Question

我运行一个ajax请求tQuery调用一个php函数，每次调用它都有效，我不是说编写的代码应该工作，因为它是正确的，但它的工作原理是因为我可以看到数据库中的输出。但是request.fail(function(jqXHR, textStatus){alert('AJAX Error: '+ textStatus);});会返回错误（parseerror），这是我的代码：

$('#createtk').click(function(){
                var tit=$('#title').val();
                var prio=$('#priority').val();
                var wsurl=$('#wsurl').val();
                var dep=$('#dep').val();
                var message=CKEDITOR.instances.message.getData().replace(/\s+/g,' ');
                if(tit.replace(/\s+/g,'')!='' && prio.replace(/\s+/g,'')!='' && dep.replace(/\s+/g,'')!='' && wsurl.replace(/\s+/g,'')!='' && message.replace(/\s+/g,'')!=''){
                    var request= $.ajax({
                        type: 'POST',
                        url: '../php/function.php',
                        data: {act:'create_ticket',tit:tit,prio:prio,dep:dep,wsurl:wsurl,contp:$('#contype').val(),ftpus:$('#ftpus').val(),ftppass:$('#ftppass').val(),message:message},
                        dataType : 'json',
                        success : function (data) {
                            alert('1');
                            if(data[0]=='Created'){
                                alert('2');
                                window.location = "<?php echo dirname(curPageURL()); ?>";

                            }
                            else
                                alert(data[0]);
                        }
                    });
                    request.fail(function(jqXHR, textStatus){alert('AJAX Error: '+ textStatus);});
                }
                else
                    alert('Form Error - Empty Field');
            });

这是php函数（对不起该演示文稿，我把这只是为了获取信息，因为它工作的exe）：

else if(isset($_POST['act']) && isset($_SESSION['name']) && $_POST['act']=='create_ticket'){ //controllare

$prio=(is_numeric($_POST['prio']))? $_POST['prio']:exit();

$wsurl=(preg_replace('/\s+/','',$_POST['wsurl'])!='')? htmlentities(preg_replace('/\s+/',' ',$_POST['wsurl']),ENT_QUOTES,'UTF-8'):exit();

    }
    else
        echo json_encode(array(0=>mysqli_stmt_error($stmt)));
    $mysqli->close();
}
else
    echo json_encode(array(0=>'Empty Message'));
}

该函数调用另一个PHP函数（retrive_avaible_operator）retrun一个值，我想知道这是不是问题，请问AJAX / PHP是否将此信息作为最终输出？祝贺提前

我的上帝是很多嵌套的ifs。您是否考虑过使用名为例外的内容来生成错误？

我无法检查PHP脚本的返回值。但是，jQuery需要一个json返回（因为你将dataType设置为），如果它得到任何其他内容将会失败...包括一个空字符串。

AJAX请求返回错误，但PHP函数工作
