How to edit rows from a filtered API instance

How to edit rows from a filtered API instance

Hi, I have a requirement for users to be able to select multiple rows and click a button to modify a specific column for each selected row- but only if a particular condition is met within the row.

To do this I'm simply filtering the selected rows with a custom validation function. The filtering is working as filteredRows contains only the rows that should be edited.

Here's an example that shows the logic I'm using currently.

setSelectedColumn(datatable, value) {
    const rowSelector = datatable.rows({ selected: true });
    const filteredRows = rowSelector.filter((row) =>
      this.customValidationFunction(row)
    );

    editor.edit(filteredRows, false).val("status", value).submit();
  }

The problem is that filteredRows doesn't appear to be the correct type for editor.edit() to process it.

I've tried getting the nodes/indexes of the filteredRows from the filteredRows object, but when I do filteredRows.rows() it returns all the rows for the current page- not just the filtered rows. I'm unsure how to select only the filteredRows from the result set itself in such a way that I can get their indexes/nodes.

How can I get the indexes/nodes from filteredRows so that editor.edit() can process it?

    The filter() API returns just the data from the rows matching the condition. This won't work for edit() API. Instead use the row-selector as a function to match the rows you want to edit.

    var filteredRows = datatable
        .rows( function ( idx, data, node ) {
            return data.first_name.charAt(0) === 'A' ?
                true : false;
        }, 
        { selected: true }
     );
    

    To return the selected rows that match the condition. Replace the function with your customValidationFunction() function.

    I had no idea you could pass in a function as a row-selector. That is extremely useful. Thanks so much!
