Get post id and pass it to jquery

Hello. I registered a custom column in the list of posts, opposite to each post I should have a select tag, but I need to assign each id to the id of the post opposite which it is displayed. How can I do that? It is advisable to do this through jquery
My registered column

function equipment_column_display( $column_name, $post_id ) {
if ( 'equip' != $column_name )
return;
$equip = get_post_meta($post_id, 'source_link_custom_field', true);
if ( !$equip )
$equip = rel_select_post().'<a id="savebtn" class="save-sel" >Save</a>';
echo $equip;
}
add_action( 'manage_posts_custom_column', 'equipment_column_display', 10, 2 );

Function that prints from the database a select
`function rel_select_post(){
global $wpdb;
$table_cat = $wpdb->prefix . ‘rel_cat’;
$rel_cat = $wpdb->get_col(“SELECT name FROM $table_cat”);
?>
<select name=”cat-select” id=”category-select”>
<option value=””>Select category</option>
<?php
foreach($rel_cat as $key => $value):
$key = 1;
echo ‘<option value=”‘.$value.'”>’.$value.'</option>’;
endforeach;
?>
</select>
<?php
} `
