即使脚本在_blank窗口中运行，我们也可以在原始窗口上触发脚本吗
问题描述：
这是设置:
在Paypal上单击按钮(在_blank中打开)，我的焦点窗口变为Paypal，可以在原始窗口中运行脚本.
On Paypal click button (openned in _blank) My focus window becomes Paypal, is it possible to run a script in original window.
现在我的脚本是((如果目标位于原始页面的iframe中，效果很好)，但是Paypal不允许，这就是我遇到的问题的原因)
Right now my script is (and it works well if target is within iframe of original page - but Paypal does do not allow it, that's why I have the issue):
$click = '<script type="text/javascript">window.top.parent.parent.submitsubmit();</script>';
echo $click;
只是想知道我想做的事是否现实，
Just wondering if what I want to do is realistic,
预先感谢

可以对已在_blank中打开的窗口进行脚本编写.但是，如果打开的URL具有不同的(子)域，则无法访问内容.
Scripting towards a window that has been opened in a _blank is possible. However accessing the contents is not possible when the opened url is of a different (sub)domain.
