[英]trying to create an array of objects given 2 arrays + map
I have the following 2 arrays here: 我在这里有以下两个数组:
> chNameArr
[ 'chanel1',
'chanel2',
'chanel3',
'chanel4',
'chanel5',
'chanel6',
'chanel7' ]
and here: 和这里:
> a
[ 'channelName'
'status',
'connections',
'socketIds',
'lastRun',
'numberOfRuns',
'timeout' ]
what I am trying to achieve is the following objects per channel in an array where channelName
from a
get the value from chNameArr
but the rest of 'a' gets an empty string 我试图做到的,是在一个阵列每个通道中的下列对象,其中
channelName
从a
来自获得的价值chNameArr
但其余“A”得到一个空字符串
file=[{"channelName":"chanel1","status":"", "connections":"", "socketIds":"", "lastRun":"", "numberOfRuns":"", "timeout":""},
.
.
.
{"channelName":"chanel7","status":"", "connections":"", "socketIds":"", "lastRun":"", "numberOfRuns":"", "timeout":""}]
this is my attempt 这是我的尝试
> chNameArr.map(function(d){return {channelName:d}})
[ { channelName: 'chanel1' },
{ channelName: 'chanel2' },
{ channelName: 'chanel3' },
{ channelName: 'chanel4' },
{ channelName: 'chanel5' },
{ channelName: 'chanel6' },
{ channelName: 'chanel7' } ]
chNameArr.map(function(d) {
result = {};
result[a[0]] = d;
for (var i=1; i<a.length; i++) {
result[a[i]] = "";
}
return result;
})
There is no one-liner to solve this problem in general, although if you don't actually need to use the array a
you could manually construct {channelName:d, status: "", ...}
in your original map. 一般而言,没有一种方法可以解决此问题,尽管如果您实际上不需要使用数组
a
,则可以在原始映射中手动构造{channelName:d, status: "", ...}
。
