I am trying to create a for loop using Google Script and having a hard time with adding records. When I add a record, I receive one's email and then 36 questions as such:
function AddRecord(email, q1, q2, q3, q4, q5, q6, q7, q8, q9, q10, q11, q12, q13, q14, q15, q16, q17, q18, q19, q20, q21, q22, q23, q24, q25, q26, q27, q28, q29, q30, q31, q32, q33, q34, q35, q36){
var url ="Name of Url";
var ss= SpreadsheetApp.openByUrl(url);
var ws = ss.getSheetByName("Sheet1");
ws.appendRow([email, q1, q2, q3, q4, q5, q6, q7, q8, q9, q10, q11, q12, q13, q14, q15, q16, q17, q18, q19, q20, q21, q22, q23, q24, q25, q26, q27, q28, q29, q30, q31, q32, q33, q34, q35, q36]);}
I would think the code below would allow me to pass this function correctly by the spread operator. I have tried different things but I am confused with how to proceed dealing with parameters/arrays/etc. How would I go about creating a for loop for this?
const questions = [];
for (let i = 1; i <= 36; i++) {
questions.push(`q${i}`);
}
function AddRecord(email, ... questions){
var url ="Name of Url";
var ss= SpreadsheetApp.openByUrl(url);
var ws = ss.getSheetByName("Sheet1");
ws.appendRow([email, ... questions]);}
Try this:
function AddRecord(email, questions) {
var url = "Name of Url";
var ss = SpreadsheetApp.openByUrl(url);
var ws = ss.getSheetByName("Sheet1");
questions.unshift(email)
ws.appendRow(questions);
}
I had to do this to test it.
function AddRecord() {
const email = 'email';
const questions = [];
for (let i = 1; i <= 36; i++) { questions.push(`q${i}`); }
var id = gobj.globals.testsourceid;//I have this id in globals
var ss = SpreadsheetApp.openById(id);//so I went with openById()
var ws = ss.getSheetByName("Sheet2");
questions.unshift(email)
ws.appendRow(questions);
}
Testing it this way is much better:
function testAddRecord() {
const email = 'email';
const questions = [];
for (let i = 1; i <= 36; i++) { questions.push(`q${i}`); }
AddRecord(email, questions);
}
function AddRecord(email, questions) {
var id = gobj.globals.testsourceid;
var ss = SpreadsheetApp.openById(id);
var ws = ss.getSheetByName("Sheet2");
questions.unshift(email)
ws.appendRow(questions);
}
output:

jslint tell Unexpected 'for'.
so i think that i must convert for with foreach
but how?
if someone can help
thanks
// Grab the original element
var original = document.getElementsByTagName("noscript")[0];
// Create a replacement tag of the desired type
var replacement = document.createElement("span");
var i;
// Grab all of the original's attributes, and pass them to the replacement
for(i = 0, l = original.attributes.length; i < l; ++i){
var nodeName = original.attributes.item(i).nodeName;
var nodeValue = original.attributes.item(i).nodeValue;
replacement.setAttribute(nodeName, nodeValue);
}
// Persist contents
replacement.innerHTML = original.innerHTML;
// Switch!
original.parentNode.replaceChild(replacement, original);
You have a comma after i = 0, <========
it should be semicolon.
Another issue is declaring l = original.attributes.length you don't need the variable l
just use it as for(i = 0; i < original.attributes.length; ++i){
if you still wanna use a forEach you can do it as:
original.attributes.forEach(element => {
var nodeName = element.nodeName;
var nodeValue = element.nodeValue;
replacement.setAttribute(nodeName, nodeValue);
});
thanks for your answer, i got Uncaught TypeError: original.attributes.forEach is not a function
function Switch() {
var original = document.getElementsByTagName("noscript")[0];
var replacement = document.createElement("span");
original.attributes.forEach(element => {
var nodeName = element.nodeName;
var nodeValue = element.nodeValue;
replacement.setAttribute(nodeName, nodeValue);
});
// Persist contents
replacement.innerHTML = original.innerHTML;
// Switch!
original.parentNode.replaceChild(replacement, original);

Is there a way to optimize my code so I can get a better response time and especially avoid the Connection timed out after 10000 milliseconds exception?
I'm assuming to get the API data and parse it... it is taking longer than 10 seconds?
You have 2 things to do to improve your system: 1) Use Cache 2) Use Queues.
Cache! (Save the API/parsed result for 15 minutes or so)
Queues! (API parsing is done in the server background)
Your system workflow will be:
User hits /stats
Is there a cache version? Use it. Response time ~ barely 500ms.
No/Expired cache? Fire a Queued Job to get the new API data.
Show the user 'Data is being refreshed!' and display the latest cache.
i'm trying to implement play and pause button using Rxjs library.
const play$ = fromEvent(playerImplementation, PLAYER_EVENTS.PLAY).pipe(mapTo(true));
const pause$ = fromEvent(playerImplementation, PLAYER_EVENTS.PAUSE).pipe(mapTo(false));
const waiting$ = fromEvent(playerImplementation, PLAYER_EVENTS.WAITING).pipe(mapTo(false));
let counterTime = 0;
const currentTime$ = interval(30).pipe(
map(()=>counterTime += 30));
const player$ = merge(play$, pause$, waiting$).pipe(
switchMap(value => (value ? currentTime$ : EMPTY)));
// DIFFERENCE IN RESULTS
currentTime$.subscribe((v)=> console.log("Regular Count " + v)); // get correctly 30,60,90,120...
player$.subscribe((v)=>console.log("Condition Count" + v)); // get wrongly 30,150,270, 390
can anyone help in understanding why there is a difference between the results?
It happened because I used several subscribers for one observable (player$ observable). I solve this by using ReplaySubject instead of Observable and by using multicasting in order to handle the event in several subscribers, without changing the value.
const play$ = fromEvent(playerImplementation, PLAYER_EVENTS.PLAY).pipe(mapTo(true));
const pause$ = fromEvent(playerImplementation, PLAYER_EVENTS.PAUSE).pipe(mapTo(false));
const waiting$ = fromEvent(playerImplementation, PLAYER_EVENTS.WAITING).pipe(mapTo(false));
let timeCounter = 0;
const source = Observable.create((obs : Observer<number>)=> {
interval(30).pipe(
map(() => timeCounter += 30)).subscribe(obs);
return () => {};
});
// Cast the observable to subject for distributing to several subscribers
const currentTime$ = source.pipe(multicast(()=> new ReplaySubject(5))).refCount();
const player$ = merge(play$, pause$, waiting$).pipe(
switchMap(value => value ? currentTime$ : EMPTY));

Would appreciate your help. Thanks
Firstly, your query would only find exact objects of type Pushpin. This is cleaner:
var pushpin = map1.Children.OfType<Pushpin>()
.FirstOrDefault(p => p.Tag == "locationPushpin");
The next problem is that Tag is of type object. So you really want:
var pushpin = map1.Children.OfType<Pushpin>()
.FirstOrDefault(p => "locationPushpin".Equals(p.Tag));
Otherwise you'll be doing a reference comparison between the Tag value and the string. So you could have equal but distinct strings, and the pushpin wouldn't be found.
