Front-end - string conversion problem when using angularjs

Question

I want to use angular to make an automatic adder, the code is as follows

    <input type="text" ng-model="add1">
    <input type="text" ng-model="add2">
    <p>total={{add1+add2}}</p>

This code simply connects strings. I tried to use parseInt(add1) parseInt(add2) but it didn’t work. I don’t know if Angular has any method to convert characters into numerical values.

Answer 1

 <p>total={{add1 * 1 + add2 * 1}}</p>

Answer 2

You can add the corresponding function in $scope

$scope.parseInt = parseInt;

Then you can use it

parseInt(add1) + parseInt(add2)
