无需经过execScript。你可以写下一个parentWindow.history.forward（1）;

无论如何，我不确定这应该是什么。此代码只是以编程方式单击"前进"按钮。除非用户之前已单击"返回"，否则"前进"按钮将被禁用，此代码不会执行任何操作。即使它有所作为，为什么你会期望它禁用后退按钮？

No need to go through execScript. You could just write

parentWindow.history.forward(1);

In any case, I'm not sure what this is supposed to achieve. This code
just programmatically clicks the Forward button. Unless the user has
previously clicked Back, the Forward button is disabled and this code
does nothing. Even when it does something, why do you expect it to
disable the Back button?
