here are many algorithms that are used to solve variety of problems. In this part you should
write an algorithm that shuffles a given array, the shuffled array should be completely different
than the given array, explain your chosen algorithm, describe the algorithm steps in pseudo code

I want to have active menu items in my navigation based on URL and ID, not href. None of the available solutions (this one, this one , or this one) worked for me.

My Navigation looks like this

<nav id="PageNavigation">
    <div class="nav_ebene_2">
        <div role="button" class="nav-item" id="P_Bogendaten.aspx?IDNavi=194">
            <p>menu item 1</p>
        </div>
    </div>
</nav>

The URL, if clicked on menu item 1, is https://example.de/App_AspxFiles/P_Bogendaten.aspx?IDNavi=194. I want to add the class menuactive to the parent element (div which includes nav_ebene_2)

I need to compare the id with the current url, if it matches, add menuactive. This would be my way, but the if conditions is never true.

  var currenturl  = window.location.href
  for (const div of document.querySelectorAll("#PageNavigation nav-item")) {
    if (div.id == currenturl ) {
      div.parentElement.classList.add("activemenu");
    }
  }

Thank you very much!

I have a question I am currently upgrading my Discord bot to DISCORD JS V13. Now I’m trying to get the Chanel ID of certain Chanels, but I keep getting undifiend or 0 back. I’ve already tried to rewrite my old code from the DISCORD JS V12, but it doesn’t work. There is also not much online about DISCORD JS V13.

const path = require("path");
const fs = require('fs');
const {
    Client,
    Intents,
    Collection
} = require('discord.js');
require("dotenv").config();

const client = new Client({
    intents: [Intents.FLAGS.GUILDS]
})
const functions = fs.readdirSync("./src/functions").filter(file => file.endsWith(".js"));
const eventFiles = fs.readdirSync("./src/events").filter(file => file.endsWith(".js"));
const commandFiles = fs.readdirSync("./src/commands").filter(file => file.endsWith(".js"));

client.commands = new Collection();
client.buttons = new Collection();

(async () => {
    for (file of functions) {
        require(./functions/${file})(client);
    }

    client.handleEvents(eventFiles, "./src/events");
    client.handleCommands(commandFiles, "./src/commands");
    client.handleButtons();
    client.login(process.env.BOT_TOKEN);
    const connection = client.dbLogin();
    console.log(await client.channels);
    client.channels.fetch('691022255098036375')
        .then(channel => console.log(channel.name))
        .catch(console.error);
    console.log(await client.channels.cache.get("691022255098036375")); //undefined
    //client.joinHome();
})();

I have a select in which the checkbox is located, it also contains an input through which I want to find the necessary items. I did the search like this, first I accept an array and then lowercase it and search for matches. Somehow I need to match the required id to exclude unavailable ones and display the necessary checkboxes

In simple terms, I want to filter my query and display it in real time.

I must use only vanila JS

let search = document.getElementById("search"); 
let s = document.querySelectorAll("input[type=checkbox][name=one]");

//s.forEach((item) => {
search.addEventListener("input", () => {
  let data = [];
  
  let count = Array.from(s).map((i) =>  i.value.toLowerCase().includes(search.value.toLowerCase())
  );

  console.log(count);
  
});
//});

<div id="checkboxes2">
        <div class="control">
          <input
            class="input"
            type="text"

I’m trying to horizontal scroll the table not with the scrolling bar, but with the mouse inside the table just like its done with a touch screen. Does anyone know if its possible to do this without a plugin? To make the table horizontally “draggable” just for scrolling?

Ps.: I know that the snippet below does what I want in mobile mode, but I want to achieve that with the mouse.

.container {
  width: 30em;
  overflow-x: auto;
  white-space: nowrap;
}

<div class="container">
  <table>
    <tbody>
      <tr>
        <td>Image 1</td>
        <td>Image 2</td>
        <td>Image 3</td>
        <td>Image 4</td>
        <td>Image 5</td>
        <td>Image 6</td>
        <td>Image 1</td>
        <td>Image 2</td>
        <td>Image 3</td>
        <td>Image 4</td>
        <td>Image 5</td>
        <td>Image 6</td>
      </tr>
      <tr>
        <td>Image 1</td>
        <td>Image 2</td>
        <td>Image 3</td>
        <td>Image 4</td>
        <td>Image 5</td>
        <td>Image 6</td>
        <td>Image 1</td>
        <td>Image 2</td>
        <td>Image 3</td>
        <td>Image 4</td>
        <td>Image 5</td>
        <td>Image 6</td>
      </tr>
    </tbody>
  </table>

I have multiple buttons that can be clicked by mousedown/touchstart, after 2 seconds, you get a popup to make sure, and you can click “yes” or “no”.

The issue comes when you click one, then select “no” and click another one. When logging the “data-id”, the first one clicked is the one passed, instead of the clicked one.

