Hide Rows in a Google Spreadsheet based on first Character in a cell -

-

i working on adding functionality google spreadsheet. spreadsheet imports data web, , have formatted nicely. 1 of columns series of strings, formatted in 1 of 2 ways - string or *string * without space (basically importing italics web).

i trying come script runs when open spreadsheet, will:

  • unhide rows in spreadsheet
  • loop through spreadsheet
  • hide every row column 2(b) begins asterisk

i have following:

function onopen() {   var ss = spreadsheetapp.getactivespreadsheet();   var sheet = ss.getsheetbyname("dodh");   sheet.showrows(1, sheet.getmaxrows());   for(var i=1; i<sheet.getmaxrows()+1; ++i){     if (sheet.getrange(i, 2).getvalue().){       sheet.hiderow(i)     }   } }

i don't know how access string inside each cell, , how access characters within string. thank in advance help.

here updated code. see comments have na insight

function onopen() {   var ss = spreadsheetapp.getactivespreadsheet();   var sheet = ss.getsheetbyname("dodh");   var maxrows = sheet.getmaxrows();    //show rows   sheet.showrows(1, maxrows);    //get data clumn b   var data = sheet.getrange('b:b').getvalues();    //iterate on rows   for(var i=0; i< data.length; i++){     //compare first character, if asterisk, hide row     if(data[i][0].charat(0) == '*'){       sheet.hiderows(i+1);     }   } }
