jQuery Functions

Question

What is the use of writing a jQuery function like so...

$(function myFunction() {
    ...
});

What i mean is why wrap the function in $

Answer 1

I think that you mean like this:

$(function() {
  ...
});

This is shorthand for:

$(document).ready(function() {
  ...
});

What it does is registering a handler for the ready event, so the code in the function will be run as soon as the document has loaded.

Answer 2

It's a shortcut for

$(document).ready(function myFunction() {
    ...
});
