Question

我有一个管理页面，其中用户更新了该号码，但是当我点击后退按钮时，它仍然显示文本框中的旧值，这是我的代码。

＆＃13;

<?php
//following code to update the ticket avaiable number
if(isset($save))
{
//To insert number into database
	Data::getupdate($ticketsavailable);	
	print('<script>window.location.href="https://ct.org/gun-drawing-nocache1/"</script>');
}
//following code for to show the available tickets on the text box
$ticketleft = "";
//this will fetch number from database
$ticketleft = Data::getticketsavailable();

}


?>

 <script type="text/javascript">    
// If persisted then it is in the page cache, force a reload of the page.
        window.onpageshow =function(event){
            if(event.persisted){        
                document.body.style.display ="none";        
                location.reload();
            }
        };
</script>
</form> 
</body>
</html>

//我使用过javascript：但它对Chrome无效我也尝试过页面上的标题仍然无法正常工作。标题（＆＃34; Expires：Thu，1981年11月19日08:52:00 GMT＆＃34;）; //过去的日期 header（＆＃34; Cache-Control：no-store，no-cache，must-revalidate，post-check = 0，pre-check = 0＆＃34;）; //HTTP/1.1 标题（＆＃34; Pragma：no-cache＆＃34;）;

如何通过单击浏览器的后退按钮强制所有Web浏览器重新加载页面？
