想用angular做一个自动加法器，代码如下


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

此代码只是但单纯地把字符串连起来了，想用parseInt(add1)+parseInt(add2)但没用，不知道angular有什么方法把字符转为数值。

你可以在$scope中加入对应的函数


 $scope.parseInt = parseInt;

然后可以使用


 parseInt(add1) + parseInt(add2)
