假设我有一个图表指令（如饼图）和一个设置指令，其中包含用于修改图表指令设置的表单。设置指令显示在模式对话框中。

如何使设置指令中的更改在图表指令中生效？

可以有多个图表指令，每个都有独立的设置。每个图表的设置实际上将在设置模式中显示为选项卡，但我将其省略以保持示例简单。

以下是我尝试/考虑过的一些事情：

“使用工厂共享设置值。” 这失败了，因为我可能有多个图表指令，每个都有单独的设置。

“让设置指令成为图表指令的子项。” 设置指令不能是图表指令的子指令，因为它需要在模式中呈现。

这是一个带有一些相关片段的plunkr：

<div ng-controller="Controller">
    <a href ng-click="showSettings()">Settings</a>
    <chart></chart>
    <chart></chart>
</div>

JS：

app.controller("Controller", function ($scope, $modal) {
    $scope.showSettings = function () {
        $modal.open({
                    scope: $scope,
                    template: "<h1>Settings Modal</h1><settings></settings>"
                }
        );
    }
});

app.directive("chart", function () {
    return {
        restrict: 'E',
        template: '<h1>Chart Directive</h1><p>someChartSetting: {{someChartSetting}}</p>',
        controller: function ChartController($scope) {
            // This value represents a setting that I need to modify via the settings modal.
            $scope.someChartSetting = "on";
        }
    }
})

app.directive("settings", function () {
    return {
        restrict: 'E',
        template: '<a href ng-click="toggleSettings()">Toggle someChartSetting</a>',
        controller: function SettingsController($scope) {
            $scope.toggleSettings = function () {
                console.log("Toggle clicked");
                // This is where I need to modify the someChartSetting value from chart.
            }
        }
    }
})
