I can't figure out how to do nested commands for Nightmare. Consider the following code:
let userLinks = await nightmare.evaluate(function(users, nightmare) {
for(var i = 0; i < users.length; i++) {
var matchResult = users[i].match(/.com\/(.*?)\?fref/);
if (matchResult) {
var newLink = document.createElement('a');
document.body.appendChild(newLink);
newLink.setAttribute('href', 'https://www.example.com/'+matchResult[1]);
nightmare.click('a[href="https://www.example.com/'+matchResult[1]+'"]'); // this won't work
}
}
return null;
}, users);
The nightmare.click() won't work. I get nightmare.click is not a function. How can this be done?

I have the following script that I need to adjust so that each iteration has a one second pause before or after it executes the loop (it doesn't really matter which as long as the lag is there). I tried to add the setTimeout() function into the Try section of my code but it is still consistently failing. I also have tried to use "let" instead of "var" in the for loop but that failed as well. Any advice on how to add it in would be very appreciated. I'm having trouble finding an example of a similar setTimeout() function within a for loop online.
var ZB_DataExtension = 'C7_Unsubscribe_Response';
var ZB_DataExtension_Response = 'C7_Unsubscribe_Response';
var ZB_DataExtension_Logs = 'C7_CustUnsubscribe_Logs';
//Endpoint
var zeroBounceFullUrl = 'https://api.commerce7.com/v1//customer/CUST_ID';
//Extract results from Data Extension using DE key
var results = DataExtension.Init(ZB_DataExtension).Rows.Retrieve();
var updateDE_ZB = DataExtension.Init(ZB_DataExtension_Response);
var logsDE_ZB = DataExtension.Init(ZB_DataExtension_Logs);
var today = Format(Now(), "YYYY-MM-DD ");
for (var i = 0; i < results.length; i++ ) {
var item = results[i];
var zeroBounceUrlItem = "";
var ZB_Status = "";
var currentDateTime = Now();
try{
setTimeout(() => (
zeroBounceUrlItem = String(zeroBounceFullUrl).split("CUST_ID").join(String(item.C7_CustID));
var req = new Script.Util.HttpRequest(zeroBounceUrlItem);
req.emptyContentHandling = 0;
req.retries = 3;
req.continueOnError = true;
req.contentType = "application/json";
req.method = "PUT";
var payload='{"emailMarketingStatus": "Unsubscribed"}'
req.postData = payload ;
var resp = req.send();
var returnStatus= resp.returnStatus;
updateDE_ZB.Rows.Update({C7_API_Answer:String(returnStatus),ValidationDate:currentDateTime,ValidationUrl:String(zeroBounceUrlItem),EmailAddress:String(item.EmailAddress)}, ["C7_CustID"], [String(item.C7_CustID)]);
if (returnStatus==0) {
updateDE_ZB.Rows.Update({C7_API_Answer:String("Success"),ValidationDate:currentDateTime,ValidationUrl:String(zeroBounceUrlItem),EmailAddress:String(item.EmailAddress)}, ["C7_CustID"], [String(item.C7_CustID)]);
}
else {
//ZB_Status = String("ERRO ZB API Call");
//var responseJson = Platform.Function.ParseJSON(String(resp.content));
updateDE_ZB.Rows.Update({C7_API_Answer:String("Failure"),ValidationDate:currentDateTime,ValidationUrl:String(zeroBounceUrlItem),EmailAddress:String(item.EmailAddress)}, ["C7_CustID"], [String(item.C7_CustID)]);
}
var randomID = Platform.Function.GUID();
logsDE_ZB.Rows.Add({log_guid:String(randomID),C7_CustID:String(item.C7_CustID),Status:String("Success"),ValidationDate:currentDateTime,ValidationUrl:String(zeroBounceUrlItem)});
), 1000*i}
catch (err) {
var randomID = Platform.Function.GUID();
ZB_Status = String("ERRO AMPScript");
logsDE_ZB.Rows.Add({log_guid:String(randomID),C7_CustID:String(item.C7_CustID),Status:String("Failure"),ValidationDate:currentDateTime,ValidationUrl:String(zeroBounceUrlItem)});
}
}
</script>
Your loop will execute the right number of times and at the right interval, but the value of the variable item inside the timeout might not be what you expect.
