如何使用 Selenium 和 Java 单击确认按钮

Question

I have an Acknowledge button and I want to click it. I have tried all the three methods listed below. But it is not working.

driver.findElement(By.cssSelector("input.btn.btn.primary")).submit();
driver.findElement(By.xpath("//*[@id='content']/div[2]/div/input")).click();
driver.findElement(By.xpath("//*[@value='I Acknowledge' ")).click();

This is the HTML Of the page:

<input class="btn btn-primary" type="button" value="I Acknowledge">

Answer 1

Try with this css locator:

input[class='btn btn-primary'][value='I Acknowledge']

Answer 2

To click on the I Acknowledge element you have to induce WebDriverWait for the elementToBeClickable() and you can use either of the following Locator Strategies :

• cssSelector :

   new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("input.btn.btn-primary[value='I Acknowledge']"))).click();

• xpath :

   new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@class='btn btn-primary' and @value='I Acknowledge']"))).click();
