Submit a form in the background
提问by Alex Churchill
How can I submit a form to a third-party website without it causing the page to reload (i.e. in the background)?
如何在不导致页面重新加载（即在后台）的情况下向第三方网站提交表单？
For some background, I'm trying to programmatically log a user into their google account in the background.
对于某些背景，我试图在后台以编程方式将用户登录到他们的谷歌帐户。
I can programmatically log them in using the following:
我可以使用以下方法以编程方式登录它们：
var div = document.createElement("div");
div.innerHTML = FORM_HTML;
var form = div.getElementsByTagName("form")[0];
form.action = "https://www.google.com/accounts/ServiceLoginAuth";
form.GALX.value = FORM_GALX; // dynamically obtained using AJAX
form.Email.value = USER_EMAIL;
form.Passwd.value = USER_PASSWORD;
form.submit();
This logs me in and opens up my Google dashboard. How can I prevent form.actionfrom redirecting me?
这让我登录并打开我的 Google 仪表板。如何防止form.action重定向我？
Please note that this div is never actually added to a document, which is preferable but not required.
请注意，此 div 从未实际添加到文档中，这是可取的，但不是必需的。

you can set the target to submit the form to an IFRAME
like that
您可以设置目标以将表单提交到 IFRAME
这样的
<form target="transFrame" method="POST" action="http://...." ></form>
<iframe style="" name="transFrame" id="transFrame"></iframe>
