My code is as follows :
let filters = [
{name: "MAKE", values:
[
{
Volkswagen: {active: true, make: "Volkswagen"},
Skoda: {active: true, make: "Skoda"}
}
]
}
]
function getFilterValues(){
return filters.filter(f => {
if(f.name == "MAKE"){
return f.values.filter(i => {
Object.keys(i).map(key => {
return key;
});
});
}
});
}
var div = document.getElementById('output');
div.innerHTML = getFilterValues();
I want to loop through filters to get the object keys.
Thus the result that I want is, in this case Volkswagen, Skoda . But my function getFilterValues doesn't return what I want.
Here is jsfiddle .
Any advice?
You can use Object.keys()
to get the list of keys.
var filters = [{ name: "MAKE", values: [{ Volkswagen: { active: true, make: "Volkswagen" }, Skoda: { active: true, make: "Skoda" } }] }]; for (i = 0; i < filters.length; i++) { if (typeof filters[i].values == "object") { console.log(Object.keys(filters[i].values[0])); } }
The main problem is with the filter function. You want map
since with filter you return true/false whether the element should be included in the resulting code. Check out this diff: https://www.diffchecker.com/CX6hOoxo
This works: https://jsfiddle.net/o93Lm0rc/101/
let filters = [
{name: "MAKE", values:
[
{
Volkswagen: {active: true, make: "Volkswagen"},
Skoda: {active: true, make: "Skoda"}
}
]
}
]
function getFilterValues(){
return filters.map(f => {
if(f.name == "MAKE"){
return f.values.map(i => {
return Object.keys(i).map(key => {
return key;
});
});
}
});
}
var div = document.getElementById('output');
div.innerHTML = getFilterValues();
