Example of Color Picker Built in a Dialog from Markup

This example differs from <a href="colorpicker-dialog-from-script.html">the previous example</a> only in that the markup for the Color Picker instance is placed on the page rather than being generated automatically by the control. By exploring this markup and the CSS file accompanying Color Picker <a href="http://developer.yahoo.ru/yui/download/">in the YUI download</a>, you will get a sense of how to create your own customized interface for Color Picker that reflects the design imperatives of your own implementation.

To interact with this example, click the "Show Color Picker" button below. You can then experiment with enabling/disabling portions of the picker interface via the dashboard and submit color data via <a href="http://developer.yahoo.ru/yui/connection/">Connection Manager</a> and peruse the returned values that are echoed back to the page.

Example of Color Picker Built in a Dialog via JavaScript

This example explores the implementation of a Color Picker Control within the context of a popup <a href="http://developer.yahoo.ru/yui/container/dialog/">Dialog</a>. The control can be called up in the floating Dialog, a color can be chosen, and upon submission of the Color Picker"s value the color data is submitted to the server using Dialog"s built-in support for <a href="http://developer.yahoo.ru/yui/connection/">Connection Manager</a>.

Click the "Show Color Picker" button to get started. Use the other buttons on the configuration dashboard to explore different configurations of the Color Picker Controls. When you submit your color choice, the example uses Connection Manager to echo back <a href="http://developer.yahoo.ru/yui/colorpicker/#formdata">the form fields that were passed to the server</a>.

Inline Color Picker Control from Script

The simplest way to implement the Color Picker Control is to do so entirely via script. In this example, a Color Picker Control is placed on the page via script and allowed to create its own DOM structure. In cases where you"ve provided other form controls on the page for color specification (ie, controls not dependent on JavaScript), this approach allows you to provide a richer visual experience for sighted users with JavaScript enabled.

<button id="reset">Reset Color to White</button> <button id="gethex">Write current hex value to the Logger</button> <script type="text/javascript"> (function() {

Example of Specifying Custom Labels and Element IDs for Color Picker

The Color Picker below looks much like the pickers in other examples. However, two changes have been made:

  1. Element IDs have been customized: Color Picker uses a default set of element IDs when it creates the DOM for your picker instance. If you want to control those IDs, you may need to change these defaults. (In addition to the method described here, you can also pass in new IDs via the constructor; see the <a href="http://developer.yahoo.ru/yui/colorpicker/#customIds">Customizing Element IDs section of the Color Picker User"s Guide</a>.
  2. Form labels have been customized: Instead of R, G, and B, we"re using here the strings "Red", "Green", and "Blue". This illustrates the technique you might use to translate your Color Picker interface into multiple languages.

<script type="text/javascript"> //dump the contents of the element IDs object to the Logger: YAHOO.log("The full contents of the YAHOO.widget.ColorPicker.prototype.ID object: " + YAHOO.lang.dump(YAHOO.widget.ColorPicker.prototype.ID), "info", "example"); //dump the contents of the interface text strings object to the Logger: YAHOO.log("The full contents of the YAHOO.widget.ColorPicker.prototype.TXT object: " + YAHOO.lang.dump(YAHOO.widget.ColorPicker.prototype.TXT), "info", "example"); //Using an anonymous function keeps our variables //out of the global namespace. (function() { 

   var Event = YAHOO.util.Event,
       picker;
   // this is how to override some or all of the
   // element ids used by the control
   var ids = YAHOO.lang.merge(
       YAHOO.widget.ColorPicker.prototype.ID, {
           R: "custom_R",
           G: "custom_G",
           B: "custom_B"
       });
   // this is how to change the text generated
   // by the control
   var txt = YAHOO.lang.merge(
       YAHOO.widget.ColorPicker.prototype.TXT, {
           R: "Red",
           G: "Green",
           B: "Blue"
       });
 
 //Having changed the default element ids, you can
 //instantiate your picker:
   Event.onDOMReady(function() {
           picker = new YAHOO.widget.ColorPicker("yui-picker-panel", {
                   showhsvcontrols: true,
                   showhexcontrols: true,
                   ids: ids,
                   txt: txt,
                   animate: false
               });
       });

})(); </script>
