ruby - phantomjs 通过 watir-webdriver，不处理 javascript 警报

Question

我正在尝试自动执行网页上的某些任务，其中一部分包括单击一个链接，该链接将显示一个 javascript 警报，您必须在其中按“确定”。麻烦的是，当它到达那个点时，它会失败并出现以下错误

网上查了一下，好像是related to ghostdriver的问题也许 phantomjs 做不到，但这个概念对我来说有点奇怪(它被称为 phantom*js*，毕竟，警报是非常基本的 javascript)，但也许我'我看错了。

用 chrome 运行脚本，它完美运行。

Answer 1

存在一个已知问题，即 PhantomJS 无法正确处理 JavaScript。一种解决方法是通过运行禁用警告框:

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

基本上，您要遵循的步骤是:

1. 转到页面
2. 运行上面的命令
3. 点击“删除”(或触发警告框的任何内容)
4. 它会自动为您点击“确定”。
