我试图告诉我的watir脚本等待ajax注册登录框打开.我正在使用watir-webdriver,并在Chrome中进行测试.如下面(简化的)脚本所述,我无法让wait_until工作.
require "rubygems"
require "watir-webdriver"
b = Watir::Browser.new(:chrome)
site = "www.example.com"
b.goto site
puts "Click on Sign In button"
b.link(:id,'btnLogin').click
puts "Waiting for the username/password dialog to show up"
# Below line does *not* work
# Throws this error: "uninitialized constant Watir::Waiter (NameError)"
Watir::Waiter::wait_until { b.text_field(:id,'username').exists? }
# Below line does *not* work
# Throws this error: "undefined method `wait_until' for main:Object (NoMethodError)"
wait_until { b.text_field(:id,'username').exists? }
# Below line *does* work,but I don't want to use it.
sleep 1 until b.text_field(:id,'username').exists?
Watir ::服务员是仅IE类吗？或者我做错了什么,睡眠1等待方法工作正常.我是Ruby和watir的新手,我字面上只是昨天拿起来,所以我一半期望这是我的无礼的结果.
如果是相关的,我正在使用mac(OSX v.10.6.5).
解决方法
先做这个：
require "watir-webdriver/wait"
然后尝试这些：
1
Watir::Wait.until { ... }
2
browser.text_field(:id => 'username').when_present.set("name")
3
browser.text_field(:id => 'username').wait_until_present
请注意,这里的“present”表示“元素既存在又可见”.
