如何在jQuery中获取父div属性值？

Question

I need data-offerId of parent div but it's not working properly. Please suggest me.

HTML

<div class="rows" data-offerid="123487 ">15<span class="mth">.– /mth</span><span class="clear-row"></span></div>
<div class="rows" data-offerid="123486 ">15<span class="mth">.– /mth</span><span class="clear-row"></span></div>

Jquery:

 $('.clear-row').click(function(){
     var offers = $('.clear-row').parent().attr('data-offerid');
     console.log(offers);
 });

Answer 1

Inside the handler, you should be using this not repeating the selector .clear-row

$('.clear-row').click(function(){
   var offers = $(this).parent().attr('data-offerid');
   console.log(offers);
});

You can also use data() instead of attr()

var offers = $(this).parent().data('offerid');

Answer 2

Use this inside your click event, to target the cleararrow element your clicked on

$(this).parent().attr('data-offerid')

$('.clear-row').click(function() {
  var offers = $(this).parent().attr('data-offerid');
  console.log(offers);
});

Working example

 $('.clear-row').click(function() { var offers = $(this).parent().attr('data-offerid'); console.log(offers); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="rows" data-offerid="123487 ">15<span class="mth">.– /mth</span><span class="clear-row">clear</span></div> <div class="rows" data-offerid="123486 ">15<span class="mth">.– /mth</span><span class="clear-row">clear</span></div> 

Answer 3

Here you go with one more way using jQuery closest method https://jsfiddle.net/464g5hzq/

 $('.clear-row').click(function(){ var offers = $(this).closest('div.rows').data('offerid'); console.log(offers); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="rows" data-offerid="123487 ">15<span class="mth">.– /mth</span><span class="clear-row"></span></div> <div class="rows" data-offerid="123486 ">15<span class="mth">.– /mth</span><span class="clear-row"></span></div> 

Instead of using .attr to get the data attribute , please use .data(attribute-name); if you have data attribute like data-offerid .

Hope this will be useful to you.

Try this way:

$('.clear-row').click(function(){
    var offers = $(this).parent().attr('data-offerid');
    console.log(offers);
});

//OR

var offers = this.parentNode.getAttribute("data-offerid");   // plain javascript
