I have some angular code that I am working on. The goal is to use as little angular 1.x functionality as possible since this will be getting refactored soon.
I am comparing an array
let subscription = [
"Cinemax Subscription",
"Disney Subscription",
"Encore Subscription",
"Epix Subscription",
"HBO Subscription",
"MLB Subscription",
"NBA Subscription",
"NHL Subscription",
"Division"
]
to an array of objects with a key value relationship that houses another array.
let profiles = [
{
name:"1+ Adults in Household",
qualifiers: [
{
name: 'Number of adults in the household'
}
]
},
{
name: '75k',
qualifers: [
{
name: 'Division'
},
{
name: 'Income'
}
]
},
{
name: 'Time Warner',
qualifers: [
{
name: 'Division'
}
]
}
]
I am having a difficult time with the indexes and the looping of this.
let = profilesFiltered = [];
Initially I tried to use a filter and angular.for Each to compare the arrays.
let filteredProfiles = subscription.filter( function (src) {
angular.forEach(profiles, function (key, index) {
if(src === key.qualifiers[index].name) {
profilesFiltered.push(key);
}
})
});
I am seeing inside the if statement that
key.qualifiers[index].name // 'Number of adults in the household'
Starts out correct in comparison to
subscription[0] // however, it will continue to 1 on the first object which isn't there.
I see how it is starting to fail. But I am not sure how to get properly loop through the qualifiers in the **profiles ** array.
The desired result is as those house Division which is the last array item in the index.
profilesFiltered = [
{
name: '75k',
qualifers: [
{
name: 'Division'
},
{
name: 'Income'
}
]
},
{
name: 'Time Warner',
qualifers: [
{
name: 'Division'
}
]
}
]
Any feedback is greatly appreciated at this point.
Thanks
Just filter the profiles, using a combination of filter()
and some()
:
profiles.filter(v => v.qualifiers.some(q => subscription.includes(q.name)));
let subscription = [ "Cinemax Subscription", "Disney Subscription", "Encore Subscription", "Epix Subscription", "HBO Subscription", "MLB Subscription", "NBA Subscription", "NHL Subscription", "Division" ] let profiles = [{ name: "1+ Adults in Household", qualifiers: [{ name: 'Number of adults in the household' }] }, { name: '75k', qualifiers: [{ name: 'Division' }, { name: 'Income' } ] }, { name: 'Time Warner', qualifiers: [{ name: 'Division' }] } ] let res = profiles.filter(v => v.qualifiers.some(q => subscription.includes(q.name))); console.log(res)
Are you looking for something like this, checkout my code
let profiles = [ { name:"1+ Adults in Household", qualifiers: [ { name: 'Number of adults in the household' } ] }, { name: '75k', qualifiers: [ { name: 'Division' }, { name: 'Income' } ] }, { name: 'Time Warner', qualifiers: [ { name: 'Division' } ] } ]; let subscription = [ "Cinemax Subscription", "Disney Subscription", "Encore Subscription", "Epix Subscription", "HBO Subscription", "MLB Subscription", "NBA Subscription", "NHL Subscription", "Division" ]; let profilesFiltered = profiles.filter(function (a) { // first filter all element in the profiles array // check if their qualifiers array is not empty return a.qualifiers.some(function (b) { // filter the qualifiers array by checking the property name // is it muching any element from subscription array return subscription.indexOf(b.name)!==-1; }); }); console.log(profilesFiltered);
Here is a working code for your data structure. It is based on using reduce function. If you need to have no duplicates - answer here .
