Question

this line renews the captcha image, it should clear the inputbox ‘captcha’ aswell.

    <div id="refresh_button"><a href="#" onclick="refreshimg();return false;"><img src="refresh.gif"/></a></div>

    <input type="text" maxlength="6" name="captcha" id="captcha" class="captcha_inputbox" />

So I have to modify the onClick, but I can’t find this, not even with google.

Your help is much appreciated

Answer 1

You can clear out the textbox’s value by using:

document.getElementById('captcha').value = '';

Alternatively, if you’re using jQuery:

$('#captcha').val('');
