Hi,

I am trying to update part of a webpage using javascript. The bit that gets
updated will have a variable number of links written to it.

I have done this successfully by rewriting the whole page but this seems
like overkill (and a maintenance problem too potentially).

I thought about defining the area to be updated using a div. Something like
this:

<div id="results">Results will go here</div>

with the javascript doing something like:

var src = "blah blah blah";
document.getElementById('results').childNodes[0].nodeValue = src;

This works if src is just text. If it is HTML, say:

var src="<p><a href=\"some_file.html\">Some file</a></p>";

Then inside the div instead of getting a link to some_file.html I get the
raw HTML.

Is there either a way round this problem or a much better way of doing it in
the first place?

Thanks

Learn the DOM e.g.
var p = document.createElement('p');
var link = document.createElement('a');
a.href = 'some_file.html';
p.appendChild(a);

var resultsDiv = document.getElementById('results');
while (resultsDiv.hasChildNodes()) {
resultsDiv.removeChild(resultsDiv.lastChild);
}

resultsDiv.appendChild(p);

or help yourself with innerHTML

resultsDiv.innerHTML = '<p><a ...>...<\/a><\/p>';
