Apps Script: Check if range is empty and copy data - google-apps-script

Question

I'm trying to build an automated list with google sheets. The first sheet(A) is for input of production data of a week. The second sheet(B) should be the data archive. Thus i want the content from sheet A copied to sheet B and then deleted in sheet a. It should be copied in the next empty range in sheet B.
My problem must be inside the notation of the "while" or / and the "if" but nothing seems to work properly.
The while checks if sheet A is already emptied, if not the "if" function checks a specific range in sheet B if it is empty. If thats the case it should be copying the data and then delete it. Else the column of the range in sheet b is changed to the next range (spaltennummer + 6).
While troubleshooting it either stays in the while (finds no empty range?) or it runs through without any effect. I tried "== 0", "== """, isblank and so on. (every option available?). Google didnt seem able to provide me an answer...
Thanks for ur help.
Code:
function myFunction() {}
function leerzelle(){
var spaltennummer = 4;
var rangeDatenarchiv = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Tabellenblatt1").getRange(8,spaltennummer,15,5);
var rangeDateneingabe = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Dateneingabe").getRange("J8:N22");
var values = rangeDateneingabe.getValues();
while(rangeDateneingabe !== 0){
if(rangeDatenarchiv == 0) {
rangeDatenarchiv.setValues(values);
rangeDateneingabe.setValues("");
}
else{
spaltennummer = spaltennummer + 6;
}
}
}

Try this:
Code:
function leerzelle() {
var spaltennummer = 4;
// Data entry
var rangeDateneingabe = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Dateneingabe").getRange("J8:N22");
var values = rangeDateneingabe.getValues();
// While we have value in data entry sheet
while (!rangeDateneingabe.isBlank()) {
// Update archive everytime you increment in else
var rangeDatenarchiv = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Tabellenblatt1").getRange(8, spaltennummer, 15, 5);
// If archive range is blank, move values
if (rangeDatenarchiv.isBlank()) {
rangeDatenarchiv.setValues(values);
rangeDateneingabe.clearContent();
}
else {
spaltennummer = spaltennummer + 6;
}
}
}
Note:
You just can't compare a range to a number, use isBlank to check if it doesn't have values instead.
You can't use setValues("") on a range to remove the contents, use clearContent instead to delete those values.
You need to redeclare archive range everytime you loop using the incremented column number
