Add content to existing div

[question.boy]

I have been trying to find an example of how-to add html text to an
exisiting div and have had little success.

The best I found so far was

var pTag = document.createElement("p");
pTag.innerHTML = noBlanks+" is a mandatory field.";
document.getElementById("FormErrors").appendChild(pTag);

However, I was hoping I could pass HTML code and not just text,
something more like

"New line added.<br />"

or anyother HTML Tag I may need to use.

Also, the code only seems to work in IE and not Firefox...?

Thank you for your help!

You can.

Ther error is somewhere else. This should work in FF; most browsers
support innerHTML, even though it's not officially standard.

Assuming your div has an id attribute called "div_id", you can do
this:

var div = document.getElementById('div_id');
div.innerHTML = "<p><b>Whatever</b> HTML that you may want.</p>";

Here is the function in question. It works fine in IE but nothing in
Firefox.

function validate_form(theForm) {
/*Validates the user submitted data to ensure that data has been
input and that it is valid
and posts an error message if there is an issue.*/
var frmOk = true; //initialize validation status variable
var errColor = 'ffff99'; //background color when there is an error
in validation

// Create an array of controls to ensure that it wasn't left blank
var noBlanks = [ "FirstName", "LastName", "Address", "City",
"Province", "PostalCode", "TelResidential",
"TelBusiness", "TelCell", "Email", "Job"];

for ( i=0; i < noBlanks.length; i++ ){
if (isEmpty(document.getElementById(noBlanks).value)) {

document.getElementById(noBlanks).style.backgroundColor=errColor;

var pTag = document.createElement('p');
pTag.innerHTML = noBlanks+" is a mandatory field.";
document.getElementById('FormErrors').appendChild(pTag);
frmOk = false;
}
}

if (frmOk == false) {
document.getElementById('FormErrors').style.display='block';
return false;
} else {
document.getElementById('FormErrors').style.display='none';
return true;
}
}

Any idea where I have made a mistake?

Might I ask you, what is officially the standard approach to doing
what I am wanting to do?

Why gEBI? I suppose getElementsByName would be more appropriate. Due to
an "odd" implementation IE also populates the id property of elements
with names with the name value.

But it's IE only.

The usual methods for manipulating the DOM: createElement(),
append/replace/removeChild(), ...

The "official" approach would be to generate each element, including
the TextNodes using the DOM API:

http://www.w3.org/TR/REC-DOM-Level-1/ecma-script-language-binding.html

Note that this can be significantly slower than using innerHTML in
some implementations if you're using many elements.
