How to add closing button to notices ?

Question

I tried to override the Error function on theme base to add a closing button but it seems that the error message HTML is generated with Javascript through this function :
 

qa_ajax_post('vote', {postid:postid, vote:vote, code:code},

function(lines) {

if (lines[0]=='1') {

qa_set_inner_html(document.getElementById('voting_'+postid), 'voting', lines.slice(1).join("\n"));

 

} else if (lines[0]=='0') {

var mess=document.getElementById('errorbox');

 

if (!mess) {

var mess=document.createElement('div');

mess.id='errorbox';

mess.className='qa-error';

mess.innerHTML=lines[1];

mess.style.display='none';

}

 

var postelem=document.getElementById(anchor);

var e=postelem.parentNode.insertBefore(mess, postelem);

qa_reveal(e);

 

} else

qa_ajax_error();

}

);

 

 

I am new to JS, any help please to add HTML Button and making works through JS.

thank you !

Thanks Scott ! 

It does work  by inserting  the button into mess.innerHTML , using javascript concatination,
As for other notices, the tip is to add button to the error function on theme-base file.

Thanks again

The contents of the error box are set to what is returned from the AJAX call (i.e. `lines[1]`). So you can find where that content is generated (it should be one of the qa-ajax-*.php files) then add some HTML to that.
