AJAX函数调用提交按钮在PHP CodeIgniter

标签： javascript php jquery ajax

我正在研究CI项目，因为我正在datatables中加载数据库中的数据并在该数据表上应用filters。当我从drop-down listbox中选择一个值并点击过滤按钮时，它会过滤数据，但下拉列表框中的值会重置。为此，我尝试使用AJAX function加载数据，但我的AJAX call无法处理按钮点击事件。

以下是我的代码：

控制器： 

public function index()
{
    $user = $this->ion_auth->user()->row();
    $data['username'] = $user->username;

    $data['user_id'] = $user->id;
    $user_id = $user->id;
    $data['groupId'] = $this->l->groupId($user_id);
    $data['group'] = $data['groupId']['0']->group_id;
    //$propId = $this->input->post('property_id');
    $propertyType=$this->input->post('property_type');
    $area=$this->input->post('area_id');
    $stageId=$this->input->post('property_status');

    $clustersID['cluster']=$this->input->post('cluster_id');

    if(!empty($clustersID['cluster'])){
      // Array contains values, everything ok
      $clusterString = implode(',', $clustersID['cluster']);
    } else {
      // Array is empty
      $clusterString = 0;
    }

    if ($propertyType =='') {
        $propertyType=0;
    }
    if( $area ==''){
        $area =0;
    }
    if($clusterString == ''){
        $clusterString=0;
    }
    if ($stageId == '') {
        if($data['group']==1)
        {
            $stageId=0;
        } else {
            $stageId=4;
        }
    }
    $propDetail = $this->input->post('propDetail');

    $data['areas'] = $this->p->area();
    $data['clusters'] = $this->p->cluster();
    $data['property_stage'] = $this->p->selectPropertyStage();
    //$data['clusters'] = $this->p->clusterAll($area);
    $data['title'] = 'Property List';
    $data['property_type'] = $this->p->selectPropertyType();
    $data['properties'] = $this->p->getPropertyByAreaCluster($propertyType, $area, $clusterString, $stageId);

    $data['property'] = json_encode($data['properties']);

    $data['prop'] = json_decode($data['property']);

    //$data['props'] = $this->p->PropView($propId);
    $this->load->view('template/header', $data);
    $this->load->view('Property/property_view', $data);
    $this->load->view('template/footer');
}

型号： 

public function getPropertyByAreaCluster($propertyType, $area, $clusterString, $stageId)
{
    $query = $this->db->query("call fetch_propertyType_Area_Cluster_Stage($propertyType,$area,'$clusterString',$stageId)");
    if ($query) {
        $data = $query->result();
        $query->next_result(); 
        $query->free_result();
        return $data;
    }else{
        return false;
    }
}

我用谷歌搜索了它，但没有得到正确的结果，欢迎任何形式的帮助。提前谢谢。

您可以尝试使用Ajax网址：base_url('')到site_url('')
