poll script

[Johnny26652]

Hi, looking around for a asp poll script. Have found quite a few but not one that does what i want.
If you know the bbc site they usually run a poll with one question, a yes or no option but once voted the panel changes to a bar chart with results in them.

This is what I want to do but can't for the life of me find a script out there that does it.

I just wrote: http://www.rodsdot.com/ee/poll_vote_ajax_asp.asp

Unfortunately I'm getting an error in IE, but check it out in Firefox and see if it is something you want me to pursue.

The IE error is fixed.

The original page displays the poll and vote buttons. The vote is posted to an ASP post handling page which receives the vote, stores it in the database then queries the database for the total results for each choice.  The original page receives the totals via the remote scripting object results, parses them and creates a percentage, then displays a dynamic bar chart of the results in place of the vote area.

On my site's example page nothing happens, or after copying the code to your site nothing happens?

I just tested my site's page in Opera, Firefox and IE successfully.

If it is your site's test page that isn't working send me a link or post the code so I can debug.

i copied your code to my site and nothing happens... i copied and pasted so didn't change anything.. I don't have a web address just trying it on local web..

i was wondering if someone else tried this and had problems executing..

are there any ajax/asp tutorials... other than what you have on experts?

thanks again

What did you name the pages?

Note the second page name is hard coded in the JavaScript as 'poll_vote_ajax_asp_dovote.asp

If you named it something else and did not change the script in the first page, then you'll get a 404 error and never return anything.


For debugging use this function in place of the former, and add a division in the HTML.

Code:

function handleHttpResponse(pObjRequest, pElementId) {
if (pObjRequest.readyState==4) {
if (pObjRequest.status==200) {
document.getElementById('voteform').style.display='none';
document.getElementById('waiting').style.display='none';
document.getElementById('results').style.display='inline';
var votes = pObjRequest.responseText.split(',');
var tmp =  votes[0].split('=');
var yeses = parseInt(tmp[1]);
tmp =  votes[1].split('=');
var nos = parseInt(tmp[1]);

var yp = Math.round((yeses / (yeses + nos)) * 100);
var yn = Math.round((nos / (yeses + nos)) * 100);

var barchart = '<span>Do people Like broccoli</span><br>';
barchart += '<div class="votes"><div class="chart"><img border="0" src="images/1x15navy.gif" width="'+yp+'" height="15"></div>Yes: '+yp+'%</div>';
barchart += '<div class="votes"><div class="chart"><img border="0" src="images/1x15navy.gif" width="'+yn+'" height="15"></div>No: '+yn+'%</div>';
document.getElementById(pElementId).innerHTML=barchart;
pObjRequest=null;
}else{
document.getElementById('statuslog').innerHTML += 'Status: '+pObjRequest.status+'<br>';
}
}else{
document.getElementById('statuslog').innerHTML += 'Ready State: '+pObjRequest.readyState+'<br>';
}
}

And in the HTML

Code:

<div id="statuslog">Ajax Status:<br></div>

Which will show you what is going on with the response object.  If and when it fails it will be easy to determine why.

And of course, all of this assumes your local web is capable of running an ASP page.  e.g.

<%
response.write("ASP Works")
%>

Saved in a page all by it self called test.asp works correctly.
