How to send parameter to Iframe with a HTTP POST r

问题:

I have to send some parameter to an IFRAME with POST method. I have read here Setting the HTTP request type of an <iframe> that it isn't possible. I'm thinking a solution in Javascript but I can't implement it so I can't test if it is a valid solution for this issue. I want to ask if someone has the same problem and if it is possible to solve and in positive case how to?

回答1:

<form ... target="hidden_iframe">
...
</form>

<iframe name="hidden_iframe" ...></iframe>

回答2:

How about using the target attribute of the form to point to iFrame?

 <form target="myIframe" action="http://localhost/post.php" method="post">
    <input type="hidden" value="someval" />
    <input type="submit">
</form>

<iFrame src="" name="myIframe"></iFrame>

Just to give a concrete working example

<form id="loginForm" target="myFrame"  action="https://localhost/j_spring_security_check" method="POST">
 <input type="text" name="j_username" value="login" />
 <input type="text" name="j_password" value="password" />
 <input type="submit">
</form>

<iframe name="myFrame" src="#">
   Your browser does not support inline frames.
</iframe>

// Hide the form and do the submit 
<script>
 $(document).ready(function(){
 var loginform= document.getElementById("loginForm");
 loginform.style.display = "none";
 loginform.submit();
});
</script>
