setFilter( )

Sets the dataset filter.

setFilter() filters out items that don't match the filter criteria.

A filter object is created by calling filter() on wixData and chaining one or more of the following Wix Data filter functions.

• and: See note below.
• between
• contains
• endsWith
• eq
• ge
• gt
• hasAll
• hasSome
• isEmpty
• isNotEmpty
• le
• lt
• ne
• not: See note below.
• or: See note below.
• startsWith

Setting a dataset's filter overrides existing filters that were previously set using setFilter() or using the Dataset Settings panel in the Editor.

To clear a dataset's current filter, call setFilter() and pass it an empty filter. You create an empty filter by calling the filter() function without chaining any of the additional filter functions mentioned above.

Calling setFilter() on a write-only dataset causes an error.

You will need to import wix-data in order to create a WixDataFilter object.
