javascript - js根据数组中的值查找数组中对象的索引

Question

我有像callsData[]这样的数组，其中包含如下对象:

{
  "caller_id": "110",
  "Channel": "SIP/Kam-SBC-0000001c",
  "AccountCode": "1004",
  "Server": "192.168.1.36",
  "Callee": "109",
  "connected_line": "109",
  "Uniqueid": "145712272845",
  "DestChannel": "SIP/Kam-SBC-0000001d",
  "DestUniqueid": ["3432423423423","123123123","312321312"]
}

我想查找 DestUniqueid 数组中存在我的值 3432423423423 的对象的索引。

Answer 1

尝试编写一个简单的for循环，

for(var i=0;i<callsData.length;i++){
  if(callsData[i].DestUniqueid.indexOf("3432423423423") > -1)
  break;
}

console.log(i + " is the index of element with value 3432423423423");

如果你想把它作为一个函数，那么就这样写:

function getIndex(val){
 for(var i=0;i<callsData.length;i++){
  if(callsData[i].DestUniqueid.indexOf(val) > -1)
   break;
 }
 return i;
}

console.log(getIndex("3432423423423") + " is the index of element with value 3432423423423");