Try this:
for (var i = 0; i < results.length; i++ ) {
(function(i){
setTimeout(function(){
var item = results[i];
var zeroBounceUrlItem = "";
var ZB_Status = "";
var currentDateTime = Now();
try{
zeroBounceUrlItem = String(zeroBounceFullUrl).split("CUST_ID").join(String(item.C7_CustID));
var req = new Script.Util.HttpRequest(zeroBounceUrlItem);
req.emptyContentHandling = 0;
req.retries = 3;
req.continueOnError = true;
req.contentType = "application/json";
req.method = "PUT";
var payload='{"emailMarketingStatus": "Unsubscribed"}'
req.postData = payload ;
var resp = req.send();
var returnStatus= resp.returnStatus;
updateDE_ZB.Rows.Update({C7_API_Answer:String(returnStatus),ValidationDate:currentDateTime,ValidationUrl:String(zeroBounceUrlItem),EmailAddress:String(item.EmailAddress)}, ["C7_CustID"], [String(item.C7_CustID)]);
if (returnStatus==0) {
updateDE_ZB.Rows.Update({C7_API_Answer:String("Success"),ValidationDate:currentDateTime,ValidationUrl:String(zeroBounceUrlItem),EmailAddress:String(item.EmailAddress)}, ["C7_CustID"], [String(item.C7_CustID)]);
}
else {
//ZB_Status = String("ERRO ZB API Call");
//var responseJson = Platform.Function.ParseJSON(String(resp.content));
updateDE_ZB.Rows.Update({C7_API_Answer:String("Failure"),ValidationDate:currentDateTime,ValidationUrl:String(zeroBounceUrlItem),EmailAddress:String(item.EmailAddress)}, ["C7_CustID"], [String(item.C7_CustID)]);
}
var randomID = Platform.Function.GUID();
logsDE_ZB.Rows.Add({log_guid:String(randomID),C7_CustID:String(item.C7_CustID),Status:String("Success"),ValidationDate:currentDateTime,ValidationUrl:String(zeroBounceUrlItem)});
catch (err) {
var randomID = Platform.Function.GUID();
ZB_Status = String("ERRO AMPScript");
logsDE_ZB.Rows.Add({log_guid:String(randomID),C7_CustID:String(item.C7_CustID),Status:String("Failure"),ValidationDate:currentDateTime,ValidationUrl:String(zeroBounceUrlItem)});
}
}, i*1000);
})(i);

I am trying this code, but can't get it to work, it says "The name "text" does not exist in the current context"
CurBrowser.GetMainFrame().ExecuteJavaScriptAsync("for(var i = 0; i < elems1.length; i++){ var textt = elems1[i].innerText}");
string docPath = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
using (StreamWriter outputFile = new StreamWriter(Path.Combine(docPath, "WriteLines.txt"), true))
{
outputFile.WriteLine(textt);
}
How can I make variable "textt" accessible?
Here is a full code:
private void button3_Click(object sender, EventArgs e)
{
CurBrowser.GetMainFrame().ExecuteJavaScriptAsync("var elems1 = document.getElementsByClassName('question-text')");
CurBrowser.GetMainFrame().ExecuteJavaScriptAsync("for(var i = 0; i < elems1.length; i++){var textt = elems1[i].innerText}");
string docPath = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
using (StreamWriter outputFile = new StreamWriter(Path.Combine(docPath, "WriteLines.txt"), true))
{
outputFile.WriteLine(textt);
}
}
You might be looking for ContinueWith() which can be chained after ExecuteJavaScriptAsync().
