Building on a previous question

How do I wait until new content has been loaded before adding to results?

In the code i'm just writing in SUDO so to illustrate

var imgs = document.querySelectorAll('.photo-item img');
var results = [];
var seconds = 0;
for (var i = 0; i < imgs.length; i++) {
    imgs[i].click();
    do {
        console.log('In Do loop Seconds: ' + seconds);
        if (document.querySelector('.gallery-full-imag') != null) {
            var BigImgs = document.querySelectorAll('.gallery-full-imag img');
            results.push({
            src: BigImgs[0].src,
                data: BigImgs[0].dataset.img
            });
            seconds = 10;
        }
        else {
            setTimeout(function () { seconds++; }, 1000);
          
        }
} while (seconds<10);

     document.querySelector('.gallery-fullscreen-hide').click();
}
var json = JSON.stringify(results);

How can I make my text area editor disabled if the user typed in more than 4000 characters?

I have tried the disable syntax but it's not working

<link type="text/css" rel="stylesheet" href="~/Content/CWScss/jodit.min.css">
<script type="text/javascript" src="~/Scripts/jodit.min.js"></script>


 jQuery(function () {
            var maxLength4000 = 4000;
            $(document).on("keyup paste blur click touchend", function () {
                var textlen = maxLength4000 - $("#AttributesAndValue").val().length;

                 //Here I want to say if textlen more than 4000 char then disable my text editor 
                //my disable is not working 

                if ($("#AttributesAndValue").text().length == 4000 || textlen <= -1) {
                    $('#AttributesAndValue').prop("disabled", true);
                }


                $('#rchars').text(textlen);
            });
            $('#AttributesAndValue').each(function () {
                var AttributesAndValue = new Jodit(this);
                AttributesAndValue.setDisabled();
            });
        });


                  <div class="form-group purple-border">
                        Attribute(s) and Value(s)
                        @Html.TextArea("AttributesAndValue", new { @class = "form-control", @style = "width:77%" })
                          <div id="ValidateAttributesAndValue" style="color:#bc0606;font-weight:bold;">Required Field</div>

Given the snippet of html  how do I create a JSON string from each img with class = 'MyClass' to give both  src  and data-img

HTML

<h1>Hello world!</h1>


<div>
  <div class='MyClass'><img src='//image.tmdb.org/t/p/w185/fw02ONlDhrYjTSZV8XO6hhU3ds3.jpg' data-img=1234></div>

Here is a jsfiddle

I'm working with a fully functional Node.js code that interacts with the Fitbit API.

Being somewhat new to Node, however, has me in a spot where I need a little guidance.

The code looks like this:

// initialize the express application
const express = require("express");
const app = express();

// initialize the Fitbit API client
const FitbitApiClient = require("fitbit-node");
const client = new FitbitApiClient({
	clientId: "CLIENT_ID", //client_id
	clientSecret: "CLIENT_SECRET", //client secret
	apiVersion: '1.2' // 1.2 is the default
});

// redirect the user to the Fitbit authorization page
app.get("/authorize", (req, res) => {
	// request access to the user's activity, heartrate, location, nutrion, profile, settings, sleep, social, and weight scopes
	res.redirect(client.getAuthorizeUrl('activity heartrate location nutrition profile settings sleep social weight', 'http://localhost:3000/callback')); //callback url
});

// handle the callback from the Fitbit authorization flow
app.get("/callback", (req, res) => {
	// exchange the authorization code we just received for an access token
	client.getAccessToken(req.query.code, 'http://localhost:3000/callback').then(result => { //callback url
		// use the access token to fetch the user's profile information
		[b]client.get("/profile.json", result.access_token)[/b]
		[u]//client.get ("/1/user/[user-id]/[resource-path]/date/[date]/[period].json", result.access_token)[/u]
		.then(results => {
			res.send(results[0]);

Dear Experts,
I use PHP,
I need to get a result inside an object which is inside Json.
I get the parrent result like below.

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$server_output = curl_exec($ch);

var_dump ( $obj = json_decode($server_output));

echo $yeniobj= ($obj->result);

//Result is 
object(stdClass)#1 (10) { ["result"]=> string(90) "{"ReturnCode":0,"ReturnData":null,"Confirm":null,"TimeStamp":"04.11.2019 10:43:34"}" ["id"]=> int(135) ["exception"]=> NULL ["status"]=> int(5) ["isCanceled"]=> bool(false) ["isCompleted"]=> bool(true) ["isCompletedSuccessfully"]=> bool(true) ["creationOptions"]=> int(0) ["asyncState"]=> NULL ["isFaulted"]=> bool(false) }

echo $yeniobj= ($obj->result);

//Result is

{"ReturnCode":0,"ReturnData":null,"PaymentConfirm":null,"TimeStamp":"04.11.2019 10:43:34"}

But I need to result of the ReturnCode information.
How can I get that? thank you

Hi all, just trying to get the keys and values.

