          $("[formcontrolname='"+Data[key].formname+"']").val(Data[key].value);
                        
                        await wait (1000)                        
                    }

I am trying to develop an extension for chrome. I did the necessary operations in the Process.js file. The codes worked but I got an undefined query error. This error did not prevent the code. There was a problem only in the share part in Google Slides. what do you think is the reason?
The system is working, but how can i prevent that warning ?
Please help me ?

Share google slides button not working. It works when I remove the plugin.

process.js

chrome.tabs.query({active: true, lastFocusedWindow: true}, tabs => {
    let url = tabs[0].url;
    url = url.replace('//', ';;').replace(/[/]/g, ';');
    let pageTitle = tabs[0].title;
    pageTitle = pageTitle.replaceAll("'", '*');
    pageTitle = pageTitle.replaceAll('"', '**');
    pageTitle = pageTitle.replace('//', '__').replace(/[/_]/g, '_');

});

I am making an axios.post() request in my Vue component to send some formData holding a media File to upload through a PHP script. I know the file object is being appended correctly as I log the data before the request here:

// this.postMedia is a Vue array holding any post media objects to be uploaded
this.postMedia.forEach((mediaObj, index) => {
    formData.append('media[' + index + ']', mediaObj.media);
    formData.append('mediaType[' + index + ']', mediaObj.mediaType);
});

// Logging formData
for (let p of formData.entries()) {
    console.log(p);
}

This logs the information of the file object and the corresponding media type as expected.

// This is the media data
File {
    lastModified: 1627299857401
    lastModifiedDate: Mon Jul 26 2021 07:44:17 GMT-0400 (Eastern Daylight Time) {}
    name: "test-image.jpg"
    size: 12295
    type: "image/jpeg"
    webkitRelativePath: ""
}

// This is the mediaType data
1

I am then passing this data through an axios request and logging the response data as follows:

// Vue.js file
axios.post('/api/createPostV2', formData, config)
.then(success => {
    console.log(success.data);
})
.catch(function(err) {
    console.log(err.response);
});


// PHP file being requested (/api/createPostV2)
public static function createPostV2(Request $request)
{
    // Just return request to check data
    return $request->all();
}

Here is what gets logged:

media: Array(1)
    0: {}
    length: 1
    [[Prototype]]: Array(0)
mediaType: ['1']

So it is passing the media array, but the actual file is not being passed as you can see by the empty object at index 0. As you can see the mediaType is passed correctly, keep in mind both ‘media’ and ‘mediaType’ are arrays to support uploading multiple files. Am I missing something here? Why is the file data being lost when I am passing it through formData?

<script>
    const URL = "https://discord.com/api/guilds/899175503565553714";
    $.ajax({
        url: URL,
        type: "GET",
        headers: { Authorization: 'Bot ' + token } })
</script>

Here is my code

index.html:1 Access to XMLHttpRequest at 'https://discord.com/api/guilds/899175503565553714' from origin 'null' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

How can I send headers and receive values ​​successfully with jquery ?

I am trying to read from firestore and push that data into a global variable. I am able to push however the array acts differently outside the function (I’ve attached a screenshot from the console showing the dif). For example I can call data[0] or data[1] inside the function just fine but outside it returns “undefined“. Can anyone help with this?
This is for a react project, so if there is a way to do it using react hooks or something like that, I can implement no problem.

let fbData = [];

const GetData = async () => {
    const q = query(collection(db, "surveys"), where("surveyComplete", "==", true));
    const querySnapshot = await getDocs(q);
    querySnapshot.forEach((doc) => {
        fbData.push({
            [doc.data().surveyId]: {
                "name": doc.data().surveyName,
                "id": doc.data().surveyId
            }            
        });
    }, 
    function (error) {
        console.log("Error getting documents: ", error);
    });
}

And yes I know the way I structure my data is weird, I’m planning on fixing it once I figure this issue out.

thanks

I am creating a slot machine program using JavaScript, and want to decrement the value of coins at every function call. For example, coins = 20. It should decrement after every time the casino() function is called. Basically the function can be called as many times until coins = 0.
Is this a situation where the application of let vs var comes into play?
Here is a snippet of my code:

let reel1 = ["cherry", "lemon", "apple", "lemon", "banana", "banana", "lemon", "lemon"]
let reel2 = ["lemon", "apple", "lemon", "lemon", "cherry", "apple", "banana", "lemon"]
let reel3 = ["lemon", "apple", "lemon", "apple", "cherry", "lemon", "banana", "lemon"]
let slotReel = []
let coins = 20

function casino(r1, r2, r3) {
    coins = coins - 1
    let random1 = reel1[Math.floor(Math.random() * reel1.length)]
    let random2 = reel2[Math.floor(Math.random() * reel3.length)]
    let random3 = reel3[Math.floor(Math.random() * reel3.length)]
    slotReel.push(random1, random2, random3)
    //.....some logic
}

casino(reel1, reel2, reel3)

In styled-components we can have contextual styles using component selector patterns. But how do we parents variant to contextual the child component? For example, we have three components here, Child, NoteWrapper, and Note.

const Child = styled.div<{ editing?: boolean }>`
  ${props => props.editing && css`some styles`}
`

const NoteWrapper = styled.div<{ compact?: boolean }>`
  ${props => props.compact && css`some styles`}
`

const Note = styled.input`

/* How do I style this when Child is editing and NoteWrapper is compact */

`

const App = () => {
  return (
   <Child editing>
    <NoteWrapper compact>
     <Note/>
    </NoteWrapper>
   </Child>
  )
}

`

With plain CSS we could do something like this

.child.editing .note-wrapper.compact .note {
  /* Contextual styles here */
}

My question is how do I style Note when Child is editing and NoteWrapper is compact in styled components selector pattern ?

As my experience with react and angular, I don’t think I have done anything challenging where I had to scratch my head as most of my experience comes from business applications where there are fewer users. Only the complexities lie in business logic. Anyone can give some scenario like this can be very helpful.

I want to find a page url searching by an input. I have an object that contains keywords and urls. Then when press enter it will do a check, if the keywords are the same or exist, it will display the url, if not it will display not found.

So for example in the input I type “home”, when I enter it will display the url “/homepage” because the keywords are exist, if I type “contact” it will show not found because the keywords doesn’t exist.

I’ve made the code like below but why the map doesn’t work? can anyone help me?

$(document).ready(function(){
  $("#searchKeywords").on("keypress", function(e){
    if(e.which == 13){     
      const pageKeywords = {
        "home" : "/homepage",
        "about" : "/about-us"
      }

      pageKeywords.map((key,value) => {
        console.log(key)

        if($(this).val() == key){
          console.log(value)
        }else{
          console.log('not found')
        }
      })
    }
  });
})
