Call php function from JavaScript（4个答案）

关闭2分钟前。

我有一个JS清单。我想使用PHP将它保存在Mysql DB中，而没有任何用户事件。我无法将JS列表传递给php。

<script type="text/javascript">
// I have a javascript function that returns the output as below
    var result = 
      [
        {name: "Adam", age: "40", covid19: "positive"},
        {name: "Eve", age: "30", covid19: "negative"},
        {name: "David", age: "25", covid19: "positive"}
      ];
</script>

<?php
// To Do: Need to pass the result list above as an array,
//        so that I can save them individually in DB using simple for loop

   echo "<script>document.writeln(result);</script>";

  // This shows output like [object] [object] [object]....
?>

需要Ajax，您才能将数据从前端传递到后端。 Followin是做到这一点的方法。
