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

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, nil 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 “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:

class, readonly

def clear
  bridge.clearElement @id
end

#clickObject

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
