MailApp.SendEmail script for multiple tabs - google-apps-script

Question

I have been looking how to write the script to check and run on multiple tabs. What I have now, I would need to copy/paste and set execution triggers one by one.
Script I have:
function SendEmail() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheetByName("1");
var value = sheet.getRange("F3").getValue();
var subject = "subject";
var message = "message";
if (value >0){
MailApp.sendEmail("email", subject, message);
}
}
I have this running every 8 hours (trigger run).
I am looking to add more tabs so that for each tab the script can check and send an email if the value of individual tabs is more than 0.
Any ideas on how to do this?
The value in every tab is under F3. Tab names, for example, 1,2,3,4...
Thank you!!!

This should do what you looking for if I understood the issue correctly.
function SendEmail() {
//Get the Spreadsheet
var ss = SpreadsheetApp.getActiveSpreadsheet();
//Get all Sheets in the Spreadsheet
var sheets = ss.getSheets();
//Create a variable for the email address, subject and message
var email = "";
var subject = "";
var message = "";
//Can change the starting sheet by changing the value of "i" - 0 will be the first sheet.
for (var i = 0; i < sheets.length; i++){
var sheet = sheets[i];
var value = sheet.getRange("F3").getValue();
switch(sheet.getSheetName) {
case "Sheet1":
email = "email1#domain.com";
break;
case "Sheet2":
email = "email2#domain.com";
break;
default:
value = 1
email = "yourEmailAddress#domain.com";
subject = "Message Failed to Send";
message = "There was an error sending email, please investigate";
}
if (value >0){
MailApp.sendEmail(email, subject, message);
}//END OF IF STATEMENT
}//END OF FOR LOOP
}//END OF FUNCTION