I thought this was an event.preventDefault(), event.stopImmediatePropagation issue, but this is not helping me at all, I don’t know what else to try anymore or know WHY this is happening.

Here’s a preview of the JS file:

$('.btn').on('mousedown touchstart', function (e) {
    e.preventDefault();
    e.stopImmediatePropagation();
    let button = $(this);
    console.log('Before setTimeOut: ', button.attr('data-treatment-id'));
    
    timer = setTimeout(async function() {
    $('#make-sure-location').show();
    
    $('#not-in').on('click', function(e) {
      console.log('not in location: ', button.attr('data-treatment-id'));
      e.preventDefault();
      e.stopImmediatePropagation();
      $('#make-sure-location').hide();
      clearTimeout();
    });

    $('#inside').on('click', function(e) {
      console.log('on location: ', button.attr('data-treatment-id'));
      e.preventDefault();
      e.stopImmediatePropagation();
    });
    
  }, 2000)
})

Here’s a working fddle:
https://jsfiddle.net/rj8ofLym/28/

To recreate issue:

1. MouseDown first button
2. Click “No” on div.
3. Check logs (correct “data-id”)
4. MouseDown second button
5. Click “No” on div.
6. Check logs (INcorrect “data-id” – still first one)

Till now I was redirecting to the User Dashboard from the React component, but I want to apply a different approach, I want to redirect after getting the success response from the saga itself.

For this, I have attempted to use redux-first-history (which comes with the support of react-router6) I have followed their documentation, almost everything is working but an action @@router/CALL_HISTORY_METHOD getting called twice.

Here are my routes

export default function App() {
  return (
    <AuthProvider>
      <Router history={history}>
        <Routes>
          <Route element={<Layout />}>
            <Route path="/" element={<PublicPage />} />
            <Route path="/login" element={<LoginPage />} />
            <Route
              path="/protected"
              element={
                <RequireAuth>
                  <ProtectedPage />
                </RequireAuth>
              }
            />
          </Route>
        </Routes>
      </Router>
    </AuthProvider>
  );
}

which goes across the project, below is my store.

import { applyMiddleware, compose, createStore } from "redux";
import { persistReducer, persistStore } from "redux-persist";
import storage from "redux-persist/lib/storage";
import createSagaMiddleware from "redux-saga";
import rootReducer from "../store/reducers";
import { watchAuth } from "../store/sagas/index";
import { createReduxHistoryContext } from "redux-first-history";
import { createBrowserHistory } from "history";

const composeEnhancers =
  process.env.NODE_ENV === "development"
    ? window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__
    : null || compose;

const { createReduxHistory, routerMiddleware } = createReduxHistoryContext({
  history: createBrowserHistory(),
  oldLocationChangePayload: true,
  showHistoryAction: true,
});
const sagaMiddleware = createSagaMiddleware();
const middleware = [sagaMiddleware, routerMiddleware];
const persistConfig = {
  key: "root",
  storage,
  whitelist: ["auth"],
};

const persistedReducer = persistReducer(persistConfig, rootReducer);

export const store = createStore(
  persistedReducer,
  composeEnhancers(applyMiddleware(...middleware)),
);
const persistor = persistStore(store);
sagaMiddleware.run(watchAuth);

export const history = createReduxHistory(store);
export default store;
export { persistor };

and my Saga

import { call, delay, put } from "redux-saga/effects";
import axios from "../../../config/axios";
import {
  authFail,
  authStart,
  authSuccess,
  checkAuthTimeout,
  logout,
  logoutSucceed,
  setAlert,
} from "../../actions/auth/auth";
import { LOGIN_API } from "../../apiCollecitions";
import { push } from "redux-first-history";

export function* authLoginSaga(action) {
  yield put(authStart());

  const authData = {
    email: action.email,
    password: action.password,
  };
  try {
    const response = yield axios.post(
      `${LOGIN_API}?lng=${localStorage.getItem("i18nextLng")}&active=true`,
      authData,
    );
    yield localStorage.setItem("token", response.data.token);
    yield localStorage.setItem("expirationDate", expirationDate);
    yield put(authSuccess(response.data.token));
    yield put(push("/protected")); //should redirect to the specified route
  } catch (error) {
    yield put(authFail(error.response.data.message));
  }
}

I have also set up a sample GitHub repo for the same, for your reference.

Good afternoon everyone!

I’m stuck since 3 days searching answers in forums and here also, and i can’t solve it.. Maybe you can help about this problem:

In javascript is easier, but in NUXT we can’t insert Javascript where we wan’t..

In the component page:

<script>
  async fetch() {
      this.ArraySkills= await fetch(`https://api.test/player/${id}`
      ).then((res) => res.json ())
      
    },
    data () {
      return {
        ArraySkills: []
      }
    }
</script>

This url is a test. But it’s return an array about skills of player 1. I already display the skills of this player.

But i need to display the forEach players, their skills (40 players).

