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

 1 <html>
 2 <head>
 3 <title>this is a test </title>
 4 <script type="text/javascript">
 5 function display_alert()
 6   {
 7   alert("I am an alert box!!")
 8   }
 9 </script>
10 </head>
11 <body>
12 <form action="form_action.jsp" method="get">
13   <p>Name: <input type="text" id="fn" name="fullname" /></p>
14   <p>Email: <input type="hidden" id="em"  name="email"  value="dbyl@dbyl.cn"/></p>
15   <p><input type="submit" id="su" onclick="display_alert()" value="submit" /></p>
16   
17 </form>
18 </body>
19 </html>
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;
 9 
10 public class selenium {
11 
12     /**
13      * @param args
14      * @throws InterruptedException 
15      */
16     public static void main(String[] args) throws InterruptedException {
17         // TODO Auto-generated method stub
18 
19         String URL="E:\\2.html";
20         //set web driver property 
21         System.setProperty("webdriver.chrome.driver", "E:\\chromedriver.exe"); 
22         //create a WebDriver instance
23         WebDriver driver = new ChromeDriver()    ;
24         driver.manage().window().maximize();
25         
26         //load the URL
27         driver.get(URL);
28         //print current title
29         System.out.println(driver.getTitle());
30         //run JS to modify hidden element 
31         ((JavascriptExecutor)driver).executeScript("document.getElementById(\"em\").type ='text';");
32         Thread.sleep(3000);
33         //run JS and add a alert
34         ((JavascriptExecutor)driver).executeScript("alert(\"hello,this is a alert!\");value=\"Alert\"");
35              
36         //wait for 3 seconds
37          Thread.sleep(3000);
38          
39          
40           //create a alert instance
41           Alert alert1=driver.switchTo().alert();
42           //print alert text
43           System.out.println(alert1.getText());
44           //click accept button
45           alert1.accept();
46          
47             //create elements
48             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 something 
52             we.sendKeys("username test");
53             Thread.sleep(3000);
54             //print email tagname
55             System.out.print("Email  isDislayed="+em.isDisplayed()+"\n");
56             Thread.sleep(3000);
57             //click submit button
58             su.click();
59             Thread.sleep(3000);
60             
61             Alert alert=driver.switchTo().alert();
62             System.out.print( alert.getText());
63             alert.accept();
64             
65             Thread.sleep(3000); 
66             
67             //close web browser
68             driver.quit();
69           
70     }
71 
72 }


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!!
