You need to pass the product id from ajax request. Then in your php callback function you can get product object from that id using woocommerce function.

/ /Get $product object from product ID
$product = wc_get_product( $product_id );

You need to register the ajax endpoint as below in your plugin 

<pre><code> add_action('wp_ajax_myFunction','myFunction');
</code></pre>

then from your javascript you can do following 

<pre><code> var postData = {
 'product-id': productId,
 'action':'myFunction'
 };

 $.ajax({
 'type':'POST',
 'url': ajaxurl,
 'dataType':'json',
 'cache':false,
 'data':postData,
 success: function(response)
 {

//more stuffs do ot 

 },
 error: function(xhr, textStatus, errorThrown)
 {
 // handle error 
 }

 }
</code></pre>

Then at backend function myFunction

<pre><code> $postItems = filter_input_array(INPUT_POST, ['product-id' =&gt; 'string']);

//$postItems will contain product-id which you can use to do more things 

// this gives $product object with public method like get_title

 $product = wc_get_product( $product_id );

 $name = $product-&gt;get_title();

 wp_send_json_success( array('name'=&gt;$name), 200);
 exit();
</code></pre>

Hope this helps!

I am trying to build a simple plugin that inserts a simple AJAX powered button into a WooCommerce product page. Upon the press of the button, I would like to return the current product data to my Javascript code to be handled on the front end. 

This is the callback function that gets executed upon click. 

<blockquote>
 I get error: wp-admin/admin-ajax.php 500 (Internal Server Error)
</blockquote>

<pre><code>function myfunction() {
 //gets executed;
 global $product;
 $name = $product-&gt;get_name();
 echo $name;
 wp_die();
 }
</code></pre>

In debug.log it becomes apparent that the global $product variable is not available: PHP Fatal error: Uncaught Error: Call to a member function get_name() on null.

Notes:

<ul>
<li><code>global $product; $product-&gt;get_name()</code> works in other php functions
not called through AJAX.</li>
<li><code>myfunction()</code> is successfully called and the response is correctly handled in the JQuery request. If I echo a hardcoded 'string' instead, it works!</li>
</ul>

Anyone has encountered this before and found a fix ?
