使用 Vue 的剑道图

Question

我正在按照说明进行操作 https://www.telerik.com/kendo-vue-ui/components/diagram/ 但我正在运行一个带有 .vue 文件的独立 Vue 应用程序。

首先，它在 kendo.dataviz 失败，saing kendo 未定义（在 visualTemplate 函数中）。

我查看了 STACKBLITZ 中的代码，看起来示例代码是匆忙拼凑起来的。有点“让我们导入所有内容，不要太担心”。 index.js 中的导入也是如此。性能很重要，我不想在我的组件中导入超出我需要的东西。

那么，要让它在 Vue 中运行，我实际上需要什么？

import Vue from 'vue'
import '@progress/kendo-ui'
import '@progress/kendo-theme-default/dist/all.css'
import { DataSourceInstaller, DiagramInstaller } from '@progress/kendo-diagram-vue-wrapper'

Vue.use(DiagramInstaller);
Vue.use(DataSourceInstaller);

new Vue({
    el: '#vueapp',
    data: function() {
        return {
            diagramModel: {
                children: 'items'
            },
            diagramData: myData
        }
    },
    methods: {
        kendowidgetready: function (widget) {
            widget.bringIntoView(widget.shapes)
        },
        visualTemplate: function (options) {
            var dataviz = kendo.dataviz
            var g = new dataviz.diagram.Group()
            var dataItem = options.dataItem

            g.append(new dataviz.diagram.Rectangle({
                width: 210,
                height: 75,
                stroke: {
                    width: 0
                },
                fill: {
                    gradient: {
                    type: 'linear',
                    stops: [{
                        color: dataItem.colorScheme,
                        offset: 0,
                        opacity: 0.5
                    }, {
                        color: dataItem.colorScheme,
                        offset: 1,
                        opacity: 1
                    }]
                    }
                }
            }))

            g.append(new dataviz.diagram.TextBlock({
                text: dataItem.firstName + ' ' + dataItem.lastName,
                x: 85,
                y: 20,
                fill: '#fff'
            }))

            g.append(new dataviz.diagram.TextBlock({
                text: dataItem.title,
                x: 85,
                y: 40,
                fill: '#fff'
            }))

            g.append(new dataviz.diagram.Image({
                source: 'https://demos.telerik.com/kendo-ui/content/dataviz/diagram/people/' + dataItem.image,
                x: 3,
                y: 3,
                width: 68,
                height: 68
            }))

            return g
        }
    }
})

Answer 1

我创建了一个工作示例here。我发现的唯一问题是，DataSourceInstaller 不存在于@progress/kendo-diagram-vue-wrapper 中。我必须从@progress/kendo-datasource-vue-wrapper 导入它。

作为diagramData，我从link你的postet中获取了数据。

作为index.html，我也从您的链接中获取了一个，但做了一些清理工作。

完整示例

index.js

import Vue from 'vue';
import '@progress/kendo-ui';
import '@progress/kendo-theme-default/dist/all.css';
import { DataSourceInstaller } from '@progress/kendo-datasource-vue-wrapper';
import { DiagramInstaller } from '@progress/kendo-diagram-vue-wrapper';

import diagramData from './data';

Vue.use(DiagramInstaller);
Vue.use(DataSourceInstaller);

new Vue({
  el: '#vueapp',
  data() {
    return {
      diagramModel: {
        children: 'items',
      },
      diagramData,
    }
  },
  methods: {
    kendowidgetready(widget) {
      widget.bringIntoView(widget.shapes);
    },
    visualTemplate(options) {
      var dataviz = kendo.dataviz;
      var g = new dataviz.diagram.Group();
      var dataItem = options.dataItem;

      g.append(new dataviz.diagram.Rectangle({
        width: 210,
        height: 75,
        stroke: {
          width: 0,
        },
        fill: {
          gradient: {
            type: 'linear',
            stops: [{
              color: dataItem.colorScheme,
              offset: 0,
              opacity: 0.5,
            }, {
              color: dataItem.colorScheme,
              offset: 1,
              opacity: 1,
            }],
          },
        },
      }));

      g.append(new dataviz.diagram.TextBlock({
        text: dataItem.firstName + ' ' + dataItem.lastName,
        x: 85,
        y: 20,
        fill: '#fff',
      }));

      g.append(new dataviz.diagram.TextBlock({
        text: dataItem.title,
        x: 85,
        y: 40,
        fill: '#fff',
      }));

      g.append(new dataviz.diagram.Image({
        source: 'https://demos.telerik.com/kendo-ui/content/dataviz/diagram/people/' + dataItem.image,
        x: 3,
        y: 3,
        width: 68,
        height: 68,
      }));

      return g;
    },
  },
});
