WebElement

class selenium_driverless.types.webelement.WebElement(target, frame_id, isolated_exec_id, obj_id=None, node_id=None, backend_node_id=None, loop=None, class_name=None, context_id=None, is_iframe=False)

Represents a DOM element.

Generally, all interesting operations that interact with a document 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 the element is still attached to the DOM. If this test fails, then a StaleElementReferenceException is thrown, and all future calls to this instance will fail.

property obj_id: str

async returns the Runtime.RemoteObjectId for the element

property context_id

async the Runtime.ExecutionContextId

property node_id

async the DOM.NodeId

property content_document

async gets the document of the iframe

property document_url

async gets the url if the element is an iframe, else returns None

async the DOM.BackendNodeId

property class_name

the ClassName of the element (if available)

async find_element(by, value, idx=0, timeout=None)

find an element in the current target

Parameters:

• by (str) – one of the locators at By

• value (str) – the actual query to find the element by

• timeout (Optional[int]) – how long to wait for the element to exist

• idx (int) – might be removed

async find_elements(by='id', value=None)

find multiple elements in the current target

Parameters:

• by (str) – one of the locators at By

• value (Optional[str]) – the actual query to find the elements by

async get_listeners(depth=3)

gets all listeners on the element. see DOMDebugger.getEventListeners

Parameters:

depth (int) – maximum depth (nested elements) to find listeners for

property source

async the OuterHtml of the element

async set_source(value)

sets the OuterHTML of the element

Parameters:

value (str) – the str to set the outerHtml to

async get_property(name)

Gets the given property of the element.

Parameters:

name (str) – the name of the property to get

Return type:

str

Note

this gets the JavaScript property (elem[name]), and not HTML property

property tag_name: str

This element’s tagName property.

property text: str

async The text of the element. (elem.textContent)

property value: str

async The value of the element. (elem.value)

async clear()

Clears the text if it’s a text entry element. (elem.value = "")

Return type:

None

async remove()

remove the element from the page//dom//html

async highlight(highlight=True)

highlight the element

Parameters:

highlight – whether to disable or enable highlight

Note

highlight automatically fades on any user-interaction, you might use a for-loop

async focus()

focuses the element (Dom.focus)

async is_clickable(listener_depth=3)

returns True if the element type is one of “a”, “button”, “command”, “details”, “input”, “select”, “textarea”, “video”, “map” else wise checks for “click”, “mousedown” or “mouseup” event listeners on the element

Parameters:

listener_depth – the depth (nested elements) to get event-listeners for

async click(timeout=None, visible_timeout=30, spread_a=1, spread_b=1, bias_a=0.5, bias_b=0.5, border=0.05, scroll_to=True, move_to=True, ensure_clickable=False)

Clicks the element.

Parameters:

• timeout (Optional[float]) – the time in seconds to take for clicking on the element

• visible_timeout (float) – the time in seconds to wait for being able to compute the elements box model

• spread_a (float) – spread over a

• spread_b (float) – spread over b

• bias_a (float) – bias over a (0-1)

• bias_b (float) – bias over b (0-1)

• border (float) – minimum border towards element edges (relative to element => 1). Random generated points outside that border get re-generated.

• scroll_to – whether to scroll to the element

• move_to (bool) – whether to move the mouse to the element

• ensure_clickable (Union[bool, int]) – whether to ensure that the element is clickable. Not reliable in on every webpage

Return type:

None

Note

a spread of 1 is equivalent to 6 std. relative to the element. (=> 99.7 %)

async write(text, click_kwargs=None, click_on=True)

inserts literal text to the element

Warning

This method is generally detectable. You might consider using Elem.send_keys instead.

Parameters:

• text (str) – the text to send

• click_kwargs – arguments to pass for Elem.send_keys

• click_on (bool) – whether to click on the element before inserting the text

async set_file(path)

sets the file on the current element (has to accept files)

Parameters:

path (str) – the absolute path to the file

async set_files(paths)

sets files on the current element (has to accept files)

Parameters:

paths (List[str]) – the absolute paths to the files

async send_keys(text, click_kwargs=None, click_on=True)

send text & keys to the target

Parameters:

• text (str) – the text to send to the target

• click_kwargs (Optional[dict]) – arguments to pass for Elem.send_keys

• click_on (bool) – whether to click on the element before sending the keys

Return type:

None

async mid_location(spread_a=1, spread_b=1, bias_a=0.5, bias_b=0.5, border=0.05)

returns random location in the element with probability close to the middle

Parameters:

• spread_a (float) – spread over a

• spread_b (float) – spread over b

• bias_a (float) – bias over a (0-1)

• bias_b (float) – bias over b (0-1)

• border (float) – minimum border towards element edges (relative to the element => 1). Random generated points outside that border get re-generated.

Return type:

List[int]

Note

a spread of 1 is equivalent to 6 std. relative to the element. (=> 99.7 %)

async submit()

Submits a form.

Warning

the current implementation likely is detectable. It’s recommended to use click instead if possible
