Delay for messages in node-telegram-bot-api

I am working on a telegram bot with the node-telegram-bot-api library. I made 2 buttons using keyboard. But when you click on them a lot, the bot will spam and sooner or later it will freeze. Is it possible to somehow put a delay for the user on messages.
if (text === '/start') {
return bot.sendMessage(chatId, 'hello', keyboardMain);
}
export const keyboardMain = {
reply_markup: JSON.stringify({
keyboard: [
[{
text: '/start',
},
],
resize_keyboard: true
})
};

You can create a user throttler using Javascript Map
/*
* #param {number} waitTime Seconds to wait
*/
function throttler(waitTime) {
const users = new Map()
return (chatId) => {
const now = parseInt(Date.now()/1000)
const hitTime = users.get(chatId)
if (hitTime) {
const diff = now - hitTime
if (diff < waitTime) {
return false
}
users.set(chatId, now)
return true
}
users.set(chatId, now)
return true
}
}
How to use:
You'll get the user's chatId from telegram api. You can use that id as an identifier and stop the user for given specific time.
For instance I'm gonna stop the user for 10seconds once the user requests.
// global 10 second throttler
const throttle = throttler(10) // 10 seconds
// in your code
const allowReply = throttle(chatId) // chatId obtained from telegram
if (allowReply) {
// reply to user
} else {
// dont reply
}

I tried using this code, put the function code in my function file, connected everything to the required file, and I don’t understand what to do next and where to insert the last code and what to do with it. I'm new to JavaScript and just learning.
import {
bot
} from '../token.js';
import {
throttler
} from '../functions/functions.js';
import {
keyboardMain
} from '../keyboards/keyboardsMain.js';
export function commands() {
bot.on('message', msg => {
const text = msg.text;
const chatId = msg.chat.id;
const throttle = throttler(10);
if (text === '/start') {
const allowReply = throttle(chatId) // chatId obtained from telegram
if (allowReply) {
return bot.sendMessage(chatId, 'hello', keyboardMain);
} else {
// dont reply
}
}
return bot.sendMessage(chatId, 'error');
});
}
Get the time when he pressed the button
Get the time of the next click
Take away the difference and set the condition (if, for example, more than 3 seconds have passed between clicks, then the user will not be frozen).

var token = ""; // FILL IN YOUR OWN TOKEN
var telegramUrl = "https://api.telegram.org/bot" + token;
var webAppUrl = ""; // FILLINYOUR GOOGLEWEBAPPADDRESS
var ssId = ""; // FILL IN THE ID OF YOUR SPREADSHEET
function getMe() {
var url = telegramUrl + "/getMe";
var response = UrlFetchApp.fetch(url);
Logger.log(response.getContentText());
}
function setWebhook() {
var url = telegramUrl + "/setWebhook?url=" + webAppUrl;
var response = UrlFetchApp.fetch(url);

}

return HtmlService.createHtmlOutput("Hi there");
}

Is this the correct way

Javascript replace string function

I have a script I'm trying to write which takes a string and finds the dmcode then sends it to a function to format it correctly then returns the value. This seems to work but I can't get the replace function to work on the string calling it. This has got to be easy but everything I've tried has resulted in errors.
Your help is appreciated.
Max
function scrubDMC(DM){
var dmcode = DM;
for (var i = 0; i < dmcode.length; i++) {
DMC = dmcode[i];
match = DMC.match(/modelIdentCode="(.*?)"/im);
if (match !== null) {
var modelIdentCode = match[1];
}
match = DMC.match(/systemDiffCode="(.*?)"/im);
if (match !== null) {
var systemDiffCode = match[1];
}
match = DMC.match(/\ssubSystemCode="(.*?)"/im);
if (match !== null) {
var subSystemCode = match[1];
}
match = DMC.match(/subSubSystemCode="(.*?)"/im);
if (match !== null) {
var subSubSystemCode = match[1];
}
}
var sFileName = "DMC-" + modelIdentCode +"-"+ systemDiffCode +"-"+ systemCode + "-" + subSystemCode + subSubSystemCode + "-" + assyCode +"-"+ disassyCode + disassyCodeVariant +"-" + infoCode +infoCodeVariant +"-" +itemLocationCode;
console.log("sFileName : " + sFileName);
return sFileName;
}
Code calling the function that isn't working
var readyWarn2 = readyWarn.replace(/<symbol infoEntityIdent=".*?"\/>/ig, "");
var dmcode = readyWarn2.match(/<dmcode.*?>/ig);
scrubDMC(dmcode);
readyWarn2.replace(dmcode, sFileName);

Your last line needs to be
readyWarn2 = readyWarn2.replace(dmcode, sFileName);
Javascript strings can't be changed, so String.replace() returns a new string value.

