A Function to Get a Parent DOM Node
The following JavaScript function obtains a reference to a parent node.
function getParent (elem, parName){
var par = elem;
do {
par = par.parentNode;
}
while (par.nodeName != parName)
return par;
}
It requires 2 parameters - a reference to a DOM element, and the name of a parent element we need to get a reference to.
