對象訪問不起作用

Question

這是代碼：

(function(Info, undefined) { 
    var createInfoTableForFeature = function (obj) { 
     var data2form = {}; 
     data2form.name = obj.name; 
     data2form.state = obj.state; 
     data2form.stateid=obj.stateId; 
     data2form.city = obj.city; 
     data2form.cityId=obj.cityId; 
     data2form.sector = obj.sector; 
     data2form.sectorId=obj.sectorId; 
     data2form.municipality = obj.municipality; 
     data2form.municipalityId=obj.municipalityId; 
     data2form.parish = obj.parish; 
     data2form.parishId = obj.parishId; 
     data2form.postcode = obj.postcode; 
    } 
    Info.copy2form = function(data){ 
     console.log(data); 
    } 
})(window.Info = window.Info || {}); 

當我打電話Info.copy2form(data2form)，data2form是undefined

Answer 1

你想data2form是全球性的，那麼你就必須刪除德var關鍵字變量data2form的聲明之前，使其全球。

如果你想讓它入店來自世界各地，但Info容器內，然後就可以像這樣把它聲明：

Info.data2form = {}; 

，然後調用你的函數是這樣的：

Info.copy2form(Info.data2form) 

Answer 2

您的文章似乎並不JSON到目前爲止相關的，很好哦。

您的data2form不存在函數外部。您應該將其分配給window.data2form或在函數外部定義var data2form。

Answer 3

這不起作用，因爲data2form是匿名函數（createInfoTableForFeature）中的局部變量。

這是1000級的解決方案之一：

function createInfoTableForFeature(obj) { 
    var data2form = {}; 
    data2form.name = obj.name; 

    data2form.state = obj.state; 
    data2form.stateid=obj.stateId; 

    data2form.city = obj.city; 
    data2form.cityId=obj.cityId; 

    data2form.sector = obj.sector; 
    data2form.sectorId=obj.sectorId; 

    data2form.municipality = obj.municipality; 
    data2form.municipalityId=obj.municipalityId; 

    data2form.parish = obj.parish; 
    data2form.parishId = obj.parishId; 

    data2form.postcode = obj.postcode; 

    return data2form; 
} 

var data2form = createInfoTableForFeature(obj); 
Info.copy2form(data2form);
