Question

我试图使用cakephp中的ajax从数据表中获取数据。我发送了一个名为的数据，并希望获取所有记录。这就是我尝试的方式：

ajax:
    $("#Designation").click(function(){
                alert($("#Designation").val());

                var data = {
                    "Designation": $("#Designation").val()
                }

                $.ajax({
                    type:"POST",
                    dataType: "JSON",
                    url: '<?php echo Router::url(array('controller'=>'DynamicForm','action'=>'getbulkoptions')); ?>',
                    data:data,
                    success:function(data){
                        alert("success");
                        console.log(data);
                        if(data.fieldid=="0"){
                            //MyNotif.Show(data.message,"warning");
                            alert("Field Exists");
                        }else{
                            $("#mymodal").modal('hide');
                            //MyNotif.Show(data.message,"success"); 
                            //window.location.reload();
                            alert("Bulk List");
                        }
                    },
                    error:function(XMLHttpRequest, textStatus, errorThrown){
                        console.log(XMLHttpRequest.responseText);
                    }
               });
            });

这是我尝试与数据库通信的方式：

DynamicFormController:
<?php

namespace App\Controller;
session_start();
use App\Controller\AppController;
use Cake\ORM\TableRegistry;


class DynamicFormController extends AppController {
public function getbulkoptions(){
        $optionvalue = $this->request->data('Designation');
        $designation = TableRegistry::get ('Field');

        $result = $designation->getbulkoptions($optionvalue);
        echo json_encode($result);
    }
}
    ?>

FieldTable:
<?php
namespace App\Model\Table;

use Cake\ORM\Table;

use Cake\Datasource\ConnectionManager;

class FieldTable extends Table {
    var $name = 'FieldTable';
public function getbulkoptions($designation){
        $conn = ConnectionManager::get('default');
        $stmt = $conn->prepare( "CALL proc_getbulkoptionslist (:tid)");
        $stmt->bindValue( ':tid', $designation);
        $stmt->execute ();
        return $stmt->fetchAll ('obj');
    }
}

问题是，我得到了适当的回应。我得到了我想要的数据，但是数据正在ajax的错误函数中打印出来。我希望它成为成功的功能。我不知道上面的代码有什么问题。当我试图打印错误时，我得到了这个：

SyntaxError: JSON.parse: unexpected non-whitespace character after JSON data at line 1 column 364 of the JSON data
Stack trace:
n.parseJSON@http://localhost/payrollengine/js/jquery.js:4:16508

y@http://localhost/payrollengine/js/jquery.js:4:22274
.send/c@http://localhost/payrollengine/js/jquery.js:4:26750

我在错误功能中尝试了这个并尝试打印出来，我得到了这个回复：

    error:function(XMLHttpRequest, textStatus, errorThrown){
                            console.log(XMLHttpRequest.responseText);
                        }
response:
        [{"fieldvalueid":"1","value":"Manager"},{"fieldvalueid":"2","value":"Project Manager"},{"fieldvalueid":"3","value":"Software Engineer"},{"fieldvalueid":"4","value":"Senior Software Engineer"},{"fieldvalueid":"5","value":"Associate Software Engineer"},{"fieldvalueid":"28","value":"sample"},{"fieldvalueid":"29","value":"azhagu"},{"fieldvalueid":"37","value":"t"}]null

我不知道代码有什么问题。有人可以帮我解决这个问题吗？

将json标头添加到控制器功能中：

header('Content-Type: application/json');
echo json_encode($result);

尝试从db

返回一个关联数组

->fetchAll('assoc');

数据是在ajax的错误函数中获得的
