"Page URL" Check

Ignition

Hello,

is there a way to know if a "Page URL" is active/configured using expressions or scripts? I would need this to enable/disable commands based on whether the reference URL exists or not.

I found a solution that works for Perspective pages using "chromedriver" and "selenium".
Its a little bit tricky but it works.

While you provided a solution, it's not a good one. Use the 1st party provided functions to get the job done. system.perspective.getProjectInfo will provide a list of all page configurations for the project, which sounds like what you're looking for as it contains the configured mounted paths (project URLs).

Ok! it works!

So for that function, it says it works from a Gateway scope but I'm getting this error in the logs calling that function from a timer script.

Caused by: java.lang.IllegalArgumentException: No perspective session attached to this thread.

Could you provide your code?

system.util.getLogger("ProjectInfo").info(str(system.perspective.getProjectInfo()))

Got it. The function returns information about the project being used by a Session. When executed by any non-Perspective context, the function has no idea what project to return data about.

I've reached out to the Documentation team to see about clarifying the docs.

Gotcha. Thank you for updating the documentation team.

The Docs appear to be updated to reflect that Gateway is not a valid scope for this function.

Dear team,

I have one doubt?
In Vision, to find out how long a particular window has been open, there's a 'System.gui.getWindow' function. Is there any similar function to determine how long a particular view has been open in perspective?

14

No, but it's not hard to implement by yourself using now(0).
But what exactly are you trying to do ?

15

I have 10 views in Perspective, and I need to get the value of which view the user opens and how long it has been open. I can use page.props.path in the onStartup script, but that would require doing it individually for each screen. I don't want to do it that way. I need to make it dynamic with one script so that I can know which screen the user is using and for how long.

16

Use a shared docked view. Put the check for page.props.path there.

Thank You! It works
