Question

美好的一天。我正在尝试为Grafana开发一个简单的插件。我已经设法导入了外部库，现在我已经用＃34;使用它＆＃34;。

这是我在domap_ctrl.js中导入插件的方式：

System.register(['app/plugins/sdk', 'lodash','./datamaps'], function (_export, _context) {
  var PanelCtrl, _, _createClass, panelDefaults, DoMapCtrl, Datamap;

然后我想解雇数据图：

_createClass(DoMapCtrl, [
            {
              key: 'updateDoMap',
              value: function updateDoMap() {
                console.log("update: ",this.panel.foo);
                if(document.getElementById('container')){
                    new Datamap({
                      element: document.getElementById("basic")
                    });
                }
                this.nextTickPromise = this.$timeout(this.updateDoMap.bind(this), 1000);
              }
            },
            {
          key: 'onRender',
          value: function onRender() {
            console.log("onRender",)
          }
        }
        ]);

但是在将面板添加到仪表板后我得到了这个错误：

TypeError: Datamap is not a constructor

我该如何解决？提前感谢您的帮助。

即使不建议直接在dist文件夹中编辑Grafana插件（或者没有从Typescript中转换）...

要导入您的库，您还需要修改setters函数，该函数提供依赖项注入：

return {
    setters: [
    function (_lodash) {
        // example for Lodash library
        _ = _lodash.default;
    }, function (_moment) {
        // example for Moment.js library
        moment = _moment.default;
    }, function (datamap) {
        // your library
        Datamap = datamap;
    }],
    ...

Grafana，使用外部库开发插件
