Am using Fck editor to write content. Am storing the text as versions in db. I want to highlight those changes in versions when loading the text in FCK Editor.
How to compare the text....
How to show any text that has been deleted in strike through mode.
Please help me/...
Try google's diff-patch algorithm http://code.google.com/p/google-diff-match-patch/
Take both previous and current version of the text and store it into two parameters. Pass the two parameters to the following function.
function diffString(o, n) {
o = o.replace(/<[^<|>]+?>| /gi, '');
n = n.replace(/<[^<|>]+?>| /gi, '');
var out = diff(o == "" ? [] : o.split(/\s+/), n == "" ? [] : n.split(/\s+/));
var str = "";
var oSpace = o.match(/\s+/g);
if (oSpace == null) {
oSpace = ["\n"];
} else {
oSpace.push("\n");
}
var nSpace = n.match(/\s+/g);
if (nSpace == null) {
nSpace = ["\n"];
} else {
nSpace.push("\n");
}
if (out.n.length == 0) {
for (var i = 0; i < out.o.length; i++) {
str += '<span style="background-color:#F00;"><del>' + escape(out.o[i]) + oSpace[i] + "</del></span>";
}
} else {
if (out.n[0].text == null) {
for (n = 0; n < out.o.length && out.o[n].text == null; n++) {
str += '<span style="background-color:#F00;"><del>' + escape(out.o[n]) + oSpace[n] + "</del></span>";
}
}
for (var i = 0; i < out.n.length; i++) {
if (out.n[i].text == null) {
str += '<span style="background-color:#0C0;"><ins>' + escape(out.n[i]) + nSpace[i] + "</ins></span>";
} else {
var pre = "";
for (n = out.n[i].row + 1; n < out.o.length && out.o[n].text == null; n++) {
pre += '<span style="background-color:#F00;"><del>' + escape(out.o[n]) + oSpace[n] + "</del></span>";
}
str += " " + out.n[i].text + nSpace[i] + pre;
}
}
}
return str;
}
this returns an html in which new text is marked green and deleted text as red + striked out.

I'm trying to get data from a website that does not have an API documentation. I used selenium to login and navigate. Today I found the data I need, it appears after a post request.
There's any way I can get the exact post parameters to do it in my node program?
Data I need
edit 1:
the code that works from console browser scrap the data from the page and save a csv file:
const timeElapsed = Date.now();
const today = new Date(timeElapsed);
let updateTime;
let dataStudents = "";
let anoSerie;
let turma;
let prova;
let disciplina;
class AlunoProva {
constructor(nome, Status, anoSerie, turma, prova, disciplina, modalidadeEnsino, data) {
this.nome = nome;
this.Status = Status;
this.anoSerie = anoSerie;
this.turma = turma;
this.prova = prova;
this.disciplina = disciplina;
this.modalidadeEnsino = modalidadeEnsino;
this.data = data;
}
}
var saveData = (function () {
var a = document.createElement("a");
document.body.appendChild(a);
a.style = "display: none";
return function (data, fileName) {
blob = new Blob([data], { type: "ext/csv;charset=utf-8;" }),
url = window.URL.createObjectURL(blob);
a.href = url;
a.download = fileName;
a.click();
window.URL.revokeObjectURL(url);
};
}());
const atualState = "Finalizado - Digital, Não iniciado, Em progresso - Digital"
function getTurma() {
let Turma = prompt("Informe a letra da turma atual", "A");
while (Turma == null || Turma == "") {
alert("Truma inválida! Por favor, informe uma turma válida.");
Turma = prompt("Informe a letra da turma atual", "A");
}
return Turma;
}
turma = getTurma().toUpperCase();
function getCombo(id) {
let combo = document.getElementById(id);
let dataComboSelected = combo.options[combo.selectedIndex].text;
return dataComboSelected;
}
String.prototype.hashCode = function () {
var hash = 0, i, chr;
if (this.length === 0) return hash;
for (i = 0; i < this.length; i++) {
chr = this.charCodeAt(i);
hash = ((hash << 5) - hash) + chr;
hash |= 0; // Convert to 32bit integer
}
return hash;
};
let aluno = new AlunoProva()
function dataMount(data) {
if (data !== "ESTUDANTE" && data !== "PARTICIPAÇÃO")
if (!atualState.includes(data)) {
aluno.nome = data;
dataStudents += data + ",";
}
else {
aluno.Status = data;
dataStudents += data + ",";
aluno.anoSerie = anoSerie;
dataStudents += anoSerie + ","
aluno.turma = turma;
dataStudents += turma + ","
aluno.prova = prova;
dataStudents += prova + ","
aluno.disciplina = disciplina;
dataStudents += disciplina + ","
if (anoSerie.includes("EF")) {
aluno.modalidadeEnsino = "Fundamental";
dataStudents += "Fundamental,"
}
else {
aluno.modalidadeEnsino = "Médio";
dataStudents += "Médio,"
}
aluno.data = today.toLocaleDateString();
dataStudents += today.toLocaleDateString() + "\n"
}
}
prova = getCombo('selectnn74f9d641c4DADOS.VL_FILTRO_AVALIACAO')
disciplina = getCombo('select3lw7fc885326DADOS.VL_FILTRO_DISCIPLINA')

