WeatherAPP | 这是一款带有段子加平台分享的天气预报APP

I am writing simple JS app that shows weather. After first query variables like searchTerm or every variable from array are appends to the specific element. But after another query they are not override but added next to the previous one. How can i fix that? Should I use innerHTML or just refresh the page after another API call?

I created a WeatherApp Component using React in VSCode IDE.

However, I mispelled WeatherApp below, adding in extra/text digits. How can I get VSCode to display mispelled components?

I have ESLint and ReactCodeJS snippets extensions installed. Its giving a compilation error at command prompt, however no red underlined text is showing in IDE. How can have it displayed as error/warning in VSCode?

I am trying to run the webAPI (C#) in Visual Studio 2019 and test in Postman. These are steps I took

1. Created a new project with type WebAPI in Visual Studio 2019 (selected C#) with example controller (WeatherApp)
2. Ran the application in Visual Studio 2019. It opens the browser and brings up the url as http://localhost:62002/weatherforecast the application then immediately shutsdown
3. I have postman window open, where I would like to test the api, but I am unable to.

I am trying to setup the environment, so that I can create my new webapi with get/post requests and run from postman, while debugging from visual studio 2019

Am I doing something wrong here ?

I'm trying to dispatch inputValue from my searchingBar to my initialState in reducer. When I try to push it to my state, i get that updateValue is undefined.

My reducer:

I am very new to reactjs and I was making my second project on Weather Forcast APP. In which I am getting error whenever I wanted to get the data that is stored in weatherList. it is howint that " TypeError: Cannot read property '0' of undefined dataExtracting ".

Please Help me with right suggestions that I should use to avoid this error.

Following is my App.js Code :-

Thanks in advance for any help you can give me. As mentioned in the title, I'm attempting to fight my way through an intro course and I'm struggling pretty hard with this particular issue.

HERE IS WHAT I NEED TO DO:

"Now we can start using APIs to get information from others applications. Lets create a Weather app like this one.

this project consist on create an app that takes the name of any city via input and display the current weather and the weather for the next 7 days.

The main point of this project is learn how to get info from the API and handle multiple promises.

You will get the input value (city name) from the element with the 'id=city' in the index.html file.

Each time the user clicks the 'search' button the program has to get the city name from the input (validation is required) and make the API call. Write all the javascript code in 'weather.js' file.

You need to create an account in OpenWeather and then you will be able to get an API KEY how to start with OpenWeather API

OpenWeather has differents API calls. You can see all the options here

We are using two of those:

• Current weather data
• One Call API

All right first things first. You are going to create a re-useful fetch function to get data form the API

The first API call (current weather data) is getting a response with the current weather for an specific city name (lets use the option By city name). The response also contains the latitude (lat) and longitude (lon) things that you will need for the next API call."

HERE'S WHAT I'VE DONE:

I am working on a project with python, and I need my main page to be scrollable, but it doesn't work... I've tried like literally everything. Here's my code:

main.py

In my login page, whenever I create a class object of User (which is necessary to access its properties), the app crashes.

My Login page code:

I have the following ContentPage ("LoginPage") which among others prompts the user for his username and password:
