I am struggling in understanding how FDN works within Health Share, in particular those that are related to Provider Directory within Health Share. Does anyone have examples of using FDN that they would be able share?

Given the code below, I need help with getting the collected column widths from the Demo.Configuration table and stored in the columnWidths zne page property. As I understand it, I should be able to retrieve it using zenPage.columnWidths in the setColumnWidths or dgRender clientMethods but the alert is showing that it cannot be retrieved as it shows a value of Null. Once I can retrieve those values, then I want to set the widths of the colmns of the dynaGrid according to the values in the ^Demo.Configuration table. The data pulled in from the CSV file that creates ^Demo.

I am trying to use upload.csp as a template for choosing a CDV file to process. I am calling it from a zen page using this:
<button caption="Import Client Consultation Extract" 
       controlStyle="width:500px; height:100px; font-size:1.5em;"
         onclick="zenPage.importExtract();"/>

ClientMethod importExtract() [ Language = javascript ]
{
    // Open CSP popup to upload the CSV
    //alert('importExtract called.');
    zenPage.launchPopupWindow(zenLink('Upload.

Hi all,

I’m running into an issue with a %ZEN.Component.tablePane in a Zen page.

We have:

• A fully styled table with all columns defined
• A backend query (SearchMessages) that accepts multiple filter parameters
• A set of input fields at the top of the page for filtering (text, date, and checkboxes)

We’re trying to run the query from a button click using a client-side method (runSearch()) that collects the filter values, sets them as parameters, and calls executeQuery().

The problem is that the table does not update at all Old rows remain, or sometimes nothing appears.

Working on wrapping an IRIS Cache ObjectScript method that runs for a few seconds. Trying to get UI updates to show BEFORE the method runs in an async/await function. But it seems to be running synchronously rather than asynchronously . So my question is does IRIS/ObjectScript CSP pages support futures with JavaScript or does it run all synchronously.

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.:

• myFunction(params, callbackFunction(response))
• myFunction(params).

Hi everyone,

I'm working with JavaScript in InterSystems IRIS, specifically in CSP pages. One issue I'm running into during development is that the browser keeps loading the cached version of my JavaScript files, even after I’ve made changes or recompiled the code.
I would have to clear my cache files or browser history for it to reload and work.

Is there a recommended way or best practice in IRIS to automatically clear or bypass the browser cache for JavaScript?

I need to remove multiple languages from the language selection drop down which appears at top of Navigation app top bar. I need to keep only English.

Is there any way I can do that?

Or I can completly remove the language option?

Hello,

Our software commonly returns a full result set to the client and we use the DataTables plugin to display table data.  This has worked well, but at datasets grow larger, we are trying to move some of these requests server-side so the server handles the bulk of the work rather than the client.  This has had me scratching my head in so many ways.  

I'm hoping I can get a mix of general best practice advice but also maybe some IRIS specific ideas.

Hello, Does the NodeJs package work when running a node js file on windows (nodejs for windows)? I've added the package by running npm install <package location folder>

I have the following index.js file, but when running from node (windows) I get the following error. Does the NodeJs package build the output files when the package is added or does it just assume linux as the underlying os?

Error: Cannot find module './bin/winx64/irisnative.

Hi Community,

I have a CSP page I am developing with the intent of pulling files from an SFTP site and placing them in a folder on the local network.

I am having an issue where the CSP page is catching a JS error. The error in the browser is - A JavaScript exception was caught during execution of HyperEvent: SyntaxError: Unexpected identifier 'downloading'. (However, the unexpected identifier changes after refreshing page, or after removing the Write statement with the work 'downloading' in it.)

I think I have narrowed it down to a piece of the Javascript code - 

#server(..DownloadFiles(document

I am working on a product that uses REGEX and matches it. 
The regex is tested both on the client-side (using the JavaScript REGEX engine) and both on the server-side.
But I couldn't find one word about the way intersystems parses the regex, It is quite elementary to state which which engine it works with. 
from what I could gather from early implementations and such, the engine is based off PCRE, But I need to confirm this somehow, Can anyone give me a definitive answer, Is there any tool to test the regex other than writing it myself?

Hi:

I have been adapting the IRIS WHIZ addon as part of the contest. I will soon fork the code on github so the changes are available. 

The next phase is I am storing the date from and to time for a more complete search cache 

zenPage.getComponent(36).value

it works in the chrome console ok 

I'm not sure in external JS how to set the page it is on as a zenpage to use the zenpage functions

Hi, 

I almost managed to connect myself from nodejs to IRIS via intersystems-iris-native, but the connection failed. 

