how can I get a reference to the newly opened window using the window name ('somewindowname') using jquery?
如何使用 jquery 使用窗口名称（'somewindowname'）获得对新打开的窗口的引用？
Perhaps something in the form of $('somewindowname') or something....
也许是 $('somewindowname') 形式的东西……

you can set the window as a variable like so
您可以像这样将窗口设置为变量
var foo;
foo = window.open(url, 'somewindowname');
you can then
然后你可以
use
利用
foo.close();
to close the window for instance. Note that this is a javascript variable not a jquery variable.
例如关闭窗口。请注意，这是一个 javascript 变量而不是 jquery 变量。

It has nothing to do with JQuery.
它与JQuery.
After opening the window for the first time, you can get a reference to it by using window.openfunction again and assigning the returned value to a variable:
第一次打开窗口后，可以通过window.open再次使用函数并将返回值赋给变量来获取对它的引用：
var existingWindow = window.open(url, "somewindowname");

There is some undocumented behavior that lets you get a reference to a window by name. I've mentioned it in this answer How to tell if a window exists in Javascript?
有一些未记录的行为可让您通过名称获取对窗口的引用。我在这个答案中提到过如何判断 Javascript 中是否存在窗口？
// Opened a window without storing a handle, but gave it a name
window.open('/some/url', 'xxx');
// Now I need to get a reference to that window
// Calling open without setting a url gets you
// a reference and doesn't reload the window
var win = window.open('', 'xxx')
Here's an example
这是一个例子
