Lodash在其他数组项中搜索数组项

Question

您好，我正在使用lodash库。

我想搜索receivedMessagesMock中的电话是否在contactsMocks电话中

如果receivedMessagesMock.phone === contactsMocks.phoneNumbers.value，我需要以相同的receivedMessagesMock位置推送contactsMocks.name.formated。

就像是

if(receivedMessagesMock[0].phone === contactsMocks.phoneNumbers.value {
 receivedMessagesMock[0].name = contactsMocks.name.formatted;
}

contactMock和receiveMessagesMock

var contactsMock = [{'id':'1','rawId':'1','displayName':'Asd','name':{'givenName':'Asd','formatted':'Asd'},'nickname':null,'phoneNumbers':[{'id':'1','pref':false,'value':'000000000','type':'mobile', 'loggedInSystem':true}],'emails':null,'addresses':null,'ims':null,'organizations':null,'birthday':null,'note':null,'photos':null,'categories':null,'urls':null},{'id':'2','rawId':'2','displayName':'Bbb','name':{'givenName':'Bbb','formatted':'Bbb'},'nickname':null,'phoneNumbers':[{'id':'3','pref':false,'value':'565 65 65 65','type':'mobile'}],'emails':null,'addresses':null,'ims':null,'organizations':null,'birthday':null,'note':null,'photos':null,'categories':null,'urls':null},{'id':'3','rawId':'3','displayName':'Ccc','name':{'givenName':'Ccc','formatted':'Ccc'},'nickname':null,'phoneNumbers':[{'id':'5','pref':false,'value':'0000000001','type':'mobile'}],'emails':null,'addresses':null,'ims':null,'organizations':null,'birthday':null,'note':null,'photos':null,'categories':null,'urls':null},{'id':'4','rawId':'4','displayName':'Ddd','name':{'givenName':'Ddd','formatted':'Ddd'},'nickname':null,'phoneNumbers':[{'id':'6','pref':false,'value':'000 00 00 01','type':'mobile'}],'emails':null,'addresses':null,'ims':null,'organizations':null,'birthday':null,'note':null,'photos':null,'categories':null,'urls':null}];

    var receivedMessagesMock = [{
        'id': 12,
        'phone': '000 00 00 01',
        'time': '15:44',
        'priority': 1,
        'response' : false
    },{
        'id': 15,
        'phone': '000 00 00 01',
        'time': '15:44',
        'priority': 1,
        'response' : false
    },{
        'id': 16,
        'phone': '000 00 00 01',
        'time': '15:44',
        'priority': 2,
        'response' : true
    }
    ];

这是使用lodash做到这一点的一种方法：

lodash.map(receivedMessagesMock, function(rmm) {
  var foundContact = lodash.find(contactsMock, function(cm) {
    return lodash.find(cm.phoneNumbers, function(pn) {
      return pn.value == rmm.phone;
    });
  });
  if (foundContact) {
    rmm.names = foundContact.name.formatted
  }
  return rmm;
});

请记住，您要求输入一个名称（单数）以插入接收到的消息中。 这意味着，无论出于何种原因，如果列表中的两个或多个联系人具有相同的号码，则以上内容将始终返回第一个匹配项。 但是，确实有可能存在多个匹配项，因此插入名称数组可能是适当的。

lodash.map(receivedMessagesMock, function(rmm) {
  var foundContacts = lodash.filter(contactsMock, function(cm) {
    return lodash.find(cm.phoneNumbers, function(pn) {
      return pn.value == rmm.phone;
    });
  });
  if (foundContacts.length > 0) {
    rmm.names = lodash.map(foundContacts, function(fcs) {
      return name.formatted
    });
  }
  return rmm;
});
