Develop Reference

I need to allocate a url to very student name in Javascript

The name list is supposedly as below:
Rose : 35621548
Jack : 32658495
Lita : 63259547
Seth : 27956431
Cathy: 75821456
Given you have a variable as StudentCode that contains the list above (I think const will do! Like:
const StudentCode = {
[Jack]: [32658495],
[Rose]: [35621548],
[Lita]: [63259547],
[Seth]: [27956431],
[Cathy]:[75821456],
};
)
So here are the questions:
1st: Ho can I define them in URL below:
https://www.mylist.com/student=?StudentCode
So the link for example for Jack will be:
https://www.mylist.com/student=?32658495
The URL is imaginary. Don't click on it please.
2nd: By the way the overall list is above 800 people and I'm planning to save an external .js file to be called within the current code. So tell me about that too. Thanks a million

Given
const StudentCode = {
"Jack": "32658495",
"Rose": "35621548",
"Lita": "63259547",
"Seth": "27956431",
"Cathy": "75821456",
};
You can construct urls like:
const urls = Object.values(StudentCode).map((c) => `https://www.mylist.com?student=${c}`)
// urls: ['https://www.mylist.com?student=32658495', 'https://www.mylist.com?student=35621548', 'https://www.mylist.com?student=63259547', 'https://www.mylist.com?student=27956431', 'https://www.mylist.com?student=75821456']
To get the url for a specific student simply do:
const url = `https://www.mylist.com?student=${StudentCode["Jack"]}`
// url: 'https://www.mylist.com?student=32658495'
Not sure I understand your second question - 800 is a rather low number so will not be any performance issues with it if that is what you are asking?

The properties of the object (after the trailing comma is removed) can be looped through using a for-in loop, (see: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...in)
This gives references to each key of the array and the value held in that key can be referenced using objectName[key], Thus you will loop through your object using something like:
for (key in StudentCode) {
keyString = key; // e.g = "Jack"
keyValue = StudentCode[key]; // e.g. = 32658495
// build the urls and links
}
to build the urls, string template literals will simplify the process (see: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals) allowing you to substitute values in your string. e.g.:
url = `https://www.mylist.com/student=?${StudentCode[key]`}
Note the use of back ticks and ${} for the substitutions.
Lastly, to build active links, create an element and sets its innerHTML property to markup built using further string template literals:
let link = `<a href=${url}>${keyValue}</a>`
These steps are combined in the working snippet here:
const StudentCode = {
Jack: 32658495,
Rose: 35621548,
Lita: 63259547,
Seth: 27956431,
Cathy: 75821456,
};
const studentLinks = [];
for (key in StudentCode) {
let url = `https://www.mylist.com/student=?${StudentCode[key]}`;
console.log(url);
studentLinks.push(`<a href href="url">${key}</a>`)
}
let output= document.createElement('div');
output.innerHTML = studentLinks.join("<br>");
document.body.appendChild(output);

