selenium 等待ajax,WebRat Selenium WebDriver：等待ajax完成

我们最终在selenium上编写了一个层,通过在可选循环中包装调用来处理这种情况.所以,当你这样做时：

@browser.click "#my_button_id"

它会做类似于AutomatedTester建议的内容：

class Browser

def click(locator)

wait_for_element(locator,:timeout => PAGE_EVENT_TIMEOUT)

@selenium.click(locator)

end

def wait_for_element(locator,options)

timeout = options[:timeout] || PAGE_LOAD_TIMEOUT

selenium_locator = locator.clone

expression = <

var element;

try {

element = selenium.browserbot.findElement('#{selenium_locator}');

} catch(e) {

element = null;

};

element != null;

EOF

begin

selenium.wait_for_condition(expression,timeout)

rescue ::Selenium::SeleniumException

raise "Couldn't find element with locator '#{locator}' on the page: #{$!}.\nThe locator passed to selenium was '#{selenium_locator}'"

end

end

end

包装器也做了其他的事情,比如允许通过按钮/输入标签等进行搜索(因此包装器不仅存在时间问题,这只是我们放在那里的东西之一.)
