How to POST in window.open()
提问by Victor
When we do a window.open(), is there an option to specify method = POST? Since by default, it is GET?
当我们执行 a 时window.open()，是否可以指定选项method = POST？因为默认情况下，它是GET?
What I want is this. The parent window has some form parameters (many in number) and they should be sent to the server on window.open(). It is not a good idea to append all of them in the GETurl using query string.
我想要的是这个。父窗口有一些表单参数（数量很多），它们应该在window.open(). GET使用查询字符串将所有这些附加到url 中并不是一个好主意。

You could use window.open()to open an empty window, with a name. Then you could use a <form>with a "target" attribute referring to that new window's name, and post it.
您可以使用window.open()打开一个带有名称的空窗口。然后，您可以使用<form>带有“目标”属性的 a 来引用该新窗口的名称，然后发布它。
editOK here's the idea. You have a form on the page, and it can be hidden:
编辑好这里的想法。您在页面上有一个表单，它可以隐藏：
<form id='theForm' method='post' action='/your/action' target='TheNewWindow'>
<input type='hidden' name='param_1' value='whatever'>
</form>
Then you get the results into your window like this:
然后您将结果放入您的窗口，如下所示：
window.open('about:blank', 'TheNewWindow');
document.getElementById('theForm').submit();
Make sure that the window name you use is a valid identifier (like a JavaScript variable name), or IE will get upset.
确保您使用的窗口名称是有效的标识符（如 JavaScript 变量名称），否则 IE 会感到不安。
