Question

更新 - 我已添加以下整个HTML代码，以便更轻松地了解该问题。我尝试过使用xpath 的 findElement（By.xpath（ “.// DIV [@ ID = 'ContainerCell'] /跨度/ [@ ID = '开始日期'] /输入[@ ID = 'StartDate_txtInput']”））。gettext的（）

我仍然收到错误： 给定的选择器.//div [：id ='CONTinerCell'] / span / [@ id ='StartDate'] / input [@id ='StartDate_txtInput']无效或不会产生WebElement。发生以下错误： InvalidSelectorError：由于以下错误，无法找到带有xpath表达式的元素.//div[@id='ContainerCell']/span/[@id='StartDate']/input[@id='StartDate_txtInput'] SyntaxError：表达式不是合法表达式。

使用Selenium Webdriver我需要检索只读字段的值。此字段包含我需要与另一个日期进行比较的日期。我已经尝试了所有方法（通过id / class name / xpath等查找元素）它总是返回未找到的元素。我怀疑这是因为输入文件位于一个跨越div的内部，但是对java来说是新手，我无法进入这个领域。

我正在寻找的价值是<input id="StartDate_txtInput">

下面的HTML代码。

Answer 1

所以在一个范围内不应该是Element Not Found的原因。现在请尝试以下两件事：

使用等待：通常，元素加载需要一些时间，并且大多数元素未找到问题都已修复。

WebDriverWait wait = new WebDriverWait(driver, 10);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("StartDate_txtInput")));

使用getAttribute（）：您可能正在使用element.getText()来检索文本。有时在元素中没有文本，而在这种情况下，它只是设置为输入标记的属性， value 。尝试：

driver.findElement(By.id("StartDate_txtInput")).getAttribute("value");

Answer 2

通过ID

driver.findElement(By.id("StartDate_txtInput"));

或使用CSS选择器

input[id="StartDate_txtInput"]

或xpath

//input[@id='StartDate_txtInput']

或相对xpath

//div[@id='ContainerSizeGuide']/span/input[@id='StartDate_txtInput']

或

//div[@id='ContainerSizeGuide']/span/input

在使用这些路径之前检查iframe，如果iframe中的这个div首先转到iframe，那么请使用上面的nay路径。

driver.switchTo().frame((WebElement) By.id("iframeID"));

否则你明确等待使用webdriver

WebDriverWait wait=new WebDriverWait(driver, 5);
 wait.until(ExpectedConditions.visibilityOfElementLocated(null));

Answer 3

您必须使用属性值而不是文本。

代码如下：

String date=driver.findElement(By.id("StartDate_txtInput")).getAttribute("value");

使用Selenium Webdriver读取只读字段的值
