Question

我正在使用selenium-java和chrome驱动程序从UL列表中选择元素。我正在尝试选择“ Sirsa”项目，但没有任何反应。 UL List结构类似于以下内容：

<div class="serachDept" id="names_department"><span class="departmentText">Mumbai</span>
    <ul class="serachDeptOptionList" style="overflow-y: scroll;">
        <li class="serachDeptOptionListElement"><span data-filter-value="Ratia"
                                                    class="srSearchOptionListElementText">Ratia</span></li>
        <li class="serachDeptOptionListElement"><span data-filter-value="Sirsa"
                                                      class="srSearchOptionListElementText">Sirsa</span></li>

        </li>
    </ul>
</div>

我使用Java代码选择了元素：

 WebElement namesList = Hooks.driver.findElement(By.xpath("//*[@id='names_department']//ul"));
    List<WebElement> options = namesList.findElements(By.tagName("li"));
    for (WebElement option : options) {
        option.findElement(By.tagName("Span")).click();  // throws exception
    }
    options.get(2).click();//throws exception

有人可以帮我解决这个问题吗？

Answer 1

解决方案是使用JavascriptExecutor

JavascriptExecutor executor = (JavascriptExecutor)driver;
executor.executeScript("arguments[0].click();", options.get(2));

Answer 2

尝试一下：

    List<WebElement> elements = 
    Hooks.driver.findElements(By.xpath("/*@id='names_department']//ul/li"));
    for (int i=0; i<elements.size(); i++) {
        if (elements.get(i).getTagName().equals("span") {
        elements.get(i).click()
        }       
    }
    elements.get(2).click();

Answer 3

您上面的代码看起来有问题。您需要打破循环：

WebElement namesList = Hooks.driver.findElement(By.xpath("//*[@id='names_department']//ul"));
List<WebElement> options = namesList.findElements(By.tagName("li"));
for (WebElement option : options) {
    option.findElement(By.tagName("Span")).click();
    break;
}
//options.get(2).click();//throws exception

或类似下面的内容。

WebElement namesList = Hooks.driver.findElement(By.xpath("//*[@id='names_department']//ul"));
List<WebElement> options = namesList.findElements(By.tagName("li"));
for (WebElement option : options) {
   if("Sirsa".equalsIgnoringCase(option.getText())){
      option.click(); 
      //option.findElement(By.tagName("Span")).click();
      break;
   }
 }

以上代码至少不会引发命令超时异常。而且，如果您发现点击没有生效，则可以使用javascript来触发点击。

为处理此类情况，众所周知的开源框架QAF提供了一种称为custom component的功能。使用它，您可以为Webelement定制实现。
