Question

这是我的数组

{ Colors: 'Blues',
  Department: 'Clearance',
  Size: [ 'Runners', 'Custom Sizes' ],
  Shape: 'Round',
  Designer: 'B. Smit',
 }

我想要输出：

{ Colors: 'Blues',
  Department: 'Clearance',
  Size: 'Runners',
  Shape: 'Round',
  Designer: 'B. Smit',
 }
{ Colors: 'Blues',
  Department: 'Clearance',
  Size: 'Custom Sizes',
  Shape: 'Round',
  Designer: 'B. Smit',
 }

我尝试了这个但没有得到结果

Answer 1

你可以做这样的事情

function convert(inp){
  var result = [];
  for(var i = 0; i< inp.Size.length; i++){
    result.push({
      Colors: inp.Colors,
      Department: inp.Department,
      Size: inp.Size[i],
      Shape: inp.Shape,
      Designer: inp.Designer
    });
  }
  return result;
}


convert({
  Colors: 'Blues',
  Department: 'Clearance',
  Size: [ 'Runners', 'Custom Sizes' ],
  Shape: 'Round',
  Designer: 'B. Smit',
});

如果您使用的是ES6或现代浏览器......

＆＃13;

const input = {
    Colors: 'Blues',
    Department: 'Clearance',
    Size: [ 'Runners', 'Custom Sizes' ],
    Shape: 'Round',
    Designer: 'B. Smit'
};

const output = input.Size.map(size => (
    Object.assign(
        {},
        input,
        {
            Size: size
        }
    )
));

alert(JSON.stringify(output, null, '\t'));

@sunnyn，尝试以下解决方案。确定它会对你有所帮助。

  var obj = { Colors: 'Blues',
              Department: 'Clearance',
              Size: [ 'Runners', 'Custom Sizes' ],
              Shape: 'Round',
              Designer: 'B. Smit',
  };

var tmpArr = [];

for(var index in obj.Size) {
    var myCustObj = {};
     for (var k in obj){
          if (obj.hasOwnProperty(k)) {
             myCustObj[k] = obj[k];
          }
     }
     myCustObj.Size = obj.Size[index];
     tmpArr.push(myCustObj);
}

console.log(tmpArr);

我想返回数组
