phantomjs通过watir-webdriver,不处理javascript警报

Question

我正在尝试在网页上自动执行某些任务,其中一部分包括单击一个链接,该链接将显示一个javascript警报,您必须按"确定".麻烦的是,当它到达那一点时,它失败并出现以下错误

在线搜索,似乎麻烦可能与ghostdriver有关,也许phantomjs无法做到,但这个概念对我来说似乎有点奇怪(毕竟它被称为幻影*js*,并且警报是非常基本的javascript ),但也许我看错了.

使用chrome运行脚本,它可以完美运行.

有一个已知的问题,PhantomJS无法正确处理JavaScript.一种解决方法是通过运行以下命令禁用警报框:

@browser.execute_script("window.confirm = function(){return true;}");

基本上,您要遵循的步骤是:

1. 转到该页面
2. 运行上面的命令
3. 点击"删除"(或触发警报框的任何内容)
4. 它会自动为您点击"确定".
