Question

selenium中，用Xpath的方法选取一个href

我要选择这个签到/签退。我的代码如下：
selenium.selectFrame("//frameset[@id=''framedown']");
selenium.click("//div[@id='qiandao']/table/tbody/tr[1]/td[1]/a");
报错：

Answer 1

selectFrame(locator)
Arguments: locator - an element locator identifying a frame or iframe
注意参数必须是frame or iframe 的locator, 你用的是frameset的.

所以试试将 selenium.selectFrame("//frameset[@id=''framedown']");
改为: selenium.selectFrame("name=menu");
或者 selenium.selectFrame("//frameset[@id=''framedown']//frame");
