[英]Delete keys from an array of objects in javascript
I have an array of objects as shown below我有一个对象数组,如下所示
[{
'0': 'RECORD_KEY',
'1': 'FIRST_TOUCH_DATE_TIME',
'2': 'ISA_SENDER_ID'
},
{
'0': '00208851228_1',
'1': '2020-02-19 13:08:20.0',
'2': 'CCA'
}, {
'0': ''
}
]
I want to remove the key and the last object which is null.我想删除键和最后一个为空的对象。
So the result would be -所以结果是——
[{
'0': 'RECORD_KEY',
'1': 'FIRST_TOUCH_DATE_TIME',
'2': 'ISA_SENDER_ID'
},
{
'0': '00208851228_1',
'1': '2020-02-19 13:08:20.0',
'2': 'CCA'
}
]
So each object would represent a row of data.所以每个对象都代表一行数据。 How can I possibly do this in node.js?我怎么可能在 node.js 中做到这一点?
Your desird outcome is not valid JS.你想要的结果不是有效的 JS。 What you need is a nested array(array of arrays):你需要的是一个嵌套数组(数组数组):
const arr =[
{
'0': 'RECORD_KEY',
'1': 'FIRST_TOUCH_DATE_TIME',
'2': 'ISA_SENDER_ID'
},
{
'0': '00208851228_1',
'1': '2020-02-19 13:08:20.0',
'2': 'CCA'
},
{ '0': '' }
]
const mainArr = []
for(let item of arr){
const subArr = []
for(let prop in item){
if(!item[prop]){
continue;
}
subArr.push(item[prop])
}
if(subArr.length){
mainArr.push(subArr)
}
}
