Question

我需要将一个查询从我的codeigniter传递到javascript控制台日志，以便在javascript中查看我的数据，所以我有我的模型

public function getChartData()
{
    $this->db->select('Month,Completion_Percentage');
    $this->db->from('monthlyreport');
    $this->db->order_by('Project_No', 'asc');    
    $query = $this->db->get();
    $result = $query->result();

    $data_List = array();
    foreach ($result as $row) 
    {
    $data_List[] = $row->Month;
    $data_List[] = $row->Completion_Percentage;
    }
    return $data_List;

}

我的控制员：

public function monthlyReport()
{
    $this->load->view('monthlyReport');
}

和内部脚本：

<script type="text/javascript">
        $(document).ready(function){
        $.ajax({
        method: 'GET',
        url: '<?php echo site_url('main/chart_api')?>',
        success: function (data) {
            console.log(data);
        },
        error:function(data) {
            console.log(data);
        } 
        });
    }

应该去哪里：

public function chart_api()
{
    $data_List = $this->foo_pro->getChartData();
    echo json_encode($data_List);
}

它显示了Uncaught SyntaxError：Unexpected token

的控制台错误

您需要在Ajax中添加dataType：“JSON”，并且

you have echo json_encode($data_List); 
not return json_encode($data_List);

$.ajax({
        method: 'GET',
        dataType:"JSON",
        url: '<?php echo site_url('main/chart_api')?>',
        success: function (data) {
            console.log(data);
        },
        error:function(data) {
            console.log(data);
        } 
        });

从codeigniter查询到javascript日志
