Solution 1:

You can insert an element before an other by calling the insertBefore() function on the parent element.

For example if you want to insert div2 before div1, you can do this:

parent.insertBefore(div2, div1);

The following code inserts div1 before div4:

var div1 = document.getElementById('div1');
var div4 = document.getElementById('div4');

var parent = div1.parentNode;

parent.insertBefore(div1, div4);

After executing the the order of the divs is 2, 3, 1, 4.

Solution 2:

DEMO

This should be pretty easy to understand:

HTML:

<div id="container">
    <div id="div1">1</div>
    <div id="div2">2</div>
    <div id="div3">3</div>
    <div id="div4">4</div>
</div>

Javascript:

var container = document.getElementById('container'), 
    divs = container.getElementsByTagName('div'),
    tmpdiv = document.createElement('div'),
    order = [2, 1, 3, 4];

for (var i = 0; i < order.length; i++) {
    tmpdiv.appendChild(  document.getElementById('div' + order[i])  );
}

container.parentNode.replaceChild(tmpdiv, container);

Solution 3:

• I'm grabbing the DIV with id container, using getElementById
• Getting the children of that DIV with .children()
• using outerHTML and building a new string swapping the 1st and 3rd elements
• setting the innerHTML to the string i just built

HTML

<divid="containter"><div>1</div><div>2</div><div>3</div><div>4</div></div>

JavaScript

var el = document.getElementById('containter'),
    divs = el.children,
    len = divs.length;

// swap 3 and 1var html = divs[1].outerHTML;
html += divs[2].outerHTML;
html += divs[0].outerHTML;
html += divs[4].outerHTML;

el.innerHTML = html;
