Meta Refresh with a frame target

问题

I have a very basic frame layout: index.html

<frameset rows="80,*" frameborder="1" border="5" framespacing="0">
    <frame name="topNav" src="top_nav.html">
    <frameset cols="220,*" frameborder="1" border="5" framespacing="0">
    <frame name="menu" src="menu_1.php" marginheight="0" marginwidth="0" scrolling="auto" noresize>
    <frame name="content" src="content.php" marginheight="0" marginwidth="0" scrolling="auto" noresize> 
</frameset>
</frameset>

And a simple login script which checks if the username and password match the database and so on

Now what i want it to do is if the information is correct, is to auto redirect the menu bar, but all i can do is redirect the content section

// check to see if they match!
  if ($username==$dbusername&&$password==$dbpassoword)
  {
      $_SESSION['username']=$username;
      echo '<meta http-equiv="REFRESH" content="2 ; url=servers.php" target="menu">';
  }
  else 
      echo "<center>Incorrect Information!</center>" ;

Now i can easily do it if i get the user to click on an <a href> tag

E.G. <a href="servers.php" target="menu">click me</a>

So i thought i could simply put the target="menu" in my meta tags, but all it does is redirect the content page.

So my question is, am i doing something wrong, or is there a simpler way to do this?

回答1:

I believe you can't do it with headers. You could output regular javascript along your content. Something like this:

<script>
    parent.menu.location.href = "/some-url";
</script>

回答2:

Give you frame (menu) an id: Then change the code like this:

Change

echo '<meta http-equiv="REFRESH" content="2 ; url=servers.php" target="menu">';

echo '<script>var iframe = document.getElementById("youriframe");iframe.src="servers.php";</script>';
