How to adjust google sheet view depending on variable? -

i have spreadsheet following script adjusts view rows according variable:

function conditionalhiderow() {   var ss = spreadsheetapp.getactivespreadsheet();   var sheet = ss.getsheetbyname("form responses 1");   var maxrows = sheet.getmaxrows()           (var = 0; < maxrows; ++i) {                           if (sheet.getrange(maxrows-i,4).getvalue() == "var1" )  {                 sheet.hiderows(maxrows-i,1)                 }             else             {               sheet.showrows(maxrows-i,1)             }         } } 

i want pass variable in page adjusts view: example

• if pass var1 in url example, rows containing var1 shown, others not
• if pass var2 in url example, rows containing var2 shown, others not

etc

i have tried function doget(e) var viewmode = e.parameter.view doesn't seem work when passing ....?view = "a"

to pass "a" doget() in url query ...?view=a; no need in apostrophes.

sample

function doget(e){   var parameter = e.parameter;   if(parameter.view){ //check off view type passed     conditionalhiderow(parater.view);   }; } function conditionalhiderow(condition){   var ss = spreadsheetapp.getactivespreadsheet();   var sheet = ss.getsheetbyname("form responses 1");   var maxrows = sheet.getdatarange().getheight();       (var = 0; < maxrows; ++i) {                       if (sheet.getrange(maxrows-i,4).getvalue() == condition )  {             sheet.hiderows(maxrows-i,1);             }           else           {             sheet.showrows(maxrows-i,1);           };    } } 

this off topic, getdatarange().getheight() experience better use, since getmaxrows() return total number of rows, if empty.

by default there 1000 empty rows, , though don't have data there, still loop through it. getdatarange().getheight() give number of last row piece of data appears.

also, curious, why looping backwards through rows?
