无法使用Selenium-Java脚本在画布上绘制签名

Question

我在下面的代码中使用了多个点，但它仍然没有在画布上画一个点。它甚至没有认识到这一要素。还有其他自动化的选择吗？

WebElement element = driver.findElement(By.xpath("xpath of canvas"));

Actions builder = new Actions(driver);
Action drawAction = builder.moveToElement(element,135,15) //start points x axis and y axis. 
          .click()
          .moveByOffset(200, 60) // 2nd points (x1,y1)
          .click()
          .moveByOffset(100, 70)// 3rd points (x2,y2)
          .doubleClick()
          .build();
drawAction.perform();

Answer 1

使用单击并保持而不是单击，单击只会单击鼠标并突然释放它。

下面的代码是一个示例：

           System.setProperty("webdriver.chrome.driver","c:/chromedriver.exe");
           WebDriver driver = new ChromeDriver();
           driver.manage().window().maximize();
           driver.manage().timeouts().implicitlyWait(5,TimeUnit.SECONDS) ;
           driver.get("http://apps.zetakey.com/signsend/");


           Actions builder = new Actions(driver);
           Action drawAction = builder.moveToElement(driver.findElement(By.cssSelector("[id='newSignature']"))) //start points x axis and y axis. 
                     .clickAndHold()
                     .moveByOffset(-50, 60) // 2nd points (x1,y1)
                     .moveByOffset(-60, -70)// 3rd points (x2,y2)
                     .moveByOffset(150, 60) // 2nd points (x1,y1)
                     .moveByOffset(-60, -70)// 3rd points (x2,y
                     .doubleClick()
                     .build();
           drawAction.perform();
           Thread.sleep(6000);
