Question

用户点击输入字段后..我想获取输入字段的ID＆amp;过滤对象＆amp;绑定Popover窗口上的数据。但Scope没有从指令更新。以下是代码，请让我知道我在哪里做错了

  var app = angular.module('MyModule', []);
    app.controller("TestController", function ($scope, $window) {
        //$scope.ID = '0';
        $scope.myObj = [{ "ID": 0, "Name": 'user0' }, { "ID": 1, "Name": 'user1' }, { "ID": 2, "Name": 'user2' }]

        $scope.GetData = function () {

            var match = $.grep($scope.myObj, function (e) {
                return e.ID == $scope.myID
            });

            return match;
        };

    });

    app.directive('popOver', function ($compile, $timeout) {
        return {
            restrict: 'A', 
            link: function (scope, el, attrs) {
                $(el).bind('click', function () {
                    scope.$apply(function () {
                        scope.myID = attrs.popoverid ;
                    });
                });


                $(el).popover({
                    placement: 'bottom',
                    container: 'body',
                    trigger: "click",
                    content: $compile($('#popover-content').html())(scope)
                });
            }
        };
    });


 <div ng-repeat="i in [0,1,2]">
         <input  style="background: transparent"
            type="text"
            pop-over
            popoverid="{{i}}" 
             id="{{i}}"
            class="form-control enterTime" data-html="true">
        <br /><br />
    </div>


    <div class="bottom hide" id="popover-content">
        <div class="arrow" style="left: 47%;"></div>
        <div class="Bground-Project"> 
            <table>
                <tr>
                    <td>
                        {{GetData()}}
                    </td>
                </tr>
            </table> 
            <button type="button" ng-click="buttonClicked()">click me</button> 
        </div>
    </div>

当写入基本类型（即字符串，数字或布尔类型）时 - 例如，scope.name = newName - “write”始终转到本地范围/对象。换句话说，子作用域获取自己的名称属性，该属性隐藏同名的父属性。修复是在父作用域中使用对象而不是基本类型。然后，子范围将获得对该对象的引用。对对象属性的任何写入（无论是来自父对象还是子对象）都将转到该对象。（子范围没有自己的对象。）
