Return string from UnityWebGL jslib - javascript

I want use jslib to get url parameter
code like this
jslib
GetUrl: function(){
var s ="";
var strUrl = window.location.search;
var getSearch = strUrl.split("?");
var getPara = getSearch[1].split("&");
var v1 = getPara[0].split("=");
alert(v1[1]);
return v1[1];
},
});
c#
[DllImport("__Internal")]
public static extern string GetUrl();
void Start () {
TextShow.text = GetUrl();
}
When run alert from jslib , I see right string show in alert but UGUI Text shows nothing.
Why did this happen?

To return string from Javascript to Unity, you must use _malloc to allocate memory then writeStringToMemory to copy the string data from your v1[1] variable into the newly allocated memory then return that.
GetUrl: function()
{
var s ="";
var strUrl = window.location.search;
var getSearch = strUrl.split("?");
var getPara = getSearch[1].split("&");
var v1 = getPara[0].split("=");
alert(v1[1]);
//Allocate memory space
var buffer = _malloc(lengthBytesUTF8(v1[1]) + 1);
//Copy old data to the new one then return it
writeStringToMemory(v1[1], buffer);
return buffer;
}
The writeStringToMemory function seems to be deprecated now but you can still do the-same thing with stringToUTF8 and proving the size of the string in its third argument.
GetUrl: function()
{
var s ="";
var strUrl = window.location.search;
var getSearch = strUrl.split("?");
var getPara = getSearch[1].split("&");
var v1 = getPara[0].split("=");
alert(v1[1]);
//Get size of the string
var bufferSize = lengthBytesUTF8(v1[1]) + 1;
//Allocate memory space
var buffer = _malloc(bufferSize);
//Copy old data to the new one then return it
stringToUTF8(v1[1], buffer, bufferSize);
return buffer;
}

How to set a time-driven (clock) trigger for a function that needs parameters sent to it?

I'm trying to have a function run with a time-driven (clock) trigger. My issue is, the function needs variables sent to it as parameters. Normally if I'm not using a trigger I'll just send it directly like this.
<script>
function runFunction(){
google.script.run.myFunction(x,y,z);
}
</script>
And on the server side, I'll call them easily.
function myFunction(x,y,z){
var a = x;
var b = y;
var c = z;
Logger.log(a+b+c);
}
But when I'm using a time-driven (clock) trigger to run the function how can I get x,y,z into the function.
I searched around and saw one method of creating scriptProperties out of the parameters in the trigger function like this.
EDITED This is the actual code.
Client side.
<script>
function sendCall() {
var testNumber = document.getElementById('numberCall').value;
var testGroup = document.getElementById('groupsCall').value;
var testtime = document.getElementById('scheduleCall').value;
var now = document.getElementsByName('sendTimeCall')[0].checked;
var number;
if(testNumber == ''){
number = null;
}else{
number = testNumber;
}
var group;
if(testGroup == ""){
group = null;
}else{
group = testGroup;
}
var time;
if(testtime == ''){
time = null;
}else{
time = testtime;
}
var file = document.getElementsByName('audio')[0].files[0];
var name = file.name;
var reader = new FileReader();
reader.onload = function (e) {
var content = reader.result;
google.script.run.withSuccessHandler(success2).triggerCall(group, number, content, time, now, name);
return false;
}
reader.readAsDataURL(file);
}
</script>
Server side - Trigger Function.
function triggerCall(group, number, content, time, now, name){
var scriptProperties = PropertiesService.getScriptProperties();
scriptProperties.setProperties({
'GROUP_CALL': group,
'AUDIO': content,
'NUMBER_CALL': number,
'FILE_NAME': name
});
var status;
if(now){
status = 'Call Sent';
}else{
status = 'Call Scheduled';
}
if(now){
return makeCall(status);
}else{
// Set here the date you want to schedule the one-time trigger
var rawdate = time;
var today_D = new Date(new Date().toLocaleString("en-US", {timeZone: "America/New_York"}));
var scheduled_D = new Date(rawdate);
var time_af = Math.abs(scheduled_D - today_D) / 36e5;
ScriptApp.newTrigger("makeCall")
.timeBased()
.after(time_af * 60 *60 * 1000)
.create();
}
return status;
}
Server side - Here is The function that actually does the work.