On line 8, Im using  Object.keys(item).forEach(function(key) {, but if I change it to  Object.entries(item).forEach(function(key) {

how do I get the keys and values?

Hi,

I am new to web development and c# and java script in particular.  I have a problem I have been stuck on for a few days.  I have a ASP Core project.  I have a button on a page that calls some javascript code to pass in a serial number and I want it to return some data from my controller.  There are several fields in my model data, but to keep it simple i will just try and show 2.  The problem is it is showing the serial number but any other field it shows the value as undefined when i load the page and press the button.

The java script I have is:
 

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
<script>

    $(document).ready(function () {
        $("#abc").click(function (e) {
            if ($("#SerialNumber").val() == "")
                alert("SerialNumber cannot be empty");
            else if ($("#Comments").val() == "")
                alert("Comments cannot be empty");
            else {
                $.ajax({
                    type: "POST",
                    url: "/Home/GetSecuredData",
                    data: {"serialNumber": + $("#SerialNumber").val() },
                    success: function (result, status, xhr)
                    {
                        var html1 = ""
                         $.each(result, function (items, OperationsData)
                        {
                
                                html1 += `

Hi,

I have lots of jsons which I d need to mass edit (add entries, remove, edit, based upon some logic).  F.e. if entry entry1.date.request is not existing add with value y etc
I d like to to this Powershell based. Also json validation needs to occur (syntax ok).

Maybe there is a tool also as backup/extra checks.

Hi All;

Im having the same error messages when sending data and receiving Json string using RS 232, before I start working on the gadget I want a second eye to  take a look on the code below, please  note the following :

9600 baud is converted to 64 bytes

All the  two codes for sending & receiving as well as for converting received data are called from the main code that has the data for sending since once the data is received by the gadget then the gadget is supposed to send a signature back instantly.

Receiving code

Private Sub CmdTaxReceive_Click()
Dim strData As String
Dim lngStatus As Long
Dim strError As String
Dim intPortID As Integer
' Read maximum of 64 bytes from serial port.
    lngStatus = CommRead(intPortID, strData, 64)

If lngStatus > 0 Then
        ' Process data.
 ElseIf lngStatus < 0 Then
      lngStatus = CommGetError(strError)
      MsgBox "COM Error: " & strError
      Stop
    End If
    
    lngStatus = CommFlush(intPortID)
    
    If lngStatus <> 0 Then
      lngStatus = CommGetError(strError)
      MsgBox "COM Error: " & strError
      Stop
    End If
' Reset modem control lines.
    lngStatus = CommSetLine(intPortID, LINE_RTS, False)
    lngStatus = CommSetLine(intPortID, LINE_DTR, False)
 ' Close communications.
    Call CommClose(intPortID)

End Sub

Sending code

Private Sub CmdSendTax_Click()
Dim intPortID As Integer ' Ex. 1, 2, 3, 4 for COM1 - COM4
    Dim lngStatus As Long
    Dim strError  As String
    Dim strData   As String
    Dim lngSize As Long

    ' Initialize Communications
    lngStatus = CommOpen(intPortID, "COM" & CStr(intPortID), _
        "baud=9600 parity=N data=8 stop=1")
    
    If lngStatus <> 0 Then
    ' Handle error.
        lngStatus = CommGetError(strError)
    MsgBox "COM Error: " & strError
    End If
 
    ' Set modem control lines.
    lngStatus = CommSetLine(intPortID, LINE_RTS, True)
    lngStatus = CommSetLine(intPortID, LINE_DTR, True)

    ' Write data to serial port.
    lngSize = Len(strData)
    lngStatus = CommWrite(intPortID, strData)
    If lngStatus <> lngSize Then
    ' Handle error.
    End If

Where do I go wrong????

Dear all Experts!
I would like to thank you all for assisting me to almost finish my task as assigned by management, and many special thanks to Mr Jim for providing the VBA code below for send & receiving data from & to RS232 com gadget
The last bit though not much is another assistance required to receive the data from RS 232 which is coming in Json format, I’m fully aware he also provided a form on the scale part, but this appear to be slightly different:
