I am trying dynamically add children DIV under a DIV with ID="prnt". Addition of nodes work fine no problem. However strange enough when it comes to deleted nodes its only deleting the even numbered nodes including 0. Why is this, I could be something stupid but it seem more like a bug. I could be very wrong.
Please help Thank you in advance.
<script type="text/javascript">
function displayNodes()
{
var prnt = document.getElementById("prnt");
var chlds = prnt.childNodes;
var cont = document.getElementById("content");
for(i = 0; i < chlds.length; i++)
{
if(chlds[i].nodeType == 1)
{
cont.innerHTML +="<br />";
cont.innerHTML +="Node # " + (i+1);
cont.innerHTML +="<br />";
cont.innerHTML +=chlds[i].nodeName;
cont.innerHTML +="<br />";
}
}
}
function deleteENodes()
{
var prnt = document.getElementById("prnt");
var chlds = prnt.childNodes;
for(i = 0; i < chlds.length; i++)
{
if(!(chlds[i].nodeType == 3))
{
prnt.removeChild(chlds[i]);
}
}
}
function AddENodes()
{
var prnt = document.getElementById("prnt");
//Only even nodes are deletable PROBLEM
for(i = 0; i < 10; i++)
{
var newDIV = document.createElement('div');
newDIV.setAttribute("id", "c"+(i));
var text = document.createTextNode("New Inserted Child "+(i));
newDIV.appendChild(text);
prnt.appendChild(newDIV);
}
}
</script>
