PINK program help

Hello, How do I get the PINK variable <NB_var01> into a JavaScript variable? I'm sure its simple but I have little experience in programming in HTML or JavaScript.
I've tried the following without success:

1. var·myvalue = document.getElementsByName('NB_var01').value; //undefined

2. window.status = <NB_var01>;· //errors out

Thanks, any help will be appreciated.

Paul,

I have contacted the developer of the firmware to see if this is supported and how. I will post what I find. Take care.

Problem solved! I put the first·five·<Nb_var0x> variables into a HTML Table. From there I could manipulate the variables using the ID of the table and the 'innerHTLM' javascript statement. Works like a charm! Thanks for your help Chris. Now on to the BS2 side of the·programs.

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<script type="text/javascript">
function load()
  {
  var myVal=document.getElementById('myTable').cells
  alert(myVal[noparse][[/noparse]2].innerHTML)              //shows Nb_var02 value
  }
</script>
</head>
<body onload="load()">
<table id="myTable" border="0"  width="10px">
  <tr><!-- Row 1 -->
     <td><Nb_var00></td>
     <td><Nb_var01></td>
     <td><Nb_var02></td>
     <td><Nb_var03></td>
     <td><Nb_var04></td>
  </tr>
</table>
</body>
</html>

Paul,

I decided to do a little playing around myself since one of my test applications is a remote security station. In order for it to work I need the web page to refresh every 5 seconds (very easy to do) and update the information on the page. But more importantly I need to detect when a variable is set to a certain value and cause the page to redirect. I am doing this with JavaScript and this required me to figure out how to get the variable into a JS variable. Please see the attached snippet from my PINK test page. I hope this helps someone out. Take care.

<script type="text/javascript">
var d="<Nb_var00>"
document.writeln(d)
if (d==="SEARCH") 
{
window.location = "[url=http://www.google.com/]http://www.google.com/[/url]"
}
</script>

The above example jumps to Google when the variable <Nb_var00> changes to the word SEARCH. ·Note that this is exactly what I am using but it should get the point across.· Note also that you don't need the document.writeln section...I was using that to debug the variable information.

I see what you did there. Quoted the variable. Nice. A lot easier than building tables. Thanks for the update.

Paul,

Doing it that way let’s you bring it right into the JavaScript variable…Nice and easy. Take care.
