[GitBox]

zhl1232 opened a new issue, #17632:
URL: https://github.com/apache/echarts/issues/17632

   ### Version
   
   e.g.5.3.2
   
   ### Link to Minimal Reproduction
   
   _No response_
   
   ### Steps to Reproduce
   
   1. 使用 TypeScript
   2. 调用 instance.getOption() 返回类型提示是 ECBasicOption，但实际返回类似于 {
       title: [{...}],
       legend: [{...}],
       grid: [{...}]
   }
   3. 所以使用 instance.getOption().legend[0] 会提示类型错误
   元素隐式具有 "any" 类型，因为类型为 "0" 的表达式不能用于索引类型 "{}"。
     类型“{}”上不存在属性“0”。
   
   ### Current Behavior
   
    instance.getOption() 返回类型错误
   
   ### Expected Behavior
   
    instance.getOption() 返回类型和实际一至
   
   ### Environment
   
   ```markdown
   - OS:
   - Browser:
   - Framework:
   ```
