Javascript in AbstractPortalContent

Posted on Jan 25, 2005 at 02:52 PM 24 Views

Hi all,

I have a value in a javascript variable and I want to pass it in new java variable declared in the AbstractPortalContent.

It's possible ?

This is my code:

myPageContext.addRawText("<script language='JavaScript'>"+

"var array =window.opener.htmlb_formid'_htmlbElements';"

"var arr = window.opener[array];" +

"var comp = arr['id_component'];" +

"var valore = window.opener[comp].getValue();" +

"</script>");

String my_valore = valore;

Some can help me?

Thanks in advance

Stefano

    Hi Stefano,

    I think I don't understand completely...

    You don't want to do it all at once within the same method, do you? (Because this doesn't make any sense for the JS part is evaluated at Client Side runtime, some ages after the Java method has been processed.)

    If you want to return this value to the AbstractPortalComponent later on, you could just pass it as a parameter and on Java Side read it from servlet request.

    Hope it helps

      Hi Stefano,

      still I don't know your application cycle: you create the HTMLB/JS part and then - how do you come back to the server?

      If by a click on a link or so (so at least "manually"), just pass the value as a parameter to the link (by + "?name=" + value).

      If you return to server side by normal HTMLB events, you cannot pass the parameter this way. For this, you could create a hidden field and set the value by JS into this field and ask the field from server side by standard means.

      Hope it helps

    Hi Stefano,

    I too have also found this issue. It is not possible to use the addRawText method to add this information. My requirement was to add in meta tags by using the addRawText method but after raising a support call with SAP they said it was not possible. However, we did find a way to add in css or javascript declaration by adding this information into the includes. Then you can use context.writeHeadIncludes() which then becomes part of the context.

    I hope this helps.

      Hi Stefano,

      if you press the button, the event you use for opening the new window I expect to be the client side event? If yes, than you call your AbstractPortalComponent by URL, and then - just pass the parameter as a parameter!? Still having problems to realize the problem... hm...

      Hope it helps
