In selenium we will identify the element by using firebug or xpath.

The below script explains you how to get the values in a dropdown and print the values to a notepad or excel sheet using the xpath...




import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;

import com.thoughtworks.selenium.*;

import org.openqa.selenium.server.*;
import org.testng.annotations.*;


public class Dropdowngooglexpath {
public Selenium selenium;
public SeleniumServer seleniumserver;

  @BeforeClass
  public void setUp() throws Exception {
RemoteControlConfiguration rc = new RemoteControlConfiguration();
seleniumserver = new SeleniumServer(rc);
selenium = new DefaultSelenium("localhost", 4444, "*firefox", "http://");
seleniumserver.start();
selenium.start();
}

@Test
public void testDropdowngoogle()throws Exception {
selenium.open("http://www.google.com");
//click on Advanced Search Window
    selenium.click("link=Advanced Search");    
    selenium.waitForPageToLoad("5000");
     //Print all the available options from the results dropdown in the google advanced search page
//here i am using xpath to identify the element
    String[] option = selenium.getSelectOptions("xpath=/html/body/table[2]/tbody/tr/td/table/tbody/tr/td/div/form/div/table[2]/tbody/tr[1]/td[2]/select");      
    //The above command returns a array of strings(options)
   //write results to excel and note pad
    File file = new File("C:/Dropdownvalues.xls");//excel
    File file1 = new File("C:/Dropdownvalues.txt");//notepad
    BufferedWriter out = new BufferedWriter(new FileWriter(file));//excel
    BufferedWriter out1 = new BufferedWriter(new FileWriter(file1));//notepad
    out.write("Options in drop down\n");//Excel
    out1.write("Options in drop down\n");//notepad
    for (int i = 0; i < option.length; i++) {
        System.out.println("Option: " + i + " is" + option[i]);
        out.write(""+option[i]);
        out.newLine();      
        out1.write(""+option[i]);
        out1.newLine();      
    }
    out.close();//excel
    out1.close();//notepad
  }
 @AfterClass
 public void tearDown()throws Exception {
selenium.stop();
seleniumserver.stop();

 }
 }

Here i am writing steps how to verify the check box is checked or not?



import com.thoughtworks.selenium.*;

import org.openqa.selenium.server.*;
import org.testng.annotations.*;


public class Checkbox {
public Selenium selenium;
public SeleniumServer seleniumserver;

  @BeforeClass
  public void setUp() throws Exception {
RemoteControlConfiguration rc = new RemoteControlConfiguration();
seleniumserver = new SeleniumServer(rc);
selenium = new DefaultSelenium("localhost", 4444, "*firefox", "http://");
seleniumserver.start();
selenium.start();
}

@Test
public void testCheckbox()throws Exception {

selenium.open("http://www.google.com");
selenium.windowMaximize();
selenium.click("link=Search settings");
selenium.waitForPageToLoad("50000");
/*Here i am verifying the check box for English. English check
box is already checked so if case will be executed*/
//here pen is the id of the check box
if(selenium.isChecked("pen"))
{
System.out.println("check box already checked");
}
else
{
System.out.println("Check box not checked");
}
}
 @AfterClass
 public void tearDown()throws Exception {
selenium.stop();
seleniumserver.stop();

 }
 }

Will update the post once i know how to use Java script in selenium script...

It is not an easy talk to identify the frame name or ID..when the frame name is changing dynamically...
For example login in gmail and try to compose a mail...Compose mail button is kept in a separate frame..for the we need to select that frame...first we need to select that frame and later we need to click on that button..

i am searching for how to identify the frame..after gettign i will update the post....

****Will post soon******

I saw many posts on identifying window Name, ID and Title or Attribute....but all are giving Syntax...We can find that syntax in Selenium document. In this post, I would like to give an example how to identify window Name, ID and Title or Attribute....
*** coming soon ***

• Actions are commands that generally manipulate the state of the application. They do things like “click this link” and “select that option”. If an Action fails, or has an error, the execution of the current test is stopped.

• Accessors examine the state of the application and store the results in variables, e.g. “storeTitle”. They are also used to automatically generate Assertions.
• Assertions are like Accessors, but they verify that the state of the application conforms to what is expected. Examples include “make sure the page title is X” and “verify that this checkbox is checked”.

verifyText

//div//a[2]

Login

goBackAndWait
verifyTextPresent		Welcome to My Home Page
type	id=phone	(555) 666-7066
type	id=address1	${myVariableAddress}

• a locator for identifying a UI element within a page.
• a text pattern for verifying or asserting expected page content

a text pattern or a selenium variable for entering text in an input field or for selecting an option from an option list.









A file similar to this would allow running the tests all at once, one after another, from the Selenium-IDE.
Now that you’ve seen an introduction to Selenium, you’re ready to start writing your first scripts. We recommend beginning with the Selenium IDE and its context-sensitive, right-click, menu. This will allow you to get familiar with the most common Selenium commands quickly, and you can have a simple script done in just a minute or two. 
This command takes a script as its first parameter. Embedding JavaScript within Selenese is covered in the next section. StoreEval allows the test to store the result of running the script in a variable.
