Javascript - 从数组中过滤对象

Question

I'm running into an issue where when I pull information into my array "const testOutput", when I go to filter, the filter causes nothing to return. I think the issue is the "serverArray:" that appears within my array. Here's my code now.

 const testOutput = { "serverArray": [{ "machineName": "test1", "status": "ACTIVE", "daysActive": 3, "daysLeft": 117 }, { "machineName": "test2", "status": "ACTIVE", "daysActive": 2, "daysLeft": 118 }, { "machineName": "test3", "status": "ACTIVE", "daysActive": 3, "daysLeft": 117 } ] } console.log(Object.values(testOutput).filter(filtered => filtered.daysActive === 3));

When I take out the "serverArray:" within javascript fiddle online, it filters correctly. So I was curious if there was something I could add to my filter to remove the "serverArray" so that the objects can be filtered. Thanks!

You need to destructure the serverArray array from the testOutput , filter it, and re-assign it. I added an additional property to the testOutput object in order to demonstrate "keeping" other existing properties.

 const testOutput = { "foo": "bar", "serverArray": [{ "machineName": "test1", "status": "ACTIVE", "daysActive": 3, "daysLeft": 117 }, { "machineName": "test2", "status": "ACTIVE", "daysActive": 2, "daysLeft": 118 }, { "machineName": "test3", "status": "ACTIVE", "daysActive": 3, "daysLeft": 117 }] } const { serverArray, ...rest } = testOutput; const filteredOutput = {...rest, serverArray: serverArray.filter(({ daysActive }) => daysActive === 3) }; console.log(filteredOutput);

Replace testOutput To testOutput.serverArray

Try

console.log(Object.values(testOutput.serverArray).filter(filtered => filtered.daysActive == 3));
