#JavaScript

8

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.

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.

Can anyone share any examples?

Thanks

Hello,every body.

I am having a problem when using atelier. I found that the web front-end related files (such as csp, css, js, etc.) will change in format when they are synced to the server.

For example:

The original format of the js file may be UTF-8. However, when I edited and saved in atelier, the file version format on the server became ANSI. I tried to configure the environment in eclipse, but it doesn't seem to work.

E.g:

I cannot connect to Cache from node.js

I have installed in Windows 10 the following: CACHE 2016, node.js v 4.4.7 and express .

- where can I get cache.node? The link in the Intersystmes documentation http://globalsdb.org/downloads/ doesn't work. I found cache0100.node and cache0120.node in my Cache instance's \bin directory. But I am not sure if I can use them or not.

- how to install cache.node ? Where do I place it exactly?

Hi everyone, I have and Zen Mojo application, it's all working but I have some doubts about what is recommended to use: There is some reports of employees, for example, and actually I'm using some plugins : "Excelent export" to generate Excel reports and "jspdf" to generate PDF reports in client side.

I have an REST service, that receives the request, process and returns JSON, after client side receive the response it's processed.

- This can be slow/bad in applications with large data?

- It's better/recommended to use ZenReports even with ZenMojo applications?

Hi-

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

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.

Intersystems REGEX engine

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 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 -

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.node'

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:

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.:

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?

XData Style

{

<style type="text/css">

#loading {width: 100%;height: 100%;top: 0px;left: 0px;position: fixed;display: block; z-index: 99}

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?
