单击按钮时，我正在尝试增加计数。。但在我的代码中，当刷新页面时，计数会增加。。我只想在点击按钮时增加计数。。我想在刷新页面时停止计数。。当点击按钮时，代码运行良好，它会增加，但当我们刷新页面时，计数也会增加。。刷新页面时，计数不应增加。我该怎么做
<?php
$vote = $_REQUEST['vote'];
//get content of textfile
$filename = "poll_result.txt";
$content = file($filename);
//put content in array
$array = explode("||", $content[0]);
$yes = $array[0];
$no = $array[1];
if ($vote == 0)
{
$yes = $yes + 1;
}
if ($vote == 1)
{
$no = $no + 1;
}
//insert votes to txt file
$insertvote = $yes;
$fp = fopen($filename,"w");
fputs($fp,$insertvote);
fclose($fp);

您使用的是localStorage，它在刷新时不会重置。最简单的方法是在加载时重置(<body bgcolor=#5D003D> onload='localStorage.clickcount=0'>.
