遍历dom嵌套对象

Question

I have nested inputs in my html which I am trying to get the value of. 我在我试图获取其值的html中嵌套了输入。 I've tried many methods with no luck. 我已经尝试了很多方法，但是没有运气。 I want to get the value of all the inputs into different variables in my javascript file. 我想将所有输入的值转换成我的javascript文件中的不同变量。

            <script src="js/add-trainee-main.js" type="module"></script>
</body>

</html>

my jquery looks like this : the 'addBtn' is correct , and iv tryed many methods from here : 我的jQuery看起来像这样：'addBtn'是正确的，并且iv从这里尝试了许多方法：

https://api.jquery.com/category/traversing/ https://api.jquery.com/category/traversing/

 handleAddTrainee() {
        // console.log(this);
        let addBtn = $('.addTrainee');
        // console.log(addBtn)
        debugger
        // $('.addTrainee').on('click', () => {
        // let $traineeForm = $(this).closest('.trainee-from') // need to know the way you orginized the html.

        // cetch trainee data 

        //----
        let fullName = addBtn.closest('.add_trainee').find('.inp').find('input.fullName').val();
        let gender = $(this).closest('.gender').val();
        let age = $(this).closest('.age').val();
        let phoneNumber = $(this).closest('.phoneNumber').val();
        let adress = $(this).closest('.adress').val();
        let dateMedicalAssuranceEnd = $(this).closest('.dateMedicalAssuranceEnd').val();
        let dateMembershipStart = $(this).closest('.dateMembershipStart').val();
        let dateMembershipEnd = $(this).closest('.dateMembershipEnd').val();
        //-----
        let traineeForm = {
            fullName: fullName,
            gender: gender,
            age: age,
            phoneNumber: phoneNumber,
            adress: adress,
            dateMedicalAssuranceEnd: dateMedicalAssuranceEnd,
            dateMembershipStart: dateMembershipStart,
        }
        this.gymRepo.addTrainee(traineeForm).then(() => {
                alert("new trainee as been saved");
            })
            // })
    }

Answer 1

you are using jquery so why don't you use some thing like that 您正在使用jQuery，为什么不使用类似的东西

$(':input').each(function(){
if($(this).hasClass('addTrainee'))
    return;
console.log($(this).val() );
});

this will get you the values of all the input except for the save button 这将为您获取所有输入的值（保存按钮除外）

Answer 2

I would use @aa-Ahmed-aa answer with a more complete example. 我将使用@ aa-Ahmed-aa答案以及更完整的示例。

const recoverValues = function() {
  const values = {};

  $(':input').each(function(){
  if($(this).hasClass('addTrainee'))
    return;
  // very ugly code
  values[$(this).attr('class')] = $(this).val();
  });

  return values;
}

So that you can retrieve a good looking json for all your inputs except the submit button. 这样您就可以为除了提交按钮之外的所有输入检索一个漂亮的json。
