谷歌地圖API和骨幹錯誤

Question

這個錯誤比較時嘗試在我看來啓動功能PROVA：遺漏的類型錯誤：無法讀取的未定義的屬性「元素」。 錯誤發生在線路的：var =地圖新google.maps.Map（document.get.Element.By.Id（ 'pagina'），選項）;

 var HomeView = Backbone.View.extend({ 

    template: Handlebars.compile(template), 

events: { 
    "click .log_out":"log_out", 
    "click .prove":"prove", 
    'orientationchange' : 'onOrientationChange' 
    }, 

    initialize: function() { 

     console.log("inhomeview"); 

    this.render(); 



    }, 



    render: function() { 
     //var context = JSON.parse(JSON.stringify(this.model));//eliminare 
     var context=this.model; 
     var html =this.template(context); 
     console.log(html); 

     $('#pagina').empty(); 
     $('#pagina').append(this.$el.html(html)); 


     return this; 
    }, 


    onOrientationChange: function() { 
    if(window.orientation == 90 || window.orientation == -90) { 
//you are in landscape zone 
//do whatever you want to do 
     } 
    }, 












    log_out:function(){ 
     console.log("logout"); 
     Parse.User.logOut(); 
    // new AppView;//ERRORE UNDEFINED NOT A FUNCTION 
    window.location='index.html' ;//METTERE UNA NEW APPVIEW MA DA ERRORE!!! 
    }, 

    prove:function(){ 
    navigator.geolocation.getCurrentPosition(win); 
    function win(pos){ 
     console.log("gps"); 
     var el='<div>'+ pos.coords.latitude+'</div>'; 
     el+='<div>'+ pos.coords.longitude+'</div>'; 
     el+='<div>'+ pos.timestamp+'</div>'; 
     $('#pagina').html(el); 



    var lat=pos.coords.latitude; 
    var lon=pos.coords.longitude; 

    var options={ 

     center:new google.maps.LatLng(-34,150), 
     mapTypeId: google.maps.MapTypeId.ROADMAP 

    }; 

     var html=$('#pagina'); 
     console.log(html); 
    var map= new google.maps.Map(document.get.Element.By.Id('pagina'),options);// ERROR HERE  


    }; 





    } 


}); 

return HomeView; 

Answer 1

這看起來不正確：

document.get.Element.By.Id 

我希望：

document.getElementById 

這可以解釋的錯誤消息：

Uncaught TypeError: Cannot read property 'Element' of undefined.
