Popup media group from Arcade Array

ADClark — Wed, 02 Nov 2022 19:45:32 GMT

I am trying to determine how to create a popup Media Group of images from an Arcade array of image URLs. The images are not stored as attachments, but as a list of URLs in a field. I have been able to successfully parse the list and display the images using rich text with HTML tags, but I would prefer to have the look of a media group (i.e. with forward/backward arrows).

I know that JSON for a media group is generally of the following format:

{ "type": "media", "description": "", "mediaInfos": [ { "altText": "", "caption": "", "title": "", "type": "", "value": { "linkURL": "", "sourceURL": "" } }, { "altText": "", "caption": "", "title": "", "type": "", "value": { "linkURL": "", "sourceURL": "" } }.......] }

Would the best approach be to simply build a JSON representation for the media group and then return the results of calling "FromJSON" on it? (https://developers.arcgis.com/arcade/function-reference/data_functions/#fromjson) Would that actually work to display a media group in the popup? Thanks in advance for any input or ideas.

I ended up coming up with the following solution, posting in case it might help anyone else:

var contents = Split($feature.photourls, ',', -1, TRUE) var imageArray = [] if (Count(contents) > 0) { for (var i in contents) { var value = Dictionary("sourceURL", contents[i]) var image = Dictionary("type", "image","value", value) Push(imageArray, image) } var imageDict = Dictionary("type","media","description", "Media Group Photos", "mediaInfos",imageArray) return imageDict } else { return Dictionary("type","text","text","No Photos to Display") }
