Interface WebElement

All Superinterfaces:
SearchContext

public interface WebElement
extends SearchContext

Represents an HTML element. Generally, all interesting operations to do with interacting with a page will be performed through this interface.

All method calls will do a freshness check to ensure that the element reference is still valid. This essentially determines whether or not the element is still attached to the DOM. If this test fails, then an StaleElementReferenceException is thrown, and all future calls to this instance will fail.

Method Detail

click

void click()
Click this element. If this causes a new page to load, this method will attempt to block until the page has loaded. At this point, you should discard all references to this element and any further operations performed on this element will throw a StaleElementReferenceException unless you know the element and the page will still be present. If click() causes a new page to be loaded via an event or is done by sending a native event then the method will *not* wait for it to be loaded and the caller should verify that a new page has been loaded.

There are some preconditions for an element to be clicked. The element must be visible and it must have a height and width greater then 0.

Throws:
StaleElementReferenceException - If the element no longer exists as initially defined

submit

void submit()
If this current element is a form, or an element within a form, then this will be submitted to the remote server. If this causes the current page to change, then this method will block until the new page is loaded.

Throws:
NoSuchElementException - If the given element is not within a form

sendKeys

void sendKeys(java.lang.CharSequence... keysToSend)
Use this method to simulate typing into an element, which may set its value.


clear

void clear()
If this element is a text entry element, this will clear the value. Has no effect on other elements. Text entry elements are INPUT and TEXTAREA elements.


getTagName

java.lang.String getTagName()
Get the tag name of this element. Not the value of the name attribute: will return "input" for the element <input name="foo" />.

Returns:
The tag name of this element.

getAttribute

java.lang.String getAttribute(java.lang.String name)
Get the value of a the given attribute of the element. Will return the current value, even if this has been modified after the page has been loaded. More exactly, this method will return the value of the given attribute, unless that attribute is not present, in which case the value of the property with the same name is returned. If neither value is set, null is returned. The "style" attribute is converted as best can be to a text representation with a trailing semi-colon. The following are deemed to be "boolean" attributes, and will return either "true" or null: async, autofocus, autoplay, checked, compact, complete, controls, declare, defaultchecked, defaultselected, defer, disabled, draggable, ended, formnovalidate, hidden, indeterminate, iscontenteditable, ismap, itemscope, loop, multiple, muted, nohref, noresize, noshade, novalidate, nowrap, open, paused, pubdate, readonly, required, reversed, scoped, seamless, seeking, selected, spellcheck, truespeed, willvalidate Finally, the following commonly mis-capitalized attribute/property names are evaluated as expected:

Parameters:
name - The name of the attribute.
Returns:
The attribute's current value or null if the value is not set.

isSelected

boolean isSelected()
Determine whether or not this element is selected or not. This operation only applies to input elements such as checkboxes, options in a select and radio buttons.

Returns:
True if the element is currently selected or checked, false otherwise.

isEnabled

boolean isEnabled()
Is the element currently enabled or not? This will generally return true for everything but disabled input elements.

Returns:
True if the element is enabled, false otherwise.

getText

java.lang.String getText()
Get the visible (i.e. not hidden by CSS) innerText of this element, including sub-elements, without any leading or trailing whitespace.

Returns:
The innerText of this element.

findElements

java.util.List<WebElement> findElements(By by)
Find all elements within the current context using the given mechanism. When using xpath be aware that webdriver follows standard conventions: a search prefixed with "//" will search the entire document, not just the children of this current node. Use ".//" to limit your search to the children of this WebElement. This method is affected by the 'implicit wait' times in force at the time of execution. When implicitly waiting, this method will return as soon as there are more than 0 items in the found collection, or will return an empty list if the timeout is reached.

Specified by:
findElements in interface SearchContext
Parameters:
by - The locating mechanism to use
Returns:
A list of all WebElements, or an empty list if nothing matches.
See Also:
By, WebDriver.Timeouts

findElement

WebElement findElement(By by)
Find the first WebElement using the given method. See the note in findElement(By) about finding via XPath. This method is affected by the 'implicit wait' times in force at the time of execution. The findElement(..) invocation will return a matching row, or try again repeatedly until the configured timeout is reached. findElement should not be used to look for non-present elements, use findElements(By) and assert zero length response instead.

Specified by:
findElement in interface SearchContext
Parameters:
by - The locating mechanism
Returns:
The first matching element on the current context.
Throws:
NoSuchElementException - If no matching elements are found
See Also:
By, WebDriver.Timeouts

isDisplayed

boolean isDisplayed()
Is this element displayed or not? This method avoids the problem of having to parse an element's "style" attribute.

Returns:
Whether or not the element is displayed

getLocation

Point getLocation()
Where on the page is the top left-hand corner of the rendered element?

Returns:
A point, containing the location of the top left-hand corner of the element

getSize

Dimension getSize()
What is the width and height of the rendered element?

Returns:
The size of the element on the page.

getCssValue

java.lang.String getCssValue(java.lang.String propertyName)
Get the value of a given CSS property. This is probably not going to return what you expect it to unless you've already had a look at the element using something like firebug. Seriously, even then you'll be lucky for this to work cross-browser. Color values should be returned as hex strings, so, for example if the "background-color" property is set as "green" in the HTML source, the returned value will be "#008000". Note that shorthand CSS properties (e.g. background, font, border, border-top, margin, margin-top, padding, padding-top, list-style, outline, pause, cue) are not returned, in accordance with the DOM CSS2 specification - you should directly access the longhand properties (e.g. background-color) to access the desired values.

Returns:
The current, computed value of the property.
