如何过滤剑道网格（AngularJs）中的对象数组？

Question

I have a Document object like this:

{"id": 1, "annotation": "some text", "signers": [{ "id": 32, "name": "Bob", "address": {"country": "USA"}}, 
{ "id": 44, "name": "Bill", "address": {"country": "Canada"}}]}

Documents are displayed in a Kendo grid, and one of the columns is for signers. How is it possible to filter signers by name (and also by country, but that is less relevant)? How to filter an array of objects?

I've been trying to figure out how to write a custom filter function and do all the filtering on client side, but I haven't been able to figure this out.

You can create a Set of the names or countries to search for and call Set#has in the callback for Array#filter .

 let doc = {"id": 1, "annotation": "some text", "signers": [{ "id": 32, "name": "Bob", "address": {"country": "USA"}}, { "id": 44, "name": "Bill", "address": {"country": "Canada"}}]}; const names = new Set(["Bob", "Joe"]); doc.signers = doc.signers.filter(({name})=>names.has(name)); console.log(doc);
