selenium+java 判断元素是否存在

步骤1：创建一个判断类

package Help;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;

public class HaveOrNo {
	public Boolean check(WebDriver driver,By seletor) {
		try {
			driver.findElement(seletor);
			return true;
		} catch (Exception e) {
			// TODO: handle exception
			return false;
		}
	}

}

步骤2：然后调用

HaveOrNo checkElement=new HaveOrNo();
By seletor=new By.ByXPath("//*[@id=\"signup-form\"]/div[3]/input") ;
driver.manage().window().maximize();
if(checkElement.check(driver, seletor)) {
              //此元素存在
        }
   else{
              //此元素不存在
        }
