Angular使用jQuery插件与外部控制器中的对象

Question

I'm new to Angular and I wanted to use a jQuery Plugin (d3pie.js). I googled my need and I found few examples that explain that I have to create a directive and put in my parameters (and to be sincere it's a little bit confusing for a beginner like me).

My problem is that I didn't find how to use a plugin that requires an object as argument, knowing that this object is in an other controller ?

Here is an example using bars, a controller that hods your data and a directive with D3. This was all found using this link but I modified it slightly for better angular code style. http://odiseo.net/angularjs/proper-use-of-d3-js-with-angular-directives .

1. All your D3 logic and presentation must be contained within a directive
2. Use HTML-declarative syntax to feed of data to your directive instances
3. By doing that, you can store the data in your controller, passing it to your D3 directive via two-way data binding of parameters

 angular.module('myApp', []) .controller('BarsController', function($scope) { $scope.myData = [10,20,30,40,60, 80, 20, 50]; }) //camel cased directive name //in your HTML, this will be named as bars-chart .directive('barsChart', function ($parse) { //explicitly creating a directive definition variable //this may look verbose but is good for clarification purposes //in real life you'd want to simply return the object {...} var directiveDefinitionObject = { //We restrict its use to an element //as usually <bars-chart> is semantically //more understandable restrict: 'E', //this is important, //we don't want to overwrite our directive declaration //in the HTML mark-up replace: false, //our data source would be an array //passed thru chart-data attribute scope: {data: '=chartData'}, link: function (scope, element, attrs) { //in D3, any selection[0] contains the group //selection[0][0] is the DOM node //but we won't need that this time var chart = d3.select(element[0]); //to our original directive markup bars-chart //we add a div with out chart stling and bind each //data entry to the chart chart.append("div").attr("class", "chart") .selectAll('div') .data(scope.data).enter().append("div") .transition().ease("elastic") .style("width", function(d) { return d + "%"; }) .text(function(d) { return d + "%"; }); //a little of magic: setting it's width based //on the data value (d) //and text all with a smooth transition } }; return directiveDefinitionObject; }); 

 .chart { background: #eee; padding: 3px; } .chart div { width: 0; transition: all 1s ease-out; -moz-transition: all 1s ease-out; -webkit-transition: all 1s ease-out; } .chart div { font: 10px sans-serif; background-color: steelblue; text-align: right; padding: 3px; margin: 5px; color: white; box-shadow: 2px 2px 2px #666; }
