- import * as ExcelIO from '@grapecity/spread-excelio'
- async mounted() {
- this.spread = new GC.Spread.Sheets.Workbook(this.$refs.spread, { sheetCount: 1 });
- const response = await fetch('/templates/default.xlsx'); // 放在 public/templates/
- const arrayBuffer = await response.arrayBuffer();
- this.spread.import(arrayBuffer, () => {
- console.log('默认模板已加载');
- }, (err) => {
- console.error('导入失败', err);
- }, {
- fileType: GC.Spread.Sheets.FileType.excel
- });}
报错Error in mounted hook (Promise/async): "TypeError: Cannot read properties of undefined (reading 'excel')"是为啥怎么解决 |
