Selenium WebDriver - Java - 单击按钮 [英] Selenium WebDriver - Java - Click a button
问题描述
我正在尝试点击一些按钮，我正在使用twitch上的Follow按钮作为示例。
I'm trying to click some buttons and I'm using the Follow button on twitch as an example.
我使用Selenium IDE尝试获取按钮的xpath。我得到的xpath是： // span [@ id ='ember637'] / a / span
I used the Selenium IDE to try to get the xpath for the button. What I got as xpath was: //span[@id='ember637']/a/span
如果我去FireFox并为按钮复制唯一选择器，我会得到： .js-follow> span：nth-child（1）
If I go to FireFox and copy unique selector for the button I get: .js-follow > span:nth-child(1)
我在java程序中尝试了两种方法但它们都不起作用。当我使用 // span [.. xpath时，我收到以下错误：
I have tried both in the java program and they don't work. When I use the //span[.. xpath I get the following error:
"Unable to locate a node using //span[@id='ember637']/a/span"
编辑：
我想点击按钮的网站示例（关注按钮）：
http://www.twitch.tv/mradder89/profile/
Example of a site with a button I want to click(The Follow button): http://www.twitch.tv/mradder89/profile/
我使用的Selenium jar文件是selenium-server-standalone-2.35.0.jar
The Selenium jar file I am using is "selenium-server-standalone-2.35.0.jar"
我得到的错误是
"Exception in thread "main" org.openqa.selenium.NoSuchElementException: Unable to locate a node using //span[@id='ember637']/a/span"
编辑2：
我下载了PhantomJSDriver exe文件（phantomjs.exe）并试用了它。它不起作用...
我没有像以前那样收到错误消息（无法找到节点......错误）。
I downloaded the PhantomJSDriver exe file(phantomjs.exe) and was trying it out. It doesn't work... I do not get a error message like before(the 'Unable to locate a node...' error).

推荐答案
使用PhantomJSDriver，尝试不同的定位器。发布例外（如果有），否则发布最新信息，例如位置，文本等。
With PhantomJSDriver, try different locators. Post exceptions if there are any, otherwise post the elemenst's info, e.g. location, text, etc.
driver.findElement(By.xpath("//*[contains(@class, 'profile-actions')]//span[text()='Follow']")).click();
driver.findElement(By.cssSelector(".profile-actions .primary_button > span")).click();
