Move table rows up and down - Jquery/Javascript

Question

Can anyone please tell me how to move table rows up and down through jQuery/Javascript.

I have a table and for each row a radio button is there in the first td. On c

Answer 1

First get the selected row:

var radio;
// assuming there's only one form in your page, replace 0 with whatever it is
// and inputs have name 'radioGroupName'
for (var i in document.forms[0].radioGroupName) {
    if (documents.forms[0].radioGroupName[i].checked) {
        radio = documents.forms[0].radioGroupName[i].parentNode.parentNode;
        break;
    }
}

To shift up:

var prev = radio.previousSibling;
var par = radio.parentNode;
if (prev) {
    par.removeChild(radio);
    par.insertBefore(radio, prev);
}

To shift down:

var next = radio.nextSibling;
var par = radio.parentNode;
par.removeChild(radio);
if (next.nextSibling)
    par.insertBefore(radio, next.nextSibling);
else
    par.appendChild(radio);
