Run Function After Delay

$(document).ready(function() {

  // place this within dom ready function
  function showpanel() {     
    $(".navigation").hide();
    $(".page").children(".panel").fadeIn(1000);
 }

 // use setTimeout() to execute
 setTimeout(showpanel, 1000)

});

I searched and found the solution in the following URL is better.

It worth to try.

It adds your given function to the queue of functions to be executed on the matched element which is currently this.

 $(this).delay(1000).queue(function() {

     // your Code | Function here
     
     $(this).dequeue();
  
  });

and then execute the next function on the queue for the matched element(s) which is currently this again.

-- EDIT [ POSSIBLE EXPLANATION FOR THE DEQUEUE COMMAND ]

Take a look at the command

We command the jQuery engine to add a function in internal queue and then after a specific amount of time we command it to call that function, BUT so far we never told it to dequeue it from engine. Right?! And then after every thing is done we are dequeue it from jQuery engine manually. I hope the explanation could help.
