automatic send email based on cell value & adjust with previous Script - google-apps-script

Question

How to auto send email based Column D "Today"
to Email on Column A with Subject of COlumn B and Body of Columnn C
I found a script quite similar to my condition, but it only send to a static email
Script Source
function sendEmails() {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Email"); // To only handle the trigger sheet
var startRow = 2; // First row of data to process
var numRows = 2; // Number of rows to process
// Fetch the range of cells A2:B3
var dataRange = sheet.getRange(startRow, 1, numRows, 2)
// Fetch values for each row in the Range.
var data = dataRange.getValues();
for (i in data) {
var row = data[i];
if (row[2] === "Today") { // Trigger only if Column C is "Yes"
var emailAddress = row[0]; // First column
var message = row[1]; // Second column
var subject = "Bday ==" + row[2]; // Add "Yes" although by your trigger logic it will always say yes in the email
MailApp.sendEmail(emailAddress, subject, message);
}
}
}
And is it possile to make it compatible with my previous script

this script about Dynamic Dependent Drop Down Lists
function onEdit(event)
{
var maxRows = false;
// Change Settings:
//--------------------------------------------------------------------------------------
var TargetSheet = 'Main'; // name of sheet with data validation
var LogSheet = 'Data1'; // name of sheet with data
var NumOfLevels = 4; // number of levels of data validation
var lcol = 2; // number of column where validation starts; A = 1, B = 2, etc.
var lrow = 2; // number of row where validation starts
var offsets = [1,1,1,2]; // offsets for levels
// ^ means offset column #4 on one position right.
// var maxRows = 500; // to set the last row of validation; delete this row if not needed
// =====================================================================================
SmartDataValidation(event, TargetSheet, LogSheet, NumOfLevels, lcol, lrow, offsets, maxRows);
// Change Settings:
//--------------------------------------------------------------------------------------
var TargetSheet = 'Main'; // name of sheet with data validation
var LogSheet = 'Data2'; // name of sheet with data
var NumOfLevels = 7; // number of levels of data validation
var lcol = 9; // number of column where validation starts; A = 1, B = 2, etc.
var lrow = 2; // number of row where validation starts
var offsets = [1,1,1,1,1,1,1]; // offsets for levels
// var maxRows = 500; // to set the last row of validation, delete this row if not needed
// =====================================================================================
SmartDataValidation(event, TargetSheet, LogSheet, NumOfLevels, lcol, lrow, offsets, maxRows);
}
function SmartDataValidation(event, TargetSheet, LogSheet, NumOfLevels, lcol, lrow, offsets, maxRows)
..... Etc etc
Sorry the script is so long, i got warning "your post mostly code"
i just post some of it here and you can check full script onLink Source

Answer 1

You can change the script as such to check the rows and send email based on value of column D:
function sendEmails() {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Email"); // To only handle the trigger sheet
var startRow = 2; // First row of data to process
var numRows = sheet.getLastRow()-1; // Number of rows to process
// Fetch the range of cells A2:D
var dataRange = sheet.getRange(startRow, 1, numRows, 4)
// Fetch values for each row in the Range.
var data = dataRange.getValues();
for (i in data) {
var row = data[i];
if (row[3] === "Today") { // Trigger only if Column D is "Today"
var emailAddress = row[0];
var subject = row[1];
var message = row[2];
MailApp.sendEmail(emailAddress, subject, message);
}
}
}
To use this in a trigger similar to your second script you need to create an Installable Trigger and specify the function name. For example, if you want to trigger the sending every 24 hours:
function createTimeDrivenTriggers() {
// Trigger every 24 hours.
ScriptApp.newTrigger('sendEmails')
.timeBased()
.everyHours(24)
.create();
}