function makeCall(status) {
var scriptProperties = PropertiesService.getScriptProperties();
var blob = scriptProperties.getProperty('AUDIO');
var number = scriptProperties.getProperty('NUMBER_CALL');
var group = scriptProperties.getProperty('GROUP_CALL');
var name = scriptProperties.getProperty('FILE_NAME');
var fullNumber;
if(group){
var ss = SpreadsheetApp.openById('xxxxxxxxxxxxxxxxxxx');
var sheet = ss.getSheetByName(group)
var length = sheet.getLastRow();
var values = sheet.getRange(1, 1, length).getValues();
fullNumber = values.flat();
}else{
var num = number;
var prefix = '+1';
var removeDashes = num.replace(/-/g,"");
var format = prefix + removeDashes;
var comma = format.replace(/ /g, ' +1');
fullNumber = comma.split(' ')
}
//upload file to drive
var folder = DriveApp.getFolderById('xxxxxxxxxxxxxxxxxxxxxx');
var blob = blob.split(",");
var blob = Utilities.newBlob(Utilities.base64Decode(blob[1]), 'audio/mpeg', name);
var file = folder.createFile(blob);
file.setSharing(DriveApp.Access.ANYONE_WITH_LINK, DriveApp.Permission.VIEW);
var id = file.getId();
for (var i = 0; i < fullNumber.length; i++){
//the url with HTTP request to create a call and parameters
var callsUrl = "https://api.twilio.com/2010-04-01/Accounts/ACxxxxxxxxxxxxxxxx/Calls.json";
var payload = {
"To": fullNumber[i],
"From" : "+177777777",
"Twiml" : "<Response><Play>https://docs.google.com/uc?export=play&id=" + id + "</Play></Response>",
};
var options = {
"method" : "post",
"payload" : payload
};
options.headers = {
"Authorization" : "Basic " + Utilities.base64Encode("xxxxxxxxxxx:xxxxxxxx")
};
UrlFetchApp.fetch(callsUrl, options);
}
scriptProperties.deleteProperty('AUDIO');
scriptProperties.deleteProperty('NUMBER_CALL');
scriptProperties.deleteProperty('GROUP_CALL');
scriptProperties.deleteProperty('FILE_NAME');
return status;
}
The problem is when I run the above code without the file input it works, But when I run it as above the function doesn't work. I did some trouble shooting and I think it has to do with transferring the file as a Data URL via the properties method. Is there a limit to how long of a string the VALUE can be?
in a nut shell these are the 2 points of my question.
Any other ideas how to send parameters to a triggered function
How I could do it using PropertiesService.
I would like to propose the following modification.
Modification points:
I think that the reason of your issue might be due to the maximum data size for PropertiesService. In the current stage, it seems that "Properties total storage" is "500kB / property store". I thought that in this case, when you upload a file, the file size might be over than it.
In order to remove your issue, how about creating content as a temporal file and put the file ID to the PropertiesService?
When above points are reflected to your script, it becomes as follows.
Pattern 1:
In this pattern, content is saved as a temporal file and that is used in the function of makeCall().
