selenium web driver 使用JS修改input属性

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

 <html>

 <head>

 <title>this is a test </title>

 <script type="text/javascript">

 function display_alert()

   {

   alert("I am an alert box!!")

   }

 </script>

 </head>

 <body>

 <form action="form_action.jsp" method="get">

   <p>Name: <input type="text" id="fn" name="fullname" /></p>

   <p>Email: <input type="hidden" id="em"  name="email"  value="dbyl@dbyl.cn"/></p>

   <p><input type="submit" id="su" onclick="display_alert()" value="submit" /></p>

 </form>

 </body>

 </html>

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

 import org.openqa.selenium.Alert;

 import org.openqa.selenium.JavascriptExecutor;

 import org.openqa.selenium.By;

 import org.openqa.selenium.WebDriver;

 import org.openqa.selenium.WebElement;

 import org.openqa.selenium.chrome.ChromeDriver;

 //import org.openqa.selenium.ie.InternetExplorerDriver;

 //import org.openqa.selenium.remote.DesiredCapabilities;

 public class selenium {

     /**

      * @param args

      * @throws InterruptedException

      */

     public static void main(String[] args) throws InterruptedException {

         // TODO Auto-generated method stub

         String URL="E:\\2.html";

         //set web driver property

         System.setProperty("webdriver.chrome.driver", "E:\\chromedriver.exe");

         //create a WebDriver instance

         WebDriver driver = new ChromeDriver()    ;

         driver.manage().window().maximize();

         //load the URL

         driver.get(URL);

         //print current title

         System.out.println(driver.getTitle());

         //run JS to modify hidden element

         ((JavascriptExecutor)driver).executeScript("document.getElementById(\"em\").type ='text';");

         Thread.sleep(3000);

         //run JS and add a alert

         ((JavascriptExecutor)driver).executeScript("alert(\"hello,this is a alert!\");value=\"Alert\"");

         //wait for 3 seconds

          Thread.sleep(3000);

           //create a alert instance

           Alert alert1=driver.switchTo().alert();

           //print alert text

           System.out.println(alert1.getText());

           //click accept button

           alert1.accept();

             //create elements

             WebElement we=driver.findElement(By.id("fn"));

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

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

             // input something

             we.sendKeys("username test");

             Thread.sleep(3000);

             //print email tagname

             System.out.print("Email  isDislayed="+em.isDisplayed()+"\n");

             Thread.sleep(3000);

             //click submit button

             su.click();

             Thread.sleep(3000);

             Alert alert=driver.switchTo().alert();

             System.out.print( alert.getText());

             alert.accept();

             Thread.sleep(3000); 

             //close web browser

             driver.quit();

     }

 }

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!!
