How to send parameter to Iframe with a HTTP POST request
提问by jRicca
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?
我必须使用 POST 方法将一些参数发送到 IFRAME。我在这里阅读了设置 <iframe> 的 HTTP 请求类型，这是不可能的。我正在考虑 Javascript 中的解决方案，但我无法实现它，因此我无法测试它是否是解决此问题的有效解决方案。我想问一下是否有人有同样的问题，是否可以解决，在积极的情况下如何解决？

How about using the target attribute of the form to point to iFrame?
如何使用表单的目标属性指向 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
只是举一个具体的工作例子
<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>
