Can you have multiple $(document).ready(function(){ … }); sections?

May be this question is little bit funny.

I just want to know that can we use $(document).ready()more then one time on a page

If yes then what is the pros and cons for that?

Answer 1

you can use it more than once. In fact, if you don’t care at all about
keeping your code small, you could litter your javascript file with
them.

$(document).ready(function() {
      // some code here
    });
    $(document).ready(function() {
      // other code here
    });

It’s great to be able to group your functions within a file or even
across multiple files, and jQuery's flexible $(document).ready()
function allows you to do that, pain free.

Try this out:

$(document).ready(function() {
    alert('1!');
});

$(document).ready(function() {
    alert('2!');
});

$(document).ready(function() {
    alert('3!');
});

above code is the same as below

$(document).ready(function() {
    alert('1!');
    alert('2!');
    alert('3!');
});
