这样写可以正常跳转:

<code>echo "<script>";
echo "window.location.href = '$url'";
echo "</script>";</code>
Copy after login
Copy after login

而下面代码服务器返回空白页面,没有执行我的命令,请问是怎么回事?php小白,照葫芦画瓢写的代码:

<code>echo "<script>";
echo "function()
{
   alert($error_msg);
   setTimeout(window.location.href = '$url',5);
}";                    
echo "</script>";
    </code>
Copy after login

setTimeout(func,5);
前面func是一个方法

<code>echo "<script>";
echo "function func()
{
   alert($error_msg);
   window.location.href = '$url';
}";
setTimeout(func,5);                    
echo "</script>";</code>
Copy after login

楼上仁兄正解

<code><?php $url = "http://www.baidu.com";
$error_msg = "error";
echo "<script>";
echo "function jump()
{
   alert('$error_msg');
   window.location.href = '$url';
}
setTimeout(jump, 3000);
";                    
echo "";</code>
Copy after login

你js部分只是定义了函数没有调用啊
