Hi Community,

In this article I will demonstrate below steps to add Interactive map and visualize geographic data to web application:

• Step1 : Install Application
• Step2 : Create CSP Page
• Step3 : Extend dc.IrisGeoMap.Folium class
• Step4 : Invoke DrawGeoDetails() Method

So Let us start.

Step1 : Install Application

First of all we need to install iris-geo-map application by using ZPM

zpm "install iris-geo-map"

How to manipulate the code of the studio? Error messages, adding new items in the general options, formatting of the code, code typing...

Hi,

If I test the Native api for Node.js from the documentation, I noticed (if I'm correct) all methods and calls are synchronous. By default due to the nature of Node.js, there is only one thread of execution and normally all JavaScript methods and all calls should be asynchronous and use either a callback function (the "old way") or promises or the async/await contruct to return their result, e.g.:

Hi everyone!

I am recruiting on a fully remote Intersystems Developer. This role will be a long term contract to begin with high likelihood of extensions or conversion permanent. Please check out the job description down below and feel free to send me an email with your resume: Spencer.Frey@insightglobal.com

I have a few Radio buttons, some of which have to have the same value. I need to know which one the user have selected, so I am using text, however it does not work well so far.

Example:
I have 4 Radio buttons: Apple, Pear, Lemon and Orange, with values: Apple, Pear have Value 1, and Lemon and Orange have Value of 2
(this unfortunatelly cannot be changed for this particular application)

I need to figure out that the user picked specifically Apple, so I am using text as follows:

I started to get the following error when trying to save HTML and js files after editing in VSCode. This used to work fine, csp still works too.

ERROR #16006: Document 'xxx.html' name is invalid

Is there now a setting that I am missing? I did check but saw nothing that was obviously wrong.

With the release of InterSystems IRIS 2021.2 Preview and all-new LOAD DATA functionality dataset can by added with Objectscript Package Manager (ZPM)

Medical Datasets contains following 12 datasets. For dataset tables and data details please visit ONLINE DEMO by using SuperUser | SYS

I wrote a step by step tutorial in the qewd-howtos repository how you can write state of the art multi-page web apps with Node.js using a QEWD-Up WebSocket/REST api back-end integrated with a mainstream web framework like NuxtJS & Vue.js.

Hi all,
We have a session values in a cache method and need to get those values in a client method (JavaScript).

Eg :
ClassMethod Method1()
{
Set %session.Data("Param1")="Data 1"
}

ClientMethod onloadHandler [Language = javascript]
{
var ret = zenPage.getSessionValues();
}

ClassMethod getSessionValues() As %String [zenMethod]
{
Set Data = $G(%session.Data("Param1"))
Quit Data
}

Hi guys,

It's FHIR contest and this time, they provided something really cool: FHIRaaS

And to be part of this, @José Roberto Pereira and I team up (again) to deliver something easy to use and easy to understand how we did.

An interesting thing about data is that we can always discover something new.

And with this concept in mind, we create a new page to show a little bit inside the world of ZPM!

Hey community,

I want to create my own table resizer. I know that there are some plugins that are doing exactly this but I would like to create my own one. :)

I have created a function, which is called in the onloadHandler and which append a div to each th-element of a given table. The method looks like this:

function initializeTableFeatures(){

This concept may be known to some, but I just found it very useful and I would like to share as it may help someone else.

If you are working with CSP or Zen you sometimes come across the need to use embedded JavaScript. Suppose you are working with some loops, which use < or > as shown in example below:

QEWD is assumed by most people to only integrate with IRIS (or Cache) via a connection through IRIS's high-performance C interface. This requires QEWD (and its Node.js environment) to be installed and configured on the same machine as IRIS.

I'm frequently asked if QEWD can run on a separate server (or servers), and access IRIS (or Cache) over a network connection. The answer is yes it can, but the information on how to set it up in this way has been admittedly a bit tricky to discover.
