Loop through an two arrays simultaneously and pass a first element of each array to the function at a time using angular js [new to angular]

Question

vm.array1.push(content1);
vm.array2.push(content2);

I have a above two arrays with a data of objects pushed at each time and the data modal of each array looks like this

vm.array1=[object1,object2,object3]
vm.array2=[object1,object2,object3]

I need to pass only object of first element of array1 with the object of first element of array2 to the function.

vm.save(a,b){
//save functionality success by calling API
}

variables a,b should contain only the first elements of both the array simultaneously followed by second elements then third...

How can i pass only objects but not arrays to the function using angularJS?

Assuming they have the same length, loop over one of the arrays and just pass the items at the corresponding indexes. — Evan Trimboli

I'm guessing array1 and array2 are of same length. This should work.

var vm = {
  save: function(a, b) {
    console.log(a, b)
  }
};
vm.array1 = [{
  id: 1
}, {
  id: 2
}, {
  id: 3
}];
vm.array2 = [{
  id: 4
}, {
  id: 5
}, {
  id: 6
}];

vm.array1.forEach(function(a1, i) {
  vm.save(a1, vm.array2[i]);
});

At the simplest you can do following. (This solution will modify your arrays)

do{
   vm.save(vm.array1.shift(), vm.array2.shift()){
   //save functionality success by calling API
   }
}while(vm.array1.length>0)

Plz check may this will be work:-

for(var i=0;i<=vm.array1.length;i++)
{
    for(var j=0;j<=vm.array2.length;j++)
    {
        if(i==j)
        vm.save(vm.array1[i].content1,vm.array2[j].content2){
        //save functionality success by calling API
        }
    }
}

Isn't this very inefficient as you could only loop j^i times instead of i times.
