I have this Javascript in a for loop:
renderAElements[i] = document.createElement ("a");
renderAElements[i].setAttribute("href", "#");
renderAElements[i].setAttribute("class", "expander");
renderAElements[i].appendChild(expand);
alert (renderAElements[i].nodeValue);
where expand is created as:
var expand = document.createTextNode("+");
The alert, which is meant to return the link text of each created element returns null. Why is this?

Reset to default 5Because you are trying to get the nodeValue of the Element node and not the Text node.
alert (renderAElements[i].firstChild.nodeValue);
It's because the a element contains another element and not a value. If you want to get the text out of the node you'll need to do either
renderAElements.childNodes[0].nodeValue
or
renderAElements.innerText
Check this out
<head>
<script type="text/javascript">
function GetTextNode () {
var textContainer = document.getElementById ("textContainer");
var textNode = textContainer.firstChild;
alert (textNode.data);
}
</script>
</head>
<body>
<div id="textContainer">This is a simple text in the container.</div>
<button onclick="GetTextNode ()">Get the contents of the container</button>
</body>
try this alert (renderAElements[i].firstChild.nodeValue);
