getElementByID value

[Michael Hill]

I have this tag:

<span id="member_id"></span>

and I want to change the value to "Member"

why can't I do:

document.getElementByID("member_id").value = "Member";

Any help is appreciated.

or it is:

document.getElementByID("member_id").innerHTML = "Member";

There is no value property to a span element.
I assume you want the text "Member" displayed in that span.

var e = document.getElementById("member_id");
var oTextNode = document.createTextNode("Member");
var oReplaceNode = e.childNodes(0);
oReplaceNode.replaceNode(oTextNode);

You could also use innerHTML, but I have heard it isn't cross-browser
enough. It would be

document.getElementById("member_id").innerHTML = "Member";

It's getElementById(), not getElementByID(), so it would be:

document.getElementById("member_id").innerHTML

But:

document.getElementById("member_id").appendChild(d ocument.createTextNode("Member"));

is more standards compliant. Please note that the line above is
only required when initially appending text to the empty span.
Once the text node exists, you only need to change it's value. If
you're certain that the span will always only contain a text
node, you could use something like:

if (document.getElementById("member_id").firstChild == null) {

document.getElementById("member_id").appendChild(d ocument.createTextNode("Member"));

} else {
document.getElementById("member_id").firstChild.no deValue =
"Something Else";
}
