I am using setFilter to filter a dataset on a page based on a user action (i.e. click on a cell in a table) and a repeater to display the data from the dataset after filtering.
Sometimes a user will click a cell which will filter out all data in the dataset because there is not currently any data in the collection for that selection. Is there a way to return a message to the user them the there is no data in the collection for that filter action?
Hello truthandlies!
First you’ll want to check if the results received from the promise have a length that are less then 1 or return null, if they do then that means there is no data to show based off of the filters selected
Then you’ll want to expand/show the error message that is collapsed/hidden by default, and maybe set a timeout to hide it again after 3 seconds.
Please post some code so I can help out with the implementation if needed.
General example of how it would look:
EDIT: Wix has a built in query that returns items in a collection that have an empty value for a specific property, Look at: https://www.wix.com/code/reference/wix-data.WixDataFilter.html#isEmpty
