如何使用Java在WebDriver中获取按钮的标题/文本

Question

I have the following HTML code for "Save" button:

<input type="submit" onclick="return confirm('Sure to change global settings?')" value="Save" name="submit">

I want to retrieve the caption of button. I used the following code to do that:

String actualButtonCaption = driver.findElement(By.xpath("//input[@value='Save']")).getText();

I also used the absolute xpath as below:

String actualButtonCaption = driver.findElement(By.xpath("//html/body/form/div[3]/div[2]/input")).getText();

But unfortunately, no text was retrieved. Blank/empty text was found. Can anybody help me?

Answer 1

getAttribute method could be used to retrieve the attribute values.

In this case following would return the caption:

driver.findElement(By.XPath("//input[@name='submit']")).getAttribute("value");

Answer 2

try associating an ID with input and then find element by ID. If text comes out, then there is a problem with xpath, you can analyze the exact run time xpath by using plugin of Firefox.

Answer 3

这应该工作-

String actualButtonCaption = driver.findElement(By.name("Submit")).getAttribute("value");

Answer 4

I have got the solution by using JavaScript. The code is as below:

WebDriver driver = new FirefoxDriver();
JavascriptExecutor jse = (JavascriptExecutor) driver;
String ss = (String)jse.executeScript("var x=document.getElementsByName('submit')[0].value; return x");
System.out.println("Caption of Save button: " + ss);

It works fine. The caption of button is printed as "Save"
