我想在iframe中发布一个表单，像这样生成：
我的JS在页面内加载一个iframe，向iframe添加一个表单并提交表格。我想要发生的是加载该请求结果的iframe。因此，我希望有效地发布表单并在iframe中呈现结果 ，而不触及父级（除了将iframe放在第一位显示外）。
我使用这个答案中的代码：
JavaScript post request like a form submit
但我无法让它不能重新加载父项。我发布表单，而不是iframe刷新，整个父级刷新。我不知道这是为什么，因为它发布的网址是不同的，至少会重定向到那里。
任何人都可以帮我解决这个问题吗？我只想在iframe中放置一个帖子，并且只在iframe中，基本上。编辑：经过一些更多的研究，显然表单没有被正确创建。我使用了document.createElement（form），然后是document.getElementById（my_iframe_id）。appendChild（form）来追加它，但它似乎没有正常工作。
解决方案正确，因为您正在当前文档中创建表单节点。
的document.getElementById（ my_iframe_id）contentWindow.document.createElement（ '形式'）。在iframe中创建它。
I would like to POST a form in an iframe, generated like so:
My JS loads an iframe inside the page, adds a form to the iframe and submits the form. What I would like to happen is the iframe to load the result of that request. So, I would effectively like to post a form and render the result inside the iframe, without touching the parent (apart from putting the iframe up for display in the first place).
I am using the code from this answer:
JavaScript post request like a form submit
but I can't get it to not reload the parent. I post the form, and instead of the iframe refreshing, the entire parent refreshes. I don't know why that is, since the url it's posting to is different and would at least redirect there.
Can anyone help me with this problem? I just want a post inside an iframe and only within the iframe, basically.
EDIT: After some more research, apparently the form is not being created properly. I'm using document.createElement("form") and then document.getElementById("my_iframe_id").appendChild(form) to append it, but it does not seem to be working correctly.
解决方案Correct, because you are creating the form node in the current document.
document.getElementById("my_iframe_id").contentWindow.document.createElement('form');to create it inside the iframe.
