Question

On this page with captcha demo:

http://www.tutorialcadet.com/demo/ajaxform/

the captcha image is not refreshing (when clicking on the image) in internet explorer. In firefox. chrome, opera it works fine.

It throws in explorer this popu up error:

Line: 155
Error: Object doesn't support this property or method

Then when I check the source code in explorer I see this on line 155:

<td><div id="captchaimage"><a href="SITE_BASE/register/" id="refreshimg" onclick="refreshimg(); return false;" title="Click to refresh image"><img src="captcha/image.php?1311183335" alt="Captcha image" width="132" height="46" align="left" /></a></div></td>

Then when I click on the image again, another error popup shows up:

Line: 1
Error: Object doesn't support this property or method

When I view the source code I see a ?blank row? on the first row.
Here is the screen what I mean by blank first row:

Any suggestion how to solve this? This happens only in internet explorer. I am currently using 9. Is this some kind of internet explorer bug or?

Answer 1

None of the JS files define the method refreshimg(), hence the error.

Also captcha.js already has the code to handle the captcha.

Remove the refreshimage(); part from the onclick of the #refreshimg anchor.

The anchor element should now look like:

<a href="SITE_BASE/register/" id="refreshimg" onclick="return false;" title="Click to refresh image">
 <img src="captcha/image.php?1311183335" alt="Captcha image" width="132" height="46" align="left" />
</a>
