i am currently trying to edit a pdf with hummus.js to replace certain placeholder characters in the pdf with others.
This works perfectly fine for almost every page, but for certain pages I get the following error:
TypeError:
pageObject.getDictionary(...).toJSObject(...).Contents.getObjectID is
not a function for:
const textObjectID = pageObject.getDictionary().toJSObject().Contents.getObjectID();
Whenever that error happens and it doesnt work,
pageObject.getDictionary().toJSObject().Contents returns a PDFArray {}, while, when it works, it returns an PDFIndirectObjectReference {}
Does anybody know how I could solve this issue or any other way to edit a pdf that way (replacing certain placeholder characters with others)
UPDATE 1: I can now differentiate between IndirectObjectReferences and arrays containing IndirectObjectReferences, but for some reason it removes all text but keeps the images from pdf pages which i access through these arrays, the rest of the pdf pages still work perfectly fine
async function replacetext(filePath, callback) {

I tried to send my variable back from foreground.js to background.js by using an unchanged variable, and it works. Now I can't send some data that I use my AddEventListener syntax to store the data into the variable to call its back to background.js here are my code on foreground.js
foreground.js
console.log("foreground.js injected");
var pswdBtns = [];
let hrefLists = [];
var data = {};
var i;
function readUUID(){
var navigator_info = window.navigator;
var screen_info = window.screen;
var uid = navigator_info.mimeTypes.length;
uid += navigator_info.userAgent.replace(/\D+/g, '');
uid += navigator_info.plugins.length;
uid += screen_info.height || '';
uid += screen_info.width || '';
uid += screen_info.pixelDepth || '';
return uid;
}
async function passwordProtected(pointerList){
const date = new Date();
const uid = readUUID();
alert("You are in dangerous on \'"+ pointerList.title + "\' row = " + pointerList.id.slice(20));
data = {
"Webtitle": pointerList.href,
"Title": pointerList.title,
"Time": date.toString(),
"UUID": uid
}
console.log("foreground = ", data);
return data;
}
console.log("Start loop")
//This function made for collect each id in passwordShowPasswordButton
for(i = 0; i<=pswdBtns.length; i++){
if(document.querySelector("#passwordShowPasswordButton_"+ i) == null){
console.log("This is your limit!!");
}
else{
hrefLists[i] = document.querySelector("#passwordWebsitelink_"+ i);
pswdBtns[i] = document.querySelector("#passwordShowPasswordButton_"+ i);;
data = pswdBtns[i].addEventListener('click', passwordProtected.bind(pswdBtns[i], hrefLists[i]));
console.log(hrefLists[i].title); /* Title VARCHAR(30) */
console.log(hrefLists[i].href); /* Website VARCHAR(50) */
}
}
console.log("End");
and these are my code on background.js
background.js
const edgePswd = "edge://settings/passwords";
const settingPage = "edge://settings/";
chrome.tabs.onActivated.addListener(async (tab) => {
await chrome.tabs.get(tab.tabId, (current_tab_info) => {
var pswdPageChecked = 1;
while(pswdPageChecked < 2) {
if (edgePswd == current_tab_info.url) {
chrome.tabs.executeScript(null, { file: "/extension/foreground.js" }, (data) => {
console.log("Coming to foreground");
console.log(data);
});
pswdPageChecked++;
}
}
});
});
It would be a pleasure if someone can figure this.
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

I want to export the current google sheet data into pdf page but I do want a page break at row 10 so that any data after row 10 goes on to the next page. This means there will be multiple pages for more data. I do not want to print all data on one page. The final pdf file should have multiple pages for data that crosses row 10 in the google sheet

