Ответ 1
Очень просто сделать приложение angular и использовать d3 в вашем приложении. Прежде всего вам нужно узнать что-то о структуре angular. Как вы знаете, вам нужно ng-app использовать библиотеку angular, вы можете определить ее в теге html или body. Если вы хотите делиться данными между вашими директивами или работать с angular services, вам нужен контроллер angular. В этом случае $scope делится между контроллером и директивами. Последняя функция, которую вы должны использовать, является директивой.
Таким образом, согласно этому отрывку, нормализуйте свой код. Прежде всего, вы не должны определять директиву для параметра css. Просто добавьте все из них в файл и введите его на главную страницу или вставьте в тег <style>.
Поскольку я упоминаю директиву, просто используйте функции JavaScript.
Итак, пусть реализует angular приложение:
var app = angular.module('App');
var ctrl = app.controller("treeCrtl", ["$scope", function ($scope) {
}]);
Это две функции: контроллер ng-app и angular, и это директива.
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) {

Есть несколько моментов, которые я должен упомянуть:
1- Если вам нужно реализовать разные директивы, просто используйте тот же формат с разными именами.
2- Чтобы связать свой код с тегом директивы, вы должны использовать этот тип кодирования:
d3.select(el[0]), Внимание el - параметр функции связи.
3- Если вы используете другой каталог для flare.json, замените эту часть:
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"
});
При этом:
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"
});
});
