Try <code>element.getAttribute("value")</code>

The <code>text</code> property is for text within the tags of an element. For input elements, the displayed text is not wrapped by the <code>&lt;input&gt;</code> tag, instead it's inside the <code>value</code> attribute.

Note: Case matters. If you specify "Value", you'll get a 'null' value back. This is true for C# at least.

This is kind of hacky, but it works.

I used <code>JavascriptExecutor</code> and added a <code>div</code> to the HTML, and changed the text in the <code>div</code> to <code>$('#prettyTime').val()</code> I then used Selenium to retrieve the <code>div</code> and grab its value. After testing the correctness of the value, I removed the div that was just created.

If the input value gets populated by a script that has some latency involved (e.g. AJAX call) then you need to wait until the input has been populated.
E.g.

<pre><code>var w = new WebDriverWait(WebBrowser, TimeSpan.FromSeconds(10));
 w.Until((d) =&gt; {
 // Wait until the input has a value...

 var elements = d.FindElements(By.Name(name));

 var ele = elements.SingleOrDefault();

 if (ele != null)
 {
 // Found a single element

 if (ele.GetAttribute("value") != "")
 {
 // We have a value now
 return true;
 }
 }

 return false;
 });

 var e = WebBrowser.Current.FindElement(By.Name(name));

 if (e.GetAttribute("value") != value)
 {
 Assert.Fail("Result contains a field named '{0}', but its value is '{1}', not '{2}' as expected", name, e.GetAttribute("value"), value);
 }
</code></pre>

With selenium 2, 

i usually write it like that :

<pre><code>WebElement element = driver.findElement(By.id("input_name"));
String elementval = element.getAttribute("value");
</code></pre>

OR

<pre><code>String elementval = driver.findElement(By.id("input_name")).getAttribute("value");
</code></pre>

}|code-block|syntax|javascript|534757|但是如您所见，您的元素必须有一个id属性，而且页面上还必须有一个jquery。|offset|length|style|CODE|534758|entityMap^0|0|0|G|2|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@$I|R|J|S|K|L]]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

As was mentioned before, you could do something like that

<pre><code>public String getVal(WebElement webElement) {
 JavascriptExecutor e = (JavascriptExecutor) driver;
 return (String) e.executeScript(String.format("return $('#%s').val();", webElement.getAttribute("id")));
}
</code></pre>

But as you can see, your element must have an <code>id</code> attribute, and also, jquery on your page.

blocks|key|534767|text|你可以这样做：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|534768|webelement+time=driver.findElement(By.id("input_name")).getAttribute("value");|code-block|syntax|javascript|534769|这将为您提供显示在网页上的时间。|534770|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

You can do like this :

<pre><code>webelement time=driver.findElement(By.id("input_name")).getAttribute("value");
</code></pre>

this will give you the time displaying on the webpage.

Following @ragzzy 's answer I use

<pre><code> public static string Value(this IWebElement element, IJavaScriptExecutor javaScriptExecutor)
 {

 try
 {
 string value = javaScriptExecutor.ExecuteScript("return arguments[0].value", element) as string;
 return value;

It works quite well and does not alter the DOM

Eventhough if you don't see the "value" attribute in html dom, you will get the field value displayed on the GUI.

In the HTML of a webapp there is the following code

<pre><code>&lt;input type="text" name="prettyTime" id="prettyTime" class="ui-state-disabled prettyTime" readonly="readonly"&gt;
</code></pre>

What is actually shown on the page is a string displaying the time.

In Selenium Web Driver, I have a <code>WebElement</code> object referring to the <code>&lt;input&gt;</code> using

<pre><code>WebElement timeStamp = waitForElement(By.id("prettyTime"));
</code></pre>

I want to get the value of the <code>WebElement</code>, or, in other words, what is printed on the page. I tried all the <code>WebElement</code> getters and nothing has been retrieving the actual value that the user sees. Any help? Thanks.
