示例代码：

<html>
<?php
        if( isset($_POST['cancele']) )
        {   
            $link=true;
        }
?>

<form id="eventform" name="selection" method="post">
    <div id="starttime">
        Pick event start time<br>
        <input type="text" name="startdate" id="startdatepicker" value="<?php 
     echo $curDateDisp; ?>">
        <input type="text" name="starttimehours" id="starttimehr" maxlength="2" style="width:18px" value="<?php echo $curTimeDispHr; ?>">:
        <input type="text" name="starttimeminutes" id="starttimemin" maxlength="2" style="width:18px" value="<?php echo $curTimeDispMin; ?>">

    <div id="stoptime">

        <input type="text" name="stopdate" id="stopdatepicker" value="<?php  echo $futureDateDisp; ?>">
        <input type="text" name="stoptimehours" id="stoptimehr" maxlength="2" style="width:18px" value="<?php echo $futureTimeDispHr; ?>">:

    </div>
    <div id="callinterval">
        Select call interval for event<br>
        <select name="eventInterval">
            <option value="300" <?php if($edit && $eventinterval==300) echo 'selected'; ?>>5 minutes</option>
            <option value="600" <?php if(!$edit || $eventinterval==600) echo 'selected'; ?>>10 minutes</option>
            <option value="900" <?php if($edit && $eventinterval==900) echo 'selected'; ?>>15 minutes</option>
            <option value="1800" <?php if($edit && $eventinterval==1800) echo 'selected'; ?>>30 minutes</option>

            <option value="86400" <?php if($edit && $eventinterval==86400) echo 'selected'; ?>>1 day</option>
        </select>
    </div>
    <br>
    <div>
        <input id="scheduleokbutton" type="submit" onclick="return validateForm()" action="scheduleevent.php" value="Add Event">

    </div>
    <br>
    <div>
        <input id="canceleventbutton" alt="center" name="cancele" type="submit" onclick="cancelEvent()" action="scheduleevent.php" value="Cancel Event">    
    </div>
    <br>
    <br>
    <br>
</form>
</html>

我正在尝试在按下取消按钮时更改表单数据，并且我正在使用isset（）函数。它似乎无法在Firefox和Safari浏览器中工作，它在Chrome IE11和边缘浏览器中工作正常。在firefox和safari中，由于某种原因它不会进入isset状态。有人可以帮忙吗？

isset适用于chrome，IE 11和edge但不适用于firefox和safari吗？