Cheerio Not Parsing HTML Correctly

I've got an array of rows that I've parsed out of a table from html, stored in a list. Each of the rows in the list is a string that looks (something) like this:
["<td headers="DOCUMENT" class="t14data"><a target="6690-Exhibit-C-20190611-1" href="http://www.fara.gov/docs/6690-Exhibit-C-20190611-1.pdf" class="doj-analytics-processed"><span style="color:blue">Click Here </span></a></td><td headers="REGISTRATIONNUMBER" class="t14data">6690</td><td headers="REGISTRANTNAME" class="t14data">SKDKnickerbocker LLC</td><td headers="DOCUMENTTYPE" class="t14data">Exhibit C</td><td headers="STAMPED/RECEIVEDDATE" class="t14data">06/11/2019</td>","<td headers="DOCUMENT" class="t14data"><a target="5334-Supplemental-Statement-20190611-30" href="http://www.fara.gov/docs/5334-Supplemental-Statement-20190611-30.pdf" class="doj-analytics-processed"><span style="color:blue">Click Here </span></a></td><td headers="REGISTRATIONNUMBER" class="t14data">5334</td><td headers="REGISTRANTNAME" class="t14data">Commonwealth of Dominica Maritime Registry, Inc.</td><td headers="DOCUMENTTYPE" class="t14data">Supplemental Statement</td><td headers="STAMPED/RECEIVEDDATE" class="t14data">06/11/2019</td>"]
The code is pulled from the page with the following page.evaluate function using puppeteer.
I'd like to then parse this code with cheerio, which I find to be simpler and more understandable. However, when I pass each of the strings of html into cheerio, it fails to parse them correctly. Here's the current function I'm using:
let data = res.map((tr) => {
let $ = cheerio.load(tr);
const link = $("a").attr("href");
const number = $("td[headers='REGISTRATIONNUMBER']").text();
const name = $("td[headers='REGISTRANTNAME']").text();
const type = $("td[headers='DOCUMENTTYPE']").text();
const date = $("td[headers='STAMPED/RECEIVEDDATE']").text();
return { link, number, name, type, date };
});
For some reason, only the "a" tag is working correctly for each row. Meaning, the "link" variable is correctly defined, but none of the other ones are. When I use $("*") to return a list of what should be all of the td's, it returns an unusual node list:
What am I doing wrong, and how can I gain access to the td's with the various headers, and their text content? Thanks!

It usually looks more like this:
let data = res.map((i, tr) => {
const link = $(tr).find("a").attr("href");
const number = $(tr).find("td[headers='REGISTRATIONNUMBER']").text();
const name = $(tr).find("td[headers='REGISTRANTNAME']").text();
const type = $(tr).find("td[headers='DOCUMENTTYPE']").text();
const date = $(tr).find("td[headers='STAMPED/RECEIVEDDATE']").text();
return { link, number, name, type, date };
}).get();
Keep in mind that cheerio map has the arguments reversed from js map.

I found the solution. I'm simply returning the full html through puppeteer instead of trying to get individual rows, and then using the above suggestion (from #pguardiario) to parse the text:
const res = await page.evaluate(() => {
return document.body.innerHTML;
});
let $ = cheerio.load(res);
let trs = $(".t14Standard tbody tr.highlight-row");
let data = trs.map((i, tr) => {
const link = $(tr).find("a").attr("href");
const number = $(tr).find("td[headers='REGISTRATIONNUMBER']").text();
const registrant = $(tr).find("td[headers='REGISTRANTNAME']").text();
const type = $(tr).find("td[headers='DOCUMENTTYPE']").text();
const date = moment($(tr).find("td[headers='STAMPED/RECEIVEDDATE']").text()).valueOf().toString();
return { link, number, registrant, type, date };
});

how can i convert my data in javascript server side to json object and array?

i'm working with xpages and javascript server side i want to convert the fields in format json then i parse this dat and i put them in a grid,the problem is that these fields can contains values :one item or a list how can i convert them in json ?
this is my code :
this.getWFLog = function ()
{
var wfLoglines = [];
var line = "";
if (this.doc.hasItem (WF.LogActivityPS) == false) then
return ("");
var WFLogActivityPS = this.doc.getItem ("WF.LogActivityPS");
var WFActivityInPS = this.doc.getItem ("WFActivityInPS");
var WFActivityOutPS = this.doc.getItem ("WFActivityOutPS");
var WFLogDecisionPS = this.doc.getItem ("WF.LogDecisionPS");
var WFLogSubmitterPS = this.doc.getItem ("WF.LogSubmitterPS");
var WFLogCommentPS = this.doc.getItem ("WF.LogCommentPS");
var WFLogActivityDescPS = this.doc.getItem ("WF.LogActivityDescPS");
var Durr =((WFActivityOutPS-WFActivityInPS)/3600);
var json= {
"unid":"aa",
"Act":WFLogActivityPS,
"Fin":WFActivityOutPS,
"Durr":Durr,
"Decision":WFLogDecisionPS,
"Interv":WFLogSubmitterPS,
"Instruction":WFLogActivityDescPS,
"Comment":WFLogCommentPS
}
/*
*
* var wfdoc = new PSWorkflowDoc (document1, this);
histopry = wfdoc.getWFLog();
var getContact = JSON.parse(histopry );
*/ }

