I have a custom sidebar and I want to call a custom dialog. Is there a way of notifying the sidebar when the user closes the dialog?
From the sidebar I call a method in the code.gs file using google.script.run
google.script.run
.withSuccessHandler(editDone)
.withFailureHandler(errorHandler)
.showTemplatedDialog();
showTemplatedDialog is a function in code.gs which displays the dialog:
function showDialog() {
var htmlTemplate = HtmlService.createTemplateFromFile(dialogName);
htmlTemplate.dataFromServerTemplate = dialogData;
var html = htmlTemplate.evaluate()
.setSandboxMode(HtmlService.SandboxMode.IFRAME)
.setWidth(width)
.setHeight(height);
var ui = SpreadsheetApp.getUi();
ui.showModalDialog(html, title);
}
}
The problem is that the withSuccessHandler function is called when the dialog is displayed, not when the user closes the dialog and there doesn't seem to be any way for the sidebar to be notified of the choice that the user made.
Is there a way for a dialog to communicate back to the sidebar?
Thanks to Sandy for the tip, I did use sessionStorage, but I used an event handler instead of polling.
In my sidebar I added:
$(window).on("storage", function(e) {
if (e.originalEvent.storageArea === sessionStorage) {
var message = sessionStorage.getItem('message');
$('#sample').html(message);
}
});
Then in my dialog, before closing, I write to the sessionStorage:
$('#btnClose').on("click", function() {
sessionStorage.setItem('message', 'This is the story' + new Date());
google.script.host.close();
});

Is there a way to write a google apps script so when ran, a second browser window opens to www.google.com (or another site of my choice)?
I am trying to come up with a work-around to my previous question here:
Can I add a hyperlink inside a message box of a Google Apps spreadsheet
This function opens a URL without requiring additional user interaction.
/**
* Open a URL in a new tab.
*/
function openUrl( url ){
var html = HtmlService.createHtmlOutput('<html><script>'
+'window.close = function(){window.setTimeout(function(){google.script.host.close()},9)};'
+'var a = document.createElement("a"); a.href="'+url+'"; a.target="_blank";'
+'if(document.createEvent){'
+' var event=document.createEvent("MouseEvents");'
+' if(navigator.userAgent.toLowerCase().indexOf("firefox")>-1){window.document.body.append(a)}'
+' event.initEvent("click",true,true); a.dispatchEvent(event);'
+'}else{ a.click() }'
+'close();'
+'</script>'
// Offer URL as clickable link in case above code fails.
+'<body style="word-break:break-word;font-family:sans-serif;">Failed to open automatically. Click here to proceed.</body>'
+'<script>google.script.host.setHeight(40);google.script.host.setWidth(410)</script>'
+'</html>')
.setWidth( 90 ).setHeight( 1 );
SpreadsheetApp.getUi().showModalDialog( html, "Opening ..." );
}
This method works by creating a temporary dialog box, so it will not work in contexts where the UI service is not accessible, such as the script editor or a custom G Sheets formula.
You can build a small UI that does the job like this :
function test(){
showURL("http://www.google.com")
}
//
function showURL(href){
var app = UiApp.createApplication().setHeight(50).setWidth(200);
app.setTitle("Show URL");
var link = app.createAnchor('open ', href).setId("link");
app.add(link);
var doc = SpreadsheetApp.getActive();
doc.show(app);
}
If you want to 'show' the URL, just change this line like this :
var link = app.createAnchor(href, href).setId("link");
EDIT : link to a demo spreadsheet in read only because too many people keep writing unwanted things on it (just make a copy to use instead).
EDIT : UiApp was deprecated by Google on 11th Dec 2014, this method could break at any time and needs updating to use HTML service instead!
