思路：
- 引用jQuery类库
- 用jQuery代码改变元素属性
现以改变百度页面属性为例，删除id属性，将百度输入框及按钮背景色改为红色
代码如下：
package com.webdirver.test;import org.apache.commons.lang3.StringUtils;import org.openqa.selenium.JavascriptExecutor;import org.openqa.selenium.WebDriver;import org.openqa.selenium.chrome.ChromeDriver;/** * selenium 引用jQuery改变页面元素属性 * ?* @author Administrator * */public class LoadJQuery { ???private static WebDriver driver; ???/** ????* 向当前页面注入JQuery，并返回加载是否成功 ????* ?????* @return ????*/ ???public boolean injectjQuery() { ???????try { ???????????String injectJQuery = "var script = document.createElement(‘script‘);" ???????????????????+ "var filename = \"http://code.jquery.com/jquery-1.10.1.min.js\";" ???????????????????+ "script.setAttribute(\"type\",\"text/javascript\");" ???????????????????+ "script.setAttribute(\"src\", filename);" ???????????????????+ "if (typeof script!=‘undefined‘){" ???????????????????+ "document.getElementsByTagName(\"head\")[0].appendChild(script);" ???????????????????+ "}"; ???????????((JavascriptExecutor) driver).executeScript(injectJQuery); ???????????Thread.sleep(3000); ???????} catch (InterruptedException e) { ???????????e.printStackTrace(); ???????} ???????// 判断JQuery是否加载成功 ???????Boolean loaded = true; ???????String s = (String) (((JavascriptExecutor) driver) ???????????????.executeScript("return typeof jQuery")); ???????if (!StringUtils.trimToEmpty(s).equals("function")) ???????????loaded = false; ???????return loaded; ???} ???public static void main(String[] args) { ???????System.setProperty("webdriver.chrome.driver", "chromedriver.exe"); ???????driver = new ChromeDriver(); ???????driver.get("https://www.baidu.com/"); ???????// 删除input标签下的id属性 ???????JavascriptExecutor js = (JavascriptExecutor) driver; ???????String changeDisplay = " $(‘input‘).removeAttr(‘id‘);"; ???????js.executeScript(changeDisplay); ???????js = (JavascriptExecutor) driver; ???????// 将百度按钮改成红色 ???????String changeinput = "$(\"input\").attr(\"style\",\"background:red\");"; ???????js.executeScript(changeinput); ???}}运行结果如下：
