javascript - 对象数组，过滤掉带 0 的值

Question

我想删除值为 0 的对象的 key + value。时间戳应该保留在原位。

var array = [{
  "timestamp": "2017-01-18T00:00:00.000Z",
  "Test Bar 0": 78.09482851766388
}, {
  "timestamp": "2017-01-18T01:00:00.000Z",

var abc = array.filter((object) => {
  let keys = []
  for (let key in object) {
    if (key !== 'timestamp') keys.push(key)
  }
  return keys.map(key => object[key] > 0)
})

console.log(abc)

但是我的代码没有删除 0 个值

你的 keys.map 是错误的:

var abc = array.forEach((object) => {
  for(key in object){
    if(key!=="timestamp"&&(object[key]==0||object[key]=="0") {
        delete object[key];
     }
    }
 });
