Question

我有一个模态用于编码训练营分配-

我列出了一周中的7天以及周末/工作日选项。

我以为我可以使用Jquery .each和CSS：check拉出我为这些输入分配的值，但是每次尝试记录正在推送的数组时，我似乎做错了到-它返回一个空数组。

这是我在StackOverflow上的第一篇文章，我对编码非常陌生，请保持柔和：）

预先为语法和格式道歉。就像我说的那样，我是超级新手，只编码了1.5个月。

我尝试为所有复选框赋予不同的ID，然后将值一个一个地拉入数组，还尝试给它们取相同的名称，以便可以使用CSS选中的功能使用.each一次将其全部拉入。似乎都不起作用

//below is the check box portion of the modal//

<div class="form-check form-check-inline">
        <input class="form-check-input" type="checkbox" name="daysOfWeek" value="Monday">
        <label for="Monday">Monday</label>
      </div>
      <div class="form-check form-check-inline">
        <input class="form-check-input" type="checkbox" name="daysOfWeek" value="Tuesday">
        <label for="Tuesday">Tuesday</label>
      </div>
      <div class="form-check form-check-inline">
            <input class="form-check-input" type="checkbox" name="daysOfWeek" value="Wednesday">
            <label for="Wednesday">Wednesday</label>
    </div>
    <div class="form-check form-check-inline">
            <input class="form-check-input" type="checkbox" name="daysOfWeek" value="Thursday">
            <label  for="Thursday">Thursday</label>
    </div>
    <div class="form-check form-check-inline">
            <input class="form-check-input" type="checkbox" name="daysOfWeek" value="Friday">
            <label  for="Friday">Friday</label>
    </div>
    <div class="form-check form-check-inline">
            <input class="form-check-input" type="checkbox" name="daysOfWeek" value="Saturday">
            <label  for="Saturday">Saturday</label>
    </div>
    <div class="form-check form-check-inline">
            <input class="form-check-input" type="checkbox" name="daysOfWeek" value="Sunday">
            <label for="Sunday">Sunday</label>
    </div>
    <div class="form-check form-check-inline">
      <input class="form-check-input" type="checkbox" name="daysOfWeek" value="Weekday">
      <label for="Weekday">Weekday</label>
    </div>
    <div class="form-check form-check-inline">
    <input class="form-check-input" type="checkbox" name="daysOfWeek" value="Weekend">
    <label  for="Weekend">Weekend</label>
    </div>


// here is where I try to call the values of which boxes are checked back//

$("#submitButton").on("click", function () {
    event.preventDefault();
            var  daysOfWeek1 = [];
                  $.each($("input[name='dayOfWeek']:checked"), function(){
                    daysOfWeek1.push($(this).val());
                  });

      console.log(daysOfWeek1)

    });

我想找回一个数组，其中包含我为每个复选框选项输入的值（字符串集），并能够将其存储在变量中并进行控制台。

现在我只得到一个空数组

Answer 1

更简单-只需使用map，然后使用扩展语法将其转换为数组（以删除多余的属性）即可：

$("#submitButton").on("click", function() {
  event.preventDefault();
  var daysOfWeek1 = [...$("input[name='daysOfWeek']:checked").map((i, el) => $(el).val())];
  console.log(daysOfWeek1)
});

<script src="https://code.jquery.com/jquery-3.3.1.js"></script>
<div class="form-check form-check-inline">
  <input class="form-check-input" type="checkbox" name="daysOfWeek" value="Monday">
  <label for="Monday">Monday</label>
</div>
<div class="form-check form-check-inline">
  <input class="form-check-input" type="checkbox" name="daysOfWeek" value="Tuesday">
  <label for="Tuesday">Tuesday</label>
</div>
<div class="form-check form-check-inline">
  <input class="form-check-input" type="checkbox" name="daysOfWeek" value="Wednesday">
  <label for="Wednesday">Wednesday</label>
</div>
<div class="form-check form-check-inline">
  <input class="form-check-input" type="checkbox" name="daysOfWeek" value="Thursday">
  <label for="Thursday">Thursday</label>
</div>
<div class="form-check form-check-inline">
  <input class="form-check-input" type="checkbox" name="daysOfWeek" value="Friday">
  <label for="Friday">Friday</label>
</div>
<div class="form-check form-check-inline">
  <input class="form-check-input" type="checkbox" name="daysOfWeek" value="Saturday">
  <label for="Saturday">Saturday</label>
</div>
<div class="form-check form-check-inline">
  <input class="form-check-input" type="checkbox" name="daysOfWeek" value="Sunday">
  <label for="Sunday">Sunday</label>
</div>
<div class="form-check form-check-inline">
  <input class="form-check-input" type="checkbox" name="daysOfWeek" value="Weekday">
  <label for="Weekday">Weekday</label>
</div>
<div class="form-check form-check-inline">
  <input class="form-check-input" type="checkbox" name="daysOfWeek" value="Weekend">
  <label for="Weekend">Weekend</label>
  <button id="submitButton">Submit</button>
</div>

哎呀。完全有效-我只是在下面使用dayOfWeek，在上面使用daysOfWeek ...
