What does arguments[0] and arguments[1] mean when using executeScript() method from JavascriptExecutor inter

Answer 1

For executeScript API: executeScript(script/function, arg1, arg2, arg3, ...)

The first argument is a javascript snippet or a javascript function, if it's a javascript snippet, it will be wrapper into an javascript function inside executeScript.

The next arguments are the arguments for the javascript function represents the first argument.

arguments is javascript function build-in feature. you can use it to get real passed-in arguments when call function. Please see below example:

test('tom', 12, 'male', '175cm') // call function: test

function test(name, age) {
  console.log(name); // tom
  console.log(age);  // 12
  console.log(arguments); // ['tom', 12, 'male', '175cm']
  console.log(arguments[0]); // equal to argument: name, so print tom
  console.log(arguments[1]); // equal to argument: age, so print 12
  console.log(arguments[2]); // male
  console.log(arguments[3]); // 175cm
}
