Create Next button loop

[alehambre]

I am using DOM to view XML in an HTML form. I need some help constructing a loop to allow user to click "Next" button, to view next XML node. I am trying to use the variable "A" to control the array position. I want to create a loop that adds 1 to the value of A each time the button is clicked.
Please help me understand how to break after 1 is added to "A", and how to continue the loop each time the button is clicked.

PrintNode = xmldoc.childNodes[2].selectNodes('./Print');

var A = 0

function NextNode(){
for ( var A = 0; A < 100; A++)
{
document.getElementById("printid").value = PrintNode[A].childNodes[0].text
}
}


Sample XML:
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="Printlist.xsl"?>
<PrintList>
<Print>
<ID>001000</ID>
<PrintName>Spring Garden</PrintName>
<Season>spring</Season>
<PrintSize>5x9</PrintSize>
<file href="springgarden.jpg"/>
<Desc></Desc>
</Print>
</PrintList>

Try something like this instead of a loop:

var A = 0;

function NextNode(){
A++;
if (A < 100)
  {
  document.getElementById("printid").value = PrintNode[A].childNodes[0].text;
  }
}

Thanks for your help. I really appreciate it.

If you only want to display 1 record at a time, you shouldn't be using a loop.

Initialise "A" (which I'll rename to "recordNumber" to be a lot more descriptive) to 0, and then show the content of that record:

var recordNumber = 0;
var numberOfRecords = 100;

function showCurrentNode() {
	document.getElementById('printid').value = PrintNode[recordNumber].childNodes[0].text;
}

function gotoPrevNode() {
	if (recordNumber > 0) {
		recordNumber--;
		showCurrentNode();
	}
}

function gotoNextNode() {
	if (recordNumber < numberOfRecords-1) {
		recordNumber++;
		showCurrentNode();
	}
}

So now you simply call the gotoNextNode and gotoPrevNode functions from your links / buttons.

Hope this helps,

BillyRay,

Thanks, sorry I didn't get to reply sooner.

Yes, this did work. I resolved this part of the tool.
I can't tell you how thrilled I was.

Thanks again.
