我正在开发一个 Angular 应用程序。我想在下面添加d3 chart ，但是当我简单地将 Javascript 插入到我的 Controller 中时，样式到我的样式表中，什么都没有出现。有些东西向我暗示 Angular 和 D3 表现不佳。
我已经附加了我的 Angular 设置而没有添加 d3 对象。我想将它添加到 workHistory Controller/Directive/View 中。关于设置它的正确方法的任何建议是什么？谢谢!

//insert d3 view here

//insert d3 styles here
最佳答案
制作 angular 非常简单应用和使用d3在您的应用程序中。首先你需要了解angular结构体。如您所知，您需要ng-app要使用 Angular 库，您可以在 html 中定义它或 body标签。如果您想在指令之间共享数据或使用 Angular services你需要 Angular Controller 。在这种情况下 $scope在 Controller 和指令之间共享。您必须使用的最后一个函数是指令。
因此，根据这篇文章，让我们规范化您的代码。首先你不应该为 css 定义一个指令。参数，只需将它们全部添加到一个文件中并将其注入(inject)到主页中或将它们插入到 <style>标签。
正如我提到的指令仅由 JavaScript 使用职能。
所以让我们实现 Angular 应用程序:
var app = angular.module('App');
var ctrl = app.controller("treeCrtl", ["$scope", function ($scope) {
}]);
这是两个函数，
ng-app和 Angular Controller ，这是指令。ctrl.directive("workHistory", function () {
return {
restrict: 'E',
link: function link(scope, el, attr) {
var div = d3.select("body")
.append("div") // declare the tooltip div
.attr("class", "tooltip")
.style("opacity", 0);
var margin = { top: 20, right: 120, bottom: 20, left: 120 },
width = 960 - margin.right - margin.left,
height = 800 - margin.top - margin.bottom;
var i = 0,duration = 750,root,select2_data;
var diameter = 960;
var tree = d3.layout.tree()
.size([height, width]);
var diagonal = d3.svg.diagonal()
.projection(function (d) { return [d.y, d.x]; });
var svg = d3.select(el[0]).append("svg")
.attr("width", width + margin.right + margin.left)
.attr("height", height + margin.top + margin.bottom)
.append("g")
.attr("transform", "translate(" + margin.left + "," + margin.top + ")");
//recursively collapse children
function collapse(d) {
if (d.children) {
d._children = d.children;
d._children.forEach(collapse);
d.children = null;
}
}
// Toggle children on click.
function click(d) {
if (d.children) {
d._children = d.children;
d.children = null;
}
else {
d.children = d._children;
d._children = null;
}
update(d);
}
function openPaths(paths) {
for (var i = 0; i < paths.length; i++) {
if (paths[i].id !== "1") {//i.e. not root
paths[i].class = 'found';
if (paths[i]._children) { //if children are hidden: open them, otherwise: don't do anything
paths[i].children = paths[i]._children;
paths[i]._children = null;

update(paths[i]);
}

function update(source) {

function extract_select2_data(node, leaves, index) {

有几点我不得不提:
1-如果您必须实现不同的指令，只需使用具有不同名称的相同格式。
2-要将您的代码链接到指令标签，您必须使用这种类型的编码:
d3.select(el[0]) , 关注 el是链接函数参数。3- 如果您对
flare.json 使用不同的目录替换这部分:root = values;
select2_data = extract_select2_data(values, [], 0)[1];//I know, not the prettiest...
root.x0 = height / 2;
root.y0 = 0;
root.children.forEach(collapse);
update(root);
//init search box
$("#search").select2({
data: select2_data,
containerCssClass: "search"
});
有了这个:
d3.json("flare.json", function(error,values){
root = values;
select2_data = extract_select2_data(values,[],0)[1];//I know, not the prettiest...
root.x0 = height / 2;
root.y0 = 0;
root.children.forEach(collapse);
update(root);
//init search box
$("#search").select2({
data: select2_data,
containerCssClass: "search"
});
});
