我正在尝试根据我的 mysql 表生成 javascript 函数并运行该生成的函数。当新的多边形坐标添加到数据库时，我想更新我的谷歌地图。

文件上传和转换完成时启动加载功能：

function reloadMaps() {
    console.log("reloadMaps");
    //$.get("pages/fields.php", function(data){$('#content').html(data);});
    $.get("addMaps.php", function(data){$('#mapCoordsInclude').html(data);});
    addMaps();
}

addMaps.php 文件：

<script type="text/javascript">
function addMaps(){
clearMap();


console.log("paleistas update");
<?php



include "dbConfig.php";
// $r = mysql_query("SELECT `fields`.id as id,  `fields`.coordinates as coordinates, `seedings`.culture_id as culture_id, `cultures`.color as color FROM `fields` INNER JOIN seedings ON `seedings`.field_id = `fields`.id INNER JOIN cultures ON `seedings`.culture_id = `cultures`.id where `fields`.farm_id = '4'" );
$r = mysql_query("SELECT id, coordinates from fields where coordinates !='' and farm_id = 4");   


$fields = array();
while($field = mysql_fetch_assoc($r)){
    $fields[$field['id']] = $field;  
$cord = explode(';', $field['coordinates']);
unset($cord[count($cord)-1]);

echo "console.log(\"Naujausias laukas su koordinatemis ".$field['id']."\");\n";
echo "var laukas".$field['id'].";\n";


echo 'var polygonCoords = [';

      foreach ($cord as $key => $c) {
        if($key == count($cord)-1)
          echo "new google.maps.LatLng(".$c.")";
        else
          echo "new google.maps.LatLng(".$c."),";
      }

      echo "];\n";
      echo "laukas".$field['id']." = new google.maps.Polygon({
  paths: polygonCoords, strokeColor: '#000000', strokeOpacity: 0.8, strokeWeight: 2, fillColor: '#000000', fillOpacity: 0.35, id: ".$field['id']." }); laukai.push(laukas".$field['id'].");\n";
    }
    ?>

<?php
echo"\n";
  foreach($fields as $key => $field)
  {
  echo "  laukas". $field['id'].".setMap(map); google.maps.event.addListener(laukas".$field['id'].", 'click', showFieldInfo);\n";
  }
?>
}


function showFieldInfo(event) {
if (document.getElementById('fields') != null) {
      //alert(this.id);
      var page = "pages/showField.php?id=";
      page += this.id;
      $.get(page, function(data){
        $('#content').html(data);
      });
    }
}

</script>

当我触发此脚本时，它会自动运行，将坐标添加到 BD（一个单独的函数），所有 addMaps.php 都会运行，但 SELECT 语句看不到新插入的数据。如果我通过再次单击上传表单再次运行它，它运行良好。

如果我在第一次上传后从 db 中删除插入的坐标，然后再次运行上传 - 一切正常。

有任何想法吗？