EDIT :
below is an implementation using html service.
function testNew(){
showAnchor('Stackoverflow','http://stackoverflow.com/questions/tagged/google-apps-script');
}
function showAnchor(name,url) {
var html = '<html><body>'+name+'</body></html>';
var ui = HtmlService.createHtmlOutput(html)
SpreadsheetApp.getUi().showModelessDialog(ui,"demo");
}
There really isn't a need to create a custom click event as suggested in the bountied answer or to show the url as suggested in the accepted answer.
window.open(url)1 does open web pages automatically without user interaction, provided pop- up blockers are disabled(as is the case with Stephen's answer)
openUrl.html

}
Google Apps Script will not open automatically web pages, but it could be used to display a message with links, buttons that the user could click on them to open the desired web pages or even to use the Window object and methods like addEventListener() to open URLs.
It's worth to note that UiApp is now deprecated. From Class UiApp - Google Apps Script - Google Developers
Deprecated. The UI service was deprecated on December 11, 2014. To
create user interfaces, use the HTML service instead.
The example in the HTML Service linked page is pretty simple,
Code.gs
// Use this code for Google Docs, Forms, or new Sheets.
function onOpen() {
SpreadsheetApp.getUi() // Or DocumentApp or FormApp.
.createMenu('Dialog')
.addItem('Open', 'openDialog')
.addToUi();
}
function openDialog() {
var html = HtmlService.createHtmlOutputFromFile('index')
.setSandboxMode(HtmlService.SandboxMode.IFRAME);
SpreadsheetApp.getUi() // Or DocumentApp or FormApp.
.showModalDialog(html, 'Dialog title');
}
A customized version of index.html to show two hyperlinks
<a href='http://stackoverflow.com' target='_blank'>Stack Overflow</a>
<br/>
<a href='http://meta.stackoverflow.com/' target='_blank'>Meta Stack Overflow</a>
Building of off an earlier example, I think there is a cleaner way of doing this. Create an index.html file in your project and using Stephen's code from above, just convert it into an HTML doc.
<!DOCTYPE html>
<html>
<base target="_top">
<script>
function onSuccess(url) {
var a = document.createElement("a");
a.href = url;
a.target = "_blank";
window.close = function () {
window.setTimeout(function() {
google.script.host.close();
}, 9);
};
if (document.createEvent) {
var event = document.createEvent("MouseEvents");
if (navigator.userAgent.toLowerCase().indexOf("firefox") > -1) {
window.document.body.append(a);
}
event.initEvent("click", true, true);
a.dispatchEvent(event);
} else {
a.click();
}
close();
}
function onFailure(url) {
var div = document.getElementById('failureContent');
var link = 'Process';
div.innerHtml = "Failure to open automatically: " + link;
}
google.script.run.withSuccessHandler(onSuccess).withFailureHandler(onFailure).getUrl();
</script>
<body>
<div id="failureContent"></div>
</body>
<script>
google.script.host.setHeight(40);
google.script.host.setWidth(410);
</script>
</html>
Then, in your Code.gs script, you can have something like the following,
function getUrl() {
return 'http://whatever.com';
}
function openUrl() {
var html = HtmlService.createHtmlOutputFromFile("index");
html.setWidth(90).setHeight(1);
var ui = SpreadsheetApp.getUi().showModalDialog(html, "Opening ..." );
}

I am building a Workspace add-on (in contrast to an Editor add-on). I have successfully created a modal dialog box using the following code:
var html = HtmlService.createHtmlOutputFromFile('dialog.html')
.setWidth(600)
.setHeight(425)
.setSandboxMode(HtmlService.SandboxMode.IFRAME);
SpreadsheetApp.getUi().showModalDialog(html, 'Some title here...');
I can successfully call an Apps Script (server side) function from the dialog.html JavaScript using this syntax:
google.script.run.withFailureHandler(showError).withSuccessHandler(closeThisWindow).onAppsScriptFunction(p1, p2);
On the Apps Script side, I have the function that receives the arguments (p1, p2) from the JavaScript function:
function onAppsScriptFunction(p1, p2) {
console.log(p1 + p2);
// the following does not work
// it simply does nothing
return CardService.newCardBuilder()
.addSection(
CardService.newCardSection().addWidget(
CardService.newTextParagraph().setText("This never appears")
)
)
.build();
}
Everything works as expected, except -- the card is not updated/refreshed. I have digged through all the Apps Script documentation and I don't see how can I refresh the sidebar or card.
