带指令的角度重复 [英] angular ng-repeat with directive

问题描述

我是新的角和有以下问题，我需要帮助。
我正在使用角度图指令 http://jtblin.github.io/angular -chart.js / 构建图表板。我得到了以下的情况：

i'm new to angular and have the following issue where i need assistence. I'm using angular charts directives http://jtblin.github.io/angular-chart.js/ to build a chart board. I got the follwoing scenario:

我有一个指令一个视图和一个用户代码在这里关联控制器。
在控制器内应该有一个数组图表[]，它保存对象。
这些对象应该与chart伪指令双向绑定。
什么是适当的方式这样做？我将动态绘制我的图表，没有任何控制器连接到每个图表。可能吗？

I have a directive a view and anenter code here associated controller. Inside the controller there should be an array charts[] which holds objects. these objects should be two-way binded with the chart directive. What is the appropriate way to do so? I will bild my charts dynamically without any controller attached to each chart. Is that possible?

<div ng-repeat="c in charts">
<chart></chart>
<div>

reportViewController.js

reportViewController.js

angular.module('app').controller('reportViewController', reportViewCtrl);

reportViewCtrl.$inject = ['$scope', '$log', 'RefinerService', 'appConfig'];


function reportViewCtrl($scope, $log, RefinerService, appConfig) {
    $scope.charts = [];
    var chart = {
                ID: 1
                , Visible: true
                , Type: "chart-line"
                , Data: [
                    [65, 59, 80, 81, 56, 55, 40]
                    , [28, 48, 40, 19, 86, 27, 90]
                ]
                    , Labels: ['2006', '2007', '2008', '2009', '2010', '2011', '2012']
                    , Series: ['Product A', 'Product B']

    }
    $scope.charts.push(chart);
}

chartTemplate.html

<div class="chart-container" flex>
<canvas class="chart {{c.Type}}" 
  data="{{c.Data}}" 
  labels="{{c.Labels}}" 
  series="{{c.Series}}">
</canvas>
</div>

directive.js

directive.js

angular.module('app').directive('chart', function () {
    return {
        restrict: 'E',
        templateUrl: 'templates/chartTemplate.html',
        scope: {
            id: '@id',
            type: '@type'
        }
    };
});

您需要将ng-repeat中的c传递到图表指令。

You need to pass the "c" from the ng-repeat into the chart directive.

这里是一个小提琴演示： http://jsfiddle.net/8zwmt18L/1/

Here is a fiddle to demonstrate: http://jsfiddle.net/8zwmt18L/1/

< div ng-repeat =c in charts>
< chart chart-data =c>< / chart>
< div>

在您的指示中：

code> angular.module（'app'）。directive（'chart'，function（）{
return {
restrict：'E'，
templateUrl：'templates / chartTemplate .html'，
scope：{
chartData：'='
}
};
}）;

angular.module('app').directive('chart', function () { return { restrict: 'E', templateUrl: 'templates/chartTemplate.html', scope: { chartData: '=' } }; });

在您的指令模板中：

< div class =chart-containerflex&
< canvas class =chart chart-base
chart-type =chartData.Type
data =chartData.Data
labels =chartData.Labels
series =chartData.Series>
< / canvas>
< / div>

在图表的数据中，您的类型需要为Line ，而不是chart-line或chart-bar

In the data for the charts, your types will need to be "Line" or "Bar", and not "chart-line" or "chart-bar"
