Hello,

I'm trying to automatically get the "this.window.name" function to populate in a parameter in my fex. At the moment, all I am able to do is get this to work by calling the variable via onclick. My problem is separated into two items:

1. How do I get javascript to run onload within a .fex?
2. How do I pass the variable set in javascript back to an & variable that the .fex can read?

Here's the code I'm working with so far.

 TABLE FILE CAR
HEADING
"CLICK HERE"
PRINT CAR NOPRINT
WHERE RECORDLIMIT EQ 1
ON TABLE SET PAGE NOLEAD
ON TABLE SET STYLE *
TYPE=HEADING,JAVASCRIPT=SAVEDAT(),$
ENDSTYLE
END
-RUN
-HTMLFORM BEGIN
<html>
<script language="javascript">
function SAVEDAT()
{
var usrid=parent.MyHTMLParmsPage = this.window.name;

alert(usrid);
}
</script>
</html>
-HTMLFORM END


Thanks in Advance!!

There are so many ways to do this.

Simplest (not knowing what you are trying to do) would be to move the HTML to before the report and remove the function container, just run the js.

Hey Waz,

Thank you very much for your response. so if I just put this at the beginning of the report, it looks like nothing runs. Am I doing something wrong? Do I need to use a different function?

What function would I use to pass the var usrid to something WebFOCUS could read?

-HTMLFORM BEGIN
<html>
<script language="javascript">
function SAVEDAT()
{
var usrid=parent.MyHTMLParmsPage = this.window.name;

alert(usrid);
}
</script>
</html>
-HTMLFORM END


Thanks in advance!

Thank you Waz, didn’t see your point about removing the function earlier. How about reading the parameter in the .fex in WebFOCUS? Is there a function that needs to happen? I know there’s some html ibi.amp thing that you put in the code.

Is there a better way to read the current portal page other than this.window.name btw?

Thank you for your help.

Here is where is get tricky.

There are possibly other ways to do it, but my suggestion for simplicity sake is to call your fex with the parameter from the HTML page, passing the name.

Something like this.

-HTMLFORM BEGIN
<html>
<script language="javascript">
window.location = '/ibi_apps//run.bip?BIP_REQUEST_TYPE=BIP_LAUNCH&|BIP_folder={IBFS Location}&|BIP_item={fexname}&|PAGENAME='+this.window.name ;
</script>
</html>
-HTMLFORM END


The fex will get the window name in the variable &PAGENAME

For what it's worth, language="javascript" is not a valid attribute for a script element. The proper attribute is a JavaScript MIME type like this: 
 <script type="text/javascript">


With that said, the HTML5 specification urges authors to omit the attribute rather than provide a redundant MIME type. So that means that all you need is <script> and you're good to go.

Using Waz's suggestion, you could also use an iframe by passing the variable in the uri of the iframe src, and not have to redirect the html page 
  
-HTMLFORM BEGIN NOEVAL
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
    <style>
        #report1{
            width:100vw;
            height:100vh;
        }
    </style>
</head>
<body>
    <iframe src="" frameborder="0" id="report1"></iframe>
    <script>
        const path = `/ibi_apps/run/ibfs`;
        const ibfs_path = `IBFS:/WFC/Repository/domain/fileNmae.fex`;
        const usrid = parent.MyHTMLParmsPage = this.window.name;
        const uri = `${path}?IBFS_path=${ibfs_path}&usrid=${usrid}`
        document.querySelector('#report1').src = uri;
    </script>
</body>
</html>
-HTMLFORM END
