用鍵（JS）排序對象

Question

有對象。像這樣

需要對它進行排序，在結果：MO，星期二，星期三，星期四，星期五，日，蘇

嘗試這樣做，但沒有工作

const sortOrder = {'mo': 1, 'tu': 2, 'we': 3, 'th':4,'fr':5, 'sa':6, 'su':7} 
     const res = result.map(o => Object.assign({}, ...Object.keys(o).sort((a, b) => sortOrder[a] - sortOrder[b]).map(x => { return { [x]: o[x]}}))) 

Answer 1

複雜。更容易：

var days = ["mo","tu","we","th","fr","sa","su"]; 

result.sort((a,b)=> days.indexOf(a.day) - days.indexOf(b.day));