How to set a cookie that prevents further javascript alerts?

I have this code for detecting android:
var mobile = (/android/i.test(navigator.userAgent.toLowerCase()));
if (mobile){
alert("Message to android users");
}
...but how do I get that script to also set a cookie so the android user doesn't continue getting the alert (either on reloading the page, returning later to the page, or navigating to other pages which have the alert)?
I also have this, which uses a cookie to avoid a user viewing a "welcome page" they've already seen:
var RedirectURL = "http://www.example.com/real-home-page.html";
var DaysToLive = "365";
var CookieName = "FirstVisit";
function Action() {
location.href = RedirectURL;
}
DaysToLive = parseInt(DaysToLive);
var Value = 'bypass page next time';
function GetCookie() {
var cookiecontent = '';
if(document.cookie.length > 0) {
var cookiename = CookieName + '=';
var cookiebegin = document.cookie.indexOf(cookiename);
var cookieend = 0;
if(cookiebegin > -1) {
cookiebegin += cookiename.length;
cookieend = document.cookie.indexOf(";",cookiebegin);
if(cookieend < cookiebegin) { cookieend = document.cookie.length; }
cookiecontent = document.cookie.substring(cookiebegin,cookieend);
}
}
if(cookiecontent.length > 0) { return true; }
return false;
}
function SetCookie() {
var exp = '';
if(DaysToLive > 0) {
var now = new Date();
then = now.getTime() + (DaysToLive * 24 * 60 * 60 * 1000);
now.setTime(then);
exp = '; expires=' + now.toGMTString();
}
document.cookie = CookieName + '=' + Value + exp;
return true;
}
if(GetCookie() == true) { Action(); }
SetCookie();
Can the second script be adapted and combined into the first to do something like:
function Action() {
don't-open-that-alert-again;
I've googled and found some js cookie scripts, but all over 100K. Prefer something as succinct as the above.

Update/Replace output text onClick - replaceNodes - Javascript

I have a form that takes information and outputs it in a div if its complete. If the form is not complete, output is error messages relating to the specific field which needs correcting. The error messages/output update as information is changed and the button is clicked.
Currently valid output will update as it changes, but going between valid output and error messages, the two sets of text both appear on the page, and then remain there until I refresh the page. Here's the code:
/*
Project 1 - AJAX 2015

*/
/*
Function to create input and HTML elements,
Create output nodes; output div
*/
function init() {
//Output Div
var div = document.createElement("div");
div.id = "output";
//Name
var name = document.getElementById("name").value;
name.type = "text";

div.appendChild(br());
div.appendChild(printName);

div.appendChild(printGender);
div.appendChild(br());
div.appendChild(printCourses);
div.appendChild(br());
var output = document.getElementById("output");
if (output) {
output.parentNode.replaceChild(div, output);
} else {
document.body.appendChild(div);
}
}
I would like for only the current accurate messages to appear, either errors or valid output, not both. My element-replacing logic seems to be off. I am not using jQuery or innerHTML for this project. Please advise.

How to add name value pair to existing query string

i need to add new name ,value pair to existing query string when the user click on some button.
i'm using jquery for client side operations.
any idea..?
thank in advance!

You could do:
$('#yourId').click(function(){
var href = window.location.href;
var indexOfCanc = href.indexOf('#');
if(indexOfCanc === -1){
if(href.indexOf('?') === -1){
href+="?newparamter=my";
}else{
href+="&newparamter=my";
}
}else{
var newHref = href.substring(0, indexOfCanc);
var locationHash = href.substring(indexOfCanc);
if(href.indexOf('?') === -1){
newHref += "?newparamter=my"+locationHash;
}else{
newHref += "&newparamter=my"+locationHash;
}
}
//use the new href for example reload the page with the new parameter:
window.location.href = href;
});

Using regExp:
var href = window.location.href,
toAdd,
pattern1 = /\?/gi,
pattern2 = /#/gi;
if (href.match(pattern1) != null) { toAdd = "&" }
else { toAdd = "?" }
toAdd += "param=val";
if (href.match(pattern2) != null) {
var arr = href.split('#');
href = arr[0] + toAdd + '#' + arr[1];
}
else { href += toAdd; }
