I have a simple webapp that show a button and when a user clicked, it will open a new window that shows a website. What I want to do is when a user clicked the button, it will get the value from my google sheet and open a new window based on that value. Then, the webapp will update the value in the google sheet with a new value.
For example:
if the value in my google sheet is "Google", it will open a window to "www.google.com" and then update the google sheet value to "other website".
I have succesfully made the function for updating the value on google sheet whenever a user clicked the button but I fail in getting the value from the code.gs/google sheet to my Javascript.
Please help.
here is my code.gs:
var url = "url"; //mygooglesheet url
var web = "";
function doGet(e) {
let tmp = HtmlService.createTemplateFromFile("index");
return tmp.evaluate();
}
function setWebsite () {
var ss = SpreadsheetApp.openByUrl(url);
var ws = ss.getSheetByName("website");
web = ws.getRange(1,1,1,1).getValue();
if (web === "Google") {
ws.getRange(1,1,1,1).setValue("Youtube");
}
else if (web === "Youtube") {
ws.getRange(1,1,1,1).setValue("Facebook");
}
else {
ws.getRange(1,1,1,1).setValue("Google");
}
}
function getWebsite() {
var ss = SpreadsheetApp.openByUrl(url);
var ws = ss.getSheetByName("website");
var web = ws.getRange(1,1,1,1).getValue();
return web;
}
my index.html:
<html>
<head>
<base target="_top">
</head>
<body>
<h1>Please Click Below</h1>
<!-- <h2><?=web?>:</h2> -->
<button id = "btn" type="submit" >Open Window</button>
<script>
document.getElementById("btn").addEventListener("click", doStuff);
var web = "";
function doStuff() {
google.script.run.getWebsite(); //dont know for sure if this is needed or not
google.script.run.setWebsite();
web = <?=web?>; //dont know for sure if this is needed or not
if (web === "Google") {
window.open("https://www.google.com/");
}
else if (web === "Youtube") {
window.open("https://www.youtube.com/");
}
else {
window.open("https://www.facebook.com/");
}
}
</script>
</body>
</html>
Right now, my webapp only open a new window to "facebook.com" and update to the next value in the code. I tried "google.script.run.withSuccessHandler(onSuccess).getWebsite()" but not successful to get the variable value from the code.gs, please help.
Thank you.
Issue:
You want to open a new tab with the URL returned by getWebsite() when the button is clicked.
Solution:
In order to handle data returned by a server-side function called by google.script.run, use the success handler. The function called by this handler will be passed the value returned by the server-side function (getWebsite()) as a parameter.
Code sample:
<html>
<head>
<base target="_top">
</head>
<body>
<h1>Please Click Below</h1>
<button id = "btn" type="submit" >Open Window</button>
<script>
document.getElementById("btn").addEventListener("click", doStuff);
function doStuff() {
google.script.run.withSuccessHandler(openWebsite).getWebsite();
}
function openWebsite(web) {
if (web === "Google") {
window.open("https://www.google.com/");
} else if (web === "Youtube") {
window.open("https://www.youtube.com/");
} else {
window.open("https://www.facebook.com/");
}
}
</script>
</body>
</html>
Note:
If the data returned by getWebsite() is supposed to remain static between the moment in which the page first loads and when the button is clicked, you could also use the approach mentioned by Mike Steelson, using template scriplets.
In html, in script section, write
<? var web = getWebsite(); ?>
and erase google.script.run.getWebsite();

According to the Google Script client side API documentation, the path to call the App Script function is google.script.run.yourFunction() so in your html file. Also you are invoking the function straight away and passing the result of it to addEventListener(), instead of passing the function itself. The script should be this:
function doSomething() {
google.script.run.userClicked();
}
document.getElementById("btn").addEventListener("click", doSomething);
I want to create a WebApp, that does the following:
User clicks button on WebApp to run script
Get User eMail
Create new Google Spreadsheet (name=eMail)
get Url of that Spreadsheet
Automatically open Url in new Tab
Step 5 is where I am stuck.
