推荐答案

window.parent 指的是一帧（或iframe的）母公司：

window.parent refers to a frame's (or iframe's) parent:

<frameset cols="25%,75%">
   <frame src="frame_a.aspx" name="frameA" />
   <frame src="frame_b.aspx" name="frameB" />
</frameset>

在上面的例子中，如果 window.parent 在frame_a.aspx被执行，它会指向包含的＆lt窗口;框架＆GT;元素。

In the above example, if window.parent were executed in frame_a.aspx, it would refer to the window containing the <frameset> element.

目标指的是一帧（按名称）或标准的目标：

Target refers to either a frame (by name) or a standard target:

• _blank - 新窗口


• _parent - 当前帧的父级


• _top - 最顶部的框架（整个浏览器窗口/标签）

• _blank - New window
• _parent - Current frame's parent
• _top - Top-most frame (entire browser window/tab)

_top 和 _parent 只是指不同的东西，如果你的框架是多个级别深度（例如，如果frame_a.htm包含在另一个框架或iframe）

_top and _parent only refer to different things if your frames are more than one level deep (eg. if frame_a.htm contained another frameset or iframe)

'window.parent。 +目标+'.location正在改变帧的URL，包含在当前帧的父内，用可变psented名重$ P $ 目标。 （我假设 taget 简直就是一个错字）。

'window.parent.' + target + '.location' is changing the URL of a frame, contained within the current frame's parent, with the name represented by the variable target. (I have assumed taget is simply a typo).

在我上面的例子中，如果frame_a.aspx与目标变量frameB执行你的例子code，它会改变该帧的东西的网址其他（不影响frameA）。

In my above example, if frame_a.aspx executed your example code with the target variable "frameB", it would change the url of that frame to something else (without affecting frameA).

虽然你没有提到它，它可能使用的是 window.open ，并试图打开它的窗口中更改位置。在这种情况下，你正在寻找 window.opener 。

Although you haven't mentioned it, it's possible you are using window.open and are trying to change the location on the window that opened it. In that case, you are looking for window.opener.
