PHP 404判斷 與 js 404判斷

php判斷404:


$url = home_url()."/wp-content/themes/twentythirteen/pic/".$result['pic'];$headers = @get_headers($url);if(strpos($headers[0],'404') ){$url=home_url()."/wp-content/themes/twentythirteen/pic/default.png";}


js判斷404:


var pic_url ="/wp-content/themes/twentythirteen/pic/"+data[i].pic;$.ajax({url:pic_url,error:function(xhr, error, ex){if (xhr.status == '404') {pic_url = "/wp-content/themes/twentythirteen/pic/default.png";}},success:function(){pic_url = pic_url;}});
