Google App Script to trigger on cell value change with email notification - google-apps-script

Question

looking for a help to fix my script in Google spreadsheets.
I want to build a function that sends an email every time a certain cell in the list is updated.
Here is my code, but it doesn't work.
Looking for your help to find and fix my issue
function onEdit(e) {
const specificSheet = "Inventory"
const specificCell = "B1"
let sheetCheck = (e.range.getSheet().getName() == specificSheet)
let cellCheck = (e.range.getA1Notation() == specificCell)
if (!(sheetCheck && cellCheck)) {
return
}
else {
sendEmail(){
var subject = "New update";
var emailAddress = "example#gmail.com";
var message = "new update: link";
MailApp.sendEmail(emailAddress, subject, message)
}
}
}

Answer 1

Send email on an Edit
function onMyEdit(e) {
const sh = e.range.getSheet();
if (sh.getName() = "Inventory" && e.range.columnStart == 2 && e.range.rowStart == 1) {
var subject = "New update";
var emailAddress = "example#gmail.com";
var message = "new update: link";
MailApp.sendEmail(emailAddress, subject, message)
}
}
I think this needs to be an installable trigger in order to send an email.

Sometimes Sheet can not process complex operations related to onEdit(e), so maybe this could help:
function onEdit(e) {
const specificSheet = "Inventory";
const specificCell = "B1";
var range = e.range;
var ss = e.source;
var sheetName = ss.getActiveSheet().getName();
var a1Notation = range.getA1Notation();
if ((sheetName==specificSheet) && (a1Notation==specificCell)) {
var props = PropertiesService.getScriptProperties();
props.setProperty("CHECKED","TRUE");
}
}
function sendEmail(){
var subject = "New update";
var emailAddress = "example#gmail.com";
var message = "new update: link";
var props = PropertiesService.getScriptProperties();
var checked = props.getProperty("CHECKED");
if (checked == "TRUE"){
GmailApp.sendEmail(emailAddress, subject, message);
Utilities.sleep(3000);
props.setProperty("CHECKED","FALSE");
}
}
Another thing you should do is setting sendEmail() function is activated by time trigger every minute or so...