Is there a way to initiate a refresh / redraw / restart / anything from the client-side JavaScript. I also tried various combinations with CardService.newActionResponseBuilder() and setStateChanged(true) and setNavigation but nothing works.
Or if that's not possible, at least somehow visually act after a user closes the Modal HTML dialog?
You can only update the card from a context of an Addon trigger
In your case onAppsScriptFunction is not linked to the Addon and thus cannot update the content of the Addon sidebar.
A workaround would be to deploy your modal dialog as a WebApp.
In this case, you can call the WebApp with setOpenLink
You can prompt the Add-on to reload when the WebApp is closed with setOnClose(CardService.OnClose.RELOAD_ADD_ON))
In combination with script properties you can write something like:
Code.gs
function onAppsScriptFunction(p1, p2) {
console.log(p1 + p2);
var props = PropertiesService.getScriptProperties();
props.setProperty("update", "yes");
}
function onHomepage() {
var props = PropertiesService.getScriptProperties();
var update = props.getProperty("update");
if(update == null || update == "no"){
var url =ScriptApp.getService().getUrl();
var button = CardService.newTextButton()
.setText("Open modal dialog as WebApp")
.setOpenLink(CardService.newOpenLink()
.setUrl(url)
.setOnClose(CardService.OnClose.RELOAD_ADD_ON));
var buttonSet = CardService.newButtonSet().addButton(button)
return CardService.newCardBuilder()
.addSection(CardService.newCardSection().addWidget(buttonSet))
.build();
}
else{
props.setProperty("update", "no");
return CardService.newCardBuilder()
.addSection(CardService.newCardSection()
.addWidget(CardService.newTextParagraph().setText("This now appears")))
.build();
}
}
function doGet(){
var html = HtmlService.createHtmlOutputFromFile('dialog.html')
.setWidth(600)
.setHeight(425);
return html;
}
dialog.html:
<html>
<script>
google.script.run.withSuccessHandler(success).onAppsScriptFunction(100, 150);
function success() {
window.top.close();
}
</script>
</html>
After deploying your code as a WEbApp this sample snippet will update your Addon sidebar as desired after the opened window is closed again.
Please mind that depending on your use case you need to decide how to deploy the WebApp and which of the PropertiesServices is the most suitbale for you (script, user or document properties).

Access data in Google App Script from spread sheet modal html form
How do I handle the call back using multiple Google File Picker
What to achieve?
In a Google Sheets script, I would like to define a Files Picker that returns the data of picked up files, provided that thereon, from another part of the scripts, the caller can receive that data.
Problem:
The file picker is launched as an html Modal dialog. After searching for a while, the only solution to get the data from the script that launched the picker is from the html script code:
set the callaback of the picker to a specific function: picker.setCallback(my_callback)
or use google.script.run.my_callback (i.e. from button Done for instance)
... provided that my_callback function defined in your script gets the data.
The problem with the above is that you cannot use the same picker for multiple purposes, because:
my_callback is fixed in the html script
my_callback cannot know for what purpose the picker was initially called (i.e. should it get the content?, should it give the information to some unknown caller?).
Once it gets the data, my_callback does not know what to do with it... unless my_callback is tied to only 1 caller; which does not seem correct, as that would require to have multiple html definitions for the picker, once per each reason you may invoke it, so it can call back to the proper function.
Any ideas?
global variables in scripts get re-initialized and cannot use PropertiesService to store values other than String (so no way to store the final picker_callback through a global var).
google.script.run does not offer calls by giving the name of the server-side function as String (reference) (which discards having a function to generate the picker_dialog.html by changing the callback function).
