How to write function that filters a dictionary when given a key/value pair in Javascript?-CodePudding

I have a dictionary called teamData

var teamData = {
     app: {
      sortCol:"name",
      sortDir:"asc"
     },
     data: [
       {
         id: 1,
         name:"Raptors",
         coachId: 1,
         coachFirst: "Ken",
         coachLast: "jenson",
         coachPhone: "801-333-4444",
         coachEmail: "[email protected]",
         coachLicenseLevel: 1,
         league: 1,
         division: 1
       },
        {
         id: 2,
         name:"Killer Bunnies",
         coachId: 2,
         coachFirst: "Peter",
         coachLast: "Rabbit",
         coachPhone: "801-333-4444",
         coachEmail: "[email protected]",
         coachLicenseLevel: 1,
         league: 1,
         division: 2
       },
       {
         id: 3,
         name:"Thunderbirds",
         coachId: 3,
         coachFirst: "Harry",
         coachLast: "DirtyDog",
         coachPhone: "801-333-4444",
         coachEmail: "[email protected]",
         coachLicenseLevel: 2,
         league: 1,
         division: 2
       }
     ]
     
   }

I'm trying to write a function that takes a key/value object and returns a filtered dictionary. So if the function is

let teams = filter({coachLicenseLevel:1});

then the expected result is to return a filtered dictionary with only two elements that have that key/value pair

Here is the function I have so far, but I'm stuck on how to get the key object.

filter(filterObj) {
        const v = Object.values(filterObj);
        const k = Object.keys(filterObj);
        
        const res = teamData.filter(({???}) => v.includes(???));
    }

any help would be appreciated.

If you want to filter only the data array, you could do something like this:

 function filterArrayByParamAndValue(arr, itemParam, value) {
  return arr.filter(item => item.itemParam === value)

}

And in your code just replace the data property, if

let teamData = {
....,
data: [...filterArrayByParamAndValue(teamData.data, coachLicenseLevel, 1)],
....
}

Of course you should also add all necessary checks in the filter function, or even add an object property to check for and pass the whole object.

CodePudding user response：

Instead of passing an object, you may consider using the filter function with your custom filter logic. Here is an example for your specific case:

let teams = teamData.data.filter(item => item.coachLicenseLevel == 1)