triggerCall()
function triggerCall(group, number, content, time, now, name){
var scriptProperties = PropertiesService.getScriptProperties();
var tempFile = DriveApp.createFile("tempFile.txt", content, MimeType.PLAIN_TEXT); // Added
scriptProperties.setProperties({'GROUP_CALL': group,'AUDIO': tempFile.getId(),'NUMBER_CALL': number,'FILE_NAME': name}); // Modified
var status;
if(now){
status = 'Call Sent';
}else{
status = 'Call Scheduled';
}
if(now){
return makeCall(status);
}else{
var rawdate = time;
var today_D = new Date(new Date().toLocaleString("en-US", {timeZone: "America/New_York"}));
var scheduled_D = new Date(rawdate);
var time_af = Math.abs(scheduled_D - today_D) / 36e5;
ScriptApp.newTrigger("makeCall").timeBased().after(time_af * 60 *60 * 1000).create();
}
return status;
}
makeCall()
function makeCall(status) {
var scriptProperties = PropertiesService.getScriptProperties();
var tempfileId = scriptProperties.getProperty('AUDIO'); // Modified
var number = scriptProperties.getProperty('NUMBER_CALL');
var group = scriptProperties.getProperty('GROUP_CALL');
var name = scriptProperties.getProperty('FILE_NAME');
var fullNumber;
if(group){
var ss = SpreadsheetApp.openById('xxxxxxxxxxxxxxxxxxx');
var sheet = ss.getSheetByName(group)
var length = sheet.getLastRow();
var values = sheet.getRange(1, 1, length).getValues();
fullNumber = values.flat();
}else{
var num = number;
var prefix = '+1';
var removeDashes = num.replace(/-/g,"");
var format = prefix + removeDashes;
var comma = format.replace(/ /g, ' +1');
fullNumber = comma.split(' ')
}
var folder = DriveApp.getFolderById('xxxxxxxxxxxxxxxxxxxxxx');
var tempFile = DriveApp.getFileById(tempfileId); // Added
var text = tempFile.getBlob().getDataAsString(); // Added
tempFile.setTrashed(true); // Added
var blob = text.split(","); // Modified
var blob = Utilities.newBlob(Utilities.base64Decode(blob[1]), 'audio/mpeg', name);
var file = folder.createFile(blob);
file.setSharing(DriveApp.Access.ANYONE_WITH_LINK, DriveApp.Permission.VIEW);
var id = file.getId();
for (var i = 0; i < fullNumber.length; i++){
var callsUrl = "https://api.twilio.com/2010-04-01/Accounts/ACxxxxxxxxxxxxxxxx/Calls.json";
var payload = {"To": fullNumber[i],"From" : "+177777777","Twiml" : "<Response><Play>https://docs.google.com/uc?export=play&id=" + id + "</Play></Response>"};
var options = {"method" : "post","payload" : payload};
options.headers = {"Authorization" : "Basic " + Utilities.base64Encode("xxxxxxxxxxx:xxxxxxxx")};
UrlFetchApp.fetch(callsUrl, options);
}
scriptProperties.deleteProperty('AUDIO');
scriptProperties.deleteProperty('NUMBER_CALL');
scriptProperties.deleteProperty('GROUP_CALL');
scriptProperties.deleteProperty('FILE_NAME');
return status;
}
Pattern 2:
In this pattern, content is saved to a file as the decoded data and that is used in the function of makeCall().
