问为什么for循环不将变量作为值：

EN

function newEmailAddressList(){

 var ss = SpreadsheetApp.getActiveSpreadsheet();
 var sheet = ss.getSheetByName("NewEmails");
 var range = sheet.getRange("A3:Q");
 var varRange = sheet.getRange("A2:G2");
 var addrA = [];



 range.clearContent(); //May need to change this to my delete function to speed things up.

 var contact = ContactsApp.getContacts();       //var contact = ContactsApp.getContacts();

 //////////

  for(var i = 0; i < contact.length; i++){      //for(var i = 0;i < contact.length;i++){

   //var addrA = [];                             //var addrA = []; This can't be here. It is not global or accessable if it is in this loop and the other global version doesn't access it apparently

   var addresses = contact[i].getEmails();     // var addresses = contact[i].getEmails();  

   for(var j = 0;j < addresses.length; j++){    //for(var j = 0;j < addresses.length;j++) {                           

      var address = addresses[j].getAddress();                //   s += addresses[j].getAddress() + br;

     addrA.push(address);                       //   
    }; 


}; /////////////////////AT THIS POINT CONTACTS ARRAY IS COMPLETE/////////////////////////

 var joinAddr = addrA.join();
 //var lowerAddr = joinAddr.toLowerCase();
