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>
jQuery next() Method The next() method returns the next sibling element of the selected element. Sibling elements are elements that share the same parent. The DOM tree: This method traverse forward along the next sibling of DOM elements.
jQuery closest() Method The closest() method returns the first ancestor of the selected element. An ancestor is a parent, grandparent, great-grandparent, and so on.
The siblings() is an inbuilt method in jQuery which is used to find all siblings elements of the selected element. The siblings are those having same parent element in DOM Tree.
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);
}

You can use .siblings()
to select .date
, .desc
siblings of .edit
element
$(document).ready(function() {
//If i click on edit button . I want to select the corresponding date and description .How can we do that?
$(".taskTemplate .edit").on('click', function(event) {
editTask($(this).siblings(".date, .desc"));
});
});
function editTask(nodes) {
var data = $.map(nodes, function(el) {
return `${el.className}: ${el.textContent}`
}).join(", ");
alert(data);
}
