控制器：測試/send_mail_account()public function send_mail_account() {    $usertype = $this->session->userdata("usertype");    $loginuserID = $this->session->userdata("loginuserID");    $adminID = $this->session->userdata("adminID");    $email = $this->session->userdata("email");    $username = $this->session->userdata("username");    if($usertype == "Accountant")     {        $totalData = $this->invoice_m->get_order_by_student_by_join_Count($adminID);        $totalFiltered = $totalData;        $data['posts'] = $this->invoice_m->make_datatables($adminID);        $this->load->library('email');        $config=array(        'charset'=>'utf-8',        'wordwrap'=> TRUE,        'mailtype' => 'html'        );        $this->email->initialize($config);        $html = $this->load->view('emailTemplates/feeupdation/feeupdationaccountant', $data , true);        $this->email->set_mailtype("html");        $this->email->from($email, $username);        $this->email->to('xyz@gmail.com');        $this->email->subject("Student Account List");        $this->email->message($html);        $this->email->send();    }     else     {        $this->data["subview"] = "error";        $this->load->view('_layout_main', $this->data);    }}看法：<script>    function checkDate() {        var date = new Date();        console.log(date.getDay());        console.log(date.getHours());        console.log(date.getMinutes());        console.log(date.getSeconds());        if(date.getDay() === 3 && date.getHours() ===13 && date.getMinutes() === 33 && date.getSeconds() === 1) {            window.location.replace("<?php echo base_url(); ?>test/send_mail_account");        }    }    var dateLoop = setInterval(function() {        checkDate();    },5000);</script>在這段代碼中，我有一個函數(shù)，即send_mail_account當我的腳本運行時我想要的位置，然后它將我重定向到控制器函數(shù)上。在這里，5 second腳本運行后會發(fā)生什么，當我使用它alert()代替window.location.replace()它時會發(fā)生什么，但是當我運行時window.location.replace()它不起作用。我不知道為什么我做錯了什么？請幫我。
