Input cursor position jumps to end with ng-change()

Question

I have an instance where I'm replacing the value of ngModel through ngChange. The cursor jumps to the end of the input field after each change (assuming because I'm assigning the result to the same $scope variable.)
I'd like to know how I can prevent this behavior?

  $scope.compute1 = 0;
  $scope.compute2 = 10;

  $scope.math = function() {
    $scope.compute1 = parseInt($scope.compute1);
    $scope.compute2 = parseInt($scope.compute2);

    $scope.compute1 = parseInt($scope.compute1);
  };

Example of problem: if a user types in 1000. It's fine. But then if they want to go back and change the number to 156000 by just adding the 5 and 6, the 6 would actually be appended to the end: 15006.

Answer 1

The cursor goes to the end because we modify data by using parseInt.

I suggest you to store the caret position before and then when you're done doing things, set it back.
