setTimeout函数不location.href

Question

工作我不知道为什么这个代码不重新定向，当我使用setTimeout函数与location.href：

<?php 
if($s == 1){ 
    echo '<div class="success"><i class="fa fa-check-circle"></i><h3>Thank You!</h3> 
    Your enquiry has been sent successfully. 
    <br/> 
    We will get back to you soon!</div>'; 
} 
else{ 
    echo '<div>Your message sending failed!</div>'; 
} 

echo "<script>setTimeout(location.href = '123.php', 2500);</script>"; 
?>

setTimeout的第一个参数必须是AA功能，所以你需要把你的命令放在一个函数中。即使是这样的function(){ location.href = '123.php'; }会做：

<?php 
if($s == 1){ 
    echo '<div class="success"><i class="fa fa-check-circle"></i><h3>Thank You!</h3> 
    Your enquiry has been sent successfully. 
    <br/> 
    We will get back to you soon!</div>'; 
} 
else{ 
    echo '<div>Your message sending failed!</div>'; 
} 

echo "<script>setTimeout(function(){ location.href = '123.php'; }, 2500);</script>"; 
?>
