Question

index.html: using jquery for selecting colors

I attempted to integrate a jQuery plugin into my application, but it doesn't seem to be working. In the head section of my code, I have included:

<link rel="stylesheet" media="screen" type="text/css" href="./style/colorpicker.css" />
<script type="text/javascript" src="./scripts/jqueryColorPicker/colorpicker.js"></script>

and somewhere in the body:

<script>
        $("./images/colorwheel.png").ColorPicker({
            color: '#0000ff',
            onShow: function (colpkr) {
                $(colpkr).fadeIn(500);
                return false;
            },
            onHide: function (colpkr) {
                $(colpkr).fadeOut(500);
                return false;
            },
            onChange: function (hsb, hex, rgb) {
                $('#footer').css('backgroundColor', '#' + hex);
                $('#header').css('backgroundColor', '#' + hex);
            }
        });
    </script>

However, the color wheel did not appear on my page. I am relatively new to using jQuery and could use some guidance. Can anyone help me figure out what went wrong?

Answer №1

Your current selector for the color picker $("./images/colorwheel.png") needs to be adjusted.

In order for the color picker to function properly, you must designate an HTML element for it to work on.

Consider adding something like this:

<div class="someClass"><div>

Then, initialize the color picker over it using the following code:

$(".someClass").ColorPicker({
    color: '#0000ff',
    onShow: function (colpkr) {
        $(colpkr).fadeIn(500);
        return false;
    },
    onHide: function (colpkr) {
        $(colpkr).fadeOut(500);
        return false;
    },
    onChange: function (hsb, hex, rgb) {
        $('#footer').css('backgroundColor', '#' + hex);
        $('#header').css('backgroundColor', '#' + hex);
    }
});

1. Ensure that the jquery library is included in the <head>.

2. Double check your selector, for example if you want to link the color picker to textbox #colorpicker, the correct code should be:

<input type="text" id="colorpicker">
    
$("#colorPicker").ColorPicker({ ... });

3. Remember to place the code within $(document).ready ..

$(document).ready(function() {
    $("#colorPicker").ColorPicker({ ... });
});

To start, create a container for your ColorPicker:

<input type="text" id="colorPicker">

Next, set up the ColorPicker on that specific element:

$("#colorPicker").ColorPicker({
...

It's important to ensure your code runs after the page has fully loaded using ready:

$(document).ready(function() {
    //Your code
});

If you have multiple color pickers, consider using classes instead of ids.
