删除包含4个或更多数字的所有行

使用regex只返回数字,然后进行计数。如果4个或更多,请删除:

function removeKeywords() {
  var sheet = SpreadsheetApp.getActiveSheet();
  var rows = sheet.getDataRange();
  var numRows = rows.getNumRows();
  var values = rows.getValues();
  var rowsDeleted = 0;
  for (var i = 0; i <= numRows - 1; i++) {
    var row = values[i];
  if (row[0].toLowerCase().indexOf("robot") > -1) {
     sheet.deleteRow((parseInt(i)+1) - rowsDeleted);
     rowsDeleted++;
  }
 var str=row[0].replace(/\D/g, '')//extract the numbers
 var len=str.length // determine lenght of number string
 if(len >=4 ){ //if 4 or more numbers delete
   sheet.deleteRow((parseInt(i)+1) - rowsDeleted);
  rowsDeleted++;
}
  }}
