How to type in textbox using Selenium WebDriver (Selenium 2) with Java?

问题

I am using Selenium 2. But after running following code, i could not able to type in textbox.

    package Actor;
import org.openqa.*;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.junit.*;
import com.thoughtworks.selenium.*;
//import org.junit.Before;
public class Actor {
  public Selenium selenium;
  public WebDriver driver;

  @Before
  public void setup() throws Exception{
  driver = new FirefoxDriver();
      driver.get("http://www.fb.com");
  }
  @Test
  public void Test() throws Exception{
      //selenium.type("id=gs_htif0", "test");
      System.out.println("hi");
      // driver.findElement(By.cssSelector("#gb_1 > span.gbts")).click();
          selenium.waitForPageToLoad("300000000");

          WebElement email=driver.findElement(By.id("email"));

          email.sendKeys("nshakuntalas@gmail.com");
          driver.findElement(By.id("u_0_b")).click();
  }
  @After
  public void Close() throws Exception{
      System.out.println("how are you?");
  }

}

回答1:

This is simple if you only use Selenium WebDriver, and forget the usage of Selenium-RC. I'd go like this.

WebDriver driver = new FirefoxDriver();
WebElement email = driver.findElement(By.id("email"));
email.sendKeys("your@email.here");

The reason for NullPointerException however is that your variable driver has never been started, you start FirefoxDriver in a variable wb thas is never being used.

Thanks Friend, i got an answer. This is only possible because of your help. you all give me a ray of hope towards resolving this problem.

Here is the code:

package facebook;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.interactions.Actions;

public class Facebook {
    public static void main(String args[]){
        WebDriver driver = new FirefoxDriver();
        driver.get("http://www.facebook.com");
        WebElement email= driver.findElement(By.id("email"));
        Actions builder = new Actions(driver);
        Actions seriesOfActions = builder.moveToElement(email).click().sendKeys(email, "gati.naveen@gmail.com");
        seriesOfActions.perform();
        WebElement pass = driver.findElement(By.id("pass"));
        WebElement login =driver.findElement(By.id("u_0_b"));
        Actions seriesOfAction = builder.moveToElement(pass).click().sendKeys(pass, "naveench").click(login);
        seriesOfAction.perform();
        driver.
    }    
}

回答3:

You should replace WebDriver wb = new FirefoxDriver(); with driver = new FirefoxDriver(); in your @Before Annotation.

As you are accessing driver object with null or you can make wb reference variable as global variable.

回答4:

Try this :

    driver.findElement(By.id("email")).clear(); 
driver.findElement(By.id("email")).sendKeys("emal@gmail.com");

回答5:

Another way to solve this using xpath

WebDriver driver =  new FirefoxDriver();
driver.get("https://www.facebook.com/");
driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
driver.findElement(By.xpath(//*[@id='email'])).sendKeys("your@email.here");

Hope that will help. :)

回答6:

You can use JavaScript as well, in case the textfield is dithered.

WebDriver driver=new FirefoxDriver();
driver.get("http://localhost/login.do");
driver.manage().window().maximize();
RemoteWebDriver r=(RemoteWebDriver) driver;
String s1="document.getElementById('username').value='admin'";
r.executeScript(s1);
