问题描述

我正在尝试从引导下拉列表中列出所有元素，然后选择某个值.但是，它返回 0 值.任何建议将不胜感激.

I am trying to list all elements from the bootstrap dropdown and then select a certain value. However, it returns 0 values. Any suggestions will be greatly appreciated.

driver.findElement(By.id("imgSelectButton")).click();
Thread.sleep(3000);
List<WebElement> list = driver.findElements(By.xpath("//ul/li[@class='logoSelectOpt']//li"));
System.out.println(list.size());
for(int i=0; i<list.size(); i++){
    System.out.println(list.get(i).getText());
    if (list.get(i).getText().contains("History")){
        list.get(i).click();
        break;
    }
}

DOM:

<div class="logoSelect" style="z-index:1; top:878px;">==$0
 <ul>
  <li class="logoSelectOpt" id="12" onmouseover="jQuery(QWE01Title.activate(this);" onmouseout="jQuery(QWE01Title.deactivate(this);" onmousedown="jQuery(QWE01Title.selectItem(this);" logoColor="#FFF">Facts</li>==0
  <li class="logoSelectOpt" id="12" onmouseover="jQuery(QWE01Title.activate(this);" onmouseout="jQuery(QWE01Title.deactivate(this);" onmousedown="jQuery(QWE01Title.selectItem(this);" logoColor="#FFF">History</li>==0
  <li class="logoSelectOpt" id="12" onmouseover="jQuery(QWE01Title.activate(this);" onmouseout="jQuery(QWE01Title.deactivate(this);" onmousedown="jQuery(QWE01Title.selectItem(this);" logoColor="#FFF">Opinions</li>==0
  <li class="logoSelectOpt" id="12" onmouseover="jQuery(QWE01Title.activate(this);" onmouseout="jQuery(QWE01Title.deactivate(this);" onmousedown="jQuery(QWE01Title.selectItem(this);" logoColor="#FFF">Questions</li>==0
 </ul>
</div>

推荐答案

元素是 jQuery 启用元素所以找到您必须为 visibilityOfAllElementsLocatedBy() 诱导 WebDriverWait 的元素，您可以使用以下任一 定位器策略:

The elements are jQuery enabled element so to locate the elements you have to induce WebDriverWait for the visibilityOfAllElementsLocatedBy() and you can use either of the following Locator Strategies:

• 使用cssSelector:

driver.findElement(By.id("imgSelectButton")).click();
List<WebElement> list = new WebDriverWait(driver, 20).until(ExpectedConditions.visibilityOfAllElementsLocatedBy(By.cssSelector("div.logoSelect > ul li.logoSelectOpt")));
System.out.println(list.size());
for(int i=0; i<list.size(); i++){
    System.out.println(list.get(i).getText());
    if (list.get(i).getText().contains("History")){
        list.get(i).click();
        break;
    }
}

driver.findElement(By.id("imgSelectButton")).click();
List<WebElement> list = new WebDriverWait(driver, 20).until(ExpectedConditions.visibilityOfAllElementsLocatedBy(By.xpath("//div[@class='logoSelect']/ul//li[@class='logoSelectOpt']")));
System.out.println(list.size());
for(int i=0; i<list.size(); i++){
    System.out.println(list.get(i).getText());
    if (list.get(i).getText().contains("History")){
        list.get(i).click();
        break;
    }
}
