Same question as below with different wording. Which line errors and what error?

greeting : (message) => console.log(message + " "+ this.name())
^

The "function" version works so just use it.

let person = {
firstName: "John",
lastName : "Doe",
id : 5566,
fullName : function() {
return this.firstName + " " + this.lastName;
}
}
console.log(person.fullName())
When I am using arrow function here then I am getting undefined undefined as my output. Could anyone please let me know why this is happening. Below is my code with arrow function.
let person = {
firstName: "John",
lastName : "Doe",
id : 5566,
fullName : () => {
return this.firstName + " " + this.lastName;
}
}
console.log(person.fullName())

Arrow functions do not have access to this. They are not meant to be used the way you are doing here.

I am in the process of building a website in Squarespace, I am using Javascript to create a multi-lingual website in English and French. I differentiate between English and French using the URL/Slug
Example
www.websitename.com/en/home
or
www.websitename.com/fr/home
Everything is translating, almost. I am having issues with the footer translating.

Just debug your code and figure out what you're doing wrong. Should be pretty simple.

For Numbers and BigInts toString() takes an optional parameter radix the value of radix must be minimum 2 and maximum 36.
By using radix you can also convert base 10 numbers (like 1,2,3,4,5,.........) to another base numbers, in example below we are converting base 10 number to a base 2 (binary) number ...
So your entire series of if (value >= ...) blocks can be replaced with a single call to toString, along with a call to padStart[^] to add any leading zeros:
value = alphabet.indexOf(text[letter].toUpperCase()) + 1;
binary += value.toString(2).padStart(5, "0");

I am using npm module xlsx to write and read JSON data.
I want to write this JSON to excel
{ "name": "John", "class": 1, "address" : [ { "street": "12th Cross" , "city": "London" }, { "street": "22nd Cross" , "city": "Cade" } ] }
Later when I read back I want to get same JSON from excel file
If you already solved, any suggestion or help will be of great help 
Here is what I have tried
```
var XLSX = require("xlsx");
console.log("Node Version: " + process.versions.node);
console.log("XLSX Version: " + XLSX.version);
/* GENERATE TEST FILE */
(function() {
// create workbook
var wb = XLSX.utils.book_new();
var ws = XLSX.utils.json_to_sheet([
{ "name": "John", "class": 1, "address" : [ { "street": "12th Cross" , "city": "London" }, { "street": "22nd Cross" , "city": "Cade" } ] }
], {header:["name","class","address","street","city"]});
XLSX.utils.book_append_sheet(wb, ws, "Sheet1");
XLSX.writeFile(wb, "testfile.xlsx");
let worksheet = wb.Sheets['Sheet1'];
let jsonArray= XLSX.utils.sheet_to_json(worksheet);
console.log(JSON.stringify(jsonArray));
})();
```
This returns
```
Node Version: 8.12.0
XLSX Version: 0.16.2
[{"name":"John","class":1}]
But I was expecting
{ "name": "John", "class": 1, "address" : [ { "street": "12th Cross" , "city": "London" }, { "street": "22nd Cross" , "city": "Cade" } ] }
```
Any help or suggestion will be of great help

I am creating a program where if an action occurs then a message box through visual basic script (.vbs). I plan to do I through a fstream file.

I think that this one is a bit misplaced in the "Javascript" section

Unless things have changed, only IE will support running vb script files which means this won't work in FireFox, Chrome, or any other browser, probably not even Edge.
But you are writing this in C++ so I am confused as to what you are actually doing. How and why does vbs come into play with C++ code?

You need to ask a specific question. It is rude to ask someone to do all your work for you.

a newbie here...
I have an accordion that's content is being brought in through includes. The accordion is showing up but with all the tabs in the open position and they won't toggle open/close. I'm completely stuck on how to get these to work with the accordion content being brought in dynamically.
This is the code that works on the normal content accordions:
(function($, window, document, undefined) {
'use strict';
$(document).ready(function() {
var $container_class = $('.accordions');
var $default_class = $('.beefup');
var $toggle_buttons_class = $('.toggle-buttons');
var $default_options = {
openSingle: true,
openSpeed: 300,
closeSpeed: 300
};
if ($container_class.length) {
$container_class.each(function() {
if ($default_class.length) {
$(this).find($default_class).beefup($default_options);
}
});
}
if ($toggle_buttons_class.length) {
$toggle_buttons_class.each(function() {
var $this = $(this);
var $beefup = $this.find($default_class).beefup($default_options);
$this.find('.toggle-open-all').on('click', function() {
$beefup.open();
});
$this.find('.toggle-close-all').on('click', function() {
$beefup.close();
});
$this.find('.buttons-group').find('.button').each(function(index) {
$(this).on('click', function() {
if (!$(this).hasClass('toggle-open-all') && !$(this).hasClass('toggle-close-all')) {
$this.find($container_class).find($default_class).each(function(item) {
if (index === item) {
$beefup.click($(this));
}
});
}
});
});
});
}
The classes are different for the dynamic accordion, I tried to change them in a duplicated section of this JS, but no luck.
The page if wish to view is here: http://clear-talk.oiw11.com/motorola/bpr40.htm It's the section towards the bottom of the page under the "accessories" tab.
I'm wondering if there's a better/easier way to go about this.
Any and all help would be greatly appreciated.
Thank you in advance!

I have a page where values (monetary) are entered into boxes and the aim is to have them appear in a drop down list on the next page. I have searched and found this Transferring page values to another page[^] But wondered if there was a more upto date way of doing it?
I have the code below and whilst I can send the data to the URL the script doesn't put it in the drop down. I've read about doing it with cookies, is that a more reliable method?
<script>
from the url as a query string
var query = location.search;
var splitQuery = []; var value
= [];
function parseQuery(query){
if(query.search(/[&]/)){
splitQuery = query.split('&');
for (var x = 0; x <
splitQuery.length; x++){
var splitEach =
splitQuery[x].split('=');
document.getElementsByClassName
('dropdown')[x].textContent =
splitEach[1];
}
}
}
parseQuery(query);
</script>

So long as you don't need to support Internet Explorer, the modern way to parse the querystring is to use the URLSearchParams class:
URLSearchParams - Web APIs | MDN[^]
const searchParams = new URLSearchParams(location.search);
for (const [key, value] of searchParams) {
console.log(key, "=", value);
} It's not clear what the connection is between the querystring parameters and the form parameters, but the code you've shown requires that they're in exactly the same order. It would probably be better if you could match based on the name of the element.
You'll also need to use the value property, not the textContent property, to set the value for a form element.
const searchParams = new URLSearchParams(location.search);
for (const [key, value] of searchParams) {
let element = document.getElementsByName(key)[0];
if (element && element.classList.contains("dropdown") && (/^INPUT|SELECT$/i).test(element.tagName)) {
element.value = value;
}
else {
console.warn("Unknown element:", key, element);
}
}
