I’m trying to send the id of the object to the controller with the button. But it only does this for an item in the first row of the list. The button does not work for other items in the list. How can I solve the problem?

$(document).ready(function(){       
            $("#showTweet").click(function(){
         var tweetId = $(this).parent().attr('id');
        $.ajax({
        
        type: "GET",
        dataType: "json",
        url: "http://localhost:8020/showTweet?tweetId="+tweetId,
        success: function(result){
            var description = result.description;
            $('#tweetText').text(description);
            
             }
        });
    });

I am wondering why the statement “let im = _imgs[i];” is indispensable in this situation.
Essentially, the _imgs are an array of image elements. But if I add the eventhandlers by _imgs[i].addEventListener("click", function(){clickImage(_imgs[i]);}, false);, it won’t work.

Can anyone explain why? Thanks a lot!

function init()
{
    _imgs = document.querySelectorAll("#block2 img");
    console.log(_imgs.length);
    _clicked = new Object();
    for(var i = 0; i < _imgs.length; i++)    
    {      
        let im = _imgs[i];
        _imgs[i].addEventListener("click", function(){clickImage(im);}, false);
        _clicked[_imgs[i].id] = 0;
    }
    console.log("hi");
}

I’m creating a website which has daily news updates with URL links. I need to add a NEW! text on top of the link and once the user has visited it, need to remove the text. I searched for it everywhere what this feature is called and also went through anchor tag attribute in CSS i.e. a:visited {}, but it’s only CSS, how can I use for the above scenario?

Also if there’s any other way to deal with newly added links and after certain time, the NEW! text is gone, please let me know, I’m unable to find any resources online. Thanks.

If we run the following code in safari it fails saying “failed to load resource: cannot parse response”

fetch('https://mycompanyname/service/contracts-api/operatingMode', {
  method: "GET",
  headers: new Headers({
    'Authorization': 'Basic VGVzdFVzZXIxOlRFU1QhdXNlcjE=',
    'X-mycompanyname-ContractsServer': 'someurl'
  })
}

But if we run the same code in Chrome or Firefox, it succeeds (in the same mac computer).

Is there any quirk in Safari fetch request that I am not considering?

How come a gets logged and b doesn’t? Is a somehow appended to the global scope, while b remains within hoist() scope?

function hoist() {
  a = 20;
  var b = 100;
}

hoist();

console.log(a);
// Output: 20

console.log(b);
// Output: ReferenceError: b is not defined

I am building a survey form that gathers information from students, using HTML (open to using javascript too) and have found several examples online but none seem to be working. The survey form is currently just selecting these:

The survey should be selecting all options (first name, last name, living place, college choices, major, campus visit), and I don’t know how to fix this.

This is the survey and the code:

Trying to write this in a way that it will wait for the db operations to complete. Possible?

function addFriendsToSession(session, sessionId) {
    const friends = [];

    const incoming = session.users.forEach(async user => {
        console.log('user', user);
        await db
            .collection('users/' + user + '/settings')
            .doc(user)
            .get()
            .then(doc => {
                if (doc.exists) {
                    const returnObj = doc.data();
                    return returnObj.friends ? returnObj.friends : [];
                } else {
                    return [];
                }
            });
    });
    friends.push(incoming);
    return friends;
}

I wrote a function where I am looping through an array(which contains a number of array elements itself).
e.g. theMainAr:[ [ 5 ],[ 5, 3 ],[ 5, 3, 9 ],[ 5, 3, 9, 4 ],[ 3 ],[ 3, 9 ],[ 3, 9, 4 ],[ 9 ],[ 9, 4 ],[ 4 ] ]
The main array I got the above array from is : weights: [5,3,9,4]
I want to get a combination from these above arrays like this:sameLenAr:[[5,9],[5,4],[5,3,4],[3,4]]
My code is:

let sameLenAr = []
    let inc = 0
    for(let i=1;i<theMainAr.length-3;i++){  
        let curLen = theMainAr[i].length
        if(curLen>1){
            let curAr = theMainAr[i]
            let curArLen = curAr.length
            let indexOfEle = weights.indexOf(curAr[curLen-1])
              for(let m=indexOfEle+1; m<lenOfWets;m++){
                //   console.log(a)
                 curAr[curArLen -1] = weights[m]
                 console.log(curAr)
                 sameLenAr[inc] = curAr
                 inc++
                }
        }
    }

But Everytime I get an output like this: [[5,4],[5,4],[5,3,4],[3,4]]
The first element is not [5,9]
Why?

I am using JavaScript to submit the popup dialog, but it’s not submitting.

here is my view, I have checked the javascript, it is firing up but the $(“form”).submit() statement is not doing anything and the next statement is executed.

@{ 
    ViewBag.Title = "Add Comment";
    Layout = "~/Views/Shared/Popup.cshtml"; 
}

<script type="text/javascript">
    $(document).ready(function () {
        $("#SaveComment").click(function (e) {
            e.preventDefault();
            $("#form").submit();
            parent.HidePopup(true);
        });
    });
    </script>

@using (Html.BeginForm("CreateComment", "OnlineInventory", FormMethod.Post, new { id = "form"}))
{
    @Html.Hidden("OccupantInventoryRoomId", Model.OccupantInventoryRoomId)
    @Html.Hidden("OccupantInventoryItemId", Model.OccupantInventoryItemId)
    @Html.HiddenFor(m => m.AllocationId)
    @Html.HiddenFor(m => m.Status)

    @Html.TextAreaFor(m => m.Comment, new { Class="CommentTextBox" })
    <div class="Navigation">
        <input type="button" value="Cancel" onclick="parent.HidePopup(false)" />
        <input id="SaveComment" type="button" value="Save" class="InputButton"/>
    </div>
}

this is my controller

  public class OnlineInventoryController : Controller
    {
        [HttpPost]
        public ActionResult CreateComment(AddNewCommentModel model, int? allocationId)
        {
            User user = this.userProvider.GetByUserName(System.Web.HttpContext.Current.User.Identity.Name);

            if (!this.userProvider.IsAllowed(9, user.KxId))
            {
                return this.RedirectToAction("Index", "Inspections");
            }

            try
            {
                OccupantInventoryComment commentToSave = new OccupantInventoryComment
                {
                    Comment = model.Comment,
                    CommentDateTime = DateTime.Now,
                    CreatedByUserId = user.KxId,
                    OccupantInventoryRoomId = model.OccupantInventoryRoomId,
                    OccupantInventoryItemId = model.OccupantInventoryItemId,
                };
                ViewBag.OccupantInventoryRoomId = model.OccupantInventoryRoomId;
                ViewBag.OccupantInventoryItemId = model.OccupantInventoryItemId;
                this.occupantInventoryCommentProvider.Save(commentToSave);
            }
            catch (Exception ex)
            {
                this._audit.Add(Product.KxRoomCheckerBackOffice, Severity.Error, ActivityType.Create, new StackTrace().GetFrame(0).GetMethod().Name, string.Empty, string.Empty, ex);
            }

            return this.RedirectToAction(model.Status.ToString(), new InventoryModel { AllocationId = model.AllocationId, Updated = true });
        }
}

In the preview screen the camera will be on based on image captured by the camera it should detect whether the person is sitting on low light condition or not and the client needs to receive a notification regarding it.

Im getting this error which I’m not completely sure how to solve.

    CommentModel.getCommentsForPost = (postId) => {
    let baseSQL = `SELECT u.username, c.comment, c.created, c.id
    FROM comments c
    JOIN users u
    on u.id=fk_authorid
    WHERE c.fk_postid=?
    ORDER BY c.created DESC`;
    return db.query(baseSQL, [postId])
        .then(([results, fields]) => {
            return Promise.resolve(results);
        }).catch(err => Promise.reject(err));
};

Error:

      code: 'ER_BAD_FIELD_ERROR',
  errno: 1054,
  sql: 'SELECT u.username, c.comment, c.created, c.idn' +

Any help would be appreciated!

I’m making a free custom website creator tool with drag and drop.
One can make the desired page by dragging elements to a div section which is then reviewed.
I want the user to copy the code inside that div section so he may be able to use it.
I’m totally new to java so I don’t know how to do so.
Please help me that how can I copy The code inside a div. So, I may be able to help people to generate their own custom templates without paying a single dollar.

note: this is a static website so nothing is being done on the server.

The way my slash command handler works is I iterate through all the current client guilds, add an object to an array with the keys ‘id’ and ‘commands’, id being an integer of the guild id and commands being an array.

Then, iterate through the commands directory, require the file, check if the slash command builder has a ‘guilds’ element, in which the code will iterate through the guilds element and add the command builder to every guild commands array in the beforementioned guild array.

Then, once all is complete, iterate through the guilds array, find the guild by id, commands.set. All is working, except it only adds the commands to one of the guilds. In the iteration forEach of the guild array, I’ve made it console.log the id of the guild, and console.log after the setting of the commands. Both log properly, no errors thrown, but only my original testing server has the commands registered, and not a new server that a friend owns.

Ensured all intents are valid, administrator issued and role is high as it needs to be. Super confused!

    let guilds = []

    client.guilds.cache.forEach(guild => {
        guilds.push({
            id: guild.id,
            commands: []
        })
    })

    function addToGuild(id, obj) {
        guilds.forEach(guild => {
            if (guild.id == id) {
                guild.commands.push(obj)
                return true
            }
        })
    }

    fs.readdirSync(`${process.cwd()}/commands`).forEach(file => {
        if (file.endsWith('.js')) {
            let requiry = require(`${process.cwd()}/commands/${file}`)
            if (requiry.command.guilds) {
                requiry.command.guilds.forEach(guild => {
                    addToGuild(guild, requiry.command)
                })
            } else {
                guilds.forEach(guild => {
                    guild.commands.push(requiry.command)
                })
            }
        }
    })

    guilds.forEach((guild) => {
        console.log(guild.id)
        client.guilds.cache.find(guild => guild.id == guild.id).commands.set(guild.commands)
    })

I’ve got a problema running now that is: I need a function that find the highest number made by consecutive digits within that number that I received by the parameter.
For example: If my input is 1235789 my output should be 789. If my input is 123689, my output should be 123.

function getbiggestNumber(numberInput) {
    const numberString = numberInput.toString(); // turned into string

    const temporaryResult = []; // create the array of possible solutions which i'd go through to find the highest value inside of it

    for (let i = 0; i < numberString.length; i += 1) {
        const temporary = [numberString[i]]; // create a temporary answer that would serve as a base

        for (let x = i + 1; x < numberString.length; x += 1) {
            const subResult = Number(numberString[i]) - Number(numberString[x]); // the result of the current number minus the following number

            if (subResult === -1) { // if they are in a sequence this should be -1
                temporary.push(numberString[x]); // pushing this number to that temporary answer
            } // here should be some condition for it to keep running, instead getting into another number of for loop
        }
        temporaryResult.push(temporary); //  pushing that temporary answer to the result, so I could keep track of it
    }
    console.log(temporaryResult); //  checking the output
}

The problem is that this code is only providing double digits inside a array, and that was the only way I found to do this.
I’d be really thankful if someone could give me a light on this.
Thanks!
