javascript - 如果选中则禁用表单(多表单)

Question

我有经验，用户可以在那里输入他们的工作经验。因此，该表单是多种表单，用户可以添加尽可能多的体验。

例如，用户有两种工作经历，表单的 HTML 将为:

<div class="row">
  <%= f.input :start_work, as: :date, start_year: Date.today.year - 20, end_year: Date.today.year, ignore_day: true, order: [:month, :year] %><br>
  <%= f.input :is_current, input_html: {class: 'current'} %><br>
  <%= f.input :end_work, input_html: {class: 'end_work'} , as: :date, start_year: Date.today.year - 20, end_year: Date.today.year, ignore_day: true, order: [:month, :year] %>
</div>

<div class="row">
  <%= f.input :start_work, as: :date, start_year: Date.today.year - 20, end_year: Date.today.year, ignore_day: true, order: [:month, :year] %><br>
  <%= f.input :is_current, input_html: {class: 'current'} %><br>
  <%= f.input :end_work, input_html: {class: 'end_work'} , as: :date, start_year: Date.today.year - 20, end_year: Date.today.year, ignore_day: true, order: [:month, :year] %>
</div>

因此有两个元素的类为 current 和 end_work。现在，我希望当用户检查 is_current 时， end_work 将被禁用。所以，我添加这些 JS 代码:

$(document).ready(function() {
    $(".current").each(function() {
      $(this).click(function() {
        var isCurrent = $(this).prop("checked");
        if (isCurrent == true) {
          $(".end_work").prop("disabled", "disabled");
        }
        else {
          $(".end_work").prop("disabled", false);
        }
      });
    });
  });

它应该像这样工作:如果我检查第一个 is_current，那么第一个 end_work 字段将被禁用，而不影响第二个 end_work。

但是，当我检查第一个 is_current 时，它会影响第二个 end_work。我无法将每个表单的类更改为不同的，因为表单是使用 cocoon gem(嵌套表单)生成的。解决办法是什么？

这是我的 HTML 代码:

<div class="form-group boolean optional resume_experiences_is_current">
  <div class="checkbox">
    <input value="0" type="hidden" name="resume[experiences_attributes][1][is_current]">
    <label class="boolean optional" for="resume_experiences_attributes_1_is_current">
      <input class="boolean optional current" type="checkbox" value="1" checked="checked" name="resume[experiences_attributes][1][is_current]" id="resume_experiences_attributes_1_is_current">Is current
    </label>
  </div>
</div>

使用.next(SELECTOR)仅选择带有相应复选框的next元素

试试这个:

$('.current').on('change', function() {
  $(this).next('.end_work').prop('disabled', this.checked);
})

编辑:

$('.current').on('change', function() {
  $(this).closest('.form-group').next('.form-group').find('.end_work').prop('disabled', this.checked);
}).change();
