How to find the closest sibling in jQuery


I am trying to learn jQuery, I have following mark up

In a div, I have two texts date and description and two buttons edit and delete.

When I click the edit button, I want to get the date and description of that div

Here I am trying to get it using parents() selector, how can I use closest() selector here , if it is not possible with the current markup please suggest how can I proceed with closest() selector.

$(document).ready(function() {
  //If i click on edit button . I want to select the corresponding date and description .How can we do that?

  $(".taskTemplate .edit").on('click', function(event) {
    editTask(event.target);
  });
});

function editTask(node) {

  var date = $(node).parents('.taskTemplate').find('.date').html();
  alert(date);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="taskTemplate">
  <span class="date">205-10-09</span>
  <span class="desc">description of task</span>
  <input type="button" class="edit" value="edit">
  <input type="button" class="delete" value="delete">
  <span class="done">done</span>
</div>

<div class="taskTemplate">
  <span class="date">2015-11-19</span>
  <span class="desc">description of task2</span>
  <input type="button" class="edit" value="edit">
  <input type="button" class="delete" value="delete">
  <span class="done">done</span>
</div>


Solution

  • Just replace parents() by closest() in :

    var date = $(node).closest('.taskTemplate').find('.date').html();
    

    Hope this helps.

    $(document).ready(function() {
      $(".taskTemplate .edit").on('click', function(event) {
          editTask(event.target);
      });
    });
    
    function editTask(node) {
      var closest_div = $(node).closest('.taskTemplate');
      
      var date = closest_div.find('.date').text();
      var description = closest_div.find('.desc').text();
    
      console.log(date, `|`, description);
    }
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
    <div class="taskTemplate">
      <span class="date">205-10-09</span>
      <span class="desc">description of task</span>
      <input type="button" class="edit" value="edit">
      <input type="button" class="delete" value="delete">
      <span class="done">done</span>
    </div>
    
    <div class="taskTemplate">
      <span class="date">2015-11-19</span>
      <span class="desc">description of task2</span>
      <input type="button" class="edit" value="edit">
      <input type="button" class="delete" value="delete">
      <span class="done">done</span>
    </div>
