waitForSelector(selector[, options])

Open source

waitForSelector(selector[, options])

Note
Use web assertions that assert visibility or a locator-based locator.waitFor([options]) instead.

Returns when element specified by selector satisfies state option.

Parameter	Type	Default	Description
selector	string	`''`	A selector to search for an element. If there are multiple elements satisfying the selector, the first will be used.
options	object	`null`
options.state	string	`visible`	Can be either `attached`, `detached`, `visible`, `hidden` See Element states for more details.
options.strict	boolean	`false`	When `true`, the call requires selector to resolve to a single element. If given selector resolves to more than one element, the call throws an exception.
options.timeout	number	`30000`	Maximum time in milliseconds. Pass `0` to disable the timeout. Default is overridden by the `setDefaultTimeout` option on BrowserContext or Page.

Element states

Element states can be either:

'attached' - wait for element to be present in DOM.
'detached' - wait for element to not be present in DOM.
'visible' - wait for element to have non-empty bounding box and no visibility:hidden.
'hidden' - wait for element to be either detached from DOM, or have an empty bounding box or visibility:hidden.

Returns

Type	Description
`Promise<ElementHandle \| null>`	A Promise that fulfills with the ElementHandle when a matching element is found, or `null` if the element is not found.

        browser: {
          type: 'chromium',
        },
      },
    },
  },
};

export default async function () {
  const page = await browser.newPage();
  await page.goto('https://test.k6.io/browser.php');
  await page.waitForSelector('#text1');
