Conditional Link based on Checkbox value

Question

I have a report where I have dynamically created a checkbox via HTMLDB_ITEM.CHECKBOX. I also have an edit link on each record.
The functionality that I need is, if the checkbox is unchecked then the link is active. If the checkbox is checked the link is inactive or when selected gives an alert and doesn't navigate to the edit page.
How can I do this

Answer 1

You mean like this? http://apex.oracle.com/pls/otn/f?p=43865:13
To achieve this I included a javascript function in the page's HTML Header as follows:
<script language="javascript">
function editIfChecked(idToCheck) {
if (document.getElementById('chk' + idToCheck).checked == true)
{redirect('f?p=&APP_ID.:14:&SESSION.::::P14_EMPNO:'+idToCheck);}
else
{alert('Sorry, Chief. You cannot edit this until you check the box.');}
</script>
Then change the edit link in your report to link to a URL like: javascript:editIfChecked(#EMPNO#);
Obviously change #EMPNO# to be the name of whatever unique ID column you're using. You'll need to change the javascript function as well so that it links to the right page in your app (unless it happens to also be page 14) and change the name of the item that is set (unless it happens to be P14_EMPNO).
Hope that helps,

Oh and also the argument passed to getElementById will have to be changed to reflect whatever ID you are giving to your checkboxes in your call yo htmldb_item.checkbox. I used this in the example above: htmldb_item.checkbox(1,empno,'id=chk'||empno)