I have used window.open(url) before, however that only seems to work when you run code via a Spreadsheet. What I wanna do is displaying the button on my .html and run everything only with the WebApp but I can't do that because I can not use SpreadsheetApp.getUi() from that context.
Is there another way to do this?
Here is the Error im getting:
EDIT: Seems I had some minor mistakes in my Code.gs I think i fixed that now. Still same issue tho
Thank you guys in advance! :)
Here is some sample code:
Code.gs
function doGet(e) {
return HtmlService.createHtmlOutputFromFile("page");

const lock = LockService.getScriptLock();
lock.tryLock(5000);
if (lock.hasLock()){
var email = Session.getActiveUser().getEmail();
var url = createFile(email);
openUrl(url); //THIS ONLY WORKED FROM WITHIN SPREADSHEET
lock.releaseLock();
}
}
function createFile(email){
var newSS= SpreadsheetApp.create(email);
var file = DriveApp.getFileById(newSS.getId());
var url = file.getUrl();
return url
}
function openUrl( url ){ //HAS TO CHANGE

i've have an html file with two textboxes
1.orders
1.amount
i want that when i type a number in the orders text box
i will get the value from another column in my Google Sheet in the same row that match to to this order
this is my Code.gs code its not working
function doGet(e) {
return HtmlService.createHtmlOutputFromFile('page');
}
function getCost(oneCode){
var url = "https://docs.google.com/spreadsheets/d/1333t7lvECnmOcCnTE6gnn_RN1wrPckWpIETiPUjkUnU/edit#gid=0";
var ss = SpreadsheetApp.openUrl(url);
var ws = ss.getSheetByName("Sheet1");
var data = ws.getRange(1,1,ws.getLastRow(),2).getValues();
var ordersList = data.map(function(r){ return r[0]; });
var amountList = data.map(function(r){ return r[1]; });
var position = ordersLis.indexOf(oneCode);
if(position > -1){
return amountList[position];
} else {
return "not found";
}
}
========================
this the html code
<!DOCTYPE html>
<html>
<head>
<base target="_top">
</head>
<script>
document.getElementById("one").addEventlistener("input",doThis);
function doThis(){
var oneCode = document.getElementById("one").value;
google.script.run.withSuccessHandler(updateAmount).getCost(oneCode);
}
function updateAmount(cost){
document.getElementById("two").value = cost;
}
</script>
<body>
<div>
<input id="one" type="text">
<label for="one">orders</label>
</div>
<div>
<input disabled id="two" type="text">
<label for="two">amount</label>
</div>
</body>
</html>
I would like to propose the following modification.
Modification points:
At HTML&Javascript side,
addEventlistener is addEventListener.
When your script is used, please modify document.getElementById("one").addEventListener("input",doThis); to as follows. Because when document.addEventListener("DOMContentLoaded", function) is not used, an error occurs at addEventListener.
document.addEventListener("DOMContentLoaded", function(){
document.getElementById("one").addEventListener("input",doThis);
});
When input is used as the event type, when the inputted text is 130, 1, 13 and 130 are sent. By this, google.script.run.withSuccessHandler(updateAmount).getCost(oneCode) is run 3 times. So I think that change might be suitable for this situation.
At Google Apps Script side,
At var ss = SpreadsheetApp.openUrl(url);, openUrl is openByUrl.
I think that in your script, var position = ordersLis.indexOf(oneCode); is var position = ordersList.indexOf(oneCode);.
In your script, oneCode of getCost(oneCode) is the string type.
When above points are reflected to your script, it becomes as follows.
