无法集中网页元素发送密钥

Question

我有一组测试，我需要登录然后执行搜索。 我的应用程序是一个角JS，我正在起诉量角器。 事实上，我的测试在那里工作的罚款，直到我收到我的申请，新的工具包，我所有的测试都在这一点上失败：

element(by.id('mainGlobalSearchBtn')).sendKeys('a'); 

这里是我的控制台输出：

1) change number of items displayed by page should display 20 items per page

我会补充一点，量角器不能点击/在我的任何网页元素的输入文字在登录后

这里是我的搜索表单HTML：

<form class="ng-pristine ng-valid" id="mainSearchGroup" name="mainSearchGroup"> 
    <div id="mainSearch"> 
     <input class="ng-pristine ng-valid" id="mainGlobalSearch" name= 
    "mainGlobalSearch" placeholder="Schedule workflows, name..." type= 
    "text"> 

     <div id="mainSearchIn" style="background-image: url(" title= 
    "Filter by..."> 
     <div class="word-ellipsis ng-binding" id="mainSearchInText"> 
      All 
     </div> 

     <div id="mainSearchInRightGrayBorder"></div> 

     <div id="mainSearchInBox" style=""></div> 
    </div> 

    <div class="ng-binding" id="mainGlobalSearchBtn"> 
     <div class="clear"></div> 
     </div> 
    </div> 
</form> 

Answer 1

这量角器错误或更精确角1.2.X及以上和量角器之间的兼容性错误=>同步失败 散步周围将在每个功能之前添加这一行：

ptor.ignoreSynchronization = true; 

并添加睡眠（'5000'）与Angular JS手动同步。

Answer 2

您可以尝试用<input type="text">或<input type="button">替换“#mainGlobalSearchBtn”div，该打算用于接收.sendKeys（）命令。

Answer 3

如果它对下一个人有帮助，我必须在发送密钥之前在域内使用.click（）。

Answer 4

显然有一些问题when using protractor, angular, and chrome.

尝试使用Firefox作为浏览器。编辑你的量角器配置文件是这样的：

exports.config = { 
    seleniumAddress: 'http://localhost:4444/wd/hub', 
    specs: ['spec/spec.js'], 
    capabilities: { 
    'browserName': 'firefox' 
    } 
} 

这样做后，我不再经历这个问题。

Answer 5

我不得不使用这个巨大的成功：

Actions actions = new Actions(driver); 
actions.moveToElement(element); 
actions.click(); 
actions.sendKeys("Some Name"); 
actions.build().perform(); 

这里找到：http://grokbase.com/t/gg/selenium-users/142jj2483b/chromedriver-error-cannot-focus-element

该解决方案还支持C＃，因为相同的类和方法都存在的API中。

Answer 6

它在量角器中为我工作：

browser.driver.actions（）。 mouseDown（元素）。 click（）。 sendKeys（“某些文本”）。 perform（）;

谢谢。

Answer 7

有点迟到了，但那些寻找一个解决这个问题，同时使用的python硒可以使用下面的代码：

actions = webdriver.ActionChains(driver) 
actions.move_to_element(my_div) 
actions.click() 
actions.send_keys(Keys.SPACE) # Replace with whichever keys you want. 
actions.perform() 

哪里my_div是您之前选择的元素，也许用这样的代码：

my_div = item.find_element_by_css_selector("div.foobar")
