我正在编程约会刨床，但仍然在努力解决javascript没有生成事件并以纯文本方式打印代码的问题，所以起初我有一个php函数从sql获取所有约会数据库并生成javascript代码

<script>
    function getEventData() {
    <?php
        function showAppointments($von, $bis){
            $link = OpenDB();
            try {
            $query = 'SELECT termin_id, client, dateFrom, dateTill, title, descri FROM termin WHERE dateFrom BETWEEN :von AND :bis';
            $statement = $link->prepare($query);
            $statement->bindValue(':von', $von, PDO::PARAM_STR);
            $statement->bindValue(':bis', $bis, PDO::PARAM_STR);
            $statement->execute();

            $row = $statement->fetchAll();
            }
            catch (PDOException $e) {
                p($e);
            }
            CloseDB($link);

            return $row;
        } 
    if(empty($von) && empty($bis)) {
                $von = date("Y.m.j",strtotime("monday this week"));
                $bis = date("Y.m.j",strtotime("sunday this week"));
             }
            if(isset($_POST['last_week'])){
                $von = date("Y.m.j",strtotime("previous monday"));
                $bis = date("Y.m.j",strtotime("previous sunday"));
             }
            if(isset($_POST['next_week'])){
                $von = date("Y.m.j",strtotime("next monday"));
                $bis = date("Y.m.j",strtotime("next sunday"));
            }
            $rows = showAppointments($von, $bis);

      echo "const appointments = [";
      for($i = 0; $i < sizeof($rows); $i++) {
          $columns = array_values($rows[$i]);
          echo "[";

          for($j=0; $j< sizeof($columns); $j++){          
             echo "'".$columns[$j]."'";
             if( $j < sizeof($columns)-1) echo ",";
          }
           echo "]";

    if( $i < sizeof($rows)-1) echo ",";    
        }

            echo "];";
    ?>
then all events are generated by jquery and returned

    return { 

             events:[

            $.each(appointments, function(index, row){

                    eval("{'id':"+ row[0] + ",'client':"+ row[1] +",'start':" + new Date(row[2])+",'end': "+ new Date(row[3]) +",'title':'"+ row[4] +"','description':'"+ row[5] +"'}");

            });

            ]}}
</script>

foreach中的代码以纯文本形式打印，如何解决问题？它实际上应该打印像

这样的东西

{'id':1, 'start': new Date(year, month, day, 12), 'end': new Date(year, month, day, 13, 30),'title':'Lunch with Mike'}

Answer 1

你应该在事件外部尝试Jquery.each，然后使用eval（Array.join）;在JavaScript中，这应该工作

jquery在foreach上生成事件
