Because later in actual use, I found that sometimes, The background will only return the ID value of one region, so optimization has been done here. You can only pass in the ID value, for example:

...
area: [
 {ID: &#39;01&#39;},
 {ID: &#39;0401&#39;},
 {ID: &#39;060105&#39;}
],
...

This value is all the areas currently selected by the component. The returned value It is an array composed of multiple objects containing regional data. The data structure is the same as the area parameter

Simple example
