I have a video on my page. How can I add a zoom-out and zoom-in button to the video I’ve published on the page in Vue.js? I made the time-slider.

I have an Material UI text field which is populated by a nested JSON object pulled from an API.

Text is displaying in the textField just fine, but it cannot be changed. It is not accepting any new text.

{questions['Days']?.map((row) => (
  <TextField
    fullWidth
    multiline
    className="text-field"
    value={row?.Response || ''}
    onChange={(e) => {
        setQuestions((prev) => { return { ...prev, Response: e.target.value };
        });
    }}
    variant="outlined"
    margin="normal"
    label={row['Question']}
  />
))}

An Example of my JSON:

{
  "Days": [
    {
      "Question": "What day is it today?",
      "Response": "Wednesday"
    }
  ],
  "Time": [
    {
      "Question": "What time was it when you answered this question?",
      "Response": "11:45 am"
    }
  ]
}

Is it possible to use one method to create textFields for multiple nested JSON objects rather than hard coding them?

Is there any library in JavaScript to show differences between two trees of files?

I want to show one tree with my actual version of a project and another tree with the remote version. I want to highlight the changes between both trees: the files that are modified, deleted or added in my local version vs. my remote version.

// in v2 mode we can use this

"background": {
  "scripts": [
     "background.js", "url.js", "bg.js", "setcookie.js",  "jquery.js"
  ] },

//but in v3 mode we have only one script

 "background": {
  "service_worker": "service-worker.js",  "type": "module" },

i have 4-5 backgroud file for different events how i can add these file in V3 menifest

How can i deconstruct an array, and put it into the array which is getting mapped on, then continue sorting on that?

Basicly the array looks the following after filtering it:

[

[‘traitName’, ‘value’],

[‘traitName’, [‘value01’, ‘value02’, ‘value03’ …]
],

…

]

What i want to do is check every trait, and check if the first index is an array, then deconstruct that, and put it into this array like this:

[

[‘traitName’, ‘value’],

[‘traitName’, value01],

[‘traitName’, value02],

[‘traitName’, value03],

..
],

…

]

Then i can continue sorting on this array.

 Object.entries(nft)
                .filter((val: any) => val[0] !== 'Attributes' && data.attributes[val[0]] !== undefined)
                .sort((a: any, b: any) => {
                  if (typeof a[1] === 'number') return Infinity;
                  return (
                    data.attributes[a[0]]?.values[a[1]]?.distribution - data.attributes[b[0]]?.values[b[1]]?.distribution
                  );
                })

I need to this between the filter and sorting i think.

My code’s output is like this:

let myArray = [{"num": "2", "name": "Jhon"}, {"num": "1", "name": "Sara"}, {"num": "2", "name": "Domnic"}, {"num": "3", "name": "Bravo"}]

How can I access value of num in each field of the list and if num: 2, change its value to 5?

i am working on reactjs ag-grid and react video player. first of all i create json file with following data and video path links

db.json :

{
  "users": [
    {
      "id": 1,
      "name": "Manoj",
      "email": "[email protected]",
      "phone": "9876543210",
      "videolink": "/home/fraction/Downloads/agGrid-crudOperation/server/Fraction.mp4"
    },
    {
      "name": "Vikas Kumar",
      "email": "[email protected]",
      "phone": "+9876543210",
      "videolink": "/home/fraction/Downloads/agGrid-crudOperation/server/Fraction.mp4",
      "id": 5
    }
  ]
}

After that i create ag-grid table with action button method after creating grid table

And pass video link to Play button and print it in console as well.

function App() {
const actionButton=(params)=>{
  console.log(params)
}

  const [gridApi, setGridApi] = useState(null)
  const [tableData, setTableData] = useState(null)
  const [open, setOpen] = React.useState(false);
  const [formData, setFormData] = useState(initialValue)
  

  const handleClose = () => {
    setOpen(false);
    setFormData(initialValue)
  };
  const url = `http://localhost:3000/users`
  const columnDefs = [
    { headerName: "ID", field: "id" },
    { headerName: "Name", field: "name", },
    { headerName: "Email", field: "email", },
    { headerName: "Phone", field: "phone" },
    { headerName: "VideoLink", field: "videolink" },
    {
      headerName: "Actions", field: "videolink", cellRendererFramework: (params) => <div>
        <Button variant="contained" size="medium" color="primary" onClick={()=> actionButton(params)} >Play</Button>
        {/* <Button variant="outlined" color="secondary" onClick={() => handleDelete(params.value)}>Delete</Button> */}
        
      </div>
   
    }
    
  ]

i tried to pass video link to react video player and i am used to create react video player with this link

now to how to play videos in react popup video player whenever i click play or update button

Thank in advance

I get data from a csv file but it got error: “Uncaught (in promise) TypeError: data.map is not a function”

d3.csv("http://127.0.0.1:8887/data.csv", function(data) {
      xScale.domain(data.map(function(d) {
        return d.year;
      }));
      yScale.domain([0, d3.max(data, function(d) {
        return d.value;
      })]);

      g.append("g")
        .attr("transform", "translate(0," + height + ")")
        .call(d3.axisBottom(xScale));

      g.append("g")
        .call(d3.axisLeft(yScale).tickFormat(function(d) {
          return "$" + d;
        }).ticks(10));