I created an ArraySkills. And i would like to visit the url1, url2, url3 etc.. And to push() inside the ArraySkills

In pure JS i would done :

let id=1
while (id<41) {
 id++;
  async fetch() {
      this.ArraySkill= await fetch(`https://api.test/player/${id}`
      ).then((res) => res.json ())

    },

   ArraySkills.push(ArraySkill);

}
#And then he will fill the ArraySkills with the 40 players

But in Nuxt it's seems harder :/

I have just recently switched to React navigation v6 in my RN app and I can’t seem to understand why my Button(s) and Touchable(s) do not recognize onPress function the second time they are being pushed.

The scenario:

1. I launch Home Screen.
2. Press go to test screen button. The console prints the message.
3. On Test Screen press go back. The console prints the message. I go back.
4. Back on the Home Screen the button doesn’t work anymore. Console does not print the message

Home.tsx

<View style={{ flex: 1, paddingTop: 30 }}>
      <Button
        title='go to test screen'
        onPress={() => {
          console.log('pressed to test');
          navigate(TEST_SCREEN);
        }}
      />
</View>

TestScreen.tsx

<View style={{flex: 1, paddingTop: 30}}>
   <Button
     title='go back'
     onPress={() => {
       console.log('pressed go back');
       goBack();
     }}
   />
</View>

navigate func:

export function navigate(name: string, params?: any | undefined) {
  if (navigationRef.isReady()) {
    navigationRef.navigate(name, params);
  }
}

navigator:

const Home = createStackNavigator();

export default function HomeNavigator(): JSX.Element {
  return (
    <Home.Navigator
      initialRouteName={HOME_SCREEN}
      screenOptions={{ headerShown: false }}
    >
      <Home.Screen name={HOME_SCREEN} component={HomeScreen} />
      <Home.Screen name={TEST_SCREEN} component={TestScreen} />
    </Home.Navigator>
  );
}

routes:

export const HOME_SCREEN = 'Home';
export const TEST_SCREEN = 'Test';

I have an image that was readed to javascript.

I used sublime text to see the image and it is like this:

I readed this image and generate javscript arrayBuffer of Uint8Array

Inside this arrayBuffer, i see also ffd8 ffe0 like in photo above.

Now, i need to downlaod it to local machine, i used

 var blob1 = new Blob([byteArray], {type: 'application/octet-stream'});
                var fileName1 = "cool.bin";
                function saveAs(blob, fileName) {

    var url = window.URL.createObjectURL(blob);
    var anchorElem = document.createElement("a");
    anchorElem.href = url;
    anchorElem.download = fileName;
    anchorElem.style = 'display: none';

    document.body.appendChild(anchorElem);
    anchorElem.click();

    document.body.removeChild(anchorElem);

    // On Edge, revokeObjectURL should be called only after
    // a.click() has completed, atleast on EdgeHTML 15.15048
    setTimeout(function() {
        window.URL.revokeObjectURL(url);
    }, 1000);
}

After i downlaoded this image from javascript,
I see in sublime text diffrent bytes

What worng with my javascript donwload code ?

I am scaffolding a simple prototype using google places and maps api using Vue.

In index.html, I added the script tag, libraries, and api key, I get 200 response in the network tab.

        <script src="https://maps.googleapis.com/maps/api/js?key=My-api-key&libraries=places" async defer></script>

In App.vue, I added the following

 <input ref="autocomplete" type="text" />
 ...
<script>
  export default {
  name: "App",
  data() {
   return {
     autocomplete: "",
    };
  },
  methods: {},
  mounted() {
    const center = { lat: 40.84498856765032, lng: -73.71060855293794 };
    // Create a bounding box with sides ~10km away from the center point
    const defaultBounds = {
    north: center.lat + 0.1,
    south: center.lat - 0.1,
    east: center.lng + 0.1,
    west: center.lng - 0.1,
  };
  const originAutoComplete = google.maps.places.AutoComplete(
    this.$refs["autocomplete"],
   {
     bounds: defaultBounds,
   }
 );
 originAutoComplete.addListener("place_changed", () => {
   console.log(originAutoComplete.getPlace());
 });

How do I resolve this error? Is there a way to initialize this in App.vue script tag? The example google developers youtube works great, but I’d like to implement this in a Vue context.
One other note, I tried adding window before the .google, no dice.

I can’t seem to figure out how to do the object part, I need to make it calculate the age dynamically. I’ve written most of the stuff here and it works fine the only down side is my dynamic age calculation, I don’t know what I’m doing wrong and can’t find my mistake.

I need to be able to have a background music for my weather app that I am making in javascript. I I am not familiar with python and I wanted to see if anyone can translate it for me. It would be kindly appreciated. It is the only weather based music api that I have come across after researching for some time now.

I’m drawing a grid on a JavaScript canvas on this canvas I also have a moving element so the Grid can be on/off with a button all is well apart from the speed of the moving element when grid is on it becomes extremely slow. I’m not really sure where am I going wrong. Can someone please give me some help. Thank you
