How to get caption/text of button in WebDriver using Java
提问by Ripon Al Wasim
I have the following HTML code for "Save" button:
我有以下用于“保存”按钮的 HTML 代码：
<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:
我想检索按钮的标题。我使用以下代码来做到这一点：
String actualButtonCaption = driver.findElement(By.xpath("//input[@value='Save']")).getText();
I also used the absolute xpath as below:
我还使用了绝对 xpath，如下所示：
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?
但不幸的是，没有检索到任何文本。发现空白/空文本。有谁能够帮我？

getAttributemethod could be used to retrieve the attribute values.
getAttribute方法可用于检索属性值。
In this case following would return the caption:
在这种情况下，以下将返回标题：
driver.findElement(By.XPath("//input[@name='submit']")).getAttribute("value");
driver.findElement(By.XPath("//input[@name='submit']")).getAttribute("value");

This should work -
这应该有效 -
String actualButtonCaption = driver.findElement(By.name("Submit")).getAttribute("value");

try associating an IDwith 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.
尝试将 anID与输入相关联，然后按 ID 查找元素。如果出现文本，则xpath有问题，您可以使用Firefox的插件分析确切的运行时间xpath。

I have got the solution by using JavaScript. The code is as below:
我通过使用 JavaScript 得到了解决方案。代码如下：
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"
它工作正常。按钮的标题打印为“保存”
