var yourVar; // some  DOM instance
var newFirstElem; //element which should be first in yourVar

yourVar.insertBefore(newFirstElem, yourVar.firstChild);

THis will add as the first child. To add after just use normal append.

Edit:

Consider you have this in the beginning:

  <div class="blabla">
     <div class="ABCD">

     </div>
  </div>

And you want to add <ul class="abcd" id="abcd></ul> to div with class ABCD

$(".ABCD").append('<ul class="abcd" id="abcd></ul>')

You want to add to div with class blabla

$(".blabla").append('<ul class="abcd" id="abcd></ul>')

Consider you have already have this this

<div class="blabla">
         <div class="ABCD">
             <ul class="abcd" id="abcd></ul>
         </div>
      </div>

and now you want to add before the ul inside the div with class abcd

$(".abcd").prepend("<ul class="abcd" id="abcd></ul>");

jQuery makes it simpler. You can just use prepend function. This function allows you to insert whatever you like at the beginning. There are also the option of inserting at specific positions. You should take a look at:

insertAt

insertBefore

after

before

shahbaz faraz Over a year ago

there is a lots of html . and i have to use this in different pages so every page have different html

shahbaz faraz Over a year ago

if this is not possible to do this id this possible to do it in jquesry-ui.js? because i am getting value of ul from jquery . i want that i could add some javascript in it so it could start a div before ul and end after ul ajax.googleapis.com/ajax/libs/jqueryui/1/jquery-ui.min.js"

shahbaz faraz Over a year ago

if you meant to say before and after code ( code which we "will"put after and before using javascript ) then it is a simple div ( div starts before the ul and ends after ul as i said above )

if you have a html file like this

<html>
<body>
<ul id="1"></ul>
</body>

and you what this

<html>
<head></head>
<body>
    <div>
        <ul id="1"></ul>
    </div>
</body>

use this javascript

var x = document.getElementsByTagName("body")[0];
var b = document.getElementById("1");
var a = document.createElement("div");
x.appendChild(a);
a.appendChild(b);

<!doctype>
<html>
    <head>
        <title>Example - Javascript - Add element before/after</title>
        <script language="javascript">
        function mAddBegin()
        {
            var tNew = document.createElement('li');
            tNew.innerHTML = document.getElementById('value').value;

            var tList = document.getElementById('list');
            tList.insertBefore(tNew, tList.firstChild);
        }
        function mAddBefore()
        {
            var tNew = document.createElement('li');
            tNew.innerHTML = document.getElementById('value').value;

            var tList = document.getElementById('list');
            var tTea = document.getElementById('tea');
            tList.insertBefore(tNew, tTea);
        }
        function mAddAfter()
        {
            var tNew = document.createElement('li');
            tNew.innerHTML = document.getElementById('value').value;

            var tList = document.getElementById('list');
            var tTea = document.getElementById('tea');
            tList.insertBefore(tNew, tTea.nextSibling);
        }
        function mAddEnd()
        {
            var tNew = document.createElement('li');
            tNew.innerHTML = document.getElementById('value').value;

            var tList = document.getElementById('list');
            tList.appendChild(tNew);
        }
        </script>
    </head>
