我可以使用下划线、jquery 或普通 js 将其转换为列表：

  ...
]

With underscore.js

使用 underscore.js

myList = _.map(_.pairs(myObject), function(n){
     return {label: n[0], value: n[1]}
});

Or with plain JavaScript

或者使用纯 JavaScript

myList = Object.keys(myObject).map(function(key){
    return {label: key, value: myObject[key]}
});

You can use mapto transform the object into the required form:

您可以使用map将对象转换为所需的形式：

    var myList = _.map(myObject, function(value, key){
        return {
            label: key,
            value: value
        }
    });
