Selenium 从日期选择器中选择第一个和最后一个活动日期答案

【问题标题】：Selenium pick 1st and last active date from date pickerSelenium 从日期选择器中选择第一个和最后一个活动日期
【发布时间】：2021-06-13 06:27:02
【问题描述】：

我正在尝试查找第一个也是最后一个活动日期。在下图中，您可以看到第一个活跃日是 6 月 2 日。最后一个活跃日是 2022 年 6 月 1 日

我想获取第一个活动日期，即 June02,2021 和最后一个活动日期

我有这个代码打印 2021-5-3，它没有打印 2021-6-3

List<WebElement> columns = driver.findElements(By.xpath("//td[not(@class=' ui-datepicker-other-month ui-datepicker-unselectable ui-state-disabled') and not(@class=' ui-datepicker-week-end ui-datepicker-other-month ui-datepicker-unselectable ui-state-disabled') and not(@class=' ui-datepicker-unselectable ui-state-disabled ')]"));
    ArrayList<String> yearList= new ArrayList<>();
    ArrayList<String> monthList= new ArrayList<>();
    ArrayList<String> dateList= new ArrayList<>();
    for(int i=1;i<columns.size();i++){
        yearList.add(driver.findElement(By.xpath("//td[@class=\" \"]")).getAttribute("data-year"));
        monthList.add(driver.findElement(By.xpath("//td[@class=\" \"]")).getAttribute("data-month"));
        dateList.add(driver.findElements(By.xpath("//td[@data-handler=\"selectDay\"]/..//a[@href]")).get(i).getText());
        /*System.out.println(driver.findElements(By.xpath("//td[@data-handler=\"selectDay\"]/..//a[@href]")).get(i).getText() + "-"+
                driver.findElement(By.xpath("//td[@class=\" \"]")).getAttribute("data-month") + "-"
        + driver.findElement(By.xpath("//td[@class=\" \"]")).getAttribute("data-year"));*/

    }
    System.out.println("1st Active Date " + yearList.get(0) +"-"+monthList.get(0)+"-"+dateList.get(0));

我还尝试单击“下一步”> 符号，直到获得最后一个活动日期。我尝试了下面的代码，但由于找不到元素异常而失败

 if ((driver.findElement(By.xpath("//a[@class='ui-datepicker-next ui-corner-all' and @title='Next']")).isDisplayed())) {
        driver.findElement(By.xpath("//a[@title='Next']")).click();
        while(!(driver.findElement(By.xpath("//a[@class='ui-datepicker-next ui-corner-all ui-state-disabled' and @title='Next']")).isDisplayed()) ){
            driver.findElement(By.xpath("//a[@title='Next']")).click();
      }
        /*if ((driver.findElement(By.xpath("//a[@class='ui-datepicker-next ui-corner-all ui-state-disabled' and @title='Next']")).isDisplayed())) {
            break;
        }*/
    }

<a class="ui-datepicker-next ui-corner-all" data-handler="next" data-event="click" title="Next"><span class="ui-icon ui-icon-circle-triangle-e">Next</span></a>

提前感谢您的时间和帮助。

【问题讨论】：

你想找到当前月份的最后一个活动日期，还是让 selenium 继续点击下一个直到没有活动日期？
我们需要查看您的完整 HTML 来解决这个问题。请不要张贴图片；它们很难阅读，无法复制，而且无论如何都没有显示所有必要的信息。
@prakasht 继续点击直到我得到 2022 年 7 月 1 日谢谢。
@C.Peck 长代码我试着在底部放一些 HTML 代码。谢谢
HTML 没有帮助。你有这个网站的链接吗？

标签： java selenium

【解决方案1】：

可以借助 xpath 中的last() 方法来完成。你需要遵循以下逻辑：

查找与所有活动日期匹配的 xpath。
String activeDatesXpath = "find_this_xpath"; // You can fill this xpath as you have the html.
首先使用：
WebElement firstDate = driver.findElement(By.xpath(activeDatesXpath + "[0]")) 获取第一个活动日期
现在要查找最后一个活动日期，循环运行直到您点击NoSuchElementException，然后在每个页面上保存最后一个活动日期

WebElement lastDate = driver.findElement(By.xpath(activeDatesXpath + "[last()]");
while(true) {
       try {
           // Click Next
           driver.findElement(By.xpath("//a[@title='Next']")).click();
           // Update the lastDate element
           lastDate = driver.findElement(By.xpath(activeDatesXpath + "[last()]");
       } catch (NoSuchElementException e) {
           break;
       }
}

您还应该设置最大页数限制，这样如果活动日期没有结束，您的代码就不会陷入无限循环。
