Selenium web driver 使用JS修改input属性

1 import org.openqa.selenium.Alert;2 import org.openqa.selenium.JavascriptExecutor;3 import org.openqa.selenium.By;4 import org.openqa.selenium.WebDriver;5 import org.openqa.selenium.WebElement;6 import org.openqa.selenium.chrome.ChromeDriver;7 //import org.openqa.selenium.ie.InternetExplorerDriver;8 //import org.openqa.selenium.remote.DesiredCapabilities;910 public class selenium {1112     /**13      * @param args14      * @throws InterruptedException15      */16     public static void main(String[] args) throws InterruptedException {17         // TODO Auto-generated method stub1819         String URL="E:\\2.html";20         //set web driver property21         System.setProperty("webdriver.chrome.driver", "E:\\chromedriver.exe");22         //create a WebDriver instance23         WebDriver driver = new ChromeDriver()    ;24         driver.manage().window().maximize();2526         //load the URL27         driver.get(URL);28         //print current title29         System.out.println(driver.getTitle());30         //run JS to modify hidden element31         ((JavascriptExecutor)driver).executeScript("document.getElementById(\"em\").type ='text';");32         Thread.sleep(3000);33         //run JS and add a alert34         ((JavascriptExecutor)driver).executeScript("alert(\"hello,this is a alert!\");value=\"Alert\"");3536         //wait for 3 seconds37          Thread.sleep(3000);383940           //create a alert instance41           Alert alert1=driver.switchTo().alert();42           //print alert text43           System.out.println(alert1.getText());44           //click accept button45           alert1.accept();4647             //create elements48             WebElement we=driver.findElement(By.id("fn"));49             WebElement su=driver.findElement(By.id("su"));50             WebElement em=driver.findElement(By.id("em"));51             // input something52             we.sendKeys("username test");53             Thread.sleep(3000);54             //print email tagname55             System.out.print("Email  isDislayed="+em.isDisplayed()+"\n");56             Thread.sleep(3000);57             //click submit button58             su.click();59             Thread.sleep(3000);6061             Alert alert=driver.switchTo().alert();62             System.out.print( alert.getText());63             alert.accept();6465             Thread.sleep(3000);6667             //close web browser68             driver.quit();6970     }7172 } 　　可以通过js修改input的type value,执行js只需要export　　import org.openqa.selenium.JavascriptExecutor;　　运行结果如下：　　Starting ChromeDriver (v2.9.248315) on port 30175　　this is a test　　hello,this is a alert!　　Email  isDislayed=true　　I am an alert box!! 　　selenium获取input时候，发现type=”hidden” 的input无法修改value,经牛人指点，可以使用js修改　　首先html源文件如下，设置为text 、hidden、submit　　View Code　　在浏览器加载之后如下：　　这时候email 不能对外显示　　使用selenium，代码如下1 import org.openqa.selenium.Alert;2 import org.openqa.selenium.JavascriptExecutor;3 import org.openqa.selenium.By;4 import org.openqa.selenium.WebDriver;5 import org.openqa.selenium.WebElement;6 import org.openqa.selenium.chrome.ChromeDriver;7 //import org.openqa.selenium.ie.InternetExplorerDriver;8 //import org.openqa.selenium.remote.DesiredCapabilities;910 public class selenium {1112     /**13      * @param args14      * @throws InterruptedException15      */16     public static void main(String[] args) throws InterruptedException {17         // TODO Auto-generated method stub1819         String URL="E:\\2.html";20         //set web driver property21         System.setProperty("webdriver.chrome.driver", "E:\\chromedriver.exe");22         //create a WebDriver instance23         WebDriver driver = new ChromeDriver()    ;24         driver.manage().window().maximize();2526         //load the URL27         driver.get(URL);28         //print current title29         System.out.println(driver.getTitle());30         //run JS to modify hidden element31         ((JavascriptExecutor)driver).executeScript("document.getElementById(\"em\").type ='text';");32         Thread.sleep(3000);33         //run JS and add a alert34         ((JavascriptExecutor)driver).executeScript("alert(\"hello,this is a alert!\");value=\"Alert\"");3536         //wait for 3 seconds37          Thread.sleep(3000);383940           //create a alert instance41           Alert alert1=driver.switchTo().alert();42           //print alert text43           System.out.println(alert1.getText());44           //click accept button45           alert1.accept();4647             //create elements48             WebElement we=driver.findElement(By.id("fn"));49             WebElement su=driver.findElement(By.id("su"));50             WebElement em=driver.findElement(By.id("em"));51             // input something52             we.sendKeys("username test");53             Thread.sleep(3000);54             //print email tagname55             System.out.print("Email  isDislayed="+em.isDisplayed()+"\n");56             Thread.sleep(3000);57             //click submit button58             su.click();59             Thread.sleep(3000);6061             Alert alert=driver.switchTo().alert();62             System.out.print( alert.getText());63             alert.accept();6465             Thread.sleep(3000);6667             //close web browser68             driver.quit();6970     }7172 }
