I want to replace the tag element with something else if possible in such a way to be able to keep the redux store. I tried Link or NavLink but it is not working. I want to keep the redux store without a persistent feature.
My app works fine on all screens without a persistent store but when I click on a tag the store is deleted and I have to login back.

I want to show YouTube settings menu with custom button, how can i do that?

chrome.runtime.onMessage.addListener((obj, sender, response) => {
const { type, value, videoId } = obj;

if (type === 'UPPER') {
  const upper = document.querySelector('.ytp-settings-menu');
  upper.style.removeProperty('display');
}

});

I create a form validation for my app. Now I test it for mobile devices. There is form with several fields and a “Submit” button below. When I click the button and the required field is empty, field.focus() method invoked. Focus causes scrolling to the field by design. It works fine on android devices on any browser, but there’s no scroll to field on ios browsers (safari and chrome as well), only when I already focused on this field. When field was not focused originally, it works fine.

There’s a picture to better understand the problem

1. Tap on ‘name’ field

2. Keyboard opens so field goes beyond view

3. Tap on ‘submit’ and app call field.focus()

4. I expect view scroll to ‘name’ field (that’s how .focus() should work and it work on android or desktop, but not in ios) but it doesn’t happen

I tried to call field.scrollIntoView(), but it cancells field.focus(). I cant find a way to make them works together

What should I do?

Thank you in advance!

The code starts as follows

This code to define the table if possible can you give me a reference to the html code. Thank you

const BLACK = 'black'
const WHITE = 'white'
const PREVIOUS = 'previous'
const L = 'l'
const O = 'o'


let previousStone

let boardState = [
    L, L, L, L, L, L, L, L, L, O, O, O, O, O, O, O, O, O,
    L, L, L, L, L, L, L, L, L, O, O, O, O, O, O, O, O, O,
    L, L, L, L, L, L, L, L, L, O, O, O, O, O, O, O, O, O,
    L, L, L, L, L, L, L, L, L, O, O, O, O, O, O, O, O, O,
    L, L, L, L, L, L, L, L, L, O, O, O, O, O, O, O, O, O,
    L, L, L, L, L, L, L, L, L, O, O, O, O, O, O, O, O, O,
    L, L, L, L, L, L, L, L, L, O, O, O, O, O, O, O, O, O,
    L, L, L, L, L, L, L, L, L, O, O, O, O, O, O, O, O, O,
    L, L, L, L, L, L, L, L, L, O, O, O, O, O, O, O, O, O,
]

I tried the code and Ai doesn’t work when running with html

I would like to create a search bar where I can write the name of a city inside and see the quality of life data.
I know how to create the search bar but I don’t know how to connect everything to the Teleport API. https://api.teleport.org/api/cities/?search={city_name}.
All this with javascript, do you have any suggestions?

The function of JavaScript to link everything

I’m getting this error while trying to connect to mongoose.

/home/runner/SkrivInBussar/node_modules/mongoose/lib/connection.js:755
    err = new ServerSelectionError();
          ^

MongooseServerSelectionError: Could not connect to any servers in your MongoDB Atlas cluster. One common reason is that you're trying to access the database from an IP that isn't whitelisted. Make sure your current IP address is on your Atlas cluster's IP whitelist: https://www.mongodb.com/docs/atlas/security-whitelist/

The thing is that it worked yesterday, and I haven’t changed anything. I have Allow access from anywhere enabled, and my password + user both works. Is the problem due to some rate limit or something?

I’m using a free shared cluster on mongoDB.

await mongoose.connect("mongodb+srv://<user>:<pw>@Bussar.s5cyugd.mongodb.net/bussdb?retryWrites=true&w=majority"

I am currently trying to create a chart which always has a centered y-axis also when the user zooms into it. I would like the user to be able to focus around the values around the y-axis as this is what is most relevant to him.

I wasn’t able to find an option in the ECharts API to achieve what I want to. I have created an example here.

I am trying to find the total number of views of all videos in a playlist I own in YouTube. I can see that a “total views” number is posted under the playlist name. However this appears to be the number of views generated by entering the playlist first. When I add up the number of views of individual videos I get a substantially larger number because, I assume, most of videos are watched by following a link other than the playlist.

In searching for an answer I see two suggestions

1. using the following JS in the YT console

ytInitialData.header.playlistHeaderRenderer.viewCountText.simpleText

But this just gives the same number that is available under the playlist name.

2. using the following

var totalViews = 0;
var videos = document.querySelectorAll('ytd-playlist-video-renderer');
for (var i= 0; i < videos.length; i++)  {
    var viewsElement = videos[i].querySelector('#metadata > span:nth- child(1)');
    if (viewsElement !== null) {
        var views = viewsElement.textContent.trim().replace(/D/g,'');
        totalViews += parseInt(views);
    }
}
console.log('Total views of all videos in the playlist: ' + totalViews);

But this gives a total count of 0.

I would like to draw two oblique lines that would join two corners of two different divs. I need these lines to be responsive. My project currently uses angular but my problem, I think, can be solved with css. I also can’t use external libraries. enter image description here

I tried svg and I don’t know if I used it wrong but it was not responsive.

 <svg width="220" height="240" class="roadLink"><line x1="50" y1="60" x2="530" y2="220" stroke="black"/></svg>
        <div class="mb-2 d-flex">
            <div class=" d-flex justify-content-between roadSize topAnrpBlock">
            </div>
        </div>
        <svg width="140" height="100" class="roadLink"><line x1="50" y1="50" x2="500" y2="200" stroke="black"/></svg>

I want to have checkboxes to select the column I want to show and I can drag and drop the table columns.

For example if I want to iterate on a large array of data, can I do it outside? with some of web api features

I am trying to make a regex for JS. following are inputs

PREFIX hello SUFFIX
PREFIX PREFIX SUFFIX
PREFIX SUFFIX SUFFIX
PREFIX var+2 SUFFIX

Note: PREFIX and SUFFIX are kind of fixed. in between these words, we can have any number. of words.

I came up with this regex

(PREFIX(?=(?<spaces>[sS]+SUFFIX))k<spaces>)

but this one was reported as polynomial

I am converting binary file’s buffer to base64 text before storing to mongodb. I am using multer to get image alongside with with other field. I am sending those data in FormData and the back end is

app.post('/image', multer().single('image'), (req, res) => {
    const image = Buffer.from(req.file.buffer).toString('base64')
    database.collection('images').insertOne({image})
}

Now, how do I decode this base64 text to binary image?

I tried this in the front end after getting the json from the back end

URL.createObjectURL(new Blob([window.atob(data.image)]))

But I think the binary file is corrupted.
