Get new in put values in a row using App script - google-apps-script

Question

How do I get the new input values in google sheet using App Script. I currently get the values when I specify which cells, but I want it to be dynamic. Please help me.
function getValuesinSheet(){
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getActiveSheet();
sheet.getRange("B1").setValue("Email");
sheet.getRange("A1").setValue("Amount");
sheet.getRange("C1").setValue("Phone Number");
sheet.getRange("D1").setValue("Email Subject");
sheet.getRange("E1").setValue("Message");
var amount = parseInt(sheet.getRange("A2").getValues()) ;
var email = String(sheet.getRange("B2").getValues());
var snumber = String(sheet.getRange("C2").getValues());
var esubject = String(sheet.getRange("D2").getValues()) ;
var emessage = String(sheet.getRange("E2").getValues());
}

(Option 1)
You can use onEdit Simple Trigger, to execute an apps script function every time a cell is being modified to read/modify your sheets.
Sample Code:
function onEdit(e){
var ss = e.source; //Get the spreadsheet
var cell = e.range; //Get the range of the edited cell
var sheet = ss.getActiveSheet(); //Get the modified sheet
var row = cell.getRow();
var col = cell.getColumn();
//valid cell are within A2:E. If row ==1 or col > 5 do nothing
if(row==1 || col > 5){
return;
}
//Get the current row's first 5 columns
//Change 2-d array to 1-d array using flat()
var rowValues = sheet.getRange(row,1,1,5).getDisplayValues().flat();
if(rowValues.filter(String).length == 5){
Logger.log("DO SOMETHING")
var amount = parseInt(rowValues[0]);
var email = rowValues[1];
var snumber = rowValues[2];
var esubject = rowValues[3];
var emessage = rowValues[4];
Logger.log(amount);
Logger.log(email);
Logger.log(snumber);
Logger.log(esubject);
Logger.log(emessage);
}
}
What it does?
Get the active sheet and active cell using the onEdit() events object
Get the active cell's row and column index (apps script used one-based as index)
Check if modified cell is within A2:E range, by checking row and column index
Get the current row values from column A:E using Sheet.getRange(row, column, numRows, numColumns) and Range.getDisplayValues()
I used Range.getDisplayValues(), since it will return a 2-d array of string. I noticed that you expect your inputs as a string and you plan to convert the amount to int using parseInt()
Use flat() to convert 2-d array to 1-d array
Check the array if all the columns are not empty using filter(), if array length is 5. Then all data in the row is complete
Note:
You can remove the condition in Step 6 if you want to process the current row's column A-E values even if some data are empty.
You can also remove the condition in Step 3 based on your preference. I just included that so that the succeeding process will only be executed when cell being modified are within A2:E
Additional Information
If you are new with Simple Triggers, you cannot debug your code by running it in the Apps Script Editor. If you want to debug your code, you need to modify a specific cell in your sheet then check the latest logs in the Executions tab.
Example:
(Option 2)
If you don't prefer to use onEdit() Simple trigger. You can just use getActiveCell() to get the current selected cell row and column index
Sample Code:
function getRowValues(){
var ss = SpreadsheetApp.getActiveSpreadsheet(); //Get the spreadsheet
var cell = ss.getActiveCell(); //Get the range of the edited cell
var sheet = ss.getActiveSheet(); //Get the modified sheet
var row = cell.getRow();
var col = cell.getColumn();
//valid cell are within A2:E. If row ==1 or col > 5 do nothing
if(row==1 || col > 5){
return;
}
//Get the current row's first 5 columns
//Change 2-d array to 1-d array using flat()
var rowValues = sheet.getRange(row,1,1,5).getDisplayValues().flat();
if(rowValues.filter(String).length == 5){
Logger.log("DO SOMETHING")
var amount = parseInt(rowValues[0]);
var email = rowValues[1];
var snumber = rowValues[2];
var esubject = rowValues[3];
var emessage = rowValues[4];
Logger.log(amount);
Logger.log(email);
Logger.log(snumber);
Logger.log(esubject);
Logger.log(emessage);
}
}
