However, with effects, the next line of code can be run even though the effect is not finished. This can create errors. To prevent this, you can use Callback function Chaining function Counter function Stop function $(document).ready(function() { // Some code. }); The above code is used to.. Both A and B Make sure no code is executed till the entire page is fully loaded Make sure no code is executed till the DOM is fully loaded Neither A nor B How do you fetch the first span on the page, which has the class ‘green’? $('span.green:first') $('span, .green, :first') $('first .green span') When referencing an HTML element preceded by a # (pound or hash), what javascript function is this equivalent to?
