HTML-Forms

Here is the problem: I want to make an HTML form in a local file(as a sort of UI), and then save data from that form into a JSON file(preferably, other file types are OK as well). I assume a JavaScript is needed in the HTML to do something with the form. From another thread(How to use HTML forms without a server), I heard about a $_GET function, but it was not clearly explained and didn't work when I copied the example code into an HTML editor. It was also missing the explanation for how to write it to a file, probably because JS on the web can't write a file on your client computer. In this scenario, however, my goal is to have the entire thing stay local. This was one of the solutions presented by the other thread:

I am working on AWS Sagemaker and my goal is to follow this tutorial from Pytorch's official documentation.

I'm new to Razor but experienced in classic html and C#.

For the beginning I have done the razor tutorial from Microsoft. After doing it I wanted to play with the code and so I got my question.

I want to make the view-code more dynamic by creating the html by reflection (this view-code I mean). In future I want to generate whole html-forms by a model without the need to write html.

There are property blocks like this two examples (Title and Release Date):

When I use Chrome on Android to fill a web form, by pressing the blue "enter" button the browser auto focuses on the next text field. How can I prevent this from happening?

Good day to all, I am new to Laravel framework and as I read some articles about HTTP verbs which say that POST is universal to both PUT and DELETE (reference:

https://softwareengineering.stackexchange.com/questions/114156/why-are-there-are-no-put-and-delete-methods-on-html-forms

) and thus I wonder if it is possible to achieve Update and Delete functionality with POST and without using hidden() in the view itself. For example, if you look at the code below hidden method is used to clarify which HTTP verb should be used in this case PUT and what if I remove it and try to update the data will it be possible. The code:

I was looking for a way to take input from my HTML form to my javascript code without a server inbetween and found this post on Stackoverflow: How to use HTML forms without a server

There, the first answer included the following link to a code example on js.fiddle: http://jsfiddle.net/wG8K4/1/

An inexperienced web developer crying out for help!

Introduction

I am developing an MVC web app (using ASP.NET Core due to my interest in it). In the back-end, there is an MSSQL Server with quite sophisticated Databases (thousands of tables). In my project, I'd like to present part of the public data in the View (in Tables), based on the user's queries (sending Form requests) and later allowing the user to download the data (CSV, XML).

Architecture challenges

• Data Access Layer

First I started with using Entity Framework but later realized that simply can't translate all my SQL statements to LINQ. The reason is the simplest query contains several INNER JOINS and LEFT JOINS and SELECT statements and an endless number of Tables.

• Business Logic Layer

I am planning to build a REST API, sending the data in JSON format. As far as I concerned in .NET Core MVC I can have my API Controller in the same project as my presentation layer.

• Presentation Layer

This is the only part I have experience with, building web apps using MVC 5.

The big struggle

In this project, I will not manipulate the data, only READ it and present them to the user. I am aware the guidelines of using different Model class (Domain, Entity, ViewModel)

What I do now, and I suppose it's wrong:

• The MVC's API Controller returns the SQL query results as type DataTable object (have an SQL Helper class to do the job), so far my controller takes care of serializing the objects as JSON.

• Another Controller (with model binding from the view) gets the user search criteria via HTML-forms and calls the API Controller with binding the corresponding properties.

The questions finally

• Am I supposed to stick to raw SQL queries instead of Entity Framework, and if so, shall I use simply separated class libraries (as Data Access Layer) and reference it in the API? Or leave out the DAL and put all the SQL query logic into the API?
• Does one need to use Entity Framework in case of only reading the Data without manipulating it? The only manipulation I intend to do is to format the look-and-feel in the logic layer.

UPDATE EDIT:

In my SQL queries, I must create temporary tables which are not supported in LINQ. Any suggestions?

In case this question will be marked as an architectural and not a programming one, please accept my apologies and kindly refer me to the right forum where I could get help.

Many thanks in advance!

I am working on a webscraping project to download various csv files from this webpage: https://whalewisdom.com/filer/blue-harbour-group-lp#/tabholdings_tab_link

I would like to be able to programmatically choose the various reported quarters on the drop down list, hit submit (note that the URL for the page doesnt change for each different quarter) and then "Download CSV" for each of the quarters.

As a disclaimer, I am a novice to rvest and below is my attempt at the solution:

1. I first checked this site and found a relevant post Using r to navigate and scrape a webpage with drop down html forms

2. It looks like they use the following code to get a form for what the inputs need to be to refresh an HTML table:

I would like to scrape the historical weather data from this page http://www.weather.gov.sg/climate-historical-daily.

I am using the code given in this link Using r to navigate and scrape a webpage with drop down html forms.

However, I am not able to get the data probably due to change in structure of the page. In the code from the above link pgform <-html_form(pgsession)[[3]] was used to change the values of the form. I was not able to find a similar form in my case.
