Handling ListBoxes in selenium

ListBox is an element where user can select/deselect one or more items from it.

To identify the ListBox on webpage, look for select tag and attribute should be 'multiple' to select multiple items and there will be option tag which contains each item in it.[as shown below]

How can we identify a ListBox on webpage:

WebElement val=driver.findElement(By.id("tools"));

Now let's get all the options from the ListBox

Select s=new Select(val);
List<WebElement> allvals=s.getOptions();

allvals is having list of all the ListBox items in it.

Let's see some of the operations with ListBox

package controls;

import java.util.List;
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.support.ui.Select;

public class ListBox {

 public static void main(String[] args) throws InterruptedException {
  WebDriver driver=new FirefoxDriver();
  driver.manage().window().maximize();
  driver.get("http://www.qavalidation.com/p/demo.html");
 
  WebElement val=driver.findElement(By.id("tools"));
  Select s=new Select(val);
  List<WebElement> allvals=s.getOptions();
 
  for(int i=0;i<allvals.size();i++)
  {
   Thread.sleep(1000);
   System.out.println("CheckBox:"+ allvals.get(i).getAttribute("value"));
   s.selectByIndex(i); //select one by one
  }
  
  //s.deselectAll();
  s.deselectByIndex(1);//deselect 2nd item
  s.deselectByIndex(3);//deselect 4th item
  
  //select checkbox having value='Selenium'
  List<WebElement> selected = s.getAllSelectedOptions();
  for(WebElement e:selected)
  {
   if(e.getText().equals("Selenium")==false)
    s.selectByVisibleText("Selenium");
  }
  //s.selectByValue(value)
  
  System.out.println("Selected CheckBoxes only");
  List<WebElement> selected1 = s.getAllSelectedOptions();
  for(WebElement el:selected1)
  {
   System.out.println("CheckBox:"+ el.getAttribute("value"));
  }
 }
}

OutPut:

CheckBox:qtp
CheckBox:selenium
CheckBox:white
CheckBox:jmeter
CheckBox:telerik
CheckBox:codedui
Selected CheckBoxes only
CheckBox:qtp
CheckBox:selenium
CheckBox:white
CheckBox:telerik
CheckBox:codedui
