在javascript中将数组合并为单个对象

object arrays javascript

Vincent Chua · 技术社区 · 6 年前

目前我有3个阵列:

var idArray = [13, 24, 35];    
var dateArray = [20181920, 20181120, 20172505];
var contentArray = ["content1", "content2", "content3"];

我希望将所有数组合并为一个对象,并尝试使用for循环,但得到了一个错误:

var finalObj = {};

for (var y = 0; y < dateArray.length; y++) { 
    finalObj[y].id = idArray[y];
    finalObj[y].date =  dateArrayArrange[y];
    finalObj[y].content =  contentArray[y];

}

我想要达到的最终结果是:

finalObj = [{id:13, date:20181920, content:"content1"},
          {id:24, date:20181120, content:"content2"},
          {id:35, date:20172505, content:"content3"}];

finalObj

var finalObj = [];
var idArray = [13, 24, 35];
var dateArray = [20181920, 20181120, 20172505];
var contentArray = ["content1", "content2", "content3"];

for (var y = 0; y < dateArray.length; y++) {
  finalObj.push(
    { id: idArray[y], date: dateArray[y], content : contentArray[y] }
  )
}

finalObj[y] = {}

for (var y = 0; y < dateArray.length; y++) {
  finalObj[y] = {}  
  finalObj[y].id = idArray[y];
  finalObj[y].date = dateArray[y];
  finalObj[y].content = contentArray[y];
}

  finalObj.push(
    { id: idArray[y], date: dateArray[y], content : contentArray[y] }
  )

index

var idArray = [13, 24, 35];
var dateArray = [20181920, 20181120, 20172505];
var contentArray = ["content1", "content2", "content3"];

let m = idArray.map(function(item, index) {
  // here the map method will push the object to an 
  // array and will return that array
  return {
    id: item,
    date: dateArray[index],
    content: contentArray[index]
  }

})
console.log(m)

            id: value,
            date: dateArray[index],
            content:contentArray[index]
        }

    });