Array.from($$("body table tr *")).forEach((el) => {

if (el.indexOf('Atualizado') === 0) {

}
});
let hashname = (anoSerie + turma + prova + disciplina + JSON.stringify(today.toLocaleDateString())).toString();

I'm having a problem with selectors on node, just rebember that I'm not conected with the site, I'm simulating a navigation with selenium. All the frameworks I checked to help me with selectors needed that I provide an url, but I can't, the only way I found to enter the system is from selenium navigation to simulating a real user.
I would like to display some ascii art in this format:
_,-, Name: Powerful Axe
T_ | Rarity: Yellow Rarity (77.5)
||`-' Attack: 100
|| Defense: 100
|| Speed: 100
~~ Gold Value: 10
an axe that is really rare
I want it in a column layout, kind of like neofetch does, but in NodeJS.
I get all this data from a json file, and I am using the following function to format and color the key pair type values:
const chalk = require('chalk')
function keyValue(key, value) {
return chalk.green(key) + ": " + chalk.yellow(value)
}
This all needs to be in the terminal, and preferably not using node-curses or blessed.
I found a very inefficient and bloated solution:
function print2MultiLine(string, string2) {
var arr1 = string.split("\n");
var arr2 = string2.split("\n");
if (arr1.length > arr2.length) {
while (arr1.length > arr2.length) {
arr2.push("");
}
} else if (arr1.length < arr2.length) {
while (arr1.length < arr2.length) {
arr1.push("");
}
}
var longestLine = 0;
for (let i = 0; i < arr1.length; i++) {
if (arr1[i].length > longestLine) {
longestLine = arr1[i].length;
}
}
for (let i = 0; i < arr1.length; i++) {
while (arr1[i].length < longestLine) {
arr1[i] += " ";
}
}
for (let i = 0; i < arr1.length; i++) {
console.log(arr1[i] + " " + arr2[i]);
}
}
if you like comments:
function print2MultiLine(string, string2) {
// for each line in each string, print it out 3 spaces away from the other
var arr1 = string.split("\n");
var arr2 = string2.split("\n");
// if one string is longer than the other, make the shorter one the length of the longer one
if (arr1.length > arr2.length) {
while (arr1.length > arr2.length) {
arr2.push("");
}
} else if (arr1.length < arr2.length) {
while (arr1.length < arr2.length) {
arr1.push("");
}
}
// get the length of the longest line in arr1
var longestLine = 0;
for (let i = 0; i < arr1.length; i++) {
if (arr1[i].length > longestLine) {
longestLine = arr1[i].length;
}
}
// make all other lines in arr1 the length of the longest line
for (let i = 0; i < arr1.length; i++) {
while (arr1[i].length < longestLine) {
arr1[i] += " ";
}
}
// print out the strings
for (let i = 0; i < arr1.length; i++) {
console.log(arr1[i] + " " + arr2[i]);
}
}

