waitForExist

Wait for an element for the provided amount of milliseconds to be present within the DOM. Returns true if the selector matches at least one element that exists in the DOM, otherwise throws an error. If the reverse flag is true, the command will instead return true if the selector does not match any elements.

info

As opposed to other element commands WebdriverIO will not wait for the element to exist to execute this command.

Usage

$(selector).waitForExist({ timeout, reverse, timeoutMsg, interval })

Parameters

Name	Type	Details
options optional	WaitForOptions	waitForEnabled options (optional)
options.timeout optional	Number	time in ms (default set based on waitforTimeout config value)
options.reverse optional	Boolean	if true it waits for the opposite (default: false)
options.timeoutMsg optional	String	if exists it overrides the default error message
options.interval optional	Number	interval between checks (default: waitforInterval)
