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: "ken.jenson@uvu.edu",
coachLicenseLevel: 1,
league: 1,
division: 1
},
{
id: 2,
name:"Killer Bunnies",
coachId: 2,
coachFirst: "Peter",
coachLast: "Rabbit",
coachPhone: "801-333-4444",
coachEmail: "peter.rabbit@uvu.edu",
coachLicenseLevel: 1,
league: 1,
division: 2
},
{
id: 3,
name:"Thunderbirds",
coachId: 3,
coachFirst: "Harry",
coachLast: "DirtyDog",
coachPhone: "801-333-4444",
coachEmail: "harry.dirty.dog@uvu.edu",
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.
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)
