session.executeScript<T>(script, args)

Inject a snippet of JavaScript into the page for execution in the context of the currently selected frame. The executed script is assumed to be synchronous and the result of evaluating the script is returned to the client.

PARAMETERS

script: string - JavaScript to execute in browser context
args: unknown[] - Arguments to sent to executed script

RETURNS

Promise<T>

EXAMPLES

const script = `
  const [name] = arguments;
  return `Hello from ${name}!`;
`;
const message = await session.executeScript(script, ['WebDriver']);
// message = 'Hello from WebDriver!'

const button = await session.findElement('css selector', '#red-button');
const script = `
   const [element] = arguments;
   return element.id;
`;
const id = await session.executeScript(script, [button]);
// id = 'red-button'

const script = `
   return document.querySelector('#red-button');
`;
const button = await session.executeScript(script);
const id = await button.getProperty('id');
// id = 'red-button'

WebDriver spec

session.executeAsyncScript<T>(script, args)

causes JavaScript to execute as an anonymous function. Unlike the Execute Script command, the result of the function is ignored. Instead an additional argument is provided as the final argument to the function. This is a function that, when called, returns its first argument as the response.

PARAMETERS

script: string - JavaScript to execute in browser context
args: unknown[] - Arguments to sent to executed script

RETURNS

Promise<T>

EXAMPLES

const script = `
  const [a, b, callback] = arguments;
  setTimeout(() => callback(a * b), 1000);
`;
const message = await session.executeAsyncScript(script, [5, 3]);
// message = 15

const button = await session.findElement('css selector', '#red-button');
const script = `
   const [element, callback] = arguments;
   callback(element.id);
`;
const id = await session.executeAsyncScript(script, [button]);
// id = 'red-button'

const script = `
   const [callback] = arguments;
   callback(document.querySelector('#red-button'));
`;
const button = await session.executeAsyncScript(script);
const id = await button.getProperty('id');
// id = 'red-button'
