Hello:

Could someone tell me how I can programatically
(JScript/DHTML) change the value of a Label tag?

For example, this is the HTML code:

<FORM name="myForm">
<LABEL for="myformfield">LabelValue</LABEL>
....
</FORM>

What is the code necessary to change the "LabelValue"
variable?

Thank you for any assistance you can provide.

Well the easiest way would be to give it an id at creation time <lable
id="lblSurname" for="myformfield"> and then change its innerHTML/innerText
var oLabel = document.getElementById("lblSurname");
oLabel.innerText = "New Value";
//OR
oLabel.innerHTML = "<i>New Value<i>";
if you wish to use formatting.
If you don't have the id, just the identifier of the form field to which it
applies then you need to find it first:
function getLabelFromFormField(FieldId)
{
var oLabel = null;
var sFieldId = FieldId.toLowerCase();
var colLabels = document.getElementsByTagName("label");
for (var i = 0; i < colLabels.length; i++)
{
if (colLabels[i].htmlFor.toLowerCase() == sFieldId)
{
oLabel = colLabels[i];
break;
}
}
return oLabel;
}

I'm not sure if this needs name or id of the form element or will accept
either.
