      myfunction1: function(param1,param2){
        var doSomethingHere;
      },
      myfunction2: function(){
          ....
          var param1,param2
          .... 
          //I get an error here
          myfunction1(param1,param2).then(function(return){
             console.log(return);

揭示模块模式可以帮助解决这个问题

function(){
    var myfunction1 = function(param1,param2){
        var doSomethingHere;
    }

    var myfunction2 = function(){
          ....
          var param1,param2
          .... 
          //I get an error here
          myfunction1(param1,param2).then(function(return){
             console.log(return);
          });
    }

    return{
      myfunction1: myfunction1,
      myfunction2: myfunction2
    }
}
