在用selenium 1.X的时候常常会用到getEval()方法来执行一段js脚本来对页面进行处理,以处理一些遇到的问题。当然selenium webdriver也提供这样的一个方法:executeScript()
- import org.openqa.selenium.JavascriptExecutor;
- import org.openqa.selenium.WebDriver;
- public class SimpleExample {
- public staticvoid main(String[] args) {
- WebDriver driver = new FirefoxDriver();
- ((JavascriptExecutor)driver).executeScript("alert(\"hello,this is a alert!\")");
- }
- }
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
public class SimpleExample {
public static void main(String[] args) {
WebDriver driver = new FirefoxDriver();
((JavascriptExecutor)driver).executeScript("alert(\"hello,this is a alert!\")");
}
}
上面是一个最简单的例子,打开一个浏览器,然后弹层一个alert框。注意这里的driver要被强制转换成JavascriptExecutor。
下面演示在打开51.com首页如何得到帐号输入框中显示的字符,并打印输出。
- import org.openqa.selenium.JavascriptExecutor;
- import org.openqa.selenium.WebDriver;
- public class FirstExampe {
- public staticvoid main(String[] args) {
- WebDriver driver = new FirefoxDriver();
- driver.get("http://www.51.com");
- String js = "var user_input = document.getElementById(\"passport_51_user\").title;return user_input;";
- String title = (String)((JavascriptExecutor)driver).executeScript( js);
- System.out.println(title);
- }
- }
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
public class FirstExampe {
public static void main(String[] args) {
WebDriver driver = new FirefoxDriver();
driver.get("http://www.51.com");
String js = "var user_input = document.getElementById(\"passport_51_user\").title;return user_input;";
String title = (String)((JavascriptExecutor)driver).executeScript( js);
System.out.println(title);
}
}
输出结果为:
- 用户名/彩虹号/邮箱
