推荐答案

最好的办法是打开一个弹出窗口，并加载测试在弹出。

Best way would be to open a pop up window and load the test in that pop up.

使用的window.open（），然后你可以提供额外的参数。 这里提供

Use window.open() and then you can provide additional parameters. as provided here

这样，用户将不能够在该弹出打开新的标签页。另外你可以做的就是密切从中新的弹出窗口已经打开的标签

That way user will not able to open new tab on that pop up. Also what you can do is close the tab from which new pop up has been opened
