Angular how to edit all elements in an array at ones

Question

i currently have an array of objects i use to generate html checkboxes (ng-repeat). All those objects have an x.checked = true / false attribute. How can i set this x.checked = false for all objects at once?

Right now i use a simple for loop.

for(var i = 0; i < array.length; i++) {
  array[i].checked = false;
}

Does Angular have a faster or shorter way of doing this?

Thanks!

May be you need to use ng-init or loop I guess. plnkr.co/edit/JQnCnmSEAqyj93Sgs9KJ?p=preview — Coder

There is no way to do it per se, no matter how you write it, you will never do it all at once, it will at best be a shorthand for what your wrote above.

They go through the entire list, it's O(n) complexity

Yes , You can use angular.forEach for this, Like so:

angular.forEach(array, function (item) {item.checked = false;}

It's also loop right? But I don't know which is faster, angular.forEach or for

yes, it is also loop. angular.forEach is slower than for.

Or you could use Array.forEach similar syntax to angular.forEach but I think it will be faster.

items.forEach(function (item, index, array) {
  item.checked = false;
});
