无法关注web元素发送密钥

标签： javascript angularjs protractor

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Angular JS，我正在起诉量角器。 事实上，我的测试工作正常，直到我收到我的应用程序的新工具包并且我的所有测试都失败了：

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

这是我的控制台输出：

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

我想补充一点，量角器在登录后无法在我的任何网页元素中点击/输入文字。

这是我的搜索表单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>

我使用它取得了很大的成功：

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

在此处找到：http://grokbase.com/t/gg/selenium-users/142jj2483b/chromedriver-error-cannot-focus-element

此解决方案也适用于C＃，因为该API中存在相同的类和方法。

答案 1 :(得分：6)

如果它对下一个人有帮助，我必须在发送密钥之前在字段内单击.click（）。

答案 2 :(得分：4)

派对有点晚了，但是那些在python下使用selenium时寻找解决这个问题的人可以使用以下代码：

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()

my_div是您之前选择的元素，可能使用以下代码：

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

答案 3 :(得分：3)

在Protractor中它对我有用：

browser.driver.actions（）。             鼠标按下（元素）。             点击（）。             sendKeys（＆＃34; Some Text＆＃34;）。             执行（）;

感谢。

答案 4 :(得分：2)

这是一个Protractor错误，或者更准确地说是Angular 1.2.X及以上版本与protractor =＆gt;之间的兼容性错误同步失败 四处走动将在每个函数之前添加此行：

ptor.ignoreSynchronization = true;

添加sleep（'5000'）以与Angular JS手动同步。

答案 5 :(得分：2)

显然存在一些问题when using protractor, angular, and chrome.

尝试使用firefox作为浏览器。像这样编辑你的量角器配置文件：

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

这样做之后，我不再遇到这个问题了。

答案 6 :(得分：0)

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