Question

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

例如，用户有两种工作经验，表单的HTML将是：

<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>

因此有两个元素具有current和end_work类。现在，我想要这样，当用户检查is_current时，end_work将被禁用。所以，我添加了这些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：如果我检查了第一个is_current，那么第一个end_work字段将被禁用而不会影响第二个end_work。

然而，当我检查第一个is_current时，它会影响第二个end_work。我不能为每个表单更改类别，因为表单是使用cocoon gem（嵌套表单）生成的。解决方案是什么？

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>

<div class="form-group date optional resume_experiences_end_work"><label class="date optional control-label" for="resume_experiences_attributes_1_end_work_2i">End work</label><div class="form-inline"><input type="hidden" id="resume_experiences_attributes_1_end_work_3i" name="resume[experiences_attributes][1][end_work(3i)]" value="1">

使用.next(SELECTOR)仅选择具有相应next

的checkbox元素

试试这个：

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

修改

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

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script> <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> <div class="form-group date optional resume_experiences_end_work"> <label class="date optional control-label" for="resume_experiences_attributes_1_end_work_2i">End work</label> <div class="form-inline"> <input type="hidden" id="resume_experiences_attributes_1_end_work_3i" name="resume[experiences_attributes][1][end_work(3i)]" value="1"> <select id="resume_experiences_attributes_1_end_work_2i" name="resume[experiences_attributes][1][end_work(2i)]" class="date optional end_work form-control"> <option value="1">January</option> <option value="2">February</option> <option value="3" selected="selected">March</option> <option value="4">April</option> <option value="5">May</option> <option value="6">June</option> <option value="7">July</option> <option value="8">August</option> <option value="9">September</option> <option value="10">October</option> <option value="11">November</option> <option value="12">December</option> </select> <select id="resume_experiences_attributes_1_end_work_1i" name="resume[experiences_attributes][1][end_work(1i)]" class="date optional end_work form-control"> <option value="1996">1996</option> <option value="1997">1997</option> <option value="1998">1998</option> <option value="1999">1999</option> <option value="2000">2000</option> <option value="2001">2001</option> <option value="2002">2002</option> <option value="2003">2003</option> <option value="2004">2004</option> <option value="2005">2005</option> <option value="2006">2006</option> <option value="2007">2007</option> <option value="2008">2008</option> <option value="2009">2009</option> <option value="2010">2010</option> <option value="2011">2011</option> <option value="2012">2012</option> <option value="2013">2013</option> <option value="2014">2014</option> <option value="2015">2015</option> <option value="2016" selected="selected">2016</option> </select> </div> </div>

在点击事件后尝试jquery中的next函数。

＆＃13;

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

＆＃13;

如果选中则禁用表单（多表单）