I am trying the approach below. It is based on some of Uniswap's code.
I am curious as to whether it will work at reasonable cost or whether there is a better way.
function escapeHTML(string memory input)
public
pure
returns (string memory)
{
bytes memory inputBytes = bytes(input);
uint extraCharsNeeded = 0;
for (uint i = 0; i < inputBytes.length; i++) {
bytes1 currentByte = inputBytes[i];
if (currentByte == "&") {
extraCharsNeeded += 4;
} else if (currentByte == "<") {
extraCharsNeeded += 3;
} else if (currentByte == ">") {
extraCharsNeeded += 3;
}
}
if (extraCharsNeeded > 0) {
bytes memory escapedBytes = new bytes(
inputBytes.length + extraCharsNeeded
);
uint256 index;
for (uint i = 0; i < inputBytes.length; i++) {
if (inputBytes[i] == "&") {
escapedBytes[index++] = "&";
escapedBytes[index++] = "a";
escapedBytes[index++] = "m";
escapedBytes[index++] = "p";
escapedBytes[index++] = ";";
} else if (inputBytes[i] == "<") {
escapedBytes[index++] = "&";
escapedBytes[index++] = "l";
escapedBytes[index++] = "t";
escapedBytes[index++] = ";";
} else if (inputBytes[i] == ">") {
escapedBytes[index++] = "&";
escapedBytes[index++] = "g";
escapedBytes[index++] = "t";
escapedBytes[index++] = ";";
} else {
escapedBytes[index++] = inputBytes[i];
}
}
return string(escapedBytes);
}
return input;
}
How can I concatenate my String and the int in the lines:
print('Computer is moving to ' + (i + 1));
and print("Computer is moving to " + (i + 1));
I cant figure it out because the error keeps saying "The argument type 'int' can't be assigned to the parameter type 'String'
void getComputerMove() {
int move;
// First see if there's a move O can make to win
for (int i = 0; i < boardSize; i++) {
if (_mBoard[i] != humanPlayer && _mBoard[i] != computerPlayer) {
String curr = _mBoard[i];
_mBoard[i] = computerPlayer;
if (checkWinner() == 3) {
print('Computer is moving to ' + (i + 1));
return;
} else
_mBoard[i] = curr;
}
}
// See if there's a move O can make to block X from winning
for (int i = 0; i < boardSize; i++) {
if (_mBoard[i] != humanPlayer && _mBoard[i] != computerPlayer) {
String curr = _mBoard[i]; // Save the current number
_mBoard[i] = humanPlayer;
if (checkWinner() == 2) {
_mBoard[i] = computerPlayer;
print("Computer is moving to " + (i + 1));
return;
} else
_mBoard[i] = curr;
}
}
}
With string interpolation:
print("Computer is moving to ${i + 1}");
Or just call toString():
print("Computer is moving to " + (i + 1).toString());
You can simply use .toString which will convert your integer to String :
void main(){
String str1 = 'Welcome to Matrix number ';
int n = 24;
//concatenate str1 and n
String result = str1 + n.toString();
print(result);
}
And in your case it's gonna be like this :
print("Computer is moving to " + (i + 1).toString());
I'm facing a problem with my code... I make a query to my DB to check if a mac address of a array of macs is on the DB. If I have any result I return the count of macs in my DB and if is > 0 then I don't add nothing cause the mac already is listed, but if my result.count = 0 then I will add a new record.
My new record just have the mac address. For this I'm trying:
var countRepetidos = 0
var countPromises = []
if (obj.data.list != {} && obj.data.list.length > 0) {
var aux = obj.data["list"]
countRepetidos = 0
for (var i = 0; i < aux.length; i++) {
countPromises.push(Database.Probing.getMacAdress(aux[i]).then(function(data) {
console.log("probing countPromises aux[i] ", aux[i])
if (data.count > 0) {
countRepetidos += 1
} else {
Database.Probing.addMac(aux[i])
}
return Promise.resolve()
}))
}
Promise.all(countPromises).then(() => {
dataRepeated = [obj.data.stats.since, countRepetidos]
listaRepeated.push(dataRepeated)
console.log("probing listaRepeated --> ", listaRepeated)
if (listaRepeated != [] && (listaRepeated[0][0] != undefined && listaRepeated[0][1] != undefined)) {
Database.Probing.getLastTimestamp("probing_repeated", device.id).then(function(data) {
var lastTimestamp = data.date_part
console.log('probing lastTimestamp ', lastTimestamp * 1000)
if (lastTimestamp != listaRepeated[0][0] / 1000) {
Controllers.Agregate.agregateData("probing_repeated", 5 * 60, listaRepeated, dbHistConnectionString, device.id, device.network_id, device.organization_id, ["time", "clients"])
}
})
}
})
}
The problem is after the then of Database.Probing.getMacAddress my aux[i] gets undefined and I need this value to insert into my DB.
Anyone can help?
You need to preserve the value of i. You can do this way:
for (var i = 0; i < aux.length; i++) {
(function(i) {
countPromises.push(
Database.Probing.getMacAdress(aux[i]).then(function(data) {
console.log("probing countPromises aux[i] ", aux[i])
if (data.count > 0) {
countRepetidos += 1
} else {
Database.Probing.addMac(aux[i])
}
return Promise.resolve()
}))
})(i)
}
Edit 1: As suggested by #lain, use let over var
for (let i = 0; i < aux.length; i++) {}