In this example you need to use your JavaScript code as a function which returns anything (ex. textt). So I've created something like this:
var myScript = #"(function () {
var textt = "";
var elems1 = document.getElementsByClassName('question-text');
for(var i = 0; i < elems1.length; i++){
textt += elems1[i].innerText
}
return textt;
})();";
than I asynchronously evaluate it and catch the result which I am returning from that function:
var result = await CurBrowser
.GetMainFrame()
.EvaluateScriptAsync(myScript)
.ContinueWith(t => {
var result = t.Result; // your textt
string docPath = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
using (StreamWriter outputFile = new StreamWriter(Path.Combine(docPath, "WriteLines.txt"), true)) {
outputFile.WriteLine(result);
}
});
this is just a suggestion of how it might work.
Can anyone assist me with loading an array with excel data and returning it as a function? This is my initial code:
var excel = require('exceljs');
var wb = new excel.Workbook();
var path = require('path');
var filePath = path.resolve(__dirname,'data.xlsx');
function signIn(){
var SignIn = [];
wb.xlsx.readFile(filePath).then(function(){
var sh = wb.getWorksheet("Sheet1");
for(var i = 1; i < 3; i++){
SignIn.push(sh.getRow(i).getCell(2).value);
}
});
return SignIn
}
Workbook.readFile is aynchronous, you need to use either a callback or promise type approach. Using promises we can try:
var excel = require('exceljs');
var wb = new excel.Workbook();
var path = require('path');
var filePath = path.resolve(__dirname,'data.xlsx');
function signIn() {
var SignIn = [];
return wb.xlsx.readFile(filePath).then( () => {
var sh = wb.getWorksheet("Sheet1");
for(var i = 1; i < 3; i++){
SignIn.push(sh.getRow(i).getCell(2).value);
}
return SignIn;
});
}
async function testReadData() {
try {
let data = await signIn();
console.log('testReadData: Loaded data: ', data);
} catch (error) {
console.error('testReadData: Error occurred: ', error);
}
}
testReadData();
Or you can use a callback type approach:
function signInWithCallback(callback) {
var SignIn = [];
wb.xlsx.readFile(filePath).then(function(){
var sh = wb.getWorksheet("Sheet1");
for(var i = 1; i < 3; i++){
SignIn.push(sh.getRow(i).getCell(2).value);
}
callback(SignIn);
});
}
signInWithCallback((data) => console.log('Callback: Data: ', data));
I'm trying to make an extension that collecting social networks links from the web page where user is. So when user clicking button getLinks we get all links and then by checking condition passing them in the blocks of the extension. I tried to use chrome.tabs.executeScript, and get links through urls = $$('a'); but it's not working
$('#getLinks').click(function(e)
{
var allLinks = [];
var i = 0;
chrome.tabs.executeScript( null, {"code": "urls = $$('a'); for (url in urls)
{ allLinks[i]=urls[url].href; i++;}"}, function() {
var vk;
var facebook;
var linkedin;
for (var i=0; i<allLinks.length; i++)
{
var profil = (allLinks[i].href);
if(profil.indexOf('vk.com')!=-1)
{
vk = profil;
$('#vk').text(vk);
}
if(profilito.indexOf('facebook.com')!=-1)
{
facebook = profil;
$('#fb').text(facebook);
}
if(profilito.indexOf('linkedin.com')!=-1)
{
linkedin = profil;
$('#linkin').text(linkedin);
}
}
});
});
That's not how executeScript is used. That code can not access the variables allLinks and i because it is executed elsewhere. But you can make use of the returned value of that code like in this other SO question:
$('#getLinks').click(function(e) {
chrome.tabs.executeScript( null, {"code": "var urls = document.querySelectorAll('a'); for(var i = 0; i < urls.length; i++) { urls[i] = urls[i].href; }; urls"}, function(results) {
var allLinks = results[0];
// use allLinks here
});
});
So finally I got an answer on my own question and posting here the solution
$('#getUser').click(function(e) {
chrome.tabs.executeScript(null,{code: 'Array.from(document.getElementsByTagName("a")).map(a => a.innerHTML)'},function (results){
var vk = [];
var facebook = [];
var linkedin = [];
var allElements = results[0];
for (var i=0; i<allElements.length; i++)
{
if (allElements[i].indexOf("https://vk.com") !== -1)
{
vk.push (allElements[i]);
}
if (allElements[i].indexOf("https://facebook.com") !== -1 )
{
facebook.push (allElements[i]);
}
if (allElements[i].indexOf("https://www.linkedin.com") !== -1 )
{
linkedin.push (allElements[i]);
}
}
});
All links that we are finding on the page sorted in 3 arrays by belonging to the social networks
After asking a question and getting a very helpful answer on what the 'Async Juggling' assignment in learnyounode was asking me to do, I set out to implement it myself.
