Return a url based on a feature attribute in pop-up using Arcade?

Hayley — Thu, 01 Dec 2022 22:03:04 GMT

I am trying to embed a URL into my pop-ups for a rubbish collection map.

If the collection week of a boundary is week one, I want the URL to go to the week one page.

If the collection week of a boundary is week two, I want the URL to go to the week two page.

I would like the URL to be embed into the word "here" in the pop-up as seen below:

What expression is needed to pass through the correct URL for each pop-up? I have started with what I have below but am aware URLs need to be formatted in a certain way. Any pointers much appreciated!

if ($feature.Week == "Week 1") { return "https://www.ashburtondc.govt.nz/?a=57072" } if ($feature.Week == "Week 2") { return "https://www.ashburtondc.govt.nz/?a=57073" }

You'll want to add the Arcade as an attribute expression, and then point the hyperlink to that expression. It looks like you're using Map Viewer Classic, so that button is here:

Once you're there, try adding this expression:

var week = $feature.Week decode(week, "Week 1", "https://www.ashburtondc.govt.nz/?a=57072", "Week 2", "https://www.ashburtondc.govt.nz/?a=57073")

Then, with "here" selected in your popup configuration, click Link and enter the name of your attribute expression in brackets, like this:

Click 'Update.'

Hi @wayfaringrob thanks for your help!

I have created that as a new expression however am getting the error "Execution Error: Must have a default value result."

Am I missing something here? Thanks!

Hi again @wayfaringrob, I added the default value to the end of the expression and tested with no error.

var week = $feature.Week decode(week, "Week 1", "https://www.ashburtondc.govt.nz/?a=57072", "Week 2", "https://www.ashburtondc.govt.nz/?a=57073", default)

The pop-up has recognised the word "here" as a hyperlink in the pop-up however it does not navigate to anywhere/can't be clicked. Am I missing something here? Thanks!

I found another way around it, using the expression below:

var calendarone = "https://www.ashburtondc.govt.nz/?a=57072" var calendartwo = "https://www.ashburtondc.govt.nz/?a=57073" if ($feature.Week == 'Week 1') { return calendarone } else { return calendartwo }

Nice! Yeah, the Arcade documentation said the default portion was optional so I'm not sure why it didn't work that way.
