Question

I am trying to make a script that updates the captcha image, that is loaded through live() function… It works, but it only updates the image 1 time on firefox, 2 times on safari… How can I make this to work multiple times?

jquery 1.4.2

relevant part of code:

/* captcha image change */
var rand = Math.random();

$('a.captcha_refresh').live('click', function() {
    $('img.captcha').attr("src", 'captchashow.php?sid=' + rand);
}); 

thanks,
brm

Answer 1

This depends on your implementation, but you are reusing the same random value on all request. You may want:

var rand;

$('a.captcha_refresh').live('click', function() {
    rand = Math.random(); //new value
    $('img.captcha').attr("src", 'captchashow.php?sid=' + rand);
}); 

That way rand keeps changing, but you see its latest value.
