Question

如何在重新加载/刷新网站时运行javascript函数（数学计算）？有没有一种简单的方法可以做到这一点？

以下简单计算的结果应该在。）网站刷新时刷新，b。）当任何数学值发生变化时。

我已经尝试过onload而不是onclick，但这并没有改变任何东西。

我建立了一个实时网站，请看这里：

http://90.153.112.5:8888/djdp42Bjjr39399nfjjj39xleit832991vnJ39921/live/test.php

和代码（test.php）：

<?php
require_once("dbcontroller.php");
$db_handle = new DBController();
$sql = "SELECT * from strategy_sheets";
$faq = $db_handle->runQuery($sql);
?>
<html>
    <head>
        <script src="http://code.jquery.com/jquery-1.10.2.js"></script>
        <script>

        function showEdit(editableObj) {
            $(editableObj);
        } 

        function saveToDatabase(editableObj,column,id) {
            $(editableObj);
            $.ajax({
                url: "saveedit.php",
                type: "POST",
                data:'column='+column+'&editval='+editableObj.innerHTML+'&id='+id,
                success: function(data){
                    $(editableObj);
                }        
           });
        }

        </script>
   </head>
<meta http-equiv="content-type" content="text/html; charset=utf-8">
<style>}
</style>
<body>
<table class="tbl-qa">

<tr>
    <td >DESCRIPTION:</td>
         <?php
          foreach($faq as $k=>$v) {
          ?>

        <td contenteditable="true" id="Event" onBlur="saveToDatabase(this,'event','<?php echo $faq[$k]["id"]; ?>')" onClick="showEdit(this);"><?php echo $faq[$k]["event"]; ?></td>

        <?php
        }
        ?>

        </table>

<table class="tbl-qa">
      <tr>
    <td>VALUE 1:</td>
          <?php
          foreach($faq as $k=>$v) {
          ?>

        <td contenteditable="true" id="Tank" size="2" oninput="output();output2();output3();" onBlur="saveToDatabase(this,'Tank','<?php echo $faq[$k]["id"]; ?>')" onClick="showEdit(this);"><?php echo $faq[$k]["Tank"]; ?></td>

        <?php
        }
        ?> 
    <td>VALUE 2:</td>
          <?php
          foreach($faq as $k=>$v) {
          ?>

        <td contenteditable="true" id="Spritverbrauch" size="2" oninput="output();output3();" onBlur="saveToDatabase(this,'Spritverbrauch','<?php echo $faq[$k]["id"]; ?>')" onClick="showEdit(this);"><?php echo $faq[$k]["Spritverbrauch"]; ?></td>

        <?php
        }
        ?> 
   </tr>
   <tr>
  <p></p>
<td>RESULT: </td>

    <td><a id="StintlangeRd" onload="output();output3();"></td>
    </tr>
</table>
<script type="text/javascript">

function output(){

    var value2 = document.getElementById('Tank').textContent;
    var value3 = document.getElementById('Spritverbrauch').textContent;
    document.getElementById('StintlangeRd').innerHTML = (parseFloat(value2) / parseFloat(value3)).toFixed(2);

}

</script>

<script type="text/javascript">
   setTimeout(function(){
       location.reload();
   },60000);
</script>
