I'm trying to use a sidebar with a form to get user input. The code is bound to a Google Sheets file.
Code.gs:
function onOpen() {
SpreadsheetApp.getUi()
.createMenu('Custom Menu')
.addItem('Show sidebar', 'showSidebar')
.addToUi();
}
function showSidebar() {
var html = HtmlService.createHtmlOutputFromFile('Page')
.setTitle('My custom sidebar')
.setWidth(300);
SpreadsheetApp.getUi()
.showSidebar(html);
}
function processForm(formObject) {
var ui = SpreadsheetApp.getUi();
ui.alert("This should show the values submitted.");
}
Page.html:
<!DOCTYPE html>
<html>
<head>
<base target="_top">
</head>
<body>
Please fill in the form below.<br><br>
<form id="myForm" onsubmit="google.script.run.processForm(this)">
First name:
<input type="text" name="firstname"><br><br>
Last name:
<input type="text" name="lastname"><br><br>
Gender:<br>
<input type="radio" name="gender" value="male" checked> Male<br>
<input type="radio" name="gender" value="female"> Female<br>
<input type="radio" name="gender" value="other"> Other<br>
<br>
<input type="submit" value="Submit">
</form><br>
<input type="button" value="Cancel" onclick="google.script.host.close()" />
</body>
</html>
When I press "Submit", the alert opens with the given message and my browser opens to a url which shows a blank page
(https://n-ms22tssp5ubsirhhfqrplmp6jt3yg2zmob5vdaq-0lu-script.googleusercontent.com/userCodeAppPanel?firstname=&lastname=&gender=male).
I'd like the alert to display the values submitted, and I don't want the extra page to open.
Pretty simple problem, but everything I read seems really over complicated. I just want to know the simplest way to get user input.
Here, the event is the submission of the Google Form, the effect is the function call ( onFormSubmit ). After creating the function, your script editor should look like this. Click on the stopwatch button to open the Apps Script Dashboard & create a trigger. Click on the stopwatch icon to create a trigger.
Html form has a default behavior of navigating to the submission link. To prevent that default behavior you can use event.preventDefault()
function in HTML like so:
<form id="myForm" onsubmit="event.preventDefault(); google.script.run.processForm(this)">
Note: You can find more detailed explanation here
The form elements are sent as an object in the argument to the processForm function, to view them you can use JSON.stringfy()
. Learn more about objects here
Your processForm function would be modified like so:
function processForm(formObject) {
var ui = SpreadsheetApp.getUi();
ui.alert(JSON.stringify(formObject))
// To access individual values, you would do the following
var firstName = formObject.firstname
//based on name ="firstname" in <input type="text" name="firstname">
// Similarly
var lastName = formObject.lastname
var gender = formObject.gender
ui.alert (firstName+";"+lastName+";"+gender)
}
