其實(shí)光看字面上的理解sendKeys這個(gè)api感覺(jué)只有輸入字符這一個(gè)功能，其實(shí)這樣理解是錯(cuò)誤的其實(shí)這個(gè)api的真正作用是模擬鍵盤的操作(包含了輸入字符)，不過(guò)輸入字符是其主要的功能，下面介紹一下其他的用法：
　　這里直接上代碼了
package org.coderinfo.demo;
import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class ApiSendKeys {
private static final String URL = "file:///C:/user/Desktop/Selenium/operate.html";
public static void main(String[] args) {
WebDriver driver = new ChromeDriver(); // create a chrome driver
driver.manage().window().maximize(); // max size the chrome window
driver.get(URL); // open URL with the chrome browser
try {
Thread.sleep(2000);  // wait for page loading
} catch (InterruptedException e) {
e.printStackTrace();
}
driver.findElement(By.id("UserName")).sendKeys("coderinfo");  // Get input element and input some words
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
e.printStackTrace();
}
driver.findElement(By.id("UserName")).sendKeys(Keys.chord(Keys.CONTROL + "a")); // Use sendKeys to select all the content
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
e.printStackTrace();
}
driver.findElement(By.id("UserName")).sendKeys(Keys.chord(Keys.CONTROL + "x")); // Use sendKeys to cut the content
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
e.printStackTrace();
}
driver.findElement(By.id("UserEmail")).sendKeys(Keys.chord(Keys.CONTROL + "v"));   // Use sendKeys to copy the content
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
e.printStackTrace();
}
driver.quit();  // close webdriver
}
}
