Question

我正在使用Firefox + searchbastard插件在购物搜索引擎上进行多重搜索。这些页面是一个框架的一部分。这对我迄今为止尝试的所有网站都很好，除了shopmania.com。

如果我使用noscript来禁止shopmania域名中的脚本，那么一切都会保留，但网站元素的一部分会变得没有响应。我知道Firefox中有一个选项可以强制在新窗口中打开的链接在新选项卡中打开。是否有类似的东西阻止网站突然出现？也许是一个阻止这些请求的Firefox插件？

或者至少有人可以告诉我是什么原因导致只有这个网站这样做？

编辑：我可以使用什么工具暂停firefox或javascript和c ++中的单步代码？我尝试了一个javascript调试器和firebug。他们没有帮助，但我可能没有正确使用它们。

EDIT2：我试过这个greasemonkey脚本：https://userscripts.org/scripts/show/92424。它不起作用所以我想这不是因为'目标'属性

Answer 1

这是错误的。我猜你正在使用插件来捕获和覆盖某些网站给你的输出。我很确定这违反了他们的ToS，一般来说这不是一件好事。

JavaScript不是为了允许这种插手而设计的。它充其量不完整。

如果您想使用网站上的数据，以某种方式聚合或显示，请使用其公共API。如果他们没有公共API，他们可能不希望您以这种方式使用他们的服务。

解决方案：我从Stop execution of Javascript function (client side) or tweak it获取了脚本并对其进行了修改以搜索其中包含的标记top.location = location，然后使用if（top！= self）{top附加了一个新脚本.location = location;}行评论。作为一个js总新手，我不知道它是否是最优雅的选择，但它可以推动它。特别感谢Tim Fountain 我将保持开放，以防其他人为我和他人的教育提出更好的解决方案。再次感谢您的帮助以下是代码：
