Details

This page uses the JavaScript Client API for Lightstreamer to handle the communications with Lightstreamer Server and uses jqGrid to display the real-time data pushed by Lightstreamer Server.
A Lightstreamer Subscription is used for subscribing to the data. The onItemUpdate callback implementation acts as a bridge between Lightstreamer and jqGrid, by injecting the real-time updates through the setRowData function.
Click on the Name column header to resort the stocks in the table.

The demo includes the following client-side functionalities:

  • A Subscription containing 10 items, subscribed to in MERGE mode.

Install

If you want to install a version of this demo pointing to your local Lightstreamer Server, follow these steps:

  • Note that, as prerequisite, the Lightstreamer - Stock- List Demo - Java Adapter has to be deployed on your local Lightstreamer Server instance. Please check out that project and follow the installation instructions provided with it.
  • Launch Lightstreamer Server.
  • Get the lightstreamer.js file from the Lightstreamer 5 Colosseo distribution and put it in the src/js folder of the demo (if that is the case, please create it). Alternatively, you can build a lightstreamer.js file from the online generator. In that case, be sure to include the LightstreamerClient, Subscription, ConnectionSharing, and StatusWidget modules and to use the "Use AMD" version.
  • Get the require.js file form requirejs.org and put it in the src/js folder of the demo.
  • To use jqGrid, first, a UI theme css file should be loaded. Download the desired theme (or build a custom one) from jQueryUI site, get from the zip file the jquery-ui-1.x.x.custom.min.css file and src/images folder, and put them in src/css folder of the project.
  • Download the jqGrid package from the site section downloads. Get the i18n folder and jquery.jqGrid.min.js, jquery-1.9.0.min.js files and copy them in src/js folder of this project. Then get the ui.jqgrid.css file and copy it in src/css folder of this project.

You can deploy the demo to use the Lightstreamer server as Web server or in any external Web Server you are running. If you choose the former case, please create the folders <LS_HOME>/pages/demos/[demo_name] then copy here the contents of the src folder of this project.
The client demos configuration assumes that Lightstreamer Server, Lightstreamer Adapters, and this client are launched on the same machine. If you need to target a different Lightstreamer server, please search this line:

var lsClient = new LightstreamerClient(protocolToUse+"//localhost:"+portToUse,"DEMO");

in lsClient.js and change it accordingly.

The demo is now ready to be launched.
