添加取得子节点

function  testXML() ... {
        var pp=document.getElementById("pp");
        var p=pp.childNodes;
        for(i=0;i<p.length;i++)...{
                alert(p[i].innerHTML);
            }
            var node = document.createTextNode("6");
            pp.appendChild(node);
    }

< div  onclick ="testXML()" > klnknnjnj </ div >
     < div  id ="pp" >
         < div  id ="p" > 1 </ div >
         < div  id ="p" > 2 </ div >
         < div  id ="p" > 3 </ div >
         < div  id ="p" > 4 </ div >
         < div  id ="p" > 5 </ div >
     </ div >

 

得到子节点是xx.childNodes

 

添加子节点是xx.appendChild(node) ;
