javascript - ruby Watir : Clicking OK on JavaScript Alerts?

Question

似乎我试过的所有代码都没有任何影响。我的意图是关闭所有可能通过点击“确定”按钮出现的 JavaScript 提示。问题是，我的脚本对出现的提示没有影响。换句话说，它什么都不做。

这是我所拥有的:

fx = FireWatir::Firefox.start(somepage)
fx.startClicker("OK")
fx.button(:id, "OK").click
fx.button(:id, "CONFIRM").click

HTML:

<script type="text/javascript">
    alert("Alert!");
    window.confirm("Confirm?");
</script>

提示中的文本可以更改，我的意图是无论警报/确认提示中的内容如何，​​都单击“确定”。

PS:我正在运行 Ubuntu。

最好的方法是完全阻止弹出窗口的触发。

require 'watir'
b = Watir::Browser.start "http://somepagewithdialogs"
# don't return anything for alert
b.execute_script("window.alert = function() {}")

# return some string for prompt to simulate user entering it
b.execute_script("window.prompt = function() {return 'my name'}")

# return null for prompt to simulate clicking Cancel
b.execute_script("window.prompt = function() {return null}")

# return true for confirm to simulate clicking OK
b.execute_script("window.confirm = function() {return true}")

# return false for confirm to simulate clicking Cancel
b.execute_script("window.confirm = function() {return false}")

# interact with some element which would trigger the pop up
b.button(:id => "dialogTrigger").click
