I recently implemented the "How to handle hidden web elements using the JavaScript executor method".
However, I am still unclear about how the method works.
public static void selectDateByJS(WebDriver driver, WebElement element, String dateVal) {
JavascriptExecutor js = ((JavascriptExecutor) driver);
js.executeScript("arguments[0].setAttribute('value', '" + dateVal + "');", element);
}
Can someone explain what the argument[0] represents and its significance?
arguments[x] allows you to refer to the parameters that are passed into a function or method.
Since arguments is treated as an object, you can retrieve the values using their respective keys.
This technique can be particularly useful in situations where there are no predefined parameters but arguments are still being passed, such as when dealing with functions that accept an infinite number of arguments.
function myFunction() {
console.log('all', arguments)
console.log('first', arguments[0])
console.log('second', arguments[1])
console.log('third', arguments[2])
}
