Embedding API

The Embedding API can be used to embed a Domino Leap form directly in another webpage without using an <iframe>. The Domino Leap form will be inserted into the DOM of the hosting page and can be interacted with using the Domino Leap JavaScript API or any custom JavaScript. Additionally, the style of items in the Domino Leap form can be customized by the CSS of the hosting page.

Example 1 - Declarative

<html> 
…  
<body>
   … 
   <div id="myLeapDiv"> <!-- Domino Leap form will go here --> </div> 
   …
   <script src="https://leap.example.com/volt-apps/api/volt.js" 
    data-leap-config="{launch: {appId: 'e9ec1ed3-c12b-4b5c-8f5e-7a6ff4800a55', formId: 'F_Form1', targetId: 'myLeapDiv'}}">
   </script> 
</body> 
</html>

Example 2 - Programmatic

<html> 
… 
<body> 
  …
  <div id="myLeapDiv"> <!-- Domino Leap form will go here --> </div> 
  …
  <script src="https://leap.example.com/volt-apps/api/volt.js"></script> 

  <script> 
    function onVoltFormSubmitted (BO) 
    { 
      alert ("submitted record id: " + submittedBO.getDataId());       
    } 

    function onVoltFormLoaded (app, launchParams) 
    { 
      app.getForm(launchParams.formId).connectEvent("afterSave", onLeapFormSubmitted); 
    } 

    Volt.onReady = function() { 
      var launchParams =  
      { 
      appId: 'e9ec1ed3-c12b-4b5c-8f5e-7a6ff4800a55', 
      formId: 'F_Form1', 
      target: document.getElementById("myLeapDiv"), 
      locale: 'fr-FR' 
      callback: onVoltFormLoaded 
      }; 
      Volt.launch(launchParams);  
    }; 

  </script> 

</body> 
</html>

Loading the Domino Leap Embedding UI

<script src="https://leap.example.com/volt-apps/api/volt.js" data-leap-config="[leap configuration]" id="leapJS'"></script>
  • id (optional) - fallback for older browsers; the value should always be "leapJS"
  • data-leap-config (optional) - JSON or the name of an existing JavaScript object. Properties:
    • locale (optional) - indicates the preferred locale to the Domino Leap API. For example, "fr-FR"
    • launch (optional) - equivalent to calling Volt.launch({…}) function with respective parameters (see below for more details)
    • overwriteExistingDojoConfig (optional) - In some environments, such as HCL Digital Experience or IBM WebSphere Portal, the djConfig or dojoConfig object may be defined on a page and not used. Set the value of this property to true to override it.

Loading the Domino Leap API will result in the creation of global object named Leap.

After initial load of the volt.js, you can define a Volt.onReady() function which will be called when the necessary Domino Leap resources have been loaded into the page and the API is ready to be used.

Embedding a form programmatically

To embed a Domino Leap form programmatically, call Volt.launch({launch_params});

{launch_params} properties:

Property Required? Description
appId Yes The Domino Leap application UUID.
For example, 'e9ec1ed3-c12b-4b5c-8f5e-7a6ff4800a55'
formId Yes The Domino Leap form ID.
For example, 'F_Form1'
recordId No The Domino Leap record ID.
For example, 'f7ab2ca2-c12b-4b5c-8f5e-7a6ff4800b69'
targetId Either target or targetId must be provided. The id of the HTML DOM element to embed the Domino Leap form within.
For example, 'myLeapFormDiv'
target Either target or targetId must be provided. The HTML DOM element to place the Domino Leap form within.
mode No Determines the mode for embedding. Possible values:
  • 'iframe': embeds the form in an <iframe> element. For complete isolation of the form, if necessary
  • 'embed' (default): embeds the form into the hosting page in a <div>
locale No Indicates the preferred locale for the embedded form.
For example, 'fr-FR'
prefSecMode No If the form supports both anonymous and authenticated usage, this property can be used to automatically choose the preferred security mode. Possible values:
  • 'anon': for anonymous usage
  • 'secure': for authenticated usage
callback No A callback function which will be called when the application launch completes successfully and the form is ready to be interacted with. The callback function will be passed the following parameters:
  • app: the Domino Leap JavaScript API application object.
  • launchParams: the original launch parameters object, for convenience

Known Limitations

  • Only one Domino Leap form can be embedded on the page at a time.
  • Once the Domino Leap form is embedded, it cannot be changed to a different form or reloaded.
  • The hosting page cannot contain any version of the Dojo JavaScript library. The Domino Leap Embedding API will load its own copy of the Dojo JavaScript library into the hosting page.
  • For authentication, it is expected that the hosting page and the Domino Leap server are configured with single sign-on (SSO). Domino Leap’s login UI will not display properly within the hosting page.
  • The embedding API cannot be set to an App Page

Cross-Domain Usage

If Domino Leap and the hosting page are in different domains, the Domino Leap front-end must be configured to return appropriate CORS headers.
