单击使用Webdriver和javascript的按钮

Question

I have seen many questions and solutions for clicking on a button using webdriver. I have tried various solutions and none seem to resolve my issue. Please help. Here is my HTML snippet.

<b>
<input name="submit" onclick="javascript:document.getElementById('submitClicked').value='Next';return true;" type="submit" tabindex="2" class="-opa-btn-primary nextButton" value="Next" alt="'Next'" id="submitNext">
</b>

I need to click on this "Next" button.

I tried:

JavascriptExecutor executor = (JavascriptExecutor)driver;
executor.executeScript("return document.getElementById('submitClicked').value='Next';return true;");

This didn't work, it gives exception saying document.getElementBy ID return null.

Next, I tried:

if(driver.findElement(By.Id("submitNext").isEnabled())
    driver.findElement(By.Id("submitNext").click();

This also didn't work.

Answer 1

Step 1:

With the given Info We can use ID for the submit button(submitNext)

Step 2:

Write a prototype for Visible Function

public static boolean isVisibleByID(String id)

{

try

{

  driver.findElement(By.id(id)).isEnabled();
  return true;

}

catch(Exception e)

{

    e.printStackTrace();
    return false;

}

}

Step 3:

if(isVisibleByID("submitNext")) driver.findElement(By.Id("submitNext").click();
