I have an array of position and nested user objects like so:
[
position: {
title: Developer,
user: { name: Albert }
},
position: {
title: CEO,
user: { name: Smith }
}
]
How do I get an array of [user, user] with Angularjs?
Assuming this is pseudo-code (as it's missing a few { and } and you'd need variables called Developer, Albert, CEO & Smith - I've fixed these in the working example) you can use Array.map:
var arr = [{
Position0: {
title: Developer,
user: { name: Albert }
},
{
Position1 : {
title: CEO,
user: { name: Smith }
}
}];
var result = arr.map(function(val, idx) {
return val["Position" + idx].user.name;
});
I just tried this code, and works ...
var positions, users;
users = [];
positions = [
{
title: 'Developer',
user: { name: 'Albert' }
},
{
title: 'CEO',
user: { name: 'Smith' }
}
];
angular.forEach(positions, function(position) {
users.push(position.user);
});
console.log(users);
Firstly this thing does not need angularjs.
The way you can do that is using for each loop:
var users = [];
var positions = [{
Position0: {
title: 'Developer',
user: { name: 'Albert' }
},
Position1 : {
title: 'CEO',
user: { name: 'Smith' }
}
}]
for(var i =0; i< positions.length; i++){
for(var j in positions[i]){ //used to loop on object properties
if(positions[i].hasOwnProperty(j)){ //checking if the property is not inherited
if(positions[i][j].user){ //checking if the property exist, then only will push it to array, so that array doesnot have undefined values
users.push(positions[i][j].user);
}
}
}
}
users array will have the users.
Use angular.forEach():
var arr1=[]
var arr=[
position: {
title: Developer,
user: { name: Albert }
},
position: {
title: CEO,
user: { name: Smith }
}
];
angular.forEach(arr,function(value,key){
arr1[key]=value.position.user;
});
console.log(arr1);
angular.forEachwhich polyfills Array.forEach. That could easily have been pertinent to the solution.{and also}. from what I can see it doesn't seem to be an array, instead it sounds like a single object. But if it really is an array of positions it should be like:[{title:'A', user:{}},{title:'B', user:{}}]or at least:[{position:{title:'A', user:{}}}, {position:{title:'B', user:{}}}]