triggerCall()
function triggerCall(group, number, content, time, now, name){
var scriptProperties = PropertiesService.getScriptProperties();
var folder = DriveApp.getFolderById('xxxxxxxxxxxxxxxxxxxxxx'); // Added
var blob = content.split(","); // Added
var blob = Utilities.newBlob(Utilities.base64Decode(blob[1]), 'audio/mpeg', name); // Added
var file = folder.createFile(blob); // Added
scriptProperties.setProperties({'GROUP_CALL': group,'AUDIO': file.getId(),'NUMBER_CALL': number,'FILE_NAME': name}); // Modified
var status;
if(now){
status = 'Call Sent';
}else{
status = 'Call Scheduled';
}
if(now){
return makeCall(status);
}else{
var rawdate = time;
var today_D = new Date(new Date().toLocaleString("en-US", {timeZone: "America/New_York"}));
var scheduled_D = new Date(rawdate);
var time_af = Math.abs(scheduled_D - today_D) / 36e5;
ScriptApp.newTrigger("makeCall").timeBased().after(time_af * 60 *60 * 1000).create();
}
return status;
}
makeCall()
function makeCall(status) {
var scriptProperties = PropertiesService.getScriptProperties();
var fileId = scriptProperties.getProperty('AUDIO'); // Modified
var number = scriptProperties.getProperty('NUMBER_CALL');
var group = scriptProperties.getProperty('GROUP_CALL');
var name = scriptProperties.getProperty('FILE_NAME');
var fullNumber;
if(group){
var ss = SpreadsheetApp.openById('xxxxxxxxxxxxxxxxxxx');
var sheet = ss.getSheetByName(group)
var length = sheet.getLastRow();
var values = sheet.getRange(1, 1, length).getValues();
fullNumber = values.flat();
}else{
var num = number;
var prefix = '+1';
var removeDashes = num.replace(/-/g,"");
var format = prefix + removeDashes;
var comma = format.replace(/ /g, ' +1');
fullNumber = comma.split(' ')
}
var file = DriveApp.getFileById(fileId); // Modified
file.setSharing(DriveApp.Access.ANYONE_WITH_LINK, DriveApp.Permission.VIEW);
var id = file.getId();
for (var i = 0; i < fullNumber.length; i++){
var callsUrl = "https://api.twilio.com/2010-04-01/Accounts/ACxxxxxxxxxxxxxxxx/Calls.json";
var payload = {"To": fullNumber[i],"From" : "+177777777","Twiml" : "<Response><Play>https://docs.google.com/uc?export=play&id=" + id + "</Play></Response>"};
var options = {"method" : "post","payload" : payload};
options.headers = {"Authorization" : "Basic " + Utilities.base64Encode("xxxxxxxxxxx:xxxxxxxx")};
UrlFetchApp.fetch(callsUrl, options);
}
scriptProperties.deleteProperty('AUDIO');
scriptProperties.deleteProperty('NUMBER_CALL');
scriptProperties.deleteProperty('GROUP_CALL');
scriptProperties.deleteProperty('FILE_NAME');
return status;
}
Note:
In this modified script, when a file is uploaded, content is saved as a temporal file and the file ID is put to the PropertiesService. When makeCall is run, content is retrieved by the file ID and convert to the blob and saved it as a file. And the temporal file is removed. By this, the limitation of PropertiesService can be cleared.
But, in the current stage, the maximum blob size of Google Apps Script is 50 MB (52,428,800 bytes). So when the uploaded file size is over 50 MB, an error occurs. In this case, the file is converted to the base64 data. So, the maximum size is the size of base64 data. Please be careful this.

Javascript: Calling private in a outside javascript file with JSON data

I am trying to call the method getTitulo, getDuracion and getLink inside the cancion.js file but when i call the function it returns the following error: "listaCanciones_Lcl[i].getTitulo is not a function". I have searched in different websites but i didnt got lucky with finding an answer. Hopefully someone here can give me some help, i will gladly appreciate it!
//Logic.js file
var listaCanciones = [],
ejecuTitulo = '',
ejecuDuracion = '',
ejecuLink = '';
var btnGenerarLista = document.getElementById("addList").addEventListener("click", agregarCanc);
var btnAgregarLista = document.getElementById("gnrList").addEventListener("click", llenarTabla);
function agregarCanc (){
var nameSong = document.querySelector('#nameSong').value;
var duraSong = document.querySelector('#duraSong').value;
var linkSong = document.querySelector('#linkSong').value;
var objCancion = new Cancion(nameSong, duraSong, linkSong);
listaCanciones.push(objCancion);
var listaCancionesJson = JSON.stringify(listaCanciones);
localStorage.setItem('json_canciones', listaCancionesJson);
}
function llenarTabla (titulo){
var celdaTitulo = document.querySelector('#tituloList'),
celdaDuracion = document.querySelector('#duracionList'),
celdaLink = document.querySelector('#linkList'),
listaCanciones_Lcl = JSON.parse(localStorage.getItem('json_canciones'));
for(var i=0; i<listaCanciones_Lcl.length;i++){
// Acceder a lista canciones
I am getting an error in this line, where is says "getTitulo" is not a function but i dont really know why?
