Question

我有一个类似这样的页面：

<input type="button" onclick="confirm('confirm popup');" value="click" />

当我转到该页面并点击链接时：

require "watir-webdriver"
browser = Watir::Browser.new
browser.goto "page.html"
browser.button.click

确认弹出窗口出现。我可以解雇它：

require "watir-webdriver/extensions/alerts"
browser.confirm(true) {browser.button(:value => 'Confirm').click}

但我收到此错误消息：

我将向您推荐这个答案https://stackoverflow.com/a/8172888/409820，其中我解释了使用browser.confirm这样的方法。其示例有点令人困惑，因为它们直接来自测试，并且如果您不理解测试页上有多个按钮的上下文，并且导致确认对话框的那个具有值'confirm'然后由该方法包装的'inner'命令没有多大意义。

confirm方法之后的循环（或块）中的命令是导致弹出窗口发生的命令。

因此，如何使用这些方法的更好的例子就像是

alert_message_text = browser.confirm(true) do
  #watir code that causes confirm popup goes here
end

或

alert_message_text = browser.confirm(true) {#code that causes confirm popup}

换句话说，使用.confirm(response) {block}的方式就像告诉watir一样“好吧我在块中给你的命令会导致出现一个确认对话框，当它出现时我想让你拿走由response“

指定的操作

所以你出错的地方是块里面的命令，你需要在块内移动'browser.button.click'或类似的东西。您的代码最终会看起来像这样

require "watir-webdriver"
require "watir-webdriver/extensions/alerts"

browser = Watir::Browser.new
browser.goto "page.html"
browser.confirm(true) {browser.button(:value => 'click').click}

我将您的点击操作更改为更具体，根据您提供的HTML中的值属性识别按钮。如果您确定它始终是页面上的第一个按钮，您可以将最后一行更改为

browser.confirm(true) {browser.button.click}

解雇确认弹出窗口后出现模态对话框（Selenium :: WebDriver :: Error :: UnhandledAlertError）