Sample Code

function ui() {
return SpreadsheetApp.getUi();
}
function onOpen() {
ui().createMenu('ecoPortal Tools')

picker.setCallback(my_callback)
Picker callback is different from:
or use google.script.run.my_callback
The former calls a function on the frontend html while the latter calls a function in the server.
my_callback cannot know for what purpose the picker was initially called
You can send a argument to the server:
google.script.run.my_callback("readFile");
On the server side(code.gs),
fuction my_callback(command){
if(command === "readFile") Logger.log("Picker called me to readFile");
}
google.script.run does not offer calls by giving the name of the server-side function as String
Not true. Dot is used to access members of a object. You can use bracket notation to access a member as a string:
google.script.run["my_callback"]();
EDITED BY Q.ASKER:
In your case, to pass the files_data to the server side:
google.script.run.withSuccessHandler(closeIt)[my_callback](files_data);
Now, for my_callback (String variable) to be set from server side, you need to push it using templates:
function pickFile(str_callback) {
var htmlTpl = HtmlService.createTemplateFromFile('picker_dialog.html');
// push variables
htmlTpl.str_callback = str_callback;
var htmlOut = htmlTpl.evaluate()
.setWidth(600)
.setHeight(425)
.setSandboxMode(HtmlService.SandboxMode.IFRAME);
ui().showModalDialog(htmlOut, 'Select a file');
}
The two unique changes that you need to make to your picker_dialog.html:
add printing scriptlet to set my_callback (<?= ... ?>)
use the google.script.run as mentioned
var my_callback = <?= str_callback? str_callback : 'defaultPickerCallbackToServer' ?>;
/* ... omitted code ... */
function returnSelectedFilesData() {
google.script.run.withSuccessHandler(closeDialog)[my_callback](files_data);
}
Now, when you call pickFile to open the frontend picker, you are able to set a different server callback that will receive the data with the file(s) chosen by the user.
I have a form in a modal dialog. After submiting a form that dialog closes and does some actions in the background. After closing the modal dialog I also want to update html in the sidebar (without refreshing the sidebar). I have a div with "loader" id in the sidebar with class hidden (which prevents it to be visible). On modal dialog close I want to remove class hidden from the "loader" div. How do I access that "loader" div from the modal dialog template?
You could use the browser sessionStorage, set a timer, and continuously "poll" for available information.
Thanks to a comment, a variation was suggested which eliminates the need for polling:
jquery
$(window).bind('storage',
function(e){if(e.key === "newValuesWereEntered"){doSomething()}});
Script tag:
<script>
//Use a timer to keep checking for a completed action from another dialog
var theTimer;
window.setTheTimer = function() {
//To Do - Hide the Spinner
if (typeof(Storage) === "undefined") {
alert('HTML5 Storage is not supported. This App will not work in this browser. Please update your browser.');
return;
}
try {
window.sessionStorage.setItem("newValuesWereEntered","n"); //Make sure check value is reset
} catch(e) {
alert(e.error + ' You may have this apps cookies blocked in this browser, and/or this browser tab. Check cookie blocking.');
return;
};
theTimer = window.setInterval(monitorForTheResponse, 500); //Every 1/2 second, check for response value
};
window.monitorForTheResponse = function() {
var was_a_newValueEntered,dlgInfo;
was_a_newValueEntered = window.sessionStorage.getItem("newValuesWereEntered");
if (was_a_newValueEntered === 'y') {//Dialog just wrote value to window.sessionStorage
window.sessionStorage.setItem("newValuesWereEntered","n");//Reset
clearTimeout(theTimer);//turn off timer
//Get submitted values
dlgInfo = window.sessionStorage.getItem("newValuesToTransfer");
//To Do - Run code to display new value
};
};
</script>
The dialog that has the value to pass to the sidebar must save that value to session storage
window.theValueWasSavedOrEntered = function() {
var arry,objectOfNewValues,strJSON;
try{
if (typeof(Storage) !== "undefined") {//Browser has local storage
window.sessionStorage.setItem("newValuesWereEntered","y"); //Set to yes
objectOfNewValues = {};
objectOfNewValues.valueOne = arry[0];
objectOfNewValues.valueTwo = arry[1];
strJSON = JSON.stringify(objectOfNewValues);
window.sessionStorage.setItem("newValuesWereEntered","y"); //Set to yes
window.sessionStorage.setItem("newValuesToTransfer", strJSON);
};
google.script.host.close();
} catch(e) {
SendErr({'message':'ERROR: ' + e.stack + ' message: ' + e.message});
};
};
