angular js adding two numbers issue
angularjs, javascript
Solution
If that is indeed the case then what is happening is the values that are being passed in for x and y are being treated as strings and concatenated. What you should do is convert them to numbers using `parseInt`
return parseInt($scope.x) + parseInt($scope.y);
or if you prefer brevity
return $scope.x*1 + $scope.y*1;
Problem
I have this code using angular js: ``` <!DOCTYPE html > <html> <head> <title>Untitled Page</title> <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.5/angular.min.js"></script> <script type="text/javascript"> function TodoCtrl($scope) { $scope.total = function () { return $scope.x + $scope.y; }; } </script> </head> <body> <div ng-app> <h2>Calculate</h2> <div ng-controller="TodoCtrl"> <form> <li>Number 1: <input type="text" ng-model="x" /> </li> <li>Number 2: <input type="text" ng-model="y" /> </li> <li>Total <input type="text" value="{{total()}}"/></li> </form> </div> </div> </body> </html> ``` I am able to do multiplication, division and subtraction but for addition, the code just concatenates the x and y values (i.e. if x = 3 and y = 4, the total is 34 instead of being 7) What am I doing wrong?
