$
The $
command is a short and handy way in order to fetch a single element on the page.
As opposed to the $
attached to the browser object
this command queries an element based on a root element.
You can also pass in an object as selector where the object contains a property element-6066-11e4-a52e-4f735466cecf
with the value of a reference to an element. The command will then transform the reference to an extended WebdriverIO element.
Note: chaining $
and $$
commands only make sense when you use multiple selector strategies. You will otherwise
make unnecessary requests that slow down the test (e.g. $('body').$('div')
will trigger two request whereas
$('body div')
does literally the same with just one request)
You can chain $
or $$
together without wrapping individual commands into await
in order
to walk down the DOM tree, e.g.:
const imageSrc = await $$('div')[1].nextElement().$$('img')[2].getAttribute('src')
WebdriverIO seamlessly traverses shadow roots when using the $
or $$
commands, regardless of the nesting level or
shadow root mode, for example:
await browser.url('https://ionicframework.com/docs/usage/v8/datetime/basic/demo.html?ionic:mode=md')
await browser.$('button[aria-label="Sunday, August 4"]').click()
await browser.$('.aux-input').getValue()
