Calling PowerFX functions from HTMLText hyperlink

Posted on by MCrawley2

We want to create a hyperlink in our CanvasApps that directs the user "Back" by calling the PowerFX Back() function but I cannnot find a way to do this.

I'm aware that I can call window.history.back() in a PCF but that's a browser-wide back, which will take the user out of the CanvasApp.

Right now we've coded it as a label with an onSelect but with the limitations we're unable to make it look like a hyperlink including the hover and mouse cursor. It also does not work the same way with Screen Readers as a regular hyperlink would, as screenreaders see them as buttons rather than links.

Ideally what i'd like is a way to interface with PowerFX in some way, eg.

HtmlText.Text = "<a href='App.Back()'>Go Back</a>"

Alternatively, is there is a way to call PowerFX functions from my PCF (perhaps via the context object) then that would also sort my issue.

Does anyone have any ideas?

Thanks.

Hi
@MCrawley2

Do you wanna put the Back(), on your HTMLTEXT?

So try this:

HtmlText.Text = "<a href= " & App.Back() & ">Go Back</a>"

Unfortunately this is invalid syntax.

Try this, on "OnSelect", put this code:

HtmlText.Text = "<a href= " & Back() & ">Go Back</a>"

Have you tested these suggestions? They're clearly wrong just from eyeballing them.

In your previous example you've suggested changing the text of the HTMLText on click of the HTMLText.

This isn't what I'm after and also wouldn't work because Back() doesn't return a type of string.
