Screen Shots of simple Interest

Re: Mobile Technology: Lets Build A Mobile App With Javascript by Lordpeckxy(m): 7:45am On Sep 30, 2019

The Idea Is Start small, Grow Big...
Learning How to Manipulate simple programs will make you more proficient in designing a more stable application....
Example with a Simple Interest Calculator you the capability to develop a compound Interest, Tax deductor, Estimator, which gives you the Knowledge to build a government app...
.
Right on this platform, We will Implement a Governmental App that will perform various activities, study the simple Interest, Improve and Upload it for review...
Next you can go for compound Interest and different fianacial calculations....
.
Am going to upload a Grade Calculator Both the working and source-Program,
don't forget, start small, understand the Twerks and Grow Big...

I Once wrote this Program, when i first Started JavaScript....
Haa and Since then Its Been A Bumpy Ride...
.
If you want the source code of this program, Just download It Into your Files Manager, and ensure the Name still Remains GradeSoftware.HTML don't forget The .HTML extention.....
.
Look the content of the code, Its quite simple.[No comments though]

Your Code Is buggy...
Don't just try and copy paste all the codes to your editor, try to understand what they do, and if possible comment on it...

It very well depends on the Device you are using for coding, I Like to use Sublime Text when am coding on my Pc and Anwriter when am tasting It on my android device, and often I mostly screen shots my android program... I once Told you Guys that a basic Knowledge Background on HTML, CSS and JavaScript Is Recommended, if that Knowledge was present It would be quite easy to define the markup.... . . . Anyway Just wrap up this <p> </p>(Paragraph) tag on each Input... Example

<p> <input type="text" id="txt1" placeholder="Principal" >
</p>

<p> <input type="text" id="txt2" placeholder="Rate" > </p>

<p> <input type="text" id="txt3" placeholder="Time" > </p>


<!-- The paragraph tag causes each Input to be on a New line -->

I don't think you Guys are ready 4 any real Life application, because Most of you dnt do you Homework, I told you back then to learn the basic of HTML, CSS and JavaScript, No you didn't Learn it and now you are complicating things.
We won't Move faster at this Rate. If you dnt know the basics of these Language, How can you Understand, Create and Improve Programs...
If you have an android device, Please Download the Sololearn app from Google Playstore,If you already familiar with it, well it won't hurt to refresh that Knowledge, If you dnt, then start from HTML, Progress through Css and then to javascript, dnt complicate things for you and I...

I call It MATH PRODIGY...
First UI design of MATH PRODIGY coming By 10:30pm today...

And we enter a New one.!!!
Stay Tune.!!!
Re: Mobile Technology: Lets Build A Mobile App With Javascript by Lordpeckxy(m): 7:25am On Oct 04, 2019

[JS]
Now Before you Start coding...
Follow these steps...



* Create an empty folder and name it Math_Prodigy

* In these Folder, that where all the documents, files, and Program will be stored...

* Any Picture I use on the cause of writing the App, i will Upload in this forumn, or better still use yours for a different feel.!

* Anytime we are developing a new app, use this approach.!!

* In this app we are creating, we will be using external Js and likewise CSS and If they are not in the same directory, it won't or can't be accessed.

* so create your folder cause the first Markup experience is coming

@Lordpeckxy , I just stumbled on this thread. It's an amazing job you're doing here. I've bookmarked this thread already. Gladly awaiting your next update.
Re: Mobile Technology: Lets Build A Mobile App With Javascript by Lordpeckxy(m): 2:57am On Oct 07, 2019

Am Been slow --- Yes.
.
But It is a Gradual Process...

*Am posting the first Markup, If you don't understand any coding Lines(thou there are comments) tell me...

* I really don't know and still learning how to design an interface that can adapt to both desktop and mobile view, but since its a mobile app, i won't go into that branch of designing for Desktop...

* For a better Mobile webview experience, I recommend you download anWRITER in google playstore.!!

* Using a Laptop: Customize each codes to fit the required width and size of the laptop screen.!!

* G.U.I coming up.
