WebElements can be found by searching from the
document root using a <code >webdriver.WebDriver</code> instance, or by searching
under another <code >webdriver.WebElement</code>:
<pre><code>
driver.get('http://www.google.com');
var searchForm = driver.findElement(By.tagName('form'));
var searchBox = searchForm.findElement(By.name('q'));
searchBox.sendKeys('webdriver');
</code></pre>
The WebElement is implemented as a promise for compatibility with the promise
API. It will always resolve itself when its internal state has been fully
resolved and commands may be issued against the element. This can be used to
catch errors when an element cannot be located on the page:
<pre><code>
driver.findElement(By.id('not-there')).then(function(element) {
alert('Found an element that was not expected to be there!');
}, function(error) {
alert('The element was not found, as expected');
});

If the element
cannot be found, a <code >bot.ErrorCode.NO_SUCH_ELEMENT</code> result will
be returned by the driver. Unlike other commands, this error cannot be
suppressed. In other words, scheduling a command to find an element doubles
as an assert that the element is present on the page. To test whether an
element is present on the page, use <code >#isElementPresent</code> instead.
<p>The search criteria for an element may be defined using one of the
factories in the <code class="type"><a href="namespace_webdriver_By.html">webdriver.By</a></code> namespace, or as a short-hand
<code class="type"><a href="namespace_webdriver_By.html#webdriver.By.Hash">webdriver.By.Hash</a></code> object. For example, the following two statements
are equivalent:
<code><pre>
var e1 = element.findElement(By.id('foo'));
var e2 = element.findElement({id:'foo'});
</pre></code>
<p>You may also provide a custom locator function, which takes as input
this WebDriver instance and returns a <code class="type"><a href="class_webdriver_WebElement.html">webdriver.WebElement</a></code>, or a
promise that will resolve to a WebElement. For example, to find the first
visible link on a page, you could write:
<code><pre>
var link = element.findElement(firstVisibleLink);
function firstVisibleLink(element) {
var links = element.findElements(By.tagName('a'));
return webdriver.promise.filter(links, function(link) {
return links.isDisplayed();
}).then(function(visibleLinks) {
return visibleLinks[0];
});
}

<p/>
Modifier keys (SHIFT, CONTROL, ALT, META) are stateful; once a modifier is
processed in the keysequence, that key state is toggled until one of the
following occurs:
<ul>
<li>The modifier key is encountered again in the sequence. At this point the
state of the key is toggled (along with the appropriate keyup/down events).
</li>
<li>The <code >webdriver.Key.NULL</code> key is encountered in the sequence. When
this key is encountered, all modifier keys current in the down state are
released (with accompanying keyup events). The NULL key can be used to
simulate common keyboard shortcuts:
<code><pre>
element.sendKeys("text was",
webdriver.Key.CONTROL, "a", webdriver.Key.NULL,
"now text is");
// Alternatively:
element.sendKeys("text was",
webdriver.Key.chord(webdriver.Key.CONTROL, "a"),
"now text is");
</pre></code></li>
<li>The end of the keysequence is encountered. When there are no more keys
to type, all depressed modifier keys are released (with accompanying keyup
events).
</li>
</ul>
<strong>Note:</strong> On browsers where native keyboard events are not yet
supported (e.g. Firefox on OS X), key events will be synthesized. Special
punctionation keys will be synthesized according to a standard QWERTY en-us
keyboard layout.</summary><div class="info"><table><tbody><tr><th>Parameters<tr><td><dl><dt>var_args: <code class="type">...<a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String">string</a></code><dd>The sequence of keys to
