i and not able to scroll side bar in selenium java-CodePudding

i was trying to do with eventfiringwebdriver but not able to use it showing unwanted errors

      EventFiringWebDriver EventFiringWebDriver = new EventFiringWebDriver(driver);
      
      EventFiringWebDriver.executeScript

("document.querySelector('/html/body/begin:/div[1]/div[2]/div[2]/div)') ;

second method i was trying  by javascript and actions
    JavascriptExecutor jre = (JavascriptExecutor)driver;
    jre.executeScript("window.scrollBy(0,1000)");
    
    
    WebElement extension =  
    driver.findElement(By.xpath("/html/body/begin:/div[1]/div[2]/div[2]/div"));
    Thread.sleep(2000);
    jre.executeScript("argument[2000].scrollIntoView();", extension);

CodePudding user response：

To path the WebElement as argument for js script evaluation next syntax should be used:

WebElement extension =  
driver.findElement(By.xpath("/html/body/begin:/div[1]/div[2]/div[2]/div"));
Thread.sleep(2000);
jre.executeScript("arguments[0].scrollIntoView();", extension);

argument[2000] changed to arguments[0].

So, this command shouldn't throw errors any more.

Args passing to JavascriptExecutor.executeScript

This illustrates how to pass multiple args for evaluation, and why arguments[0] should be used for the case when we pass a single argument.

int result = jre.executeScript("return (arguments[0]   arguments[1]   arguments[2])", 2, 5, 10);
System.out.println("Result: "   result);

will print:

Result: 17

You can use JS to scroll to specific location on the page (top/bottom) or you can scroll to element.

public void scrollToTop() {
     jsExecutor.executeScript("window.scrollTo(0,0)");
}

public void scrollToBottom() {
     jsExecutor.executeScript("window.scrollTo(0,document.body.scrollHeight)");
}

public void scrollToOffset(int x, int y) {
     jsExecutor.executeScript("window.scrollTo("   x   ","   (y - 100)   ")");
}
public void scrollToElement(WebElement webElement) {
     scrollToOffset(webElement.getLocation().x, webElement.getLocation().y);
}

public void scrollToElement(By locator) {
     scrollToTop();
     scrollToElement(findElement(locator));
}
