#attribute(name) ⇒ String? Also known as: []

This method attempts to provide the most likely desired current value for the attribute of the element, even when that desired value is actually a JavaScript property. It is implemented with a custom JavaScript atom. To obtain the exact value of the attribute or property, use #dom_attribute or #property methods respectively.

More exactly, this method will return the value of the property with the given name, if it exists. If it does not, then the value of the attribute with the given name is returned. If neither exists, null is returned.

The “style” attribute is converted as best can be to a text representation with a trailing semicolon.

The following are deemed to be “boolean” attributes, and will return either “true” or “false”:

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:

When the value of “class” is requested, the “className” property is returned. When the value of “readonly” is requested, the “readOnly” property is returned.

Parameters:

  • name (String) —

    attribute name

Returns:

  • (String, nil) —

    attribute value

end

#clear ⇒ Object

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.

Note that the events fired by this event may not be as you’d expect. In particular, we don’t fire any keyboard or mouse events. If you want to ensure keyboard events are fired, consider using #send_keys with the backspace key. To ensure you get a change event, consider following with a call to #send_keys with the tab key.

def clear
  bridge.clear_element @id
end

#click ⇒ Object

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 raise a StaleElementReferenceError unless you know that 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.

Equivalent to:

driver.action.click(element)

Examples:

Click on a button


driver.find_element(tag_name: "button").click

Raises:

  • (StaleElementReferenceError) —

    if the element no longer exists as defined

#css_value(prop) ⇒ Object Also known as: style

Get the value of the given CSS property

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.
