Question

What is the process for accessing the data attributes of div elements and then transferring them to a cookie?

Although this question may have been answered before, I couldn't find a specific solution.

Imagine I have the following div elements...

<div class="listings-area">

<div itemtype="http://schema.org/Product" itemscope="">
<a class="listing"  data-id="D_2781467">blah blah </a>
some more blahj blah text here 
</div>

<div itemtype="http://schema.org/Product" itemscope="">
<a class="listing"  data-id="D_2781445">blah blah </a>
some more blahj blah text here 
</div>

.......................
.......................
</div>

I am looking to extract all the data-id attributes from these elements, store them in an array, and then pass them along in a JavaScript cookie

If I try something like

$('a.listing').attr('data-id')

I only obtain the data id of the first element. How can I retrieve all the data ids and add them to an array?

Answer №1

To extract data values from elements, you can utilize the .map() method:

var idArr = $('a.listing').map(function() {
    return $(this).attr('data-id');    
}).get();

After obtaining the data values, you can save them in cookies by using:

$.cookie("example", idArr);

This process is particularly handy when working with the jQuery cookie plugin.

Utilize the .data() method to retrieve data attributes:

$('a.listing').data('id');

To access all data attributes, iterate through them using .each():

var arr = $.cookie('somecookiename').split(', '); // Splitting a string into an array
$('a.listing').each( function(){
   arr[i] = $(this).data('id') // Converting string array entries to dataids
});

Another way to achieve this is by utilizing a for loop. Check out the demo here

<div itemtype="http://schema.org/Product" itemscope="" class="ListingS">
        <ul>
            <li>
                <a class="listing"  data-id="D_2781467">blah blah </a>
                <p>some more blahj blah text here </p>
            </li>
            <li>
                <a class="listing"  data-id="D_2781445">blah blah </a>
                <p>some more blahj blah text here </p>
            </li>
        </ul>
    </div>
    <script>
$(function(){
    var liLength = $('.ListingS').find('a').length;
    var liDom = $('.ListingS').find('a');
    for (var i = 0; i < liLength; i++ ) {
        console.log( "attempting " + i + liDom.eq(i).attr('data-id'));
    }
})
