes the javascript file but I'm having trouble making it work.

My funtion call is in the body tag.
<body onload="getMenu()">

And the function I'm trying to write is in the head section. I'm not sure how to write it properly. I've tried asp and javascript functions but it's not working.

<%
function getMenu(){
  <script language="Javascript" source="menu_single_dev.asp"></script>
}
%>

The form that posts the userid is still in the body.

<form name="frmPassVar" method="POST">
    <input type="hidden" name="userid" value="<%=session("userid")%>">
</form>

<script>
  document.frmPassVar.submit();
</script>

I'm pretty sure my function is just plain wrong but I'm not sure what to do instead.

Thanks again.

ChrisScott · August 13th, 2004, 11:27 AM

Hi Justine,

change the content of your menu_single_dev.asp to...

Code:

function getMenu(){
    var userid = document.frmPassVar.userid.value;
    oCMenu.makeMenu('sub116','top1','% PR Report','/users/nantob/percent_pred1/percentpred.asp?userid=' + userid);
}

and in your home_dev.asp...

Code:

<script language="javascript" src="menu_single_dev.asp"></script>

n.b. src, not source

your onload call looks fine

HTH,

Chris

Justine · August 13th, 2004, 04:29 PM

Well all of the code elements are there but I'm getting an invalid syntax error. And it's not consistent with anything in particular.

So, first of all I used just the include file code without trying to pass data. Trying to test each bit individually. But I get the invalid syntax error.

So the only additional code I have on the page is the following. I tried it in the header, in place of the original code. But no luck.

<script language="JavaScript" src="menu_single_dev.asp"></script>

I appreciate all your help!

ChrisScott · August 16th, 2004, 03:07 AM

Hi Justine,

Can you post the whole of your home_dev.asp & menu_single_dev.asp files (preferably as the browser receives it), please?

Cheers,

Chris

Now we are ready for the properties of each level. For those of that have used the old
coolmenus for coolframemenu I will try and explain how this works like this:
level[0] = top items
level[1] = sub items
level[2] = sub2 items
level[3] = sub3 items and so on....
All menus will inherit the properties, and all properties does only HAVE to be spesifed on the top level.
If a level doesn't have on property spesified it will look for it on the last level that was spesified,
if it still doesn't exist it will get the properties from level[0]

Which means that if you set the background color on level[0] to "black" and doesn't spesify any more levels or doesn't
spesify the background color on the last level you spesified ALL menus will get the color from level[0]

Did that make sense at all? This can be a little hard to understand, look at the different examples on my site
and play with and I am sure you'll get what I mean.

Hi Justine,

When you link to a javascript file

Code:

<script language="JavaScript" src="menu_single_dev.asp"></script>

the file you link to should only contain javascript, so you need to lose all those unwanted html tags etc (you could also change the file to a .js extension to help caching if you want).

you can't add (without dynamically writing them) any further script files within the linked file either, so the script block

Code:

<script language="JavaScript1.2" src="/08/beth/08_site/coolmenus3.js">
/*****************************************************************************

******************************************************************************/
</script>

needs to be moved to your HOME_DEV.ASP page

I'm also unsure what the block

Code:

<script>
<!--
  document.frmPassVar.submit();
-->
</script>

is there for, but at present it just causes the page to constantly submit, so probably worth commenting out.

Let us know how you get on.

Good luck,

Chris
