When I use router.go in Ojet like below

self.args.router.go({ path: serverData.nextViewUrl, params: { c: serverData.sessionId } });

I get the following URL

?ojr=start_form%3Bc%3D63A4CC7E647582AF7E6C634B7FBF82F2

Above is the encoded URL. How do I get the correct decoded url by default in Ojet like below:

?ojr=start_form&c=D63A4CC7E647582AF7E6C634B7FBF82F2

Additional info:
Following is my router setup:

// Router setup
      let router = new CoreRouter(navData, {
        urlAdapter: new UrlParamAdapter()
      });
      router.sync();

      this.moduleAdapter = new ModuleRouterAdapter(router);

      this.selection = new KnockoutRouterAdapter(router);

      // Setup the navDataProvider with the routes, excluding the first redirected
      // route.
      this.navDataProvider = new ArrayDataProvider(navData.slice(1), { keyAttributes: "path" });

I am using the latest OJet v11

I’m trying to make a conditional checker check whether the element has any attributes or not.

var result = parentElm.hasAttribute(); i tried using this but I’m not sure I want a specific attribute by name, I just want to check whether the element has any attributes or attribute like length, size, or idk.

copyFormatCommand.js

    const model = this.editor.model;
    const selection = model.document.selection;
    const parentElm = selection.focus.parent;
    this.isEnabled = !!parentElm;
  

Here is the HTML I’m using to test if there are multiple nested elements and want to check whether the textNode‘s parent element has any attributes
HTML

<p style="font: 11pt Times New Roman, Times, Serif; margin: 0;" xvid="c0fc3b7176d15af5d8c5c488a7fa675e"><span xvid="6f8db94eb5824fc90d39a2d9a127a98d">Annual Fund Operating Expenses</span></p>
<p style="font: 11pt Times New Roman, Times, Serif; margin: 0;" xvid="c0fc3b7176d15af5d8c5c488a7fa675e">
    <span xvid="6f8db94eb5824fc90d39a2d9a127a98d"><span xvid="1">hello</span></span>
</p>
<p>hello</p>

I have a div with id map for leatleft and its only show one tile of map
i really have problem to show full map
please help me

my css style is

#map {
        height: 350px;
        width: 100%;
    }

and my code is

var mymap = L.map('map').setView([35.7336466, 51.3458287], 12);

    L.tileLayer('https://b.tile.openstreetmap.fr/hot/{z}/{x}/{y}.png', {
        attribution: 'hello world',
        maxZoom: 18,
    }).addTo(mymap);

mymap.locate({
        setView: true,
        maxZoom: 12
    });

I’ve been trying to figure this one out – if someone has some pointers I would appriciate it. Basically I got an object which has 3 properties, I need to check if one of those properties is true or false, and return based true/false.
So far, made this code but as I understand it doesn’t recognize object.properties..

const library = [
  {
    title: "Bill Gates",
    author: "The Road Ahead",
    isRead: true
  },
  {
    title: "Steve Jobs",
    author: "Walter Isaacson",
    isRead: true
  },
  {
    title: "Mockingjay: The Final Book of The Hunger Games",
    author: "Suzanne Collins",
    isRead: false
  }
];

const showStatus = (arg) => {
  let book = arg;
  for(let i = 0;i < book.length; i++){
    if(book.isRead === true){
       console.log(`Already read ${book.title} by ${book.author}.`)
    } else {
      console.log(`You still need to read ${book.title} by ${book.author}`)
    }

  }

};

showStatus(library);

I want to get all my object models from the database and store them in someway, the model I have is:

class Device (models.Model):
    patientId = models.IntegerField(unique=True)
    deviceId = models.CharField(unique=True,max_length=100)
    hour = models.DateTimeField()
    type = models.IntegerField()
    glucoseValue = models.IntegerField()

I’m sending them in views.py:

device_list = list(Device.objects.all())
context = {"filename": filename,
           "deviceList": device_list,
               }

In JS I managed to get each object like that:

{% for item in deviceList%}
console.log( "{{item}}" );
{% endfor %}

What I want is to store those objects in some way, but I don’t really know how, because they are coming like that Model object (1).

this is my code and i am unable console log.

Trying to make a website with multiple different dimension conversions. have successfully completed length however with almost the exact same code weight is not working. Here is my code:

    <section class="inputsW">
                <input type="number"  name="tonne" id="tonne" class="inputW" placeholder="Tonnes">
                
                <input type="number" name="kilo" id="kilo" class="inputW" placeholder="Kilograms">
                
                <input type="number" name="gram" id="gram" class="inputW" placeholder="Grams">
                
                <input type="number" name="milligram" id="milligram" class="inputW" placeholder="Milligrams">
                
                <input type="number" name="ton" id="ton" class="inputW" placeholder="US Tons">
                
                <input type="number" name="stone" id="stone" class="inputW" placeholder="Stone">
                
                <input type="number" name="pound" id="pound" class="inputW" placeholder="Pounds">
                
                <input type="number" name="ounce" id="ounce" class="inputW" placeholder="Ounces">

I am pretty happy with my html, I believe the problem lies within the (e.target.name) for the switch statement as this code works perfectly well for the first converter.

