            console.log($scope.formData);
            //此处可以进行逻辑处理
            if($scope.registerForm.$invalid){
                alert('请检查您的信息');
            }else{
                alert('提交成功');
            }
        }
    })
    .directive('compare',function () {//定义一个指令
        var object = {};
        object.strict = 'AE';//可以通过元素名和属性名来调用指令
        object.scope = {
            orgText:'=compare'//原始值
        }
        object.require = 'ngModel';
        object.link = function (sco,elem,attr,con) {
            con.$validators.compare = function (v) {
                return v == sco.orgText;
            }
            sco.$watch('orgText',function () {
                con.$validate();
            });
        }
        return object;
