如何将angularjs指令绑定到一个链接函数定义的d3js节点 [英] How to bind an angularjs directive to a d3js node defined in a link function

问题描述

我想在一个AngularJs应用程序使用d3js图形，然后绑定指令到节点。

I would like to use a d3js graph in an AngularJs app, and then bind directives to the nodes.

首先，我把JS code在指令的纽带作用，一切运行良好。

First I put the js code in the link function of a directive and everything works well.

angular.module('myApp', []).

directive('grapheForces', function() {
    return {
        restrict: 'A',
        link: function (scope, element) {
            var width = 450;
            var height = 400;
            var color = d3.scale.category20();

            scope.$watch('grapheDatas', function (grapheDatas) {
                var force = d3.layout.force()
                .charge(-120)
                .linkDistance(30)
                .size([width, height])
                .nodes(grapheDatas.nodes)
                .links(grapheDatas.links)
                .start();

                var svg = d3.select("body").append("svg")
                .attr("width", width)
                .attr("height", height);

                var link = svg.selectAll(".link")
                .data(grapheDatas.links)
                .enter().append("line")
                .attr("class", "link")
                .style("stroke-width", function(d) { return Math.sqrt(d.value); });

                var node = svg.selectAll(".node")
                .data(grapheDatas.nodes)
                .enter().append("circle")
                .attr("class", "node")
                .attr("r", 5)
                .style("fill", function(d) { return color(d.group); })
                .call(force.drag);

                node.append("title")
                .text(function(d) { return d.name; });

                force.on("tick", function() {
                    link.attr("x1", function(d) { return d.source.x; })
                    .attr("y1", function(d) { return d.source.y; })
                    .attr("x2", function(d) { return d.target.x; })
                    .attr("y2", function(d) { return d.target.y; });

                    node.attr("cx", function(d) { return d.x; })
                    .attr("cy", function(d) { return d.y; });
                });
            });
        }
    }
}).

然后我想一个提示添加到节点上，所以我去：

And then I would like to add a tooltip to the nodes, so I go :

                var node = svg.selectAll(".node")
                .attr("tooltip", function(){
                    return "tooltipTextHere";
                 });

由于我用角引导，提示是一种指令。
工具提示属性是HTML结果以及present：

As I use angular-bootstrap, tooltip is a directive. The tooltip attribute is well present in the html result :

<circle tooltip="tooltipTextHere" class="nodeCircle" r="4.5" style="fill: #b0c4de;"></circle>

但提示是无效的，因此它也适用于每一个绑定我这样的指令。

But the tooltip is ineffective, and so it goes for every directive I bind like that.

我想这是因为该指令尚未在编译阶段采取的帐户，但我无法找到如何做到这一点，因为我到达AngularJs我目前的COM prehension限制。

I guess it is because the directive has not been taken in account during the compile phase, but I can't find how to do that as I reach my current comprehension limits in AngularJs.

你有我怎么能做到这一点的想法？
非常感谢你为你的非常有价值的答案。

Do you have an idea of how i could make it happen ?? Thank you very much for your very valuable answers.

我已经回答了一个非常类似的<一个href=\"http://stackoverflow.com/questions/20399336/how-do-i-use-angularjs-directives-in-generated-d3-html/\">question这里。你可以看到完整的答案在那里。

I have answered a very similar question here. You can see the full answer there.

基本上，你添加提示属性后，您需要删除的东西您的自定义指令属性如 element.removeAttr（graphe部队）然后运行 $编译（元）（范围）这样的应用程序会发现提示指令。

Basically, after you add the tooltip attributes, you need to remove your custom directive attribute with something like element.removeAttr("graphe-forces") and then run $compile(element)(scope) so the app will find the tooltip directive.

下面是一个工作示例的小提琴。
