How to remove mynavbar and append to main_table as the first element

<div id="mynavbar" > <div>Some content</div>  </div>

<div id="main_table"> </div>

}
</script>

$("#mynavbar").prependTo("#main_table");

$('#mynavbar').prependTo('#main_table').remove();

$('#main_table').prepend ( $('#mynavbar').html() );

$('#mynavbar').remove ();

Here's a non-jQuery answer for some variety.

var main = document.getElementById("main_table");
var secondary = document.getElementById("mynavbar");
if(main.firstChild)
{
    main.insertBefore(secondary, main.firstChild);
    console.log("first");
}else
{
    main.appendChild(secondary);
    console.log("last");   
}

EDIT: I'm amazed that there's 5 nearly identical answers. Yikes.

for remove you can simply use...

$("#mynavbar").remove();

but once it will removed, it will not be there in your html..you should try something like this...

  var mynavbarHTML= $("#mynavbar").html();
   $("#mynavbar").remove();
  $("#main_table").prepend(mynavbarHTML);
