javascript - Codeigniter 中的 JQuery Ajax POST 不起作用

Question

我在 codeigniter 中使用 jquery ajax post 时遇到问题，我遇到的问题是当单击提交按钮时，发生错误

这是我的代码

home.js

form.on('submit', function(e){
    e.preventDefault();
    var fields = {};
    form.find('input','textarea').each(function(index, el){
        el.readOnly = true;
        fields[$(el).attr('name')] = $(el).val();
    });

    // send request to server
    $.ajax({
        type: 'POST',
        url: '/home/tryproduct/',
        data: fields,
        dataType: 'json'
    })
    .done(function(result){
        if(result.error === false){
            alert(result.message);
        } else {
            alert(result.message);
        }
        form.find('input','textarea').each(function(index, el){
            el.readOnly = false;
        });
        form[0].reset();
    });
});

这是我的观点

<form class="row" name="free-trial">
                    <div class="col-sm-6 col-xs-12">
                        <div class="form-group">

                    </div>
                </form>

Controller

public function tryproduct(){
    $this->view = FALSE;
    if ($_SERVER['REQUEST_METHOD'] !== 'POST') return;
    $data = array(
        'firstname' => $this->input->post('firstname'),
        'lastname'  => $this->input->post('lastname'),
        'position'  => $this->input->post('position'),
        'company'   => $this->input->post('company'),
        'address'   => $this->input->post('address'),
        'phone'     => $this->input->post('phone'),
        'email'     => $this->input->post('email'),
        'notes'     => $this->input->post('notes')
    );
    $id = $this->trial_request->insert($data);
    if(!$id){
        echo json_encode(array(
            'error' => true,
            'message' => 'error register product trial'
        ));
    } else {
        echo json_encode(array(
            'error' => false,
            'message' => 'success register product trial',
            'user' => $data,
        ));
    }
}

先谢谢大家了

我认为问题出在

url: '/home/tryproduct/'

使用base_url()来制作ajax url路径的url。它会起作用的。
