掌握设定页面对象的所有属性的方法，这个例子以设定文本框的可编辑状态和显示长度为目标。
被测试页面HTML代码：
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>设置文本框属性</title> </head> <body> <input type="text" id="text" value="watermelon" size=100>文本框</input> </body> </html>
实例代码：
package cn.om.webdriverapi;
import org.testng.annotations.Test;
import org.testng.annotations.BeforeMethod;
import org.openqa.selenium.By;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.AfterMethod;
public class TestDataPicker {
WebDriver driver;
String baseURL;
@Test
public void testdataPicker() {
driver.get(baseURL);
WebElement textbox = driver.findElement(By.id("text"));
setAttribute(textbox, driver, "value", "文本框的文字和长度属性已经被修改");
setAttribute(textbox, driver, "size", "10");
RemoveAttribute(textbox, driver, "size");
}
public void setAttribute(WebElement e, WebDriver d, String attributeName, String value) {
JavascriptExecutor js = (JavascriptExecutor) d;
// 执行JavaScriptdiamante修改页面元素属性。arguments[0]-[2]后面会用e,attributeName,value替换并执行
js.executeScript("arguments[0].setAttribute(arguments[1],arguments[2])", e, attributeName, value);
}
public void RemoveAttribute(WebElement e, WebDriver d, String attributeName) {
JavascriptExecutor js = (JavascriptExecutor) d;
// 执行JavaScriptdiamante修改页面元素属性。arguments[0]-[2]后面会用e,attributeName,value替换并执行
js.executeScript("arguments[0].removeAttribute(arguments[1])", e, attributeName);
}
@BeforeMethod
public void beforeMethod() {
baseURL = "file:///F:/workspace/WebDriver%20API/dataPicker.html";
System.setProperty("webdriver.firefox.bin", "D:/Mozilla Firefox/firefox.exe");
driver = new FirefoxDriver();
}
@AfterMethod
public void afterMethod() {
driver.quit();
}