const tonneInput = document.getElementById("tonne");
const kiloInput = document.getElementById("kilo");
const gramInput = document.getElementById("gram");
const milligramInput = document.getElementById("milligram");
const tonInput = document.getElementById("ton");
const stoneInput = document.getElementById("stone");
const poundInput = document.getElementById("pound");
const ounceInput = document.getElementById("ounce");
const inputs = document.getElementsByClassName("input");


for (let i = 0; i < inputsL.length; i++) {
  let input = inputsL[i];

    input.addEventListener("input", function (e) {
        let value = parseFloat(e.target.value);
    
    
        switch (e.target.name) {

I have two onclick functions that performing start and stop functions using socket when i click start it start requesting images from server(i am using intervals) when i click stop the server is stopped but the request keep coming to the server. the intervals seems not stopped after clicking kindly review my code

Code:

  var interval;
  
  function onclick() {
    interval = setInterval(() => {
      socket.emit("get_image", "Click");
      socket.on('send_image', (message) => {
        setImage(message.image); 
      });
    }, 350)
  }

  function onclicks() {
    clearInterval(interval);
    setImage(blanked);

  }

I have tried to add clearInterval function but it seems not working

I have a bunch array of objects with participants and messages, I want to filter the object with the below array of two participants, can anyone help with this

this is the example participnats of array :

["61badffe4ccf060b329441e0","61bc33a84ccf060b32944354"]

bunch of sample messages and participants :

  {
    "messages": [],

  },
  {
    "messages": [],
    "participants": [
      "61bae1014ccf060b3294420e",

**expected below object after filter participants:** 

```{
    "messages": [],
    "participants": [
      "61badffe4ccf060b329441e0",
      "61bc33a84ccf060b32944354"
    ],
    "_id": "61d476dff651471663a72971",
  },

my collection has phonenumber field. i want to add 91 infront of phonenumber.

{
"_id": "6137392141bbb7723",
"email": "[email protected]",
"lastname": "Cagle",
"firstname": "Brooke",
"phonenumber":9000000001

"email": "[email protected]",
"lastname": "Cagle",
"firstname": "Brooke",
"phonenumber":9000000002
}

i want to update my collection like this.

{
"_id": "6137392141bbb7723",
"email": "[email protected]",
"lastname": "Cagle",
"firstname": "Brooke",
"phonenumber":919000000001

"email": "[email protected]",
"lastname": "Cagle",
"firstname": "Brooke",
"phonenumber":919000000002
}

im trying with this code but its not updating the field.

var x = await User.find({});
        x.forEach(async function(d)
            { 
                var phone = d.phonenumber;  
                var newPhoneNumber = 910000000000+phone;
                console.log(newPhoneNumber);

                //update 
            await User.updateMany({},{$set:{phonenumber:newPhoneNumber}},
                {
                    new: true, 
                    runValidators : true
                });
            })

im getting only one value for all documents like this:

{
"_id": "6137392141bbb7723",
"email": "[email protected]",
"lastname": "Cagle",
"firstname": "Brooke",
"phonenumber":919000000001
},
{
"_id": "6137392141bbe30723",
"email": "[email protected]",

"email": "[email protected]",
"lastname": "Cagle",
"firstname": "Brooke",
"phonenumber":919000000001
}

i don’t know whether this approach is correct or not.Thank you

I have an argument that passes me a 2D array and I want to get the numbers from that array and put them on a normal array.

The argument passed to me = ([1, 3, 2], [5, 2, 1, 4], [2, 1])
What I want to do = [1, 3, 2, 5, 2, 1, 4, 2, 1]

Thanks in advance, I think I’m having a brain fart over here!

I’m trying to make a simple Chrome extension that replaces all images with another one (img.jpg).

Main folder

• clrimgs.js
• img.jpg
• manifest.json
• window.html

window.html:

<!DOCTYPE html>

    <script type="text/javascript" src="clrimgs.js"></script>
</head>
<body>
    <button onclick="clrimgs()"></button>
</body>
</html>

clrimgs.js:

function clrimgs(){
    images = document.getElementsByTagName("img")
    for(image in images){
        image.src = "img.jpg";
    }
}

manifest.json:

{
    "manifest_version": 3,
    "name": "ClrImgs",
    "description": "Description",
    "version": "1.0",
    "minimum_chrome_version": "46",

       },
    "action": {
    "default_icon": "img.jpg",
    "default_popup": "window.html"
    }
    }

When I try to reload the extension, I get this error:

Is there any way to use MV3 and still use such code? If yes, what am I doing wrong? I have tried doing numerous things, but I keep getting an error or the other.

I have a requirement where in a user input the regular expression should match only numbers either digits or numbers with decimal points, however if there is a number followed with a percentage symbol then that should be excluded, but numbers followed with alphabets like 100g or 500 grams should be matched without picking up the alphabet part

I have come up with the following:

let numberPart = importValue.match(/d+(?:[.,]d+)?b(?!(?:[.,]d+)|(?:s?%|spercent))/g);

11 grams nutella 1,5% is matched and we get 11 as output

however 11grams nutella 1,5% isn’t matched

how can I change it so it matches numbers followed immediately by an alphabet or alphabets.

How v8 engine runs and where does it run?
I found some resources where I got that it runs in the browser but what about in node js? please try to understand me. where does it run?
