If you have a non-Java EE web application (e.g. a Node.js application) and intend to include Keikai into your application, there are 2 ways:
Just point to a zul with keikai in an HTML like:
Because an iframe belongs to a different browsing content(window) from its parent page, you need to communicate with spreadsheet by Window.postMessage().
zEmbedded.load() for embedding to render the specified zul in an HTML. This approach can render Keikai spreadsheet seamlessly into any HTML page without an iframe. It makes you easier to communicate between the parent HTML page and the embedded Keikai.
For usage of
zEmbedded, please check ZK Developer’s Reference/Integration/Miscellaneous/Embedded ZK Application for details and example project. Notice that this feature requires ZK EE (zkmax.jar).
