Question

以下解决方案将在使用lambda函数时运行良好。对于某些业力测试用例失败，我必须避免在排序中使用lambda函数。我不知道如何克服这个问题。现在以下代码不是为我工作

var test=[{ID: "91",Name: "sgtue", standardID: "1"},
{ID: "41",Name: "asdfasdf", standardID: "2"},
{ID: "5", Name: "credd", standardID: "2"},
{ID: "2",Name: "dddawer", standardID: "2"},
{ID: "2",Name: "dsfadf", standardID: "3"},
{ID: "275", Name: "xcvcvc", standardID: "201"}
];


var groupOrder = [1,3,2,201];
var testSorted = test.sort(function (a, b) {groupOrder.indexOf(parseInt(a.standardID))-groupOrder.indexOf(parseInt(b.standardID))}); 


console.log(testSorted);

您需要返回排序计算的结果。

var test = [{ ID: "91", Name: "sgtue", standardID: "1" }, { ID: "41", Name: "asdfasdf", standardID: "2" }, { ID: "5", Name: "credd", standardID: "2" }, { ID: "2", Name: "dddawer", standardID: "2" }, { ID: "2", Name: "dsfadf", standardID: "3" }, { ID: "275", Name: "xcvcvc", standardID: "201" }],
    groupOrder = [1, 3, 2, 201];

test.sort(function(a, b) {
    return groupOrder.indexOf(+a.standardID) - groupOrder.indexOf(+b.standardID);
    // ^^^
});

console.log(test);

使用javascript使用lambda函数的排序函数
