angular.js - 同时有angular和jquery插件处理keydown事件

网上下了个jq插件,输入框绑定了click事件,但是我自己写的angular脚本也在同一个输入框上用了ng-keydown。。。我以为是angular的keydown处理函数会执行,结果没效果。。。但是我又不能把插件的click事件处理函数给去掉,因为要用到它的功能。。。不知道怎么处理这种情况

    <body ng-app="myApp" ng-controller="MyController">

    <!--自定义指令: 限制输入框中只能是1到100之间的数值-->
    <input type="text" score>
    <script type='text/javascript' src="angular.js"></script>
    <script type="text/javascript">

    angular.module('myApp',[])

                .directive('score', function () {
                    return {
                        link : function (scope, elements, attrs, controller) {  //在显示之前执行, 只执行一次
                            //得到input
                            //console.log('link()',elements);
                            var input = elements[0]
                            //给input绑定keyup的监听回调函数
                            input.onkeyup = function () {
                                //读取input的value, 判断是否合法
                                var score = input.value.trim()
                                //如果合法, background为white
                                if(score==='' || (score*1>=1&&score*1<=100)) {
                                    input.style.background = 'white'
                                } else {
                                    //否则为red
                                    input.style.background = 'red'
                                }
                            }
                        }
                    }
                })
                .controller('MyController', function($scope){
    
                });
                

    </script>
    </body>
    </html>

    The keyup event I just wrote today, keydown is similar

    You can’t write it like this,
    The first choice is require: '?ngModel',
    Then get the value of the text box ngModel.$modelValue instead of input.value,
    There is also no need for elements [0], element represents
    jquery The thinking is too serious. . .