> const irisnative = require('./intersystems-iris-native')

{
  createConnection: [Function (anonymous)],
  Connection: [Function: Connection],
  Iris: [Function: Iris],
  Iterator: [Function: Iterator],
  IRISList: [Function: IRISList]
}

IRIS is known to have a built-in Python bridge and even allows you to write Python server code but what about JavaScript? Let's say I need a JavaScript expression interpreter. What would you recommend as the most effective way to get one? It is highly desirable that the solution does not require administrator privileges and uses in-process communication (I mean not http and not unix-specific interprocess-communication via command line)

I am trying to pull out something similar to an HL7 date/time stamp in a custom zen page , in a javascript code section.

var d = new Date();

(Fri Jan 12 2024 16:58:30 GMT-0500 (Eastern Standard Time)

but,
var year = d.getFullYear();

d.<formatcmd>  doesn't seem to work.  (d.getmonth, etc.)

Is there and date formatting I can use inside a javascript routine?

I wish to retrieve data from a cache table and then chart the results using javascript/chart.js.  I have had numerous iterations of the code attempting to do this (none of which worked) and my latest iteration is shown below.  

<html>
<head>
   <title>Cache Server Page</title>

   <!-- Include the Chart.js library -->
   <script src="chart.umd.min.js"></script>
   
<csp:SQLQUERY NAME='resultSet' P1='A'>
select Value, StatsDate from Stats 
</csp:SQLQUERY>

<script LANGUAGE="JavaScript">
// Initialize arrays to store data
var xValues = [];
var yValues = [];
</script>

Is it possible to get a code quality stamp of approval on the Open Exchange with an application written in Javascript?
My Iris Whiz application is a browser extension written in Javascript and I wonder if having the code quality stamp missing from my application page will put people off from using it.
 

I got a problem to resolve, to sum it up I need to extract a function body from a JS file with cos.
I already got the JS code in a string and the function name but I'm kinda stuck as to how to get my function body, I already tried a few things (regEx, counter bracket) but there are comment and strings that block them from functioning. Is there a javascript parser or a good way to do it except by creating a javascript parser?

I have created 3 pages, the scripts are there:

Class BZ.Test1 Extends %ZEN.Component.page
{
    ClientMethod onloadHandler() [ Language = javascript ]
    {
        console.log("Test1");
    }
}

Class BZ.Test2 Extends BZ.Test1
{
    ClientMethod onloadHandler() [ Language = javascript ]
    {
        this.invokeSuper('onloadHandler',arguments);
        console.log("Test2");
    }
}

Class BZ.Test3 Extends BZ.Test2
{
    ClientMethod onloadHandler() [ Language = javascript ]
    {
        this.invokeSuper('onloadHandler',arguments);
        console.

I have the following method call (have included html and css as well). when I debug the code in a browser, JavaScript seems to work fine. Loading image is coming up, table is getting hidden. But when I close the debug and just load the page and run it, loading image is not coming up, neither the table is hidden. Not sure what is going on? I need help to understand what I am doing wrong?

Hi Guys, I'm resending this because I sent on the weekend and looks like it has not been noticed much 

I'm not that familiar in using Javascript in Zen pages, so basically we have a priting utility (app) that requires us to add a bit of JavaScript call to facilitate printing from our Zen pages as below:

So I added XData link pasted the required script, is this the correct way?

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:

var FruitSelected=$('[name='Nameoftheradiobuttonhere]:checked').parent().

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.

Hi All,

Is there a way to include the build files (dist folder files after building vuejs) into a CSP page.

Thanks,

Hi,

I have been trying to implement SPA using routing between two components in a CSP page. 

If i use the line which i commented the page views and gets data from the vue instance (when not using the <route-view> and other 2 vue route functions below).

since i need to implement routing i am using as below, now the property "selectedYear" is not getting data from vue instane and i am getting the below error as well.

I dont know whether i am going down the right path.

please see my code below and help me

Does someone knows if any Studio version or, if in its new versions, it will be able to recognize new Javascript statements like arrow function, let, const etc ?

Hi All,

I have created a REST class in which have the Parameter HandleCorsRequest = 1;

I can able to access the API using Postman, but not with my web application. It throws the below error.

Access to XMLHttpRequest at 'http://localhost:52773/IrisVSCode/app/test' from origin 'null' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Please note that I have tried all option which are mentioned on following URL:

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
}

This is the code we implemented. But the problem is getSessionValues() method isn't called.
We need to know how to call a class method from client method.

Thanks,
Syed M

Does anyone know how to get the closing tab/menu changing event in a CSP? I've tried the JS "OnBeforeUnload" already but it seems the browsers aren't allowing it anymore. I need to show a pop-up that holds the user if trying to get away before completing the stage.
