Question

What is the difference between these two functions?

1:

$(document).ready(function myfunc() {
   function dosomething() {
      // do something
   }
});

2:

<script language="javascript">
function dosomething() {
   // do something
}
</script>

Answer 1

The $(document).ready() function executes when the DOM has finished loading. See http://api.jquery.com/ready/

Whereas the function is not executed until called. If you were to have a call to that function, it would happen as it is loading and not wait for any external event to complete as in the former. Like:

<script language="javascript">
dosomething();
function dosomething(){
// do something
}
</script>
