I have a form that uses CAPTCHA as a means of verification that the submitter is not spambot, or anything similar. I have a button next to the place where the user is supposed to input the letters/numbers in the image:
<button onclick="NewVerifyImage();">New image</button>
...and the NewVerifyImage() function looks like this:
var nReload = 5;
if (nReload <= 2)
if (nReload <= 0)
alert("Sorry, too many reloads.");
alert("Only " + nReload + " more reloads are allowed");
document.vimg.src = "verifyimg.php";
This calls a script called verifyimg.php, which would generate a new CAPTCHA image and place it in the image called "vimg" - however, when I click this "New Image" button, it's as though I've clicked submit - the form goes to the page I redirect the user to when info has been submitted.
Does anyone have any idea why it seems like this button is not calling the function properly?
