<h1>Example of Color Picker Built in a Dialog from Markup</h1>
<div class="exampleIntro">
<p>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.com/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.</p>
<p>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.com/yui/connection/">Connection Manager</a> and peruse the returned values that are echoed back to the page.</p>
</div>
<!--BEGIN SOURCE CODE FOR EXAMPLE =============================== -->
<script type="text/javascript">
//create a namespace object in the example namespace:
YAHOO.namespace("example.colorpicker")
//create a new object for this module:
YAHOO.example.colorpicker.inDialog = function() {
//Some shortcuts to use in our example:
var Event=YAHOO.util.Event,
Dom=YAHOO.util.Dom,
lang=YAHOO.lang;
return {
//In our initialization function, we'll create the dialog;
//in its render event, we'll create our Color Picker instance.
init: function() {
// Instantiate the Dialog
this.dialog = new YAHOO.widget.Dialog("yui-picker-panel", {
width : "500px",
fixedcenter : true,
visible : false,
constraintoviewport : true,
buttons : [ { text:"Submit", handler:this.handleSubmit, isDefault:true },
{ text:"Cancel", handler:this.handleCancel } ]
});
// Once the Dialog renders, we want to create our Color Picker
// instance.
this.dialog.renderEvent.subscribe(function() {
if (!this.picker) { //make sure that we haven't already created our Color Picker
YAHOO.log("Instantiating the color picker", "info", "example");
this.picker = new YAHOO.widget.ColorPicker("yui-picker", {
container: this.dialog
//Here are some other configurations we could use for our Picker:
//showcontrols: false, // default is true, false hides the entire set of controls
//showhexcontrols: true, // default is false
//showhsvcontrols: true // default is false
});
//listen to rgbChange to be notified about new values
this.picker.on("rgbChange", function(o) {
YAHOO.log(lang.dump(o), "info", "example");
});
}
});
// If we wanted to do form validation on our Dialog, this
// is where we'd do it. Remember to return true if validation
// passes; otherwise, your Dialog's submit method won't submit.
this.dialog.validate = function() {
return true;
};
// Wire up the success and failure handlers
this.dialog.callback = { success: this.handleSuccess, thisfailure: this.handleFailure };
// We're all set up with our Dialog's configurations;
// now, render the Dialog
this.dialog.render();
// We can wrap up initialization by wiring all of the buttons in our
// button dashboard to selectively show and hide parts of the
// Color Picker interface. Remember that "Event" here is an
// alias for YAHOO.util.Event and "Event.on" is therfor a shortcut
// for YAHOO.util.Event.onAvailable -- the standard Dom event attachment
// method:
Event.on("show", "click", this.dialog.show, this.dialog, true);
Event.on("hide", "click", this.dialog.hide, this.dialog, true);
Event.on("btnhsv", "click", function(e) {
var p = this.picker;
p.set(p.OPT.SHOW_HSV_CONTROLS, !p.get(p.OPT.SHOW_HSV_CONTROLS));

}, this.dialog, true);
//initialization complete:
YAHOO.log("Example initialization complete.", "info", "example");
},
//We'll wire this to our Dialog's submit button:
handleSubmit: function() {
//submit the Dialog:
this.submit();
//log this step to logger:
YAHOO.log("Dialog was submitted.", "info", "example");
},
//If the Dialog's cancel button is clicked,
//this function fires
handleCancel: function() {
//the cancel method automatically hides the Dialog:
this.cancel();
//log this step to logger:
YAHOO.log("Dialog was submitted.", "info", "example");
},
//We'll use Connection Manager to post our form data to the
//server; here, we set up our "success" handler.
handleSuccess: function(o) {
YAHOO.log("Connection Manager returned results to the handleSuccess method.", "info", "example");
var response = o.responseText;
//On Yahoo servers, we may get some page stamping;
//we can trim off the trailing comment:
response = response.split("<!")[0];
//write the response to the page:
response = "<strong>The data received by the server was the following:</strong> " + response;
document.getElementById("resp").innerHTML = response;
},
handleFailure: function(o) {
YAHOO.log("Connection Manager returned results to the handleFailure method.", "error", "example");
YAHOO.log("Response object:" + lang.dump(o), "error", "example");
}
}
}();
//The earliest safe moment to instantiate a Dialog (or any
//Container element is onDOMReady; we'll initialize then:
YAHOO.util.Event.onDOMReady(YAHOO.example.colorpicker.inDialog.init, YAHOO.example.colorpicker.inDialog, true);
