java - Selenium Java：无法从日期选择器中选择日期

Question

我试图从自定义日期选择器中选择一个日期，但它不起作用。

HTML 与它的外观截图一起粘贴如下。

HTML：

<div id="ui-datepicker-div" class="ui-datepicker ui-widget ui-widget-content ui-helper-clearfix ui-corner-all ui-datepicker-multi ui-datepicker-multi-3" style="position: absolute; top: 546px; left: 331px; z-index: 1; display: block; width: 51em;">
    <div class="ui-datepicker-group ui-datepicker-group-first">

我曾尝试过

WebElement dateWidget = driver.findElement(By.className("ui-state-default"));
List columns=(List) dateWidget.findElements(By.tagName("ui-state-default"));
for (WebElement cell: columns){
      //Select 13th Date 
      if (cell.getText().equals("13")){
            cell.findElement(By.linkText("13")).click();
            break;
      }
}

甚至尝试等待命令以便找到定位器但没有成功。

WebDriverWait(driver,100).until(ExpectedConditions.elementToBeClickable(By.cssSelector

两者都不起作用，因为它无法识别元素可以帮助我解决这个问题。如果可能的话，我们甚至可以单击上一个和下一个，以便我们也可以单击一些以前的日期吗？

您确实使用错误By.tagName("ui-state-default")，ui-state-default是一个类而不是标签，您的代码在下面一无所获：

WebElement dateWidget = driver.findElement(By.className("ui-state-default"));
List columns=(List) dateWidget.findElements(By.tagName("ui-state-default"));

下面的代码在第一个月返回a文本13 ：

driver.findElement(By.xpath("//div[@id='ui-datepicker-div']//a[.='13']")).click();

如果日期选择器使用以下选项，您可以选择上个月findElements：

List<WebElement> dates = driver.findElements(By.xpath("//div[@id='ui-datepicker-div']//a[.='13']"));
dates.get(2).click();

您也可以使用data-month属性：

driver.findElement(By.xpath("//div[@id='ui-datepicker-div']//td[@data-month='3']/a[.='13']")).click();
