我有一个对象数组

item_array = [{
                "Email Address": "c",
                "First Name": "a",
                "Last Name": "b",
                "Permission": "Training Administrator",
                "Telephone": "d",
                "User Group": "Company Administrator"
            },
            {
                "Email Address": "3",
                "First Name": "1",
                "Last Name": "2",
                "Permission": "6",
                "Telephone": "4",
                "User Group": "5"
            }];

我如何按这样的给定数组对这个数组进行排序

item_order = ["First Name", "Last Name", "Email Address", "Permission", "Telephone", "User Group"];

我需要像给定的数组一样对对象的对象数组进行排序

iteam_order

预期结果

item_array = [{
                "First Name": "a",
                "Last Name": "b",
                "Email Address": "c",
                "Permission": "Training Administrator",
                "Telephone": "d",
                "User Group": "Company Administrator"
            },
            {
                "First Name": "1",
                "Last Name": "2",
                "Email Address": "3",
                "Permission": "6",
                "Telephone": "4",
                "User Group": "5"
            }];

你

您可以使用map并reduce喜欢这样的：

const item_array = [{"Email Address":"c","First Name":"a","Last Name":"b","Permission":"Training Administrator","Telephone":"d","User Group":"Company Administrator"},{"Email Address":"3","First Name":"1","Last Name":"2","Permission":"6","Telephone":"4","User Group":"5"}],
      item_order = ["First Name","Last Name","Email Address","Permission","Telephone","User Group"];

const ordered = item_array.map(item =>
    item_order.reduce((acc, key) => ( acc[key] = item[key], acc ), {})
);

console.log(ordered)
