selenium webdriver——JS滾動到最底部

JS控制滾動條的位置：

window.scrollTo(x,y);

 

豎向滾動條置頂 window.scrollTo(0,0);

豎向滾動條置底 window.scrollTo(0,document.body.scrollHeight)

 

JS控制TextArea滾動條自動滾動到最下部

document.getElementById('textarea').scrollTop = document.getElementById('textarea').scrollHeight

 

例子：

import org.openqa.selenium.By;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.TimeoutException;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.ExpectedCondition;
import org.openqa.selenium.support.ui.WebDriverWait;
import org.testng.Assert;

            //等待元素頁面加載
            waitForElementToLoad(driver, 10, By.xpath(".//*[@id='1']/h3/a[1]"));
            
            //將頁面滾動條拖到底部
            driver_js.executeScript("window.scrollTo(0,document.body.scrollHeight)");
            
            //#將頁面滾動條拖到頂部
            driver_js.executeScript("window.scrollTo(0,0)");
            
            
        }catch (Exception e){
            e.printStackTrace();
        }
        driver.quit();    
    }
    
    /**
     * 在給定的時間內去查找元素，如果沒找到則超時，拋出異常
     * */
    public static void waitForElementToLoad(WebDriver driver, int timeOut, final By By) {
        try {
            (new WebDriverWait(driver, timeOut)).until(new ExpectedCondition<Boolean>() {

                public Boolean apply(WebDriver driver) {
                    WebElement element = driver.findElement(By);
                    return element.isDisplayed();
                }
            });
        } catch (TimeoutException e) {
            Assert.fail("超時!! " + timeOut + " 秒之后還沒找到元素 [" + By + "]");

        }
    }
}

  waitForElementToLoad()函數是為了保證頁面元素已加載完成，以便執行JS代碼

 

Python代碼

from selenium import  webdriver
from selenium.webdriver.support.wait import WebDriverWait
driver = webdriver.Firefox()
driver.get("http://www.baidu.com")
driver.execute_script("document.getElementById(\"kw\").value=\"selenium\"")
WebDriverWait(driver, 10).until(lambda driver : driver.find_element_by_xpath(".//*[@id='container']/div[2]/div/div[2]"))
driver.execute_script("window.scrollTo(0,document.body.scrollHeight)")
driver.quit()
