selenium webdriver(4)---模拟鼠标键盘操作

webdriver提供Actions来模拟鼠标悬浮、拖拽和键盘输入等操作，详细代码见org.openqa.selenium.interactions.Actions.本文通过几个实例来说明Actions的相关操作

 输入数据

需求:登录安居客网站，在二手房板块输入"@@@",点击搜索，正确跳转成功反之失败，大部分情况下我们这样写

//搜索二手房

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.WebElement;

public class NewTest{
    public static void main(String[] args) throws InterruptedException {
 
       System.setProperty ( "webdriver.chrome.driver" , 
       "C:\Program Files (x86)\Google\Chrome\Application\chromedriver.exe" );
       WebDriver driver = new ChromeDriver();
       driver.get("http://shanghai.anjuke.com");
       try{
           
          WebElement input=driver.findElement(By.xpath("//input[@id='glb_search0']"));
          WebElement search=driver.findElement(By.xpath("//input[@id='btnSubmit']"));
          input.sendKeys("@@@");
          search.click();
          if(driver.getTitle().contains("@"))
              System.out.println("搜索成功,跳转到"+driver.getTitle()+"页面");
          else
              System.out.println("搜索失败,跳转到了"+driver.getTitle()+"页面");
           
       }catch(Exception e){
           e.printStackTrace();
       }finally{
           Thread.sleep(3000);
           driver.quit(); 
       }
}

使用Actions类还可以这样写

import java.util.List;
import java.util.Set;

import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.interactions.Actions;
import org.openqa.selenium.WebElement;

public class NewTest{
    public static void main(String[] args) throws InterruptedException {
 
       System.setProperty ( "webdriver.chrome.driver" , 
       "C:\Program Files (x86)\Google\Chrome\Application\chromedriver.exe" );
       WebDriver driver = new ChromeDriver();
       driver.get("http://shanghai.anjuke.com");
       try{
           
          WebElement input=driver.findElement(By.xpath("//input[@id='glb_search0']"));
          WebElement search=driver.findElement(By.xpath("//input[@id='btnSubmit']"));
          
          //生成Actions实例对象
          Actions actions=new Actions(driver);
          //输入@@@点击搜索
          actions.keyDown(input, Keys.SHIFT).sendKeys("222")
          .keyUp(Keys.SHIFT).click(search).perform();
          
          if(driver.getTitle().contains("@"))
              System.out.println("搜索成功,跳转到"+driver.getTitle()+"页面");
          else
              System.out.println("搜索失败,跳转到了"+driver.getTitle()+"页面");
           
       }catch(Exception e){
           e.printStackTrace();
       }finally{
           Thread.sleep(3000);
           driver.quit(); 
       }
}

keyDown表示按下键盘，keyUp表示松开键盘。上述代码中先是执行keyDown，这时shift键按下后面的sendKeys内容也是在shift键按下的情况输入的，所以实际输入的是@@@.

 鼠标悬浮

需求:登录安居客首页，切换城市到杭州

import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.interactions.Actions;
import org.openqa.selenium.WebElement;

public class NewTest{
    public static void main(String[] args) throws InterruptedException {
 
       System.setProperty ( "webdriver.chrome.driver" , 
       "C:\Program Files (x86)\Google\Chrome\Application\chromedriver.exe" );
       WebDriver driver = new ChromeDriver();
       driver.get("http://shanghai.anjuke.com");
       try{
           
          WebElement city=driver.findElement(By.xpath("//a[@id='switch_apf_id_8']"));
          WebElement citys=driver.findElement(By.xpath("//div[@id='city-panel']"));
          WebElement cityOption=driver.findElement(By.xpath("//a[@title='杭州房产网']"));
          //生成Actions实例对象
          Actions actions=new Actions(driver);
          
          //鼠标悬浮到城市标签
          actions.moveToElement(city).perform();
          
          if(citys.isDisplayed())
              System.out.println("鼠标悬浮成功，城市模块的display:"+
                      citys.getCssValue("display"));
          else
              System.out.println("鼠标悬浮失败，城市模块的display:"+
                      citys.getCssValue("display"));
          //点击杭州
          actions.click(cityOption).perform();
          
          if(driver.getTitle().contains("杭州"))
              System.out.println("切换成功,跳转到"+driver.getTitle()+"页面");
          else
              System.out.println("切换失败,跳转到了"+driver.getTitle()+"页面");
           
       }catch(Exception e){
           e.printStackTrace();
       }finally{
           Thread.sleep(3000);
           driver.quit(); 
       }
}

 多选框

由于安居客网站没有这方面的例子，下面就采用YUI类库的DEMO界面来演示

import java.util.List;
import java.util.Set;

import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.interactions.Actions;
import org.openqa.selenium.WebElement;

public class NewTest{
    public static void main(String[] args) throws InterruptedException {
 
       System.setProperty ( "webdriver.chrome.driver" , 
       "C:\Program Files (x86)\Google\Chrome\Application\chromedriver.exe" );
       WebDriver driver = new ChromeDriver();
       driver.get("http://jqueryui.com/selectable/");
       try{
          WebElement frame=driver.findElement(By.xpath("//iframe[@class='demo-frame']"));
          driver.switchTo().frame(frame);
          List<WebElement> selects=driver
                  .findElements(By.xpath("//li[@class='ui-widget-content ui-selectee']"));
          //生成Actions实例对象
          Actions actions=new Actions(driver);
          actions.clickAndHold(selects.get(0)).clickAndHold(selects.get(1)).click().perform();
           
       }catch(Exception e){
           e.printStackTrace();
       }finally{
           Thread.sleep(3000);
           driver.quit(); 
       }
}

clickAndHold是点击并维持着点击的状态，上面代码效果如下图

 拖拽框体

响应式网站和OA系统这方面的需求较多，下面演示如何将拖拽对象拖拽到右下角

import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.interactions.Actions;
import org.openqa.selenium.WebElement;

public class NewTest{
    public static void main(String[] args) throws InterruptedException {
 
       System.setProperty ( "webdriver.chrome.driver" , 
       "C:\Program Files (x86)\Google\Chrome\Application\chromedriver.exe" );
       WebDriver driver = new ChromeDriver();
       driver.get("http://jqueryui.com/draggable/");
       try{
          WebElement frame=driver.findElement(By.xpath("//iframe[@class='demo-frame']"));
          driver.switchTo().frame(frame);
          WebElement dragTable=driver.findElement(By.xpath("//div[@id='draggable']"));
          //生成Actions实例对象
          Actions actions=new Actions(driver);
          //拖拽对象
          actions.dragAndDropBy(dragTable, 270, 170).perform();
           
       }catch(Exception e){
           e.printStackTrace();
       }finally{
           Thread.sleep(3000);
           driver.quit(); 
       }
}

其实dragAndDropBy方法就是clickAndHold和moveByOffset方法的组合而已

　　actions.dragAndDropBy(dragTable, 270, 170).perform();
　　actions.clickAndHold(dragTable).moveByOffset(270, 170).click().perform();

这两行代码功能是一样的,正所谓条条大路通罗马，我们只需选择最近、最安全的一条就好了。
