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': []
    }),
  ],
}
//初始化json数据 // [!code ++:4]

const loadDataToEditor = () => { // [!code ++:9]
  //获取编辑器实例
  let editor:DDeiEditor = proxy.$refs["ddei_editor_1"].editor;
  //获取文件json
  let fileJSON = JSON.parse(jsontext.value)
  //加载json到编辑器
  editor.loadData(fileJSON)
};
