{[xxx]:'xxx'}

你是想要這樣把：

let editColumn = "字符串";
結(jié)果為
{字符串: XXX, id: XXX}

可以

let para[editColumn] = editValue;
或者
let para = {[editColumn]: editValue, id: editRid}

字符串拼接試試

方法一:

let para = {id: editRid}
para[editColumn] = editValue

方法二（es6）：

let para = {[editColumn]: editValue, id: editRid}

para[editColumn] = 'xxx';

let para = {},  
para[editColumn] = deitValue,

var str = '我是字符串'
var obj = { [str] : 1 }
console.log(obj)

復(fù)制到chrome控制臺試試
