evol-colorpicker ·

evol-colorpicker is a web color picker which looks like the one in Microsoft Office 2010. 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.

   

Check the online demo for several examples.

Installation

Download or fork evol-colorpicker at GitHub.

git clone https://github.com/evoluteur/colorpicker

or use the npm package:

npm install evol-colorpicker

or install with Bower:

bower install evol-colorpicker

or use the nuget package:

dotnet add package evol-colorpicker

Usage

First, 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).

<script
  src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/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="js/evol-colorpicker.min.js"
  type="text/javascript"
  charset="utf-8"
></script>

The widget requires a jQuery UI theme to be present, as well as its own included base CSS file (evol-colorpicker.css). Here we use the "ui-lightness" theme as an example:

<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="css/evol-colorpicker.css" rel="stylesheet" type="text/css" />

Now, let's attach it to an existing <input> tag:

<script type="text/javascript">
  $(document).ready(function () {
    $("#mycolor").colorpicker();
  });
</script>

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

This will wrap it into a "holder" <div> and add another <div> beside it for the color box:

<div style="width:128px;">
  <input style="width:100px;" id="mycolor" class="colorPicker evo-cp0" />
  <div class="evo-colorind" style="background-color:#8db3e2"></div>
</div>

Using the same syntax, the widget can also be instanciated on a <div> or a <span> tag to show inline. In that case the generated HTML is the full palette.

Theming

evol-colorpicker is as easily themeable as any jQuery UI widget, using one of the jQuery UI themes or your own custom theme made with Themeroller.

Options

evol-colorpicker provides several options to customize its behaviour:

color (String)

Used to set the color value.

$("#mycolor").colorpicker({
  color: "#ffffff",
});

Defaults to null.

defaultPalette (String)

Used to set the default color palette. Possible values are "theme" or "web".

$("#mycolor").colorpicker({
  defaultPalette: "web",
});

Defaults to theme.

displayIndicator (Boolean)

Used to show color value on hover and click inside the palette.

$("#mycolor").colorpicker({
  displayIndicator: false,
});

Defaults to true.

hideButton (Boolean)

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.

$("#mycolor").colorpicker({
  hideButton: true,
});

Defaults to false.

history (Boolean)

Used to track selection history (shared among all instances of the colorpicker). The history keeps the last 28 colors selections.

$("#mycolor").colorpicker({
  history: false,
});

Defaults to true.

initialHistory (Array strings)

Used to provide a color selection history. Colors are provided as strings of hexadecimal color values.

$("#mycolor").colorpicker({
  initialHistory: ["#ff0000", "#00ff00", "#0000ff"],
});

Defaults to null.

showOn (String)

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.

$("#mycolor").colorpicker({
  showOn: "button",
});

Defaults to "both".

strings (String)

Used to translate the widget. It is a coma separated list of all labels used in the UI.

$("#mycolor").colorpicker({
  strings:
    "Couleurs de themes,Couleurs de base,Plus de couleurs,Moins de couleurs,Palette,Historique,Pas encore d'historique.",
});

Defaults to "Theme Colors,Standard Colors,Web Colors,Theme Colors,Back to Palette,History,No history yet.".

transparentColor (Boolean)

Allow for selection of the "transparent color". The hexadecimal value for the transparent color is "#0000ffff".

$("#mycolor").colorpicker({
  transparentColor: true,
});

Defaults to false.
