如何将对象数组转换为数组数组

Question

大家好，我是 javascript 的初学者，我正在尝试将对象数组转换为 array.I 数组，尝试了一些方法，例如 Object.entries.But 我没有得到输出我 expected.If 任何人帮助的内容对 me.Any 的帮助真的很有帮助 appreciated.Thanks 提前....

My Input:

  var data=[
           {name:'TOYA',price:34},
           {name:'TOYB',price:24},
           {name:'TOYC',price:444},
           {name:'TOYD',price:54}
        ];


Expected Output:

   var data=[
           ['TOYA',34],
           ['TOYB',24],
           ['TOYC',444],
           ['TOYD',54]
        ];
     
 But I got:
 
[ [ '0', { name: 'TOYA', price: 34 } ],
  [ '1', { name: 'TOYB', price: 24 } ],
  [ '2', { name: 'TOYC', price: 444 } ],
  [ '3', { name: 'TOYD', price: 54 } ] ]
  
 using Object.entries(data);

Answer 1

var data=[
           {name:'c++',price:34},
           {name:'java',price:24},
           {name:'python',price:444},
           {name:'php',price:54}
        ];


var result = Object.values(data).map(v => Object.values(v));
console.log(result)

Answer 2

改用Object.values。

var data=[
     {name:'TOYA',price:34},
     {name:'TOYB',price:24},
     {name:'TOYC',price:444},
     {name:'TOYD',price:54}
];

var newdata = [];
for (let obj of data) {
  newdata.push(Object.values(obj));
}
console.log(newdata)

Answer 3

您可以使用 Object.values(arrayElement)

[{name:'c++',price:34},{name:'java',price:24},{name:'python',price:444},       {name:'php',price:54}].map((e)=>{return [Object.values(e)]})
