Angular-ui + D3:如何实现上下文菜单(popover vs modal)? [英] Angular-ui + D3: how to implement contextual menu (popover vs modal)?

问题描述

鉴于以下用例:

我使用 D3js 来渲染由 AngularJS 管理的对象.我想为 D3 图表添加交互性.单击 svg 元素时，我想要一种允许修改对象属性的弹出菜单.AngularJS 需要这些属性，但 D3 不呈现这些属性.

I use D3js to render objects which are managed by AngularJS. I would like to add interactivity to the D3 chart. When clicking on a svg element I would like to have a kind of popup menu allowing to modify the object properties. These properties are required by AngularJS but are not rendered by D3.

D3-Angular 集成源自 http://bl.ocks.org/biovisualize/5372077 使用闭包.

The D3-Angular integration is derived from http://bl.ocks.org/biovisualize/5372077 which uses a closure.

当前实施:

截至今天，我正在使用 angular-ui bootstrap 中的 $modal 服务来创建弹出菜单.从功能的角度来看，它工作得很好:单击 svg 元素时，D3 会调度一个事件该事件由调用 $modal 服务的 Angular 捕获在模态窗口中，我修改了对象属性

As of today I am using the $modal service from angular-ui bootstrap to create the popup menu. From a functionnality point of view it works pretty well: When clicking on a svg element, D3 dispatches an event That event is catched by Angular which calls the $modal service Within the modal window I modify the object properties

但是我对渲染不满意.我希望弹出菜单看起来像一个弹出框.它应该靠近被点击的 svg 元素.

However I am not satisfied with the rendering. I would like the popup menu to look like a popover. It should be placed close to the svg element which was clicked.

据我所知，我有两种选择:

1. 继续使用 $modal 服务并修改其外观.应该采取什么方法?使用 windowClass 选项?
2. 停止使用 $modal 服务并开始攻击 popover 指令.问题是我不认为这是可能的将这样的指令添加到 svg 元素.解决办法是在 $modal 服务附近创建一个 popover 服务.

应该选择哪个选项?以及如何实施?

Which option should be chosen? and how to implement it?

推荐答案

可以向 d3 生成的代码添加指令，唯一需要确保的是调用 $compile 内容呈现后的服务.

It is possible to add a directives to code generated by d3, only thing you need to ensure is that you call the $compile service on the content after it has been rendered.

对于给定的示例，它看起来像这样:

For the given example, it would look something like this:

    .directive('barChart', function($compile){  // inject $compile
        var chart = d3.custom.barChart();
        return {
            restrict: 'E',
            replace: true,
            template: '<div class="chart"></div>',
            scope:{
                height: '=height',
                data: '=data',
                hovered: '&hovered'
            },
            link: function(scope, element, attrs) {
                var chartEl = d3.select(element[0]);
                chart.on('customHover', function(d, i){
                    scope.hovered({args:d});
                });

                scope.$watch('data', function (newVal, oldVal) {
                    chartEl.datum(newVal).call(chart);
                    $compile(element.contents())(scope);   // <-- call to $compile
                });

                scope.$watch('height', function(d, i){
                    chartEl.call(chart.height(scope.height));
                    $compile(element.contents())(scope); // <-- call to $compile
                })
            }
        }

并且在d3的绘图函数中:

       bars.enter().append('rect')
            .classed('bar', true)
            .attr('myPopover', 'Text to show') // <-- Adding an attribute here.
            .attr({x: chartW,
                width: barW,
                y: function(d, i) { return y1(d); },
                height: function(d, i) { return chartH - y1(d); }
            })
            .on('mouseover', dispatch.customHover);
