无法使用Selenium WebDriver 2.31(JRE 7)定位元素

问题描述：

我正在尝试使在网站上预订公交车票的场景自动化.我在Eclipse中使用了Selenium WebDriver，当我尝试查找元素(即乘客姓名")时，没有编译错误，但是在执行时显示了诸如"Exception in thread "main" org.openqa.selenium.NoSuchElementException: Unable to locate element: {"method":"xpath","selector":"//input[@name='i_passengerAge']"}"的错误.

I'm trying to automate a scenario which books a bus ticket in a website. I'm using Selenium WebDriver with Eclipse and when i try to locate the element, i.e. 'Passenger name', no compilation errors, but while executing it shows an error such as "Exception in thread "main" org.openqa.selenium.NoSuchElementException: Unable to locate element: {"method":"xpath","selector":"//input[@name='i_passengerAge']"}".

下面的HTML和Java代码，我也需要一个快速的解决方案.

HTML and Java code below, also i need an hasty solution for this.

我的系统信息:

Windows 7
Selenium WebDriver 2.31
Eclipse FW

网页的HTML:

<input name="i_passengerName" id="i_passengerName" maxlength="30" class="inputclass pageRequired commonInputStyle" title="Please enter your name!" type="text">

<input name="i_passengerAge" id="i_passengerAge" maxlength="2" size="4" class="inputclass fillAge digits commonInputStyle" type="text">

我的自动化脚本:

WebElement PD_Name = driver.findElement(By.name("i_passengerName"));
PD_Name.sendKeys(new String[] {"Testing"});
PD_Name.submit();

WebElement PD_Age = driver.findElement(By.name("i_passengerAge"));
PD_Age.sendKeys(new String[] {"45"});
PD_Age.submit();

答

我希望您尝试使用By.id，By.cssSelector或By.xpath来获取元素.

I hope you've tried to get the element with By.id, By.cssSelector or By.xpath.

当心submit()方法.因为它会自动搜索要发送的表单，有时可能会失败.这就是为什么我更喜欢老式的click().

Watch out about the submit() method. Because it search automaticaly the form to send and sometimes it may fail. That's why i prefere the good old click().

By.id:

WebElement PD_Name=driver.findElement(By.id("i_passengerName"));
PD_Name.sendKeys("Testing");
PD_Name.click();

通过.xpath:

WebElement PD_Name=driver.findElement(By.xpath("//input[@name='i_passengerName']"));
PD_Name.sendKeys("Testing");
PD_Name.click();

对于cssSelector方式，您可以此处.

For the cssSelector way, you can take a look here.

告诉我是否有所改善. =)

Tell me if it improved. =)

实际上，没有 i_passengerGender
