如何将参数从JavaScript传递到Codeigniter中的控制器？

Question

我想将参数从javascript传递到codeigniter控制器。 这个怎么做。 我的JavaScript文件如下

user.js的

function confirmcourse(){  
     $('.confirm').unbind("click");
     $('.confirm').on("click",function(e){
         var courseId=$(this).attr('data-id');
         $.ajax({
            type: "POST",
            data:{cid: courseId},
            url: urljs+"user/Teach_controller/confirmcourse",
            dataType:'json',
        }).done(function( data ) {
            if(data.result=1){
                window.location.assign(urljs+"user/Learn_controller");
            }else{
                noty({ text: 'Something went wrong during process please try again',type: 'error',modal:true,timeout:1000});
                window.location.reload();
            }
        });
    });
}

Learn_controller

public function index($course_type ==''){
        $id=$this->session->userdata('cp_userid');
        $userdetails=$this->Usermodel->getuserdetails($id);
        $data['userdetails']=$userdetails;
        $result=$this->Usermodel->currentlearningcourses($id);
        $data['details']=$result;
        $data['content']=$this->load->view("user/currentlearningcourses",$data,true);

        if($course_type == 'teaching'){
            $result = $this->Usermodel->teachingcourses($id);
            $data['details'] = $result;
            $data['content'] = $this->load->view("user/teachingcourses",$data,true);
        }

        $data['title']='My Courses';            
        $headerContent = $this->load->view("user/layout",$data,true);
        $this->render($headerContent);
    }

我想将该教学参数从javascript文件索引到Learn_controller。

您应该使用$_POST['cid']在控制器中阅读它

但是ajax调用的控制器响应不能是视图，这是一个JSON是一个好习惯

$this->output->set_content_type('application/json');
$this->output->set_output(json_encode($data));

在你的情况下$data['result'] = 1;
