## Installation

Download or fork **evol-colorpicker** at [GitHub](https://github.com/evoluteur/colorpicker).

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

or use the [npm package](https://www.npmjs.com/package/evol-colorpicker):

```
npm install evol-colorpicker
```

or install with Bower:

```
bower install evol-colorpicker
```

<a name="Usage"></a>

## Usage

First, load [jQuery](http://jquery.com/) (v3.1 or greater), [jQuery UI](http://jqueryui.com/) (v1.12.1 or greater), and the plugin (for earlier version of jQuery-UI, use an earlier version of Colorpicker).

```html
<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](http://github.com/evoluteur/colorpicker/raw/master/css/evol-colorpicker.css)). Here we use the "ui-lightness" theme as an example:

```html
<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:

```html
<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:

```html
<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](http://jqueryui.com/themeroller/#themeGallery) or your own custom theme made with [Themeroller](http://jqueryui.com/themeroller/).

## Options

evol-colorpicker provides several options to customize its behaviour:

```javascript
$("#mycolor").colorpicker({
  color: "#ffffff",

```

```javascript
$("#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.

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

Defaults to _false_.

### history (Boolean)

```javascript
$("#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.

```javascript

  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.

```javascript
$("#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.

```javascript
$("#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)
