js childnodes gets all the child elements, and we're actually getting the first-level child element.
function getChildren(obj){
var objChild = [] ;
var objs = obj.getElementsByTagName('*');
for(var i=0,j=objs.length; i<j;++i){
if(objs[i].nodeType != 1){alert(objs[i].nodeType);
continue ;
}
var temp = objs[i].parentNode;
if(temp.nodeType == 1){
if(temp == obj){
objChild[objChild.length] = objs[i] ;
}
}else if(temp.parentNode == obj){
objChild[objChild.length] = objs[i] ;
}
}
return objChild ;
}
