Unable to locate an Element By ID in Selenium
提问by meepin
I am having trouble locating the login id using selenium. I got this work on a windows computer before, but I am trying to do this at home on my mac and I am not able to find the element by id anymore. I have tried implementing driverwait what was suggested by a lot of people online, but I am still encountering the same errors. Any help will be appreciated.
我在使用 selenium 定位登录 ID 时遇到问题。我之前在 Windows 计算机上完成了这项工作，但我试图在家里的 mac 上完成这项工作，但我无法再通过 id 找到该元素。我已经尝试实现 driverwait 网上很多人的建议，但我仍然遇到相同的错误。任何帮助将不胜感激。
public class mainEntry {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
String webPage;
//theDriver driverCMD = new theDriver();
WebDriver driverCMD = new FirefoxDriver();
login start = new login("https://jira.arbonne.com/", driverCMD);
start.loginWithUser();
}
}
The Login page object is below:
登录页面对象如下：
public class login {
String webpage;
WebDriver driverCMD;
login(String webpage, WebDriver driverCMD)
{
this.webpage = webpage;
this.driverCMD = driverCMD;
}
public void loginWithUser()
{
WebDriverWait wait = new WebDriverWait(driverCMD, 300); // The int here is the maximum time in seconds the element can wait.
try
{
driverCMD.get(webpage);
//driverCMD.driver.get(webpage);
}
catch(Exception e)
{
System.out.print("could not get webpage");
}
try{
wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("login-form-username")));
WebElement username = driverCMD.findElement(By.id("login-form-username"));
username.sendKeys("test");
//WebElement password = driverCMD.driver.findElement(By.id("login-form-password"));
//password.sendKeys("test");
//password.submit();
}
catch(Exception e)
{
System.out.println("could not login");
}
}
}
Thank you for you help.
谢谢你的帮助。

Reason 1:
原因一：
Waiting for the element to be loaded. Use
等待元素被加载。用
WebDriverWait wait = new WebDriverWait(driver, 4000);
wait.until(ExpectedConditions.visibilityOfElementLocated((By.id("id"))));
Reason 2:
原因2：
Check to see if <input id="id" class="p-field span12" type="text">is in any frame.
检查是否<input id="id" class="p-field span12" type="text">在任何帧中。
If yes use
如果是，请使用
driver.switchTo.frame("frameName");
before using
使用前
driver.findElement(By.id("id")).sendKeys("input key");
