JS prohibits selecting text, copying text code
IE has onselectstart this method by setting this method to prevent element text from being selected. Firefox does not have this method, but it can be done through a CSS tutorial or a workaround:
if (typeof (Element.onselectstart)!= "undefined") {
IE prohibits elements from being selected
Element.onselectstart = new Function ("return false");
} else {
Workarounds to prevent elements from being selected under Firefox
Element.onmousedown = new Function ("return false");
Element.onmouseup = new Function ("return true");
}

or use Css:div {
-moz-user-select:none;
-webkit-user-select:none;
User-select:none;
}

if (document.all)
{
obj.onselectstart= function () {return false;}; For IE

obj.onmousedown= function () {return false;};
obj.onmouseup= function () {return true;};