Can someone help to solve this issue?

i have this code and i dont know what does =+ means it does not work like += hence

x+=y adds y value to x but x=+ it looks like its replace x value with y value

var counters= document.querySelectorAll('.counter'); 
counters.forEach(counter => {

    counter.innerText= '0' ; 
    const updateCounter = ()=> {
        const target =+ counter.getAttribute('data-target')
        const c = +counter.innerText
        const increasment = target/200;
        if(c<target) {
            counter.innerText = c+increasment ; 
            setTimeout(updateCounter,5)
        }
        else {
            counter.innerText=target 
        }
     
     
        
    }

    updateCounter(); 
})

So I’ve been trying to make a program that shows you near tourist attractions. The problem I am encountering is that the program is showing me seemingly random attractions, in complete disregard for my current location and the entered radius. I think that the problem should lie in the following code:

function getNearbyPlaces(position) {
console.log(position + "##############################");
request = {
   location: position,
   radius: '300',
   query: ['tourist_attraction']
};
service = new google.maps.places.PlacesService(map);
service.textSearch(request, callback);

I’d love some ideas on how to solve this issue and how to get this code working. Be aware I am pretty new to JavaScript!

I am making a flutter app and i am using an express.js Backend. I set it up and it works fine when using it on localhost but not when deploying it to an ubuntu server. Postman then just instantly says “Socket hang up”. When using curl or putting it into the browser everything just works fine. Any ideas what could be wrong?

I have created my mongoose user_schema like below

const mongoose = require('mongoose')
const interactions = require('./interaction').schema
const Schema = mongoose.Schema;

const UserSchema = new Schema({
    name: String,
    email: { type: String, unique: true, required: true },
    password: { type: String, required: true, },
    dob: Date,
    address: { type: Schema.Types.ObjectId, ref: 'Address' },
    profile_pic: String,
    resume: { type: Schema.Types.ObjectId, ref: 'Resume' },
    interactions: [interactions]
        
    
})

module.exports = mongoose.model("User", UserSchema)

and this is the interaction_schema

const mongoose = require('mongoose')
const helpers = require('../utils/helpers.js')
const Schema = mongoose.Schema;

const InteractionSchema = new Schema({
    interaction_type: {
        type: String,
        enum: helpers.interaction_choices,
        default: helpers.interaction_choices.liked
    },
    interacted_with: { type: String, required: true },
    }, {
    timestamps: true
})    

module.exports = mongoose.model("Interaction", InteractionSchema)

For the interaction_choice, I have used a const variable like this

const interaction_choices = {
    sent: 'sent',
    liked: 'liked',
    rejected: 'rejected',
    incoming: 'incoming',
    connected: 'connected',
}    

module.exports = { interaction_choices }

Now, to add a new interaction I am doing this

async function sendRequest(senderId, recieverId) {
  const senderUpdates = {
    interaction_type: helpers.interaction_choices.sent,
    interacted_with: senderId,
  };
  const recieverUpdates = {
    interaction_type: helpers.interaction_choices.incoming,
    interacted_with: recieverId,
  };
  try {
    await User.findByIdAndUpdate(senderId, {
      $push: {
        interactions: senderUpdates,
      },
    });
  } catch (error) {
    console.log("Sender Error : " + error);
    return false;
  }
  try {
    await User.findByIdAndUpdate(recieverId, {
      $push: {
        interactions: recieverUpdates,
      },
    });
  } catch (error) {
    console.log("Reciever Error : " + error);
    return false;
  }
  return true;
}

Till now, everything is working as per my expectations. But now I am stuck on removing one specific interaction for a user, based on the interacted_with field of interaction_schema. Please guide me what should I do to do so. Thank you so much.

When a browser navigates to an URL like http://example.com/#foo, it scrolls to the element identified by #foo; this element of the URI is called a fragment identifier. Suppose I have a fragment identifier for an element on the current page, which I have not yet navigated to. How can I find out which DOM node would have been targeted by it?

• It’s not enough to use document.getElementById, because a fragment identifier #foo can also target an old-style anchor, <a name="foo">, which this method misses.
• It’s not correct to use document.getElementsByName either, because that would find non-anchors like <input> or <textarea> nodes, and miss elements identified by the id= attribute.
• Since I have not navigated at the fragment, I cannot use document.querySelector(':target') either.

Is there a reliable way to find which DOM node would have been targeted by fragment identifier that catches all cases? If the solution uses querySelector, I would of course like it to be robust against unusual characters found within identifiers, however deprecated they may be.

I have a hard time finding the right answer to this question.

I have an array with 10 objects. I created each object as its own div.

I want to show each div for 1 sec the hide it for 1 sec then show the next one and so on until all 10 objects been showed once, then I want to show a next button.

I understand I need set interval and set timeout, but I dont know how?

In JavaScript have code like:

const text = 'starttext <- code1 -> middletext <- code2 -> endtext';

And I want to get:

starttext  middletext  endtext

First I tried:

text.replace(/<- .+ ->/, '');

But it returns:

starttext  endtext

… because it matches:

< ""anything"" >

But I need to match:

< ""anything but >"" >

So I tried negative overhead:

text.replace(/<- (?!->).+ ->/, '');

… but it works only with alphanumeric characters for me.
How can I make it work with ->?
