selenium如何使用web驱动程序Java关闭网页上的模式对话框

Question

我试图关闭网页上出现的对话框，该对话框主要使用SeleniumWeb驱动程序和Java，但没有任何结果。我的代码：

   @When("^I am on second page I click on close button in pop up$")
    public void i_am_on_second_page_I_click_on_close_button_in_pop_up() throws Throwable {
        driver.findElement(By.xpath("//*[@id=\"ngdialog2\"]/div[2]/promo-banner/div/div/div[2]/div/dialog-body/div[1]/div[2]")).click();
        driver.switchTo().activeElement();

我得到：java.lang.NullPointerException

java.lang.NullPointerException
    at SeconPage.i_am_on_second_page_I_click_on_close_button_in_pop_up(SeconPage.java:17)
    at ✽.When I am on second page I click on close button in pop up(SeconPage.feature:7)

我错过了什么

Answer 1

（（JavascriptExecutor）驱动程序） .executeScript（“window.onbeforeunload=function（e）{}；”

Answer 2

如果警报确实存在，那么：

if(driver.switchTo().alert() != null)
{
    Alert alert = driver.switchTo().alert();
    alert.dismiss(); 
}

如果您必须等待它出现：

try {
    WebDriverWait wait = new WebDriverWait(driver, 8);
    wait.until(ExpectedConditions.alertIsPresent());
    Alert alert = driver.switchTo().alert();
    alert.accept();
} catch (Exception e) {
    //handle the exception
}

Answer 3

尝试以下内容，并让我知道它是否适用于您：

@When("^I am on second page I click on close button in pop up$")
public void i_am_on_second_page_I_click_on_close_button_in_pop_up() throws Throwable {
    driver.findElement(By.xpath("//*@id='ngdialog2']/descendant::div[@class='dialog-body']/descendant::div[@class='promo-popup-close']")).click();
    driver.switchTo().activeElement();