Modified script:
HTML&Javascript side:
<!DOCTYPE html>
<html>
<head>
<base target="_top">
</head>
<script>
document.addEventListener("DOMContentLoaded", function() {
document.getElementById("one").addEventListener("change", doThis);
});
function doThis() {
var oneCode = document.getElementById("one").value;
google.script.run.withSuccessHandler(updateAmount).getCost(oneCode);
}
function updateAmount(cost) {
document.getElementById("two").value = cost;
}
</script>
<body>
<div>
<input id="one" type="text">
<label for="one">orders</label>
</div>
<div>
<input disabled id="two" type="text">
<label for="two">amount</label>
</div>
</body>
</html>
When <script>###</script> is bottom of HTML, I think that document.addEventListener("DOMContentLoaded", function() {}) is not required to be used.
Google Apps Script side:
function doGet(e) {
return HtmlService.createHtmlOutputFromFile('page');
}
function getCost(oneCode){
var url = "https://docs.google.com/spreadsheets/d/1333t7lvECnmOcCnTE6gnn_RN1wrPckWpIETiPUjkUnU/edit#gid=0";
var ss = SpreadsheetApp.openByUrl(url);
var ws = ss.getSheetByName("Sheet1");
var data = ws.getRange(1,1,ws.getLastRow(),2).getValues();
var ordersList = data.map(function(r){ return r[0].toString(); });
var amountList = data.map(function(r){ return r[1].toString(); });
var position = ordersList.indexOf(oneCode);
if(position > -1){
return amountList[position];
}
return "not found";
}
Usage:
From your script, it seems that you are using Web Apps. When you use this script, please copy and paste the above scripts to the script editor, and please redeploy the Web Apps as new version. By this, the latest script is reflected to Web Apps. Please be careful this.
When the Web Apps is opened, please input a value to the input box and push the enter key or remove the focus from the input box. By this, addEventListener("change", doThis) is executed and doThis is run.

I have a google sheet, I want to prompt a user to select ranges to get information from, store that into an array, and then create a chart in an html popup. I have read a bit about the google.script.run functionality, and understand that without the withSuccessHandler(HTMLFunction).FunctionToCall() syntax at the end, the HTML script moves onto the next line. I have a .gs file below, and an .html file, and I was able to get the graph to work when I just entered a static array in my .gs function. However, I seem to be struggling with how to return focus to the editor to get a range, and then to bring the HTML dialog box with the chart back up and get the right data to the function that plots the chart. I saw here that I could use the google.script.host to call the editor.focus() function so the user can now select cells, but I can't seem to get the focus back to the HTML popup without calling the HTML file all over again. Here is my .gs function:
function RetrieveData(){
var ss = SpreadsheetApp.getActive();
var sheets = ss.getSheets();
var s = sheets[1];
var UI = SpreadsheetApp.getUi();
var response = UI.prompt("Please enter the first cell in the category").getResponseText();
var ir = s.getRange(response);
var n= 0;
var stored = [];
stored.push(["Income Category", "Frequency"]);
while (ir.getValue()!= "") {
n = n +1;
ir = ir.offset(1, 0);
}
ir = ir.offset(-n,0)
for(i =0; i<n;i++) {
stored.push([ir.getValue(),ir.offset(n+2,0).getValue()]);
ir = ir.offset(1, 0);
}
return stored;
}
Here is my html that is within the body (Stack Overflow is a little strict, so I am not going to go through the trouble of showing all the HTML; this is just within the body and it is what is communicating with the .gs file):
google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(getdata);
function getdata() {
google.script.run.withSuccessHandler(drawChart).RetrieveData();
google.script.host.editor.focus();
}
function drawChart(stored) {
//This apparently shows a log of the object
//console.log(stored);
var data = new google.visualization.arrayToDataTable(stored);
console.log(data);
var options = {'title':'Income',
'width':400,
'height':300,
'is3d':true};
// Instantiate and draw our chart, passing in some options.
var chart = new google.visualization.PieChart(document.getElementById('chart_div'));
chart.draw(data, options);
google.script.run.withSuccessHandler(drawChart).RetrieveData();
}
One last thing I tried was to call the
SpreadsheetApp.getUi().showModalDialog(html, "Title") function one more time, but without calling the html file all over again, and creating an endless loop, I don't seem to have a way to do that. Any idea how to accomplish this?
