Simple JQuery UI Enabled Color Picker – Evol-colorpicker.js

It can be used inline or as a popup bound to a text box. It comes with several color palettes, can track selection history and supports “transparent” color. It is a full jQuery UI widget, supporting various configurations and themes.

Integrate evol-colorpicker on input box

Libraries

Load jQuery UI theme CSS, as well as its own included base CSS file (evol-colorpicker.css). Here we use the “ui-lightness” theme as an example. Then load jQuery (v3.1 or greater), jQuery UI (v1.12.1 or greater), and the plugin (for earlier version of jQuery-UI, use an earlier version of Colorpicker).

<!--CSS-->
<link rel="stylesheet" type="text/css" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.12.1/themes/ui-lightness/jquery-ui.css">
<link href="evol-colorpicker.min.css" rel="stylesheet" type="text/css">
<!--JS-->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js" type="text/javascript" charset="utf-8"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.12.1/jquery-ui.min.js" type="text/javascript" charset="utf-8"></script>
<script src="evol-colorpicker.min.js" type="text/javascript" charset="utf-8"></script>

Now create simple text box, where on focus a color picker popup will open to select any color code you want.

<input style="width:100px;" id="mycolor" />

$(function() {  
 $('#mycolor').colorpicker();
});

Create a basic inline color picker with “web” default palette on your web page.

<div id="inline"></div>

$(function() {  
	$('#inline').colorpicker({
		defaultPalette:'web'
	});
});

You can customize colorpicker by using following options.

$(function() {  
	$("#mycolor").colorpicker({
		color: "#ffffff", //Used to set the color value.
		defaultPalette: 'web', //Used to set the default color palette. Possible values are "theme" or "web".
		displayIndicator:false, //Used to show color value on hover and click inside the palette.
		hideButton: true, //When binding the colorpicker to a textbox, a colored button will be added to the right of the textbox unless hideButton is set to true. This option doens't have any effect if the colorpicker is bound to a DIV.
		history: false, //Used to track selection history (shared among all instances of the colorpicker). The history keeps the last 28 colors selections.
		initialHistory: ["#ff0000", "#00ff00", "#0000ff"], //Used to provide a color selection history. Colors are provided as strings of hexadecimal color values.
		showOn: "button", //Have the colorpicker appear automatically when the field receives focus ("focus"), appear only when a button is clicked ("button"), or appear when either event takes place ("both"). This option only takes effect when the color picker is instanciated on a textbox.
		transparentColor: true //Allow for selection of the "transparent color". The hexadecimal value for the transparent color is "#0000ffff".  
	});
});

There are list of public methods to customize the color picker.

$(function() {  
	$("#mycolor").colorpicker("clear"); //Clears the color value (and close the popup palette if opened).
	$("#mycolor").colorpicker("enable"); //Get the currently selected color value (returned as a string).
	$("#mycolor").colorpicker("disable"); //Get the currently selected color value (returned as a string).
	$("#mycolor").colorpicker("isDisabled"); //Get the currently selected color value (returned as a string).
	//Get or set the currently selected color value (as a string, ie. "#d0d0d0").
	var colorValue = $("#mycolor").colorpicker("val");
	$("#mycolor").colorpicker("val", "#d0d0d0");
	$("#mycolor").colorpicker("showPalette"); //Show the palette (when using the widget as a popup).
	$("#mycolor").colorpicker("hidePalette"); //Hide the palette (when using the widget as a popup).
});

List of events.

// This event is triggered when a color is selected.
$("#mycolor").on("change.color", function(event, color){
    $('#title').css('background-color', color);
});
This event is triggered when the mouse moves over a color box on the palette.
$("#mycolor").on("mouseover.color", function(event, color){
    $('#title').css('background-color', color);
});

I hope it can help you..
