Developer Guide
ConsentControl
consists of 2 main elements: Banner and Preferences Dialog. Use containerElementOrId
, culture
, onPreferencesChanged
, cookieCategories
, options
to create an instance. culture
will be used to determine the direction of the banner and preferences dialog.
var cc = new ConsentControl(
// here the banner will be inserted, can be HTMLElement or element id
containerElementOrId: string | HTMLElement,
// culture can be just language "en" or language-country "en-us".
// Based on language RTL should be applied (https://www.w3.org/International/questions/qa-scripts.en)
culture: string,
// callback function, called on preferences changes (via "Accept All", "Reject All" or "Save changes"),
// must pass cookieCategoriePreferences, see ICookieCategoriesPreferences in Data types
onPreferencesChanged: (cookieCategoriesPreferences: ICookieCategoriesPreferences) => void,
// optional, see ICookieCategory in Data types
cookieCategories?: ICookieCategory[],
// optional, see IOptions in Data types
options?: IOptions
);
-
setTextResources(textResources: ITextResources)
can be used to set the texts. -
createTheme(name: string, theme: ITheme)
can be used to create the new theme.name
is the name of this new theme, which can be used byapplyTheme(themeName: string)
.theme
is the new theme object.ConsentControl
consists of three built in themes,light
,dark
, andhigh-contrast
.dark
andhigh-contrast
themes are from Microsoft Docs. -
You can apply the theme manually by using
applyTheme(themeName: string)
.themeName
is the name of the theme which you want to apply.If you want to apply a new theme, you need to call
createTheme(name: string, theme: ITheme)
first, and then callapplyTheme(themeName: string)
let theme: ITheme = { "close-button-color": "#000080", "secondary-button-disabled-opacity": "1", "secondary-button-hover-shadow": "none", "primary-button-disabled-opacity": "0.65", "primary-button-hover-border": "none", "primary-button-disabled-border": "1px double #3CB371", "primary-button-hover-shadow": "2px 5px 7px #A12A29", "banner-background-color": "#BA5583", "dialog-background-color": "#32CD32", "primary-button-color": "#4B30AE", "text-color": "#800000", "secondary-button-color": "#00FA9A", "secondary-button-disabled-color": "#7B68EE", "secondary-button-border": "1px dashed #969696", } // Create a new theme, named "medium" cc.createTheme("medium", theme); // Apply the "medium" theme cc.applyTheme("medium");

-
getDirection()

Data types
There are six data types: ICookieCategory
, ITextResources
, ICookieCategoriesPreferences
, IOptions
, IThemes
, and ITheme
.
-
ICookieCategory
is used to create cookie categories that will be showed in the preferences dialog. -
ITextResources
is the texts that will be used in the banner and preferences dialog. -
ICookieCategoriesPreferences
is used to store the preferences in each cookie categories. -
IOptions
is the options for the banner. It contains four parts,textResources
,themes
,initialTheme
, andstylesNonce
.-
textResources
is the initial text resources for texts. -
themes
is a collections of themes that can be applied to the banner and preferences dialog. -
initialTheme
is the initial theme that you want to applied before you callapplyTheme(themeName: string)
. -
stylesNonce
is thenonce
attribute for<style>
tag.
The
nonce
attribute enables you to whitelist certain inline script and style elements, while avoiding use of the Content Security Policy (CSP) unsafe-inline directive (which would allow all inline script/style), so that you still retain the key CSP feature of disallowing inline script/style in general. Also see CSP: style-src for more information. IfstylesNonce
is undefined, thenonce
attribute will not be added to<style>
tag. -
-
IThemes
is a collections of themes. The properties names are the names of each themes, and the values are the theme objects. -
ITheme
is the theme object. It contains required properties and optional properties. Optional properties can be calculated by a built in method with required ones.
// All categories should be replaced with the passed ones in the control
interface ICookieCategory {
id: string;
name: string;
descHtml: string;
// optional, prevents toggling the category.
// True only for categories like Essential cookies.
isUnswitchable?: boolean;
