我是 PHP 和 javascript 编程的新手。我有一个使用 PHP 回显的链接。

<?php .....echo "<td><font class='calendar'><a onclick='showevent($currentday)' href='#'>". $currentday. "</a></font></td>"; ....?>

我需要从上面的链接调用函数 showevent()。

<script>

function showevent($day){
     $thisday = $day;
     document.showevent.submit();
}

</script>

该函数将提交如下表格：

<form action="./event.php" name="showevent" method="post">
    <input type="hidden" name="page" value="showevent" /> 
    <input type="hidden" name="month" value="<?php echo $cMonth;?>" /> 
    <input type="hidden" name="year" value="<?php echo $cYear; ?>" />
    <input type="hidden" name="day" value="<?php echo $thisday; ?>" />
</form>

javascript函数不起作用。任何人都可以帮助建议和指导我吗？

    document.showevent.submit();
}</script>

<script>
function showevent(day)
{
    alert(day); // test if it triggers
    document.showevent.day.value = day;
    document.showevent.submit();
    return false;
}
</script>

还：

<a onclick='javascript: showevent($currentday);'

应该：

<a onclick='return showevent($currentday);'

请在脚本标签中添加类型并尝试

<script type="text/javascript">

function showevent($day){
     $thisday = $day;
     document.showevent.submit();
}

</script>

希望这可以帮助你解决你的问题......
