JavaScript, often abbreviated as JS, is a high-level, interpreted programming language. It is a language which is also characterized as dynamic, weakly typed, prototype-based and multi-paradigm.
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 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.
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?
In response to the infrastructure needs of our company's service, I've created a small API that sends SNMP queries to InterSystems to visualize relevant data for retrieval when the infrastructure implements monitoring.
However, I'm experiencing a timeout issue when attempting to collect information using an SNMP walk. Here is the code for my API's SNMP service:
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?
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.:
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 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).

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 ?
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.
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:
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.
I am trying to set a varaible/property within JavaScript and use the value in my method. The alert method below returns "0". Do I have the syntax wrong?
I am trying to create a simple example of allowing binary (tiff) files to be selected and uploaded asynchronously to an IRIS for Health back-end. I have managed to write the HTML and Javascript which works great with regular text / ascii files, but fails with binary files.
When I upload a binary file (tiff) image I get garbage like this on the database server
I recently added a change to our copy of zenutils.js, and while moving it up to production, I found different versions of zenutils.js. I edited a copy stored in the default directory for our web application (e.g. c:\intersystems\DEV\CSP\{application}) but the file on production is stored in {install dir}\CSP\broker.
I have a query that I would like to have refreshing at certain intervals lets say every 30 seconds with out refreshing the page content using the META TAGS

Has anyone called any outside Javascript code from inside their class files? I asked a long time ago if there was a way to manipulate an image within Cache Object Script, and since Cache doesn't have any image libraries its not really possible. However I have found Javascript to resize an image and wonder how hard it would be to mesh the two together.
