js realizes the sharing of three-level linkage plug-ins in provinces and municipalities

This article mainly shares with you the js implementation of the three-level linkage plug-in of provinces and municipalities. I hope this article can help everyone better understand the implementation method of the three-level linkage plug-in of provinces and municipalities.

// 页面上先引入css与js文件
<p id="wrap"></p>

There are no restrictions on the container tags in the page, just give an ID

var address = new Address({
    wrapId: 'wrap',
    showArr: ['provinces','citys','areas'],
    beforeCreat:function(){
        console.log("beforeCreat")
    },
    afterCreat:function(){
        console.log('afterCreat');
    }
})

• ##wrapId: "wrap" // The wrap here is the above Container id

• showArr: ['provinces','citys','areas'] // This represents the id of the province, city, and district container respectively.

  For example: If the passed array

  ['provinces','citys','areas'] has a length of 3, then there will be Provinces and cities, the three strings in the array are the ids of the province, city, and district containers respectively

  

  For example, the passed array

  ['provinces', 'citys']The length is 2, then the province and city will appear. The two strings in the array are the ids of the province and city containers

  

  If the array length is 1, we won’t say it.

• ##beforeCreat

  Callback executed before the plug-in starts to create Function

• afterCreat

  Callback function executed after the plug-in is created
