Junos Space Platform - UI Development

In JUNOS Space platform, a user can develop a UI by using the Ext-JS library. Ext-JS is a cross-browser rich internet application Framework. With Ext Designer, a user can develop pixel-perfect, cross-platform web apps with ease. Whether a user is a single developer or a development team, the Ext Designer component model keeps your code well structured, so even the largest applications can be easily maintained. Other developers' components plug in seamlessly. Best of all, Ext Designer provides an encyclopedic-collection of user interface widgets with an elegant starting theme.

Ext Designer offers an extraordinary range of user interface widgets. High performance scalable grids, trees, menus, and more. If you need it, we've probably already built it.

Ext includes a set of GUI-based form controls (or "widgets") for use within web applications:

  4. From Workspace Landing Page block (for Task it's Task Page URL block), select script from Script Name drop-down (this drop down lists all the scripts placed in XXXWeb\web\js directory) as shown below.

    OR upload a new JS file using upload button as shown below. The newly uploaded file appears in the dropdown.
