WebDriver脚本，用于单击除特定名称不起作用的所有链接

Question

I am in process of learning Selenium WebDriver 2 using Java/Junit with IntelliJ IDEA.

The sample page I am using for creating scripts is http://newtours.demoaut.com/

I am trying to create a script that will click on all the links on the page EXCEPT the "SUPPORT" link.

I've imported all the necessary libraries and

Here is the code that I tried to use but it gives an error:

public class AllLinksExceptSupport{

WebDriver driver= new FirefoxDriver();
String url="http://newtours.demoaut.com/";

@Before
public void loadhomepage()
{
driver.get(url);

@Test
public void allexceptregister(){
   List<WebElement> alllinks = driver.findElements(By.tagName("a"));
for (int i =0; i<= alllinks.size()-1; i++){
    String oflinks = alllinks.get(i).getText();
    if(oflinks.equals("SUPPORT")){
      continue;
    }
     alllinks.get(i).click();
}
}
}

Here is the error message:

org.openqa.selenium.StaleElementReferenceException: Element not found in the cache - perhaps the page has changed since it was looked up.

Can you please advise on what I'm doing wrong and what needs to be changed in the code/logic?

Thank you.

The issue you're encountering is that when you click a link, you're leaving the page. This makes the collection of elements in your List "stale".

This is an approach that should work for you. Of course, this assumes that all of the links have different link text.

List<WebElement> allLinks = driver.findElements(By.tagName("a"));
String ofLinks[] = new String[allLinks.size()];
for (int i = 0; i < allLinks.size(); i++){
    if(!allLinks.get(i).getText().equals("SUPPORT")){
       ofLinks[i] = allLinks.get(i).getText();
    }
}

for (int i = 0; i < allLinks.size(); i++){
    if (ofLinks[i] != null){
        driver.findElement(By.LinkText(ofLinks[i])).click();
    }
    driver.findElement(By.linkText("Home")).click();
}
