我遇到了一点问题。
我有一个函数叫做get_press(), 它检索最新的新闻项目。它位于插件内部：
class EWPress {
function __construct()
{
load_plugin_textdomain( \'ew\', flase, dirname( plugin_basename( __FILE__ ) ) . \'/lang\' );
add_action( \'wp_enqueue_scripts\', array( &$this, \'register_plugin_scripts\' ) );
// Add JS var ajaxurl to global namespace
add_action( \'wp_head\', array( &$this, \'add_ajax_library\' ) );
add_action( \'wp_ajax_get_press\', array( &$this, \'get_press\' ) );
add_action( \'wp_ajax_nopriv_get_press\', array( &$this, \'get_press\' ) );
}
public function get_press()
{
$args = array(
\'status\' => \'publish\',
\'post_type\' => \'press\',
\'orderby\' => \'meta_value\',
\'meta_key\' => \'press_date\',
\'order\' => \'DESC\',
\'posts_per_page\' => 2
);
$query = new WP_Query($args);
return($query->posts);
//echo json_encode($query->posts);
//die();
}
}
如果我通过以下方式在模板文件中直接调用此函数：
echo EWPress::get_press() 输出完全正常：
Array
(
[0] => WP_Post Object
(
[ID] => 229
[post_author] => 1
[post_date] => 2013-01-18 00:29:58

)
)
为了发出AJAX请求，我：
注释掉echo EWPress::get_press() 在模板级别上，注释掉return $query->posts 在get_press() 功能取消注释echo json_encode($query->posts)die();order = \'ASC\' 或\'DESC).
AJAX功能：
(function($) {
$(document).ready(function(){
$.ajax({
url: ajaxurl,
type: \'POST\',
dataType: \'json\',
data: {action: \'get_press\'},
complete: function(xhr, textStatus) {
//
},
success: function(data, textStatus, xhr) {
console.log(data);
},
error: function(xhr, textStatus, errorThrown) {
//called when there is an error
}
});
});
})(jQuery);

有人知道为什么会这样吗？
