Methods

(static) apps() → {Array}

Returns an array with app launchers. The data returned is an internal data structure and should not be modified.

Returns:
{Array} the loaded app launchers (read-only)
Source:
RapidContext_App.js, line 119

(static) callApp(app, method, argsopt) → {Promise}

Performs an asynchronous call to a method in an app. If only the class name or launcher is specified, the most recently created instance will be used. If no instance is running, one will be started. Also, before calling the app method, the app UI will be focused.

Parameters:
Name Type Attributes Description
app {string|Object} the app id, instance, class name or launcher
method {string} the app method name
args {Mixed} <optional>
 additional parameters sent to method
Returns:
{Promise} a RapidContext.Async promise that will resolve with the result of the call on success
Source:
RapidContext_App.js, line 380

(static) callProc(name, argsopt) → {Promise}

Performs an asynchronous procedure call.

Parameters:
Name Type Attributes Description
name {string} the procedure name
args {Array} <optional>
 the array of arguments, or null
Returns:
{Promise} a RapidContext.Async promise that will resolve with the response data on success
Source:
RapidContext_App.js, line 430

(static) downloadFile(url, dataopt)

Downloads a file to the user desktop. This works by creating a new window or an inner frame which downloads the file from the server. Due to Content-Disposition headers being set on the server, the web browser will popup a dialog for the user to save the file. This function can also be used for saving a file that doesn't exist by first posting the file (text) content to the server.

Parameters:
Name Type Attributes Description
url {string} the URL or filename to download
data {string} <optional>
 the optional file data (if not available on the server-side)
Source:
RapidContext_App.js, line 715

(static) findApp(app) → {Object}

Finds the app launcher from an app instance, class name or launcher. In the last case, the matching cached launcher will be returned.

Parameters:
Name Type Description
app {string|Object} the app id, instance, class name or launcher
Returns:
{Object} the read-only app launcher, or null if not found
Source:
RapidContext_App.js, line 148

(static) init(appopt) → {Promise}

Initializes the platform, API:s and RapidContext UI. If an app identifier is provided, the default platform UI will not be created. Instead the app will be launched with the root document as its UI container.

Parameters:
Name Type Attributes Description
app {string|Object} <optional>
 the app id or class name to start
Returns:
{Promise} a promise that will resolve when initialization has either completed or failed
Source:
RapidContext_App.js, line 43

(static) loadJSON(url, paramsopt, optionsopt) → {Promise}

Performs an asynchronous HTTP request and parses the JSON response. The request parameters are automatically encoded to query string or JSON format, depending on the Content-Type header. The parameters will be sent either in the URL or as the request payload (depending on the HTTP method).

Parameters:
Name Type Attributes Description
url {string} the URL to request
params {Object} <optional>
 the request parameters, or null
options {Object} <optional>
 the request options, or null
Returns:
{Promise} a RapidContext.Async promise that will resolve with the parsed response JSON on success
Source:
RapidContext_App.js, line 562

(static) loadScript(url) → {Promise}

Loads a JavaScript to the the current page. The script is loaded by inserting a <script> tag in the document <head>. Function definitions and values must therefore be stored to global variables by the script to become accessible after loading. If the script is already loaded, the promise will resolve immediately.

Parameters:
Name Type Description
url {string} the URL to the script
Returns:
{Promise} a RapidContext.Async promise that will resolve when the script has loaded
See:
Use dynamic `import()` instead, if supported by the environment.
Source:
RapidContext_App.js, line 671

(static) loadStyles(url) → {Promise}

Loads a CSS stylesheet to the the current page asynchronously. The stylesheet is loaded by inserting a <link> tag in the document head. If the stylesheet is already loaded, the promise will resolve immediately.

Parameters:
Name Type Description
url {string} the URL to the stylesheet
Returns:
{Promise} a RapidContext.Async promise that will callback when the stylesheet has been loaded
Source:
RapidContext_App.js, line 692

(static) loadText(url, paramsopt, optionsopt) → {Promise}

Performs an asynchronous HTTP request for a text document. The request parameters are automatically encoded to query string or JSON format, depending on the Content-Type header. The parameters will be sent either in the URL or as the request payload (depending on the HTTP method).

Parameters:
Name Type Attributes Description
url {string} the URL to request
params {Object} <optional>
 the request parameters, or null
options {Object} <optional>
 the request options, or null

{Promise} a RapidContext.Async promise that will resolve with the response text on success
Source:
RapidContext_App.js, line 585

(static) loadXHR(url, paramsopt, optionsopt) → {Promise}

Performs an asynchronous HTTP request. The request parameters are automatically encoded to query string or JSON format, depending on the Content-Type header. The parameters will be sent either in the URL or as the request payload (depending on the HTTP method).

Parameters:
Name Type Attributes Description
url {string} the URL to request
params {Object} <optional>
 the request parameters, or null
options {Object} <optional>
 the request options, or null
Returns:
{Promise} a RapidContext.Async promise that will resolve with the XMLHttpRequest instance on success
Source:
RapidContext_App.js, line 631

(static) loadXML(url, paramsopt, optionsopt) → {Promise}

Performs an asynchronous HTTP request for an XML document. The request parameters are automatically encoded to query string or JSON format, depending on the Content-Type header. The parameters will be sent either in the URL or as the request payload (depending on the HTTP method).

Parameters:
Name Type Attributes Description
url {string} the URL to request
params {Object} <optional>
 the request parameters, or null
options {Object} <optional>
 the request options, or null

Source:
RapidContext_App.js, line 608

(static) login(login, password, tokenopt) → {Promise}

Performs an asynchronous login. If the current session is already bound to a user, that session will be terminated and a new one will be created. If an authentication token is specified, the login and password fields are not used (can be null).

Parameters:
Name Type Attributes Description
login {string} the user login name or email address
password {string} the password to authenticate the user
token {string} <optional>
 the authentication token to identify user/password

(static) logout(reloadopt) → {Promise}

Performs an asyncronous logout. This function terminates the current session and either reloads the browser window or returns a deferred object that will produce either a callback or an errback response.

Parameters:
Name Type Attributes Default Description
reload {boolean} <optional>
 true the reload browser flag
Returns:
{Promise} a RapidContext.Async promise that will resolve when user is logged out
Source:
RapidContext_App.js, line 538

(static) startApp(app, containeropt) → {Promise}

Creates and starts an app instance. Normally apps are started in the default app tab container or in a provided widget DOM node. By specifying a newly created window object as the parent container, apps can also be launched into separate windows.

Note that when a new window is used, the returned deferred will callback immediately with a null app instance (normal app communication is not possible cross-window).

Parameters:
Name Type Attributes Description
app {string|Object} the app id, class name or launcher
container {Widget/Window} <optional>
 the app container widget or window, defaults to create a new pane in the app tab container
Returns:
{Promise} a RapidContext.Async promise that will resolve when the app has launched
Example:
// Starts the help app in a new tab
RapidContext.App.startApp('help');

// Starts the help app in a new window
RapidContext.App.startApp('help', window.open());