The problem is, my setup isn't having any success! Even though I've referred to other solutions out there, my setup simply isn't returning any results when I do a learnyounode verify myscript.js.
GIST: jugglingAsync.js
var http = require('http');
var app = (function () {
// Private variables...
var responsesRemaining,
urls = [],
responses = [];
var displayResponses = function() {
for(var iterator in responses) {
console.log(responses[iterator]);
}
};
// Public scope...
var pub = {};
pub.main = function (args) {
responsesRemaining = args.length - 2;
// For every argument, push a URL and prep a response.
for(var i = 2; i < args.length; i++) {
urls.push(args[i]);
responses.push('');
}
// For every URL, set off an async request.
for(var iterator in urls) {
var i = iterator;
var url = urls[i];
http.get(url, function(response) {
response.setEncoding('utf8');
response.on('data', function(data) {
if(response.headers.host == url)
responses[i] += data;
});
response.on('end', function() {
if(--responsesRemaining == 0)
displayResponses();
});
});
}
};
return pub;
})();
app.main(process.argv);
Question: What am I doing wrong?
This line
for(var iterator in urls) {
doesn't do what you think it does. It actually loops over the properties of urls (see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...in). Instead, you have to do something like
for(var i = 0; i < urls.length; i++) {
var url = urls[i];
...
}
or
urls.forEach(function(url, index) {
...
});
In addition to not properly looping through the arrays inside the app module, I was also not properly concatenating data returned from the response.on('data') event. Originally I was doing...
responses[index] += data;
Instead, the correct thing to do was:
responses[index] = responses[index] + data;
Changing that, as well as the things noted by #arghbleargh got the 'Async Juggling' to fully verify!
I have tested my code and it all worked:
~ $ node juggling_async.js site1 site2 site3 site4 ...
The JS code does not limit only to three sites.
var http = require('http');
// Process all the site-names from the arguments and store them in sites[].
// This way does not limit the count to only 3 sites.
var sites = [];
(function loadSites() {
for(var i = 2, len = process.argv.length; i < len; ++i) {
var site = process.argv[i];
if(site.substr(0, 6) != 'http://') site = 'http://' + site;
sites.push(site);
}
})();
var home_pages = [];
var count = 0;
function httpGet(index) {
var home_page = '';
var site = sites[index];
http.get(site, function(res) {
res.setEncoding('utf8');
res.on('data', function(data) {
home_page += data;
});
res.on('end', function() {
++count;
home_pages[index] = home_page;
if(count == sites.length) {
// Yahoo! We have reached the last one.
for(var i = 0; i < sites.length; ++i) {
console.log('\n############ Site #' + (+i+1) + ': ' + sites[i]);
console.log(home_pages[i]);
console.log('============================================\n');
}
}
});
})
.on('error', function(e) {
console.log('Error at loop index ' + inddex + ': ' + e.message);
})
;
}
for(var i = 0; i < sites.length; ++i) {
httpGet(i);
}
