用键（JS）排序对象

Question

有对象。像这样

需要对它进行排序，在结果：MO，星期二，星期三，星期四，星期五，日，苏

尝试这样做，但没有工作

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

复杂。更容易：

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

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