Hi,
I have now a probleme in refreshing image;
After displaying image in the form i have a little icon whene i click
it call an ajax request to the same action (home/showCaptcha)
for the goal to reload the captch with new caractere but the captcha
refresh fail(in firebug i see the response it's a strange caractere)
This the code i use to refresh the img (jQuery):
<script type="text/javascript">
$(document).bind('ready', function(){
$('#refresh_captcha').bind('click', function(){
$.ajax({
type: "POST",
url: "<?php echo url_for('home/showCaptcha')?>",
success: function(img){
$('#img_captcha').attr('src', img);
}
});
});
});
</script>
Best regard
Ahmed
