在我的wordpress主题中，我试图打印多个custom fields 使用ajax的帖子数量。首先我得到title 正确使用ajax live搜索的帖子，现在需要在单击任何帖子标题后显示帖子数据。

之后Click 在任何title 在live search中，它会在同一页面上显示该帖子的自定义字段？？

HTML:

<h2><a href="#" name="metakey" id="metakey"><?php the_title();?></a></h2>
<div id="viewspec"> Meta key result here </div>

Funtion:

<?php
add_action(\'wp_ajax_data_fetchmeta\' , \'data_fetchmeta\');
add_action(\'wp_ajax_nopriv_data_fetchmeta\',\'data_fetchmeta\');
function data_fetchmeta(){

$the_query = new WP_Query( array( \'s\' => esc_attr( $_POST[\'metakey\'] ), \'post_type\' => \'post\' ) );
if( $the_query->have_posts() ) :
    while( $the_query->have_posts() ): $the_query->the_post(); ?>       
<p>
    <?php echo get_post_meta( get_the_ID(), \'brand\', true );?>
    <?php echo get_post_meta( get_the_ID(), \'price\', true );?>
    <?php echo get_post_meta( get_the_ID(), \'cpu\', true );?>
    <?php echo get_post_meta( get_the_ID(), \'ram\', true );?>
</p>
  <?php endwhile;
  wp_reset_postdata();  
  endif;
  die();
}
?>

Script:

<script type="text/javascript">
function h2 a{

jQuery.ajax({
    url: \'<?php echo admin_url(\'admin-ajax.php\'); ?>\',
    type: \'post\',
    data: { action: \'data_fetchmeta\', metakey: jQuery(\'#metakey\').onclick() },
    success: function(data) {
        jQuery(\'#viewspec\').html( data );
    }
});
}
</script>

AJAX live search: working

<input type="text" name="keyword" id="keyword" onkeyup="fetch()"></input>
<div id="datafetch">  Search result here  </div>

<?php
// add the ajax fetch js
add_action( \'wp_footer\', \'ajax_fetch\' );
function ajax_fetch() {
?>
<script type="text/javascript">
function fetch(){
jQuery.ajax({
    url: \'<?php echo admin_url(\'admin-ajax.php\'); ?>\',
    type: \'post\',
    data: { action: \'data_fetch\', keyword: jQuery(\'#keyword\').val() },
    success: function(data) {
        jQuery(\'#datafetch\').html( data );
    }
});
}
</script>
<?php
}

// the ajax function
add_action(\'wp_ajax_data_fetch\' , \'data_fetch\');
add_action(\'wp_ajax_nopriv_data_fetch\',\'data_fetch\');
function data_fetch(){
if (  esc_attr( $_POST[\'keyword\'] ) == null ) { die(); }
$the_query = new WP_Query( array( \'posts_per_page\' => -1, \'s\' => esc_attr(     $_POST[\'keyword\'] ), \'post_type\' => \'post\' ) );
if( $the_query->have_posts() ) :
    while( $the_query->have_posts() ): $the_query->the_post(); ?>

        <h2><a href="#" name="metakey" id="metakey"><?php the_title();?></a> </h2>

    <?php endwhile;
    wp_reset_postdata();  
    endif;
    die();
    }
