转换json对象的最佳方法是什么

<div id="mypost" class="col-md-8 panel-default" ng-repeat="post in myposts ">
    <div id="eli-style-heading" class="panel-heading"><% post.user.name %></div>
    <div class="panel-body panel">
        <figure>
            <p> <% post.body %></p>
            <p>  <% post.created_at %></p>
        </figure>
        <span>
            <i style="color:red;" class="glyphicon glyphicon-remove" ng-click="deletePost(post)" ng-if="post.deletable"></i>
            <span><a href="/" data-toggle="modal" data-target="#editModal">Edit</a></span>
        </span>
    </div>
</div>

到json数组

{"id" : 1, "name": "John"}

使用javascript。

更新：我想这样做是因为在Sequelize中我必须将过滤器作为Json数组传递给运算符＆＃34;或者＃34;虽然我在Json有。

Answer 1

你可以做到

＆＃13;

let obj = {"id" : 1, "name": "John"};

let result = Object.keys(obj).map(e => {
    let ret = {};
    ret[e] = obj[e];
    return ret;
});

console.log(result);

＆＃13;

Answer 2

您可以映射单个键/值对。

＆＃13;

var object = { id: 1, name: "John" },
    result = Object.keys(object).map(k => ({ [k]: object[k] }));
    
console.log(result);

＆＃13;

Answer 3

这是for循环的例子

var arr =  {"id" : 1, "name": "John"};
var newArr = [];
for(var i in arr){
  var obj={};
  obj[i] = arr[i];
  newArr.push(obj);
}
console.log(newArr);

Answer 4

这样就可以了。

＆＃13;

let object = {"id" : 1, "name": "John"};
let jsonArr = [];

let objectKeys = Object.keys(object)
for(i=0;i<objectKeys.length; i++) {
  jsonArr[i] = {};
  jsonArr[i][objectKeys[i]] = object[objectKeys[i]];  
}

console.log(jsonArr)

＆＃13;

Answer 5

var obj = { "id": 1, "name": "John" };
var arr = [];
for (var o in obj) {
  var _obj = {};
  _obj[o] = obj[o];
  arr.push(_obj);
}

console.log(arr);
