How to get the number of filtered rows in ag-Grid?

问题

I have an ag-Grid with filtering option.

How to get the number of filtered rows without using forEachNodeAfterFilter callback?

I want to enable a button only if there is a filtered row, and i don't want to perform a foreach loop in the background every time.

回答1:

gridOptions.api.getModel().rootNode.childrenAfterFilter.length

You should check out what else is available to you under rootNode, there are a few arrays that might be useful to you

回答2:

What you are probably looking for is:

gridOptions.api.getDisplayedRowCount()

The actual number of rows after the filtering event is trivially the number of displayed rows.
