循環到一個對象數組和對屬性的訪問

Question

我檢查了其他問題來解決這個問題，但我無法弄清楚如何解決它在我的情況：我想循環遍歷一個對象數組的所有項和訪問到一個特定的財產。

for (var i = 0; i < myArray.length; i++){ 
    var x = myArray[i].property; 
    console.log(x); 
} 

我的數據陣列結構：

var myArray = [ 
    firstObject: { 
     title:"first", 
     content:"lorem ipsum" 
    }, 
    secondObject: { 
     title:"second", 
     content:"lorem ipsum" 
    }, 
    thirdObject: { 
     title:"third", 
     content:"lorem ipsum" 
    } 
] 

檢查控制檯輸出是在myArray的對象的每個實例的列表，但它只有從它檢索的第一個對象。那麼，如何正確訪問這些值呢？由於

var myArray = 
 
[ 
 
    { 
 
     title: "first", 
 
     content: "lorem ipsum" 
 
    }, 
 
    { 
 
     title: "second", 
 
     content: "lorem ipsum" 
 
    }, 
 
    { 
 
     title: "third", 
 
     content: "lorem ipsum" 
 
    } 
 
]; 
 
var arrExpectedData = []; 
 
myArray.forEach(function (objSingle) { 
 
    arrExpectedData.push(objSingle.title); 
 
}); 
 
console.log(arrExpectedData);
