基于jQuery UI的颜色选择器ColorPicker使用手册

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.

$("#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.”.