I developed an example script to test the approach described in my comment. I'll leave it here for future reference, but feel free to leave a comment if you have any doubt about it. This is the final script:
function exportRowsToPDF() {
var importantRows = [2, 13, 14, 15, 19]; // Exported rows
var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
var originalSheet = SpreadsheetApp.getActiveSheet();
var sheets = spreadsheet.getSheets();
var tempSheet = spreadsheet.insertSheet("TEMP", 10);
var maxColumn = originalSheet.getLastColumn();
for (var i = 0; i < importantRows.length; i++) {
tempSheet.appendRow(originalSheet.getRange(importantRows[i], 1, 1, maxColumn)
.getValues()[0]);
}
for (var i = 0; i < sheets.length; i++) {
if (sheets[i].getSheetName() !== "TEMP") {
sheets[i].hideSheet();
}
}
DriveApp.createFile(spreadsheet.getBlob().setName("Exported Sheet"));
for (var i = 0; i < sheets.length; i++) {
sheets[i].showSheet();
}
spreadsheet.deleteSheet(tempSheet);
}
You can modify the script to export any particular rows, but I used five of them for testing. This script will create a new sheet on your spreadsheet, and it will copy any relevant row there. Then, it will hide every sheet minus the newly created one. After that it will export the spreadsheet as a PDF blob directly to your Drive. Finally, it will reset the spreadsheet to the original state (by removing the created sheet and unhiding every other sheet). This code uses the same methods as your example, but write to me if you want to clarify any point.
I want to create an application that allows a user to join multiple video call rooms in kurento.
I wrote the following code:
function joinRooms() {
var userId = document.getElementById('expertid').value;
console.log("UserID = " + userId);
var roomIds = document.getElementById('roomids').value.split(",");//Assume that we have 2 rooms r1 & r2
var userIdAlias = [];
for (var i = 0; i < roomIds.length; i++) {
userIdAlias[i] = userId + "(" + i + ")";
console.log("User alias = " + userIdAlias[i]);
}
var wsUri = 'wss://' + location.host + '/room';
kurento = KurentoRoom(wsUri, function(error, kurento) {
if (error)
return console.log(error);
for (let i = 0; i < roomIds.length; i++) {
//console.log("Start loop Roomid = " + roomId);
rooms[i] = kurento.Room({
room : roomIds[i],
user : userIdAlias[i],
subscribeToStreams : true
});
localStreams[i] = kurento.Stream(rooms[i], {
audio : true,
video : true,
data : true
});
localStreams[i].addEventListener("access-accepted", function() {
var playVideo = function(stream) {
var participantId = stream.getParticipant().getID();
var userId = document.getElementById('expertid').value;
console.log("userId = " + userId + ", participantId = " + participantId);
if (!userIdAlias.includes(participantId)) {
var elementId = "video-" + stream.getGlobalID();
var div = document.createElement('div');
div.setAttribute("id", elementId);
document.getElementById("participants").appendChild(div);
stream.playThumbnail(elementId);
// Check color
var videoTag = document.getElementById("native-" + elementId);
var userId = stream.getGlobalID();
var canvas = document.createElement('CANVAS');
checkColor(videoTag, canvas, userId);
}
}
rooms[i].addEventListener("room-connected", function(){
var j = i;
return function(roomEvent) {
document.getElementById('room-header').innerText = 'ROOM \"'
+ roomIds[j] + '\"';
//document.getElementById('join').style.display = 'none';
document.getElementById('room').style.display = 'block';
localStreams[j].publish();
var streams = roomEvent.streams;
for (var streamsIdx = 0; streamsIdx < streams.length; streamsIdx++) {
playVideo(streams[streamsIdx]);
}
}
});
rooms[i].addEventListener("stream-added", function(streamEvent) {
playVideo(streamEvent.stream);
});
rooms[i].addEventListener("stream-removed", function(streamEvent) {
var element = document.getElementById("video-"
+ streamEvent.stream.getGlobalID());
if (element !== undefined) {
element.parentNode.removeChild(element);
}
});
playVideo(localStreams[i]);
rooms[i].connect();
});
localStreams[i].init();
}
});
}
However, the code does not work. The log in server said that there is only one user request to join room r2 but not r1.
I think the reason is Javascript works with too many asynchronous task so it worked incorrectly.
Can you give some advice about the way to joining multiple rooms in kurento?

Using above code i can able to go through the selected messages.but not saving the attachments.its showing number of attachments.
And also i would like to set my own labels for the selected mails. How i can i achieve this? Please help me out... Thanks in advance
working code
var enumerator = gFolderDisplay.selectedMessages;
for each (var msgHdr in fixIterator(enumerator, Components.interfaces.nsIMsgDBHdr)) {
msgHdr.setStringProperty("docuHive","dhivelabel");
MsgHdrToMimeMessage(msgHdr, null, function (aMsgHdr, aMimeMsg) {
try {
var attachments = aMimeMsg.allUserAttachments || aMimeMsg.allAttachments;
for (var [index, att] in Iterator(attachments))
{
var ioService = Components.classes["#mozilla.org/network/io-service;1"].getService(Components.interfaces.nsIIOService);
var neckoURL = null;
neckoURL = ioService.newURI(att.url, null, null);
neckoURL.QueryInterface(Components.interfaces.nsIMsgMessageUrl);
var uri = neckoURL.uri;
var attInfo = new AttachmentInfo(att.contentType, att.url, att.name, uri, att.isExternal);
// getting the chrome directory
var file = Components.classes["#mozilla.org/file/directory_service;1"].
getService(Components.interfaces.nsIProperties).
get("AChrom", Components.interfaces.nsIFile);
var msguri = msgHdr.folder.getUriForMsg(msgHdr);
messenger = Components.classes["#mozilla.org/messenger;1"]
.createInstance(Components.interfaces.nsIMessenger);
alert(messenger);
messenger.saveAttachmentToFolder(att.contentType,att.url,"attachmentname.extension",msguri,file);
}
} catch (err) {
alert(err);
}
}, true, { examineEncryptedParts: true, });
