js对ajax返回数组的处理介绍

function ajaxcheckedlessonsAction(){
        //3583 语文 8班
        //1500 语文 9班
        //2717 物理 8班
        //1612 物理 9班

        $whereLessons['lessons.id IN(?)'] = array(3583, 1500, 2717, 1612);
        $daoLessons = new dao_lessons();
        $alllessons = $daoLessons->getLessons($whereLessons);
        //print_r($alllessons);exit;
        $lessonsChecked = array();
        foreach ($alllessons as $lessons) {
            if ($lessons['id'] == 3583) {
                $lessonsChecked['8yuwen'] = $this->verifyCheckedLessons($lessons['startime'], $lessons['endtime']);
            } elseif ($lessons['id'] == 1500) {
                $lessonsChecked['9yuwen'] = $this->verifyCheckedLessons($lessons['startime'], $lessons['endtime']);
