# selenium定位元素，合理设置等待时间 #

selenium定位元素，有时需要设置等待时间，但是时间不定，可以按照依次递增等待时间的方式，设置等待，大体代码如下

package util;
    
    import java.util.List;
    
    import org.apache.log4j.Logger;
    import org.openqa.selenium.By;
    import org.openqa.selenium.WebDriver;
    import org.openqa.selenium.WebElement;
    import org.openqa.selenium.firefox.FirefoxDriver;
    
    public class ElementLocateHelper {
    	private static WebDriver driver = null;
    	private static Logger logger = ConfigHelper.logger;
    	static {
    		System.setProperty("webdriver.firefox.bin", ConfigHelper.getObject("FIREFOX_PATH"));
    		driver = new FirefoxDriver();
    	}
    	public static void setWebDriver(WebDriver driver){
    		ElementLocateHelper.driver = driver;
    	}
    	public static WebDriver getWebDriver(){
    		return ElementLocateHelper.driver;
    	}
    	//查找页面元素
    	public static WebElement FindWebElement(String elementLocation) throws InterruptedException{
    		boolean flag = false;
    		int count = 10;
    		while(!flag){
    			try{
    				driver.findElement(By.xpath(elementLocation));
    				flag = true;
    			}catch(org.openqa.selenium.NoSuchElementException e){
    				Thread.sleep(500+count*100);
    				count--;
    				if(count == 0){
    					logger.warn(elementLocation +"is not exist!");
    					flag =true;
    					return null;
    				}
    			}
    		}
    		return  driver.findElement(By.xpath(elementLocation));
    	}
    	
    	//查找页面元素，并且点击
    	public static void FindWebElementAndClick(String elementLocation) throws InterruptedException{
    		boolean flag = false;
    		int count = 10;
    		while(!flag){
    			try{
    				driver.findElement(By.xpath(elementLocation)).click();
    				flag = true;
    			}catch(org.openqa.selenium.NoSuchElementException e){
    				Thread.sleep(500+count*100);
    				count--;
    				if(count == 0){
    					logger.warn(elementLocation +"is not exist!");
    					flag =true;
    				}
    			}
    		}
    	}
    	//click2暂时没用
    	public static void FindWebElementAndClick2(String elementLocation)throws InterruptedException {
    		boolean flag = false;
    		int count = 10;
    		while(!flag){
    			try{
    				driver.findElement(By.cssSelector(elementLocation)).click();
    				flag = true;
    			}catch(org.openqa.selenium.NoSuchElementException e){
    				Thread.sleep(500+count*100);
    				count--;
    				if(count == 0){
    					logger.warn(elementLocation +"is not exist!");
    					flag =true;
    				}
    			}
    		}
    	}
    	//查找页面元素，并且发送内容
    	public static void FindWebElementAndSendKeys(String elementLocation, String elementKey) throws InterruptedException{
    		boolean flag = false;
    		int count = 10;
    		while(!flag){
    			try{
    				driver.findElement(By.xpath(elementLocation)).sendKeys(elementKey);
    				flag = true;			
    			}catch(org.openqa.selenium.NoSuchElementException e){
    				Thread.sleep(500+count*100);
    				count--;
    				if(count == 0){
    					logger.warn(elementLocation +"is not exist!");
    					flag =true;
    				}
    			}
    		}	
    	}
    
    }

注：当然，可以设置一个Thread.sleep（XXX），XXX固定的时间，视情况而定
