Lianja.activepage in js

[SpringBox]

Hi guys

As Lianja.activepage does not exist in js/web, what would be the best alternative to Lianja.activepage.id ?

Sure there must be a way to know which page is active in js or should we just use a global memvar?

Thanks in advance

Hi Simon,

I have added that into the Lianja Web Framework in Lianja 6.3.

In the meanwhile as a workaround in your javascript library:

function getActivePage()
{
var page = Lianja.get(Lianja.App.currentpageid);
return page;
};

Thanks Barry

Don't know what we've missed but can't get that to work

Cheers

Try it interactively in the web browser javascript console.

If you can’t get it to work replace Lianja.get() with Lianja.App.getPage() or wait until 6.3 is released.

Hi Barry

Not exactly sure what you meant in last reply so tried them all.


Tried Lianja.App.getPage(); interactively in the browser but

LianjaHtmlClient.js?_v=6.2.1.909-1628931458913:4433 Uncaught TypeError: Cannot read property 'replace' of undefined
at window.Lianja.Application.getPage (LianjaHtmlClient.js?_v=6.2.1.909-1628931458913:4433)
at <anonymous>:1:12

Also tried every version of the syntax we can think of in the js command window but it doesn't recognise the App part. We have tried :

var page = Lianja.App.getPage();

var page = Lianja.get("Lianja.App.getPage");

var page = Lianja.get("Lianja.App").getPage();

var page = Lianja.get("Lianja.App.getPage()");


and even (which have to be wrong)

var page = Lianja.App.getPage("Lianja.App.currentpageid");

var page = Lianja.App.getPage("currentpageid");

but all return false


Any thoughts?

var page = Lianja.App.getPage( Lianja.App.currentpageid );

Hi Barry

When testing interactively in js command window

var page = Lianja.App.getPage( Lianja.App.currentpageid );

returns

Sun Aug 15 14:13:04 2021
**** Lianja JavaScript error ****
Traceback (most recent call last):
TypeError: Result of expression 'Lianja.App' [undefined] is not an object.

and when testing in the VFP command window, returns

Sun Aug 15 14:21:21 2021
**** Lianja error ****
var page = Lianja.App.getPage( Lianja.App.currentpageid )
^
Property/Variable 'APP' not found


and returns undefined when testing interactively in browser.

Lianja does not recognise the App object for some reason.

Not to worry, we have made a memvar based work around for now and it can wait until 6.3

Cheers

Yes. It’s an undocumented workaround in the web browser. Not a desktop workaround.
