Question

我有这样的代码，需要为现有代码使用for循环，而不是显示1,2,3等代码在我尝试使用不同类型但获取任何数据的javascript文件中

$rootScope.AgeM = [
    {M: '1'},
    {M: '2'},
    {M: '3'},
    {M: '4'},
    {M: '5'},
    {M: '6'},
    {M: '7'},
    {M: '8'},
    {M: '9'},
    {M: '10'},
    {M: '11'},
    {M: '12'},
]

for在数组中。重复相同的数据或输入1到12之间的数字感到有点困难

您需要使用Object.keys

  function getAge() {
    let AgeM = [
        {M: '1'},
        {M: '2'},
        {M: '3'},
        {M: '4'},
        {M: '5'},
        {M: '6'},
        {M: '7'},
        {M: '8'},
        {M: '9'},
        {M: '10'},
        {M: '11'},
        {M: '12'},
    ]
    let age;
    let index = 0;

    Object.keys(AgeM).forEach(function (key) {

        age = AgeM[key];
        console.log('for index ', index + ' age is :' + age.M);
        index++;
    });
}

我有这样的代码需要为现有代码使用循环
