$('.clickto').click(function() { 
 
    $('[name="captcha"]').val('');

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 
 
<div class=""> 
 
    <div class="contactpagecaptchas"> 
 
    <img src="/captcha.php?rand=<?php echo rand();?>" class="contactpagecaptchass" id='captchaimg' /> 
 
    <p class="change"><a href="#" class="clickto">Click to change</a></p>

Answer 2

嘗試的JavaScript的onclick方法

<div id="abc" ><?php echo rand(); ?></div> 
<button onclick="refcaptcha()" > 
<script> 
function refcaptcha(){ 
    var x = document.getElementById("abc") 
    x.innerHTML = Math.floor((Math.random() * 1000000) + 1); 
    //if you want to clear the captcha code than assign '' to that id 
    //x.innerHTML = ''; 
} 
</script>
