帮助下划线 - 嵌套/包裹对象的部分 [英] help with underscore - nest/wrap parts of objects

问题描述

我想转换像

var a = [{id:1, prop1:"value1", prop2:"value2"},{id:2, prop1:"value1", prop2:"value2"}] 

进入

into

var a = [{id:1, wrap: {prop1:"value1", prop2:"value2"}},{id:2, warp:{ prop1:"value1", prop2:"value2"}}]

喜欢保留id，将其余部分移动/包裹在新属性中。



我认为这可以很容易地完成（没有克隆，删除，迭代）使用下划线和想法！？



谢谢。

like keeping the id, moving/ wrapping the rest in a new property.

I thought this could be easily done (without cloning, deleting, iterating) using underscore, and ideas!?

Thanks.

推荐答案

//used beause omit didn't work

_.mixin({
    remove: function(obj, key){
        delete obj[key];
        return obj;
    }
});

var a = [{id:1, prop1:"value1", prop2:"value2"},{id:2, prop1:"value1", prop2:"value2"}];
//transform
a = _.map(a, function(value) {
  return { id:value.id ,rows: _.remove(value, "id") };
});