var nodoTextoTitulo = document.createTextNode(listaCanciones_Lcl[i].getTitulo()),
nodoTextoDuracion = document.createTextNode(listaCanciones_Lcl[i].getDuracion()),
nodoTextoLink = document.createTextNode(listaCanciones_Lcl[i].getLink());
// Create td
var elementoTdTitulo = document.createElement('td'),
elementoTdDuracion = document.createElement('td'),
elementoTdLink = document.createElement('td');
// Celda Id Append Child
elementoTdTitulo.appendChild(nodoTextoTitulo);
elementoTdDuracion.appendChild(nodoTextoDuracion);
elementoTdLink.appendChild(nodoTextoLink);
// Fila Append Child
celdaTitulo.appendChild(elementoTdTitulo);
celdaDuracion.appendChild(elementoTdDuracion);
celdaLink.appendChild(elementoTdLink);
}
}
//Cancion.js File
var Cancion = function(pTitulo, pDuracion, pLink){
var id = 0;
var titulo = pTitulo;
var duracion = pDuracion;
var link = pLink;
this.getId = function (){
return id;
};
this.setTitulo = function (pTitulo){
titulo = pTitulo;
};
this.getTitulo = function(){
return titulo;
};
this.setDuracion = function(pDuracion){
duracion = pDuracion;
};
this.getDuracion = function(){
return duracion;
};
this.setLink = function (pLink){
link = pLink;
};
this.getLink = function(){
return link;
};
};
First, make sure you are loading the Cancion.js file before the others in your HTML. Your problem is that when you parse the JSON back out of local storage, Cancion is not a known object, so getTitulo is undefined. You'll have to do listaCanciones_Lcl[i].titulo; instead.
And another change you'll need is to loosen the scope of your variables. The reason you need this.x = pX is because before JSON.stringify(new Cancion(1, 2, 3)) just returned "{}". With this code it returns "{"id":0,"titulo":1,"duracion":2,"link":3}", which I think is what you were after.
function Cancion(pTitulo, pDuracion, pLink){
this.id = 0;
this.titulo = pTitulo;
this.duracion = pDuracion;
this.link = pLink;
this.getId = function (){
return this.id;
};
this.setTitulo = function (pTitulo){
this.titulo = pTitulo;
};
this.getTitulo = function(){
return this.titulo;
};
this.setDuracion = function(pDuracion){
this.duracion = pDuracion;
};
this.getDuracion = function(){
return this.duracion;
};
this.setLink = function (pLink){
this.link = pLink;
};
this.getLink = function(){
return this.link;
};
};
var objWithFunction = {
name: 'Object with Function',
getName: function() { return this.name }
};
undefined
objWithFunction.getName() // --> "Object with Function"
var string = JSON.stringify(objWithFunction)
string // -=> "{"name":"Object with Function"}"
JSON is for data only..
Better you create a model, and fill it with data.. but this model has to exist in your application.. or you load the model parallel to your data..
function SomeThing() {};
SomeThing.prototype.getName = function() { return this.name };
var Thing1 = new SomeThing(JSON.parse("{name:'ThingOne'}"));
Thing1.getName(); // ThingOne

Javascript object become undefined on recordset

I have an acces database and I would like to import data to javascript.
