    Question Help with color picker script please

    I am using this color picker script, the problem is my INPUT fields are named like arrays e.g. data[ContactForm][background] because I am using a framework for programming and thats how they are outputted. How do I call this correctly? How can I put that name properly in INPUTNAME below? Thanks for all the help.

    Its called like this:
    Code:
    <a href="#" onClick="cp.select(document.forms[0].INPUTNAME,'background');return false;" name="background" id="background">Pick</a>
    This is the color picker code:

    You could use the following:

    document.forms[0]['data[ContactForm][background]']

    Hi I made the changes... now it seems it wasn't that. I have declared the function like this:
    Code:
              <script type="text/javascript" src="/js/color_picker.js"></script>
              <script language="Javascript">
                var cp = new ColorPicker('window');
              </script>
    and have it linked like this:
    Code:
                <div class="field">
                  <div class="label">Background <a href="#background" onClick="cp.select(document.forms[0]['data[ContactForm][background]'],'background');return false;" name="background" id="background">+</a>:</div><div class="input required"><input name="data[ContactForm][background]" type="text" maxlength="255" size="15" value="" id="ContactFormBackground" /></div>
                  <div style="clear: both;"></div>
                </div>
    I am declaring the object but I don't know what the problem is .

    I get this error:
    Line: 54
    Char: 48
    Error: 'type' is null or not an object
    Code: 0

    Thanks for the help I really appreciate it.
    Have a good day.

    The following test code works fine on IE.

    Code html4strict:
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>Test</title>
    <script type="text/javascript" src="js/color_picker.js"></script>
    <script language="Javascript">
    var cp = new ColorPicker('window');
    </script>
    </head>
     
    <body>
    <form>
    <div class="field">
    	<div class="label">Background <a href="#background" onClick="cp.select(document.forms[0]['data[ContactForm][background]'],'background');return false;" name="background" id="background">+</a>:</div>
    	<div class="input required">
    		<input name="data[ContactForm][background]" type="text" maxlength="255" size="15" value="" id="ContactFormBackground" />	</div>
    	<div style="clear: both;"></div>
    </div>
    </form>
    </body>
    </html>

    You may have to provide a link to a test page for further troubleshooting.

    By the way, that test page really should have been coded in the following manner:

    Code css:
    input {
    	display: block;
    }

    Code html4strict:
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>Test</title>
    <link rel="stylesheet" type="text/css" href="css/style.css">
    </head>
     
    <body>
    <form id="myForm" action="process.php">
    	<p>
    		<label>Background <input type="text" name="data[ContactForm][background]" maxlength="255" size="15" value="" class="required"></label>
    	</p>
    </form>
    <script type="text/javascript" src="js/color_picker.js"></script>
    <script type="text/javascript" src="js/add_color_picker.js"></script>
    </body>
    </html>

    Code javascript:
    var myForm = document.getElementById('myForm');
    var el = myForm.elements['data[ContactForm][background]'];
    var a = document.createElement('a');
    a.appendChild(document.createTextNode('+'));
    a.id = 'background';
    a.href = '#';
    a.onclick = function (el) {
    	return function () {
    		var cp = new ColorPicker('window');
    		cp.select(el, 'background');
    	}
    }(el);
    el.parentNode.insertBefore(a, el);
