Why Javascript code does not execute anymore after I put it inside function - onclick event?

var Crypt = new Crypt(); <----- ERROR
Crypt = name error
Try it
var Cryptx or var Cryptxx or var Cryptxx or
ex.)
var Cryptxx = new Crypt(); // constructor
/*** encrypt */
var ciphertext = Cryptxx.AES.encrypt("plaintext");
// XluzvcUwZFU=3MD2vMz8PHySPJlKZiWjJg==1Gv6n6Tv8azr
/*** decrypt */
var plaintext = Cryptxx.AES.decrypt(ciphertext);

You are declaring a variable called Crypt and then trying to use the same name in your new clause. Which is the variable and which is the class? Use a different name for the variable.

Do you want to try that again, this time telling us what the actual problem is?
Include the full details of any errors, and tell us which line of code they relate to.
And explain where the undefined Javascript variable tbl_GetAllModule comes from, and where the non-standard .ajax.url(...).load() is declared.

Good day. hope someone can give me some advice.
i am quite new to HTML5 and Jscript. i am just trying a very standard webpage where i want someone to enter a name, surname , and age for example via a HTML form (which i can easily create).
However i am struggling to find anything on the web to teach me how to use Jscript to enter those fields into a database and retrieve it later if i need to.
Is it even possible or must i use something like NODE.js
maybe if someone can even point me to a beginners tutorial.
thanks in advance:

I like to "do it right" and use a php back-end. This will give you other advantages down the line, such as the ability to invoke AJAX to update parts of pages and execute SQL without a page refresh, and of course the ability customize pages on the server side.
It's somewhat similar to JavaScript it syntax as both use the "C" like style. PHP runs purely on the server, before the page gets sent. You'll be able to work magic with ease.
Tutorials that work (and are free!):
JavaScript[^] PHP[^]
They also have SQL, CSS, and you really aught to learn DOM, a part of javaScript that really makes it all worth it. Not as big an undertaking as it sounds.

Hello to all
I'm using knockoutjs for my new project.
I ask you for advice on the most suitable choice for the grill
I tried to use KOGrid, very useful but with some problem (in my opinion) on the graphic aspect (non-responsive)
Do you have any suggestions?
Which grid do you use?
Thank you

Perhaps you should consider a library that provides support for such controls. I think most community based platforms do provide these controls — DevExpress, Kendu etc.
Anyways, take a look at this GitHub repository: https://github.com/dnbard/awesome-knockout, there is a list of the controls that are supported for Knockout.

I am a total beginner to programming. I want to start with javascript, but there is a problem. My laptop has stopped working and all I have is my smartphone. I still want to learn programming and it will be a while before I get a laptop/pc. Can you suggest ways to learn programming through apps/online, or I am willing to read books as well. What would be the best way to approach this situation Thanks alot

You can practice js etc using JSFiddle[^] Not sure how well it will work through a smart-phone, and obviously it'll be much harder than with a laptop but probably your best option. I'd also look to see if there was a library or school or some other public institution that had a PC I could use.

This is the code of a hex board game.In this game there are two players RED(user) and BLUE(bot). The one who reaches the opposite end and creates the link without any other color interrupt that player wins.In this game every time RED(user) wins most of the times which is the problem. I want BLUE(not) to be more intelligent by developing its own intelligent decision tree and the chances of RED(user) to be reduced to 10%. Can anyone help me improving my code?

It has been 12 days since you asked this question here. This is why we have QA sections, to ask programming questions. Please ask a question rather than posting on a discussion forum.

The question is just as valid here as in QA.

Not really, since we have no idea what all that code is supposed to do. And, yes, I know you gave an outline of your program above, but it would still take quite a lot of work to fully understand it. These forums are to answer specific technical questions, not to critique people's work; basically people here do not have the time to do such things.
