问如何在angularjs中结合字母、数字和特殊类来验证我的密码？

angular.module('loginApp',[])
    .controller('loginController',function($scope){
    $scope.obj={};
    

    $scope.submit=function(){
        if((!/\d/.test($scope.obj.password))){
        alert("password must contain digits");
        }
        if(!/[A-Z]/.test($scope.obj.password)){
        alert("password must contain uppercase letter");
        }
        if(!/[a-z]/.test($scope.obj.password)){
        alert("password must contain lowercase letter");
        }
        if(!/[ !@#$%^&*()_+\-=\[\]{};':"\\|,.<>\/?]/.test($scope.obj.password)){
        alert("password must contain special character");
        }
        console.log( $scope.obj);
    }

    })
