獲取Key
在代碼中,遇到需要單獨提取對象的key值時
可使用 Object.keys(object) object是你需要操作的對象
Object.keys()會返回一個存儲對象中所有key值的數組
獲取當前對象每個key對應的值使用 object[key]

JS中key-value存取
我們來使用實際的代碼測試看看結果
var mArr = ['a','b','c']; var mObj = {}; mObj['key1'] = 1; mObj['key2@'] = 2; //遍歷mObj for(var pro in mObj){ if(mObj.hasOwnProperty(pro)){ console.log('key is ' + pro +' and value is' + mObj[pro]); } } console.log(Object.keys(mArr));//結果：(3) ["0", "1", "2"] console.log(Object.keys(mObj));//結果：(2) ["key1", "key2@"] console.log(mArr[1]);//結果：b console.log(mObj['key2@']);//結果：2.

var peopleArray=[]
var peopleobj={jiangyx: "姜艷霞", yeluosen: "葉落森"}
for(let i in peopleobj){
debugger
var obj={
nickname:i,
realName:peopleobj[i]
}
peopleArray.push(obj)
}
console.log(peopleArray)
