How to call parent's parent javascript function from child window.
如何从子窗口调用父级的父 JavaScript 函数。
Example- Parent 1 has javascript function abc() Now how to call Parent1 Javascript function in Child window from Parent 2 which is initially trigged from Parent 1 Window. I tried window.parent.parent. Still no luck.
示例 - 父 1 具有 javascript 函数 abc() 现在如何从最初从父 1 窗口触发的父 2 中在子窗口中调用 Parent1 Javascript 函数。我试过window.parent.parent。仍然没有运气。
Thanks in advance

Not sure what you mean with a child window. But I guess window.openermight be what you are looking for.
不确定您对子窗口的意思。但我想window.opener可能是你正在寻找的。
// Call abc in the window that opened the current window
window.opener.abc();

Haven't tried it, but since window.openeris a reference to the window that opened the current window, then I guess you should be able to call the openerproperty on that reference, to get a reference to the its parent as well:
还没有尝试过，但由于window.opener是对打开当前窗口的窗口的引用，那么我想您应该能够调用该opener引用上的属性，以获取对其父级的引用：
window.opener.opener.abc();
If you want to reach the topmost window (the root window, or what you would call it), then you can use window.topinstead:
如果你想到达最顶层的窗口（根窗口，或者你称之为的窗口），那么你可以使用window.top：
window.top.abc();
