Props

area

The area parameter is required and represents the region data when the component is initialized. , can be empty. area is an array containing multiple objects, where the data structure of each object is as follows:

...
area: [
 {Name: '北京', ID: '01'},
 {Name: '南京', ID: '0401'},
 {Name: '西湖区', ID: '060105'}
],
...

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: '01'},
 {ID: '0401'},
 {ID: '060105'}
],
...

##selected

selected is an event published internally by the component. You can subscribe to this event outside the component to get the value it returns. 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

<p>
  <addressmap :area="area" @selected="selected"></addressmap>
</p>
