關(guān)于element select框默認(rèn)值賦值不成功問題逗抑，注意兩點：
1、v-model里面的數(shù)據(jù)和遍歷出來value值數(shù)據(jù)類型不一樣嘀略。（例：item.provinces類型是number蜈缤，province類型是String。類型不一樣導(dǎo)致賦值不成功）
2势就、遍歷數(shù)據(jù)和賦值的先后順序，必須保證數(shù)據(jù)先遍歷后賦值脉漏。
注意注意注意：要為select設(shè)定默認(rèn)值苞冯，只要把v-model綁定的值和你想要選中option的value值設(shè)置一樣即可。

重要的事情說三遍data定義必須與后臺一致的數(shù)據(jù)類型侧巨，比如后臺返回來的是數(shù)字抱完，就必須定義數(shù)字類型的
pid:0,//必須制定Number（與后臺返回來的數(shù)據(jù)類型一致）
cid:0,//必須制定Number（與后臺返回來的數(shù)據(jù)類型一致）
aid:0,//必須制定Number（與后臺返回來的數(shù)據(jù)類型一致）
賦值的時候也必須是數(shù)字類型的

if(id){
api.getVillageInfo(id).then(res => {
