<script><br />
function sDrag(id) {<br />
var id = id || 'sara';<br />
var m = document.getElementById(id);<br />
var flag = false;<br />
var sX = sY = 0;<br />
m.onmousedown = function(e) {<br />
if (e.button == 0) {<br />
flag = true;<br />
}<br />
sX = e.clientX - m.offsetLeft;<br />
sY = e.clientY - m.offsetTop;<br />
return false<br />
};<br />
document.onmousemove = function(e) {<br />
if (flag == true) {<br />
var x = e.clientX - sX;<br />
var y = e.clientY - sY;<br />
m.style.marginLeft = m.style.marginTop = 0;<br />
m.style.left = x + 'px';<br />
m.style.top = y + 'px';<br />
}<br />
return false;<br />
};<br />
document.onmouseup = function() {<br />
flag = false;<br />
return false;<br />
};<br />
}<br />
$(function() {<br />
sDrag('sara_org');<br />
})<br />