This is my code:
function Flight(){
this.number;
this.day;
this.updateDate;
this.html;
}
var dbPath = "mypath\\flight_bdd.mdb";
var flights = [];
function executeRequest(request){
//get datas
var adoConn = new ActiveXObject("ADODB.Connection");
var adoCmd = new ActiveXObject("ADODB.Command");
adoConn.Open("Provider=Microsoft.Jet.OLEDB.4.0;Data Source='" + dbPath + "'");
adoCmd.ActiveConnection = adoConn;
var adOpenDynamic=2;
var adLockOptimistic=3;
var rs = new ActiveXObject("ADODB.Recordset");
rs.open(request, adoConn, adOpenDynamic, adLockOptimistic);
return rs;
}
function loadFlightsFromDatabase(){
//get datas
var rs = executeRequest("SELECT * FROM flight_data");
//empty flight array
flights = [];
//create flights
var i = 0
while(!rs.eof){
flights[i] = new Flight();
//set flight data
flights[i].number = rs.fields("flight_number");
console.log(flights[i].number);
rs.MoveNext();
console.log(flights[i].number);
i++;
}
}
The first console output returns the flight number and the second one returne undefined.
I think the value of the recordset is updated in my object when I have a move next, is there a way to prevent it ?
I think your connection goes out of scope and is getting closed. Try creating a disconnected recordset:
var adOpenStatic = 3;
var adUseClient = 3;
var adLockBatchOptimistic = 4;
var rs = new ActiveXObject("ADODB.Recordset");
rs.CursorLocation = adUseClient;
rs.open(request, adoConn, adOpenStatic, adLockBatchOptimistic);
rs.ActiveConnection = null;
adoConn.Close;
return rs;
But that said, rs.MoveNext(); should not affect already assigned property of your object (unless it's a reference type). What type is .number - can u show structure of Flight?
I find a solution,
I I concatenate my recordset
flights[i].number = rs.fields("flight_number") + "";
it works !!

Sorting the results of an indexedDB query

I want to sort results obtained from indexedDB.
Each record has structure {id, text, date} where 'id' is the keyPath.
I want to sort the results by date.
My current code is as below:
var trans = db.transaction(['msgs'], IDBTransaction.READ);
var store = trans.objectStore('msgs');
// Get everything in the store;
var keyRange = IDBKeyRange.lowerBound("");
var cursorRequest = store.openCursor(keyRange);
cursorRequest.onsuccess = function(e) {
var result = e.target.result;
if(!!result == false){
return;
}
console.log(result.value);
result.continue();
};
Actually you have to index the date field in the msgs objectStore and open an index cursor on the objectStore.
var cursorRequest = store.index('date').openCursor(null, 'next'); // or prev
This will get the sorted result. That is how indexes are supposed to be used.
Here's the more efficient way suggested by Josh.
Supposing you created an index on "date":
// Use the literal "readonly" instead of IDBTransaction.READ, which is deprecated:
var trans = db.transaction(['msgs'], "readonly");
var store = trans.objectStore('msgs');
var index = store.index('date');
// Get everything in the store:
var cursorRequest = index.openCursor();
// It's the same as:
// var cursorRequest = index.openCursor(null, "next");
// Or, if you want a "descendent ordering":
// var cursorRequest = index.openCursor(null, "prev");
// Note that there's no need to define a key range if you want all the objects
var res = new Array();
cursorRequest.onsuccess = function(e) {
var cursor = e.target.result;
if (cursor) {
res.push(cursor.value);
cursor.continue();
}
else {
//print res etc....
}
};
More on cursor direction here: http://www.w3.org/TR/IndexedDB/#cursor-concept
IDBIndex API is here: http://www.w3.org/TR/IndexedDB/#idl-def-IDBIndex
Thanks to zomg, hughfdjackson of javascript irc, I sorted the final array. Modified code as below:
var trans = db.transaction(['msgs'], IDBTransaction.READ);
var store = trans.objectStore('msgs');
// Get everything in the store;
var keyRange = IDBKeyRange.lowerBound("");
var cursorRequest = store.openCursor(keyRange);
var res = new Array();
cursorRequest.onsuccess = function(e) {
var result = e.target.result;
if(!!result == false){
**res.sort(function(a,b){return Number(a.date) - Number(b.date);});**
//print res etc....
return;
}
res.push(result.value);
result.continue();
};
