But JScene is a proof of concept..It's not a completed product or reliable to be used in production.
We need a validated and proven open source which is active in development, so that we get proper support.
Can you suggest a working and proven library similar like JScene?

No.
I use Local Storage for storing JWT Auth Tokens and other small stuff such as program options, But have never considered using it for storing a database. The thought simply never occurred to me.
I see it different, because I as a user use my Desktop at work to shop, and my phone at home to purchase or vice versus.
I would not want to write a program in which the data was not available on both my devices.
But:
I am considering on my next shopping application written in a JavaScript framework like Angular to store cart content on the users device in cookies or perhaps Local Storage. To just use a JSON format and store the JSON text as a string. Perhaps a combination of both, in which the cookie says there is cart data and the data is in Local Storage. But this would break my rule unless I read the cookie, and if the user is logged in, I pickup the cart content and write it to their account document in MongoDB. I think EBay is doing this now.
But for you, what your doing is experimental as well and you seem to share the same idea with the JScene developer.
You would have to do a proof of concept in code and try them and see which works better. Just fill your concept with fake data but make sure you can store and retrieve.
[edit]
Not everything you can imagine has already been written and available as open source with support. Most web developers have never even heard of Local Storage, so the pool of choices for this will be very small. Your idea is an extreme concept.

jquery validation in Drop down..
if i am select the value another same div can't select this value..
and print the alerdy message "this value already selected"

There is no magic way to do it. You need to write code to do it.
Write code for the change event of the dropdown. Check if it's value is already selected. If so, display a message and reset the dropdown selected value.

I have created a dynamic drop-down list using JavaScript and I want the alert that is triggered on the screen after making the selections to say the wrestling level picked the wrestler name picked and the year in the alert and after that I want the JavaScript code to display an I-frame that contains a table of that wrestler's videos for that year. I somewhat understand the logic of the drop-down list but I don't know how to put the selections that I make on the list display in the alert such as the wrestling level picked the wrestler name picked and the year. Right now all the alert does is displays the final selection which is the year but I want all the selection information to be put into the alert. Secondly after this alert displays I want the JavaScript code to trigger the creation of an I-frame that displays a table with all the wrestler's videos for that year. I know how to create the table and information related with that but I can't seem to figure out the code to create an I-frame. As far as JavaScript goes I'm not very experienced and would be considered a beginner any help would be appreciated. The code I have is below.

Then you need to pass that information into the function that is creating the alert.

If you google javascript create iframe I'm sure you'll find a ton of examples. However, I would suggest instead using a div and using jqueryui to pop it up as a dialog.

I tried passing information into the function but when I try to make selections on the webpage it won't even let me select the wrestler or year. Here's my code.
function urlRedirectTo(wrestlinglevel, wrestlername, year)
{
alert('Here are all the wrestling videos for '+wrestlername ' ' +year ' ' +wrestlinglevel);
if('Varsity' == wrestlinglevel, 'Marc Hendricks' == wrestlername, '2013-2014' == year)

Does this code work?

It's your code so you need to change it so you can select what you need.

No my code isn't working and that's why I'm asking for assistance in making my code work I'm a newbie to javaScript and I've been stuck on this problem for over a week and I'm totally lost. I tried what you suggested and searched google but nothing I've seen looks like the issue I'm dealing with. I'm really desperate for guidance!!!

But the code you just showed was the code displaying the alert. You need to show the code that is calling that function. Why aren't you able to pass in the values? You said you could pass one value in so why not the rest of the values?
We're happy to help but I don't know where you are stuck or why.

I apologize I'm so lost. Here is my code attempting to pass values to the alert I know it's wrong just please let me know what's wrong with it.
function urlRedirectTo(wrestlinglevel, wrestlername, year)
{
alert('Here are all the wrestling videos for '+wrestlername ' ' +year ' ' +wrestlinglevel);
if('Varsity' == wrestlinglevel, 'Marc Hendricks' == wrestlername, '2013-2014' == year)
I'm not sure I'm even begging to pass values to the alert or if I'm doing nothing with the values.