Careful. Your code is bleeding memory. Each Notes object you create (like the items) needs to be recycled after use calling .recycle().
There are a few ways you can go about it. The most radical would be to deploy the OpenNTF Domino API (ODA) which provides a handy document.toJson() function.
Less radical: create a helper bean and put code inside there. I would call a method with the document and an array of field names as parameter. This will allow you to loop through it.
Use the Json helper methods found in com.ibm.commons.util.io.json they will make sure all escaping is done properly. You need to decide if you really want arrays and objects mixed - especially if the same field can be one or the other in different documents. If you want them flat use item.getText(); otherwise use item.getValues() There's a good article by Jesse explaining more on JSON in XPages. Go check it out. Hope that helps.

If an input field contains several values that you want to transform into an array, use the split method :
var WFLogActivityPS = this.doc.getItem("WF.LogActivityPS").split(",")
// input : A,B,C --> result :["A","B","C"]

How can I use underscore in name of dynamic object variable

Website that I'm making is in two different languages each data is saved in mongodb with prefix _nl or _en
With a url I need to be able to set up language like that:
http://localhost/en/This-Is-English-Head/This-Is-English-Sub
My code look like that:
var headPage = req.params.headPage;
var subPage = req.params.subPage;
var slug = 'name';
var slugSub = 'subPages.slug_en';
var myObject = {};
myObject[slugSub] = subPage;
myObject[slug] = headPage;
console.log(myObject);
Site.find(myObject,
function (err, pages) {
var Pages = {};
pages.forEach(function (page) {
Pages[page._id] = page;
});
console.log(Pages);
});
After console.log it I get following:
{ 'subPages.slug_en': 'This-Is-English-Sub',
name: 'This-Is-English-Head' }
Is you can see objectname subPages.slug_en is seen as a String insteed of object name..
I know that javascript does not support underscores(I guess?) but I'm still looking for a fix, otherwise i'll be forced to change all underscores in my db to different character...
Edit:
The final result of console.log need to be:
{ subPages.slug_en: 'This-Is-English-Sub',
name: 'This-Is-English-Head' }
Insteed of :
{ 'subPages.slug_en': 'This-Is-English-Sub',
name: 'This-Is-English-Head' }
Otherwise it does not work

The reason you are seeing 'subPages.slug_en' (with string quotes) is because of the . in the object key, not the underscore.
Underscores are definitely supported in object keys without quoting.
Using subPages.slug_en (without string quotes) would require you to have an object as follows:
{ subPages: {slug_en: 'This-Is-English-Sub'},
name: 'This-Is-English-Head' }
Which you could set with the following:
myObject['subPages']['slug_en'] = subPage;
Or simply:
myObject.subPages.slug_en = subPage;

Ways to pass values into Javascript options objects using ASP

Options objects (so called) are used to collect static parameters from the page for a javascript file to operate on. What are the best ways to pass dynamic values from the page into a javascript options object?
Eg how should you insert a value for MyAlbumID in the following
MyOptionsObject({
flashvars: {
xmlFilePath: "http://myurl.com/images.php?album=" + MyAlbumID
})​
Where MyAlbumID is obtained from:
var albumspan = document.getElementById("lblMyAlbum");
var albumtextnode = albumspan.firstChild;
var MyAlbumID = albumtextnode.data;

What exactly is the problem?
onDynamicAction(function(){
// ensure that the DOM is loaded when that action happens
var myAlbumID = document.getElementById("lblMyAlbum").firstChild.data;
// lets hope there is an element with that id and a textnode,
// so that this threw no error
MyOptionsObject ({
flashvars: {
xmlFilePath: "http://myurl.com/images.php?album=" + myAlbumID
} // missing bracket, btw.
});
// set a new object
})
