I have a form. It's still in testing, so don't correct the PHP or anything.

I have a javascript function called checkBoxState() what this is suppose to do, is get the checked box value, and if a user refreshed the page, the checkboxed origioanl value stays the same. Instead, it goes back to the default checked.

This worked earlier, until I enhanced it.

 

If you'd like to shorten down the form fields so that it does the same job, but doesn't look so big and messy, then feel free to do so it's your choice.

 

How can I fix what I am trying to do. Here is all the code for the whole page. (The javascript function is after <body> and the form is at the bottom above </body>

<?php 
session_start();
include ("../inc/config.php");
require_once('recaptchalib.php'); 
$publickey = "mykey";
$privatekey = "mykey";
$resp = null;
$error = null;
?>

I took a look at your code to see what it does and I see what you're trying to do. I'm not going to touch it though it doesn't look that pleasant with all the embedded events and non indented code.

 

Here is something that might be able to help you on your way. Read the comments and either firebug or change the console.log to alert to see what happens.

Hope it helps

 

<style>
#myform legend{
    font-weight:bold;
}
#myform label{
    width:220px;
    display:block;
}
</style>
<script type="text/javascript">
// wait for the page to be loaded (look into domready if you can its better)
window.onload = function() {
    // get checkbox elements by name attribute
    var checkboxes = document.getElementsByName("actor");

    // add onclick even for the checkboxes
    for(var i = 0; i< checkboxes.length; i++){
        var checkbox = checkboxes[i];

        //used closure to return the index here otherwise it would just always return the highest number
        checkbox.onclick = (function(index){
            return function(){
                //shows the current element clicked into firebug console
                console.log(this);
                // returns the index of the checkbox
                console.log("checkbox clicked with index:"+ index);
                //show status
                console.log("the status of the checkbox is now: "+this.checked);
            }
        })(i);

    }
}
</script>
<form id="myform">
    <fieldset>
        <legend>Which shall thou honor into the hall of shame</legend>
        <label><input type="checkbox" name="actor" value="Mr-T" />Mr-T </label>
        <label><input type="checkbox" name="actor" value="Chuck Norris" />Chuck Norris</label>
        <label><input type="checkbox" name="actor" value="Lorenzo Lamas"/>Lorenzo Lamas</label>
        <label><input type="checkbox" name="actor" value="Bob Saget"/>Bob Saget</label>
        <label><input type="checkbox" name="actor" value="Will Smith"/>Will Smith</label>
        <label><input type="checkbox" name="actor" value="Ben Stiller"/>Ben Stiller</label>
    </fieldset>
</form>