Here's a simple example of picking a range with a modeless dialog. With just a few extra features thrown in for good measure.
Code.gs:
function selRange()//run this to get everything started. A dialog will be displayed that instructs you to select a range.
{
var output=HtmlService.createHtmlOutputFromFile('pickRange').setWidth(300).setHeight(200).setTitle('Select A Range');
SpreadsheetApp.getUi().showModelessDialog(output, 'Range Selector');
}
function selCurRng()
{
var sso=SpreadsheetApp.getActive();
var sh0=sso.getActiveSheet();
var rg0=sh0.getActiveRange();
var rng0A1=rg0.getA1Notation();
rg0.setBackground('#777700');
return rng0A1;
}
function clrRange(range)
{
var sso=SpreadsheetApp.getActive();
var sh0=sso.getActiveSheet();
var rg0=sh0.getRange(range);
rg0.setBackground('#ffffff');
}

I have a Raspberry PI with a button attached to it.
I run a Python script on it to detect when the button is pressed.
When the button is pressed, it increment a number in a text file.
I need to display this number on a web page (Apache) and to launch a sound.
For the moment, my python script change the index.html with the value I need and I am using <meta http-equiv="refresh" content="1"> to resfresh the page.
The problem is that I need to know when the number is changing to launch the sound.
Too little information to say something concrete, but here's how I'd get around to it given the main following limitation that the page is not dynamic (no ajax).
General outline:
Put the value from the text file in a identifiable field like
<span id="myNumber">#the number from file goes here </span>
then on load with java script read the value of the field:
(planin JS)
var myNumberValue = document.getElementById('myNumber').innerHTML;
then create a cookie to store the last value on clinets machine:
document.cookie = "lastNumber="+myNumberValue;
To sum it all up: on loading the webpage launch a script that will :
check for a cookie
read a value from the coookie
(http://www.w3schools.com/js/js_cookies.asp)
read a value from the field
if a cookie exists compare the values and if the number
changed play a sound like here:
Playing audio with Javascript?
either way store the value from the field to the cookie for next
website update.
[Edit] Full working solution using local storage or cookies:
<html>
<head>
<META HTTP-EQUIV="refresh" CONTENT="5">
<script type="text/JavaScript">
function myFunction()
{
var numberDisplayed = parseInt(document.getElementById('myNumber').innerHTML);
var numberInCookie = numberDisplayed;
//lets assume that's the only data in the cookie
var tmpData = readNumber();
if(tmpData!="NaN" && tmpData!= "undefined")
{
numberInCookie = tmpData;
}
if(numberDisplayed!=numberInCookie)
{
alert("changed to from "+ numberInCookie+" to " + numberDisplayed);
}
saveNumber(numberDisplayed);
}
function readNumber()
{
if (typeof(Storage) !== "undefined") {
return localStorage.getItem("lastNumber")
} else {
var cookieData = document.cookie;
//lets assume that's the only data in the cookie
var tmpData = parseInt(cookieData.split("=")[1]);
return tmpData
}
}
function saveNumber(number)
{
if (typeof(Storage) !== "undefined") {
localStorage.setItem("lastNumber", number);
} else {
document.cookie = "lastNumber="+number;
}
}
</script>
</head>
<body onload="myFunction()">
<span id="myNumber">2</span>
</body>
</html>
[Edit 2] as the author of the question hinted he doesn't actually want to use the site refresh here's another option:
lest start a loop that will load a test file from the server as an ajax request. then the data is loaded, parsed, store it loacally as before. and set timer to trigger the refresh again.
One importatnt thing the files need to be available on the same domain / server (see HTTP access control (CORS) for more information)