This does not work like that. You cannot separate several conditions with a comma like you did. You have to use logical operators[^] to specify several conditions for a single if statement.
Maybe your intent was:
if ('Varsity' == wrestlinglevel && 'Marc Hendricks' == wrestlername && '2013-2014' == year)

Use your browser's console to debug this. For example, in Chrome hit F12 to open the developer console. Go to Sources and find your javascript. Right click the alert line and add a breakpoint. Then run your code and the debugger will stop on your breakpoint. At that point you can examine what values are in wrestlinglevel, wrestlername, and year. If they are all empty, that means you haven't passed them into the urlRedirectTo function so you need to back up further and see why you aren't getting what you thought you should when you call the function.

So I have this onSubmit function that gathers the data from the form.
Sometimes there is no sub category, or the subcategory has been removed and I haven't written code to update the product subcategory yet. Well I did write code for that but that's another story.
So below, this.model.SubCategoryId =
Then the next line will fail because there is no result with a Key
this.model.SubCategoryId = this.productForm.controls["subCategoryId"].value;
this.model.SubCategory = this.subCategories.find(sc => sc.Value === this.model.SubCategoryId).Key;
I wrote this, well found it on the internet
this.model.SubCategory = this.ensure(this.subCategories.find(sc => sc.Value === this.model.SubCategoryId)).Key;
ensure<T>(argument: T | undefined | null, message: string = "This value was promised to be there."): T {
if (argument === undefined || argument === null) {
throw new TypeError(message);
}
return argument;
}
I'd like to not throw an error, and return a blank string. Perhaps I'm going about this the wrong way.
One suggested using filter instead of find. I get what the function does, but T is fuzzy to me. Guess it's a generic type in TypeScript. The Type is KeyValue that I made. Perhaps I should change T to KeyValue and return a new KeyValue. hmm...

That worked. Guess I can get rid of the message or console.log it.
If you have a better idea let me know.
this.model.SubCategoryId = this.productForm.controls["subCategoryId"].value;
this.model.SubCategory = this.ensureKv(this.subCategories.find(sc => sc.Value === this.model.SubCategoryId)).Key;
ensureKv<T>(argument: KeyValue | undefined | null, message: string = "This value was promised to be there."): KeyValue {
if (argument === undefined || argument === null) {
argument = new KeyValue("", "");
}
return argument;
}

Closing brace on your function is missing. That would definitely cause a problem.
Also, .getElementById() wants a string parameter, sooo...
function colorchange() {
var dd1=document.getElementById('d1');
var dd2=document.getElementById('d2');
dd1.className ="blueback";
dd2.className ="yellowback";
}

Also, your CSS syntax is off:

background-color: lightblue;
}
.yellowback {

Hi all,
I have a
<div class="header-top-outer container-fluid"> , i have imported the css files where these classes exist into my project with a statement
import style from '../css/styles.css'
In my react component when I am trying to reference this div as below in my React component:
<div className={style.footer-outer + ' ' + style.container-fluid}>
it is throwing a compiled error for me:
./src/components/FooterMenu.jsx
Line 25: 'outer' is not defined no-undef
Line 25: 'fluid' is not defined no-undef
Line 26: 'outer' is not defined no-undef
Search for the keywords to learn more about each error.
What is the option to avoid these errors? Like what is the way I can reference css classes which have - in them using import reference?
i have tried the following way also, but it didn't work:
<div className={'${style.footer-outer} ${style.container-fluid}'} >

footer-outer is not a valid Javascript identifier. It will be interpreted as (styles.footer) - outer, where the variable outer has not been defined.
I've not used React, but it looks like the CSS loader has an option to convert "kebab-case" class names to "camelCase" identifiers:
GitHub - webpack-contrib/css-loader: CSS Loader[^]
That should let you use:
{style.footerOuter + ' ' + style.containerFluid}
If that doesn't work, try using the indexer on the style object:
{style['footer-outer'] + ' ' + style['container-fluid']}

Hi i am trying, but facing huge difficulties in converting a jQuery MVC app into React Web Api app, can somebody please help me, I though I can easily take all that's there in the convert easily into React but, i have come across lots of difficulties, one such is, importing css styles, and referring multiple css classes (in jQuery they can put multiple css classes in one element, but I am not able to do it in jsx files).
Now I am just thinking, can i just put all those js files into a folder just reference them into my jsx files or components, can somebody please help me in this regards? How can I do it and what difficulties am I going to face, how can I call those methods within js files of jQuery into my jsx components, any help please - I would be very very thankful friends.
I am also trying in my way by googling, reading online, asking friends and colleagues - but if anybody has faced these issues before could be helpful for me - thank you
