加载数据

本示例演示了怎样加载已有的JSON到设计器中。

如需了解详细的API教程以及参数说明，请参考DDei文档

外部数据JSON

demo.vue

<script setup lang="ts">
import DDeiEditorView from "ddei-editor";
import { DDeiCoreStandLayout } from "ddei-editor";
import { ref,getCurrentInstance } from "vue"; // [!code ++:4]
import {DDeiEditor,DDeiFile} from "ddei-editor";
//获取主对象实例，代替this获取$refs
const {proxy} = getCurrentInstance()const options = {config: { "grid": 0, //网格线 // [!code --]"background": { color: "blue", opacity: 0.1 }, //背景色 // [!code --]"background": -1, //无背景 // [!code ++]initData: { // [!code --:8]controls: [{model: "102010",text: "初始化图形"},]}},//配置扩展插件extensions: [//布局的配置DDeiCoreStandLayout.configuration({//配置插件'top': [],'middle': ['ddei-core-panel-canvasview', 'ddei-core-panel-quickcolorview'],'bottom': [],'left': [],'right': []}),],
