javascript-navigator.contacts.find无法正常使用(cordova / phonegap)

我正在尝试访问电话上的联系人.我正在使用下面的代码来执行此操作,但是navigator.contacts.find无法正常工作.它不会返回错误或成功消息.如果在该行代码之后放置任何类型的警报,它将不会出现.

function read_contacts(){

var options = new ContactFindOptions( );

options.filter = "";  //leaving this empty will find return all contacts

options.multiple = true;  //return multiple results

var filter = ["displayName"];    //an array of fields to compare against the options.filter 

navigator.contacts.find(filter, successFunc, errFunc, options); //breaking the code

function successFunc( matches ){
    alert("reading contacts...");
  for( var i=0; i<matches.length; i++){
    alert( matches[i].displayName );
  }

function errFunc(){
    alert("Error finding contacts");
    }
}

}

解决方法:

Phonegap Docs

尝试这个 –

function onDeviceReady() {
    var options = new ContactFindOptions();
    options.filter = "";          // empty search string returns all contacts
    options.multiple = true;      // return multiple results
    filter = ["displayName", "name"];   // return contact.displayName 
    navigator.contacts.find(filter, onSuccess, one rror, options);
}

// onSuccess: Get a snapshot of the current contacts

function onSuccess(contacts) {
       for (var i = 0; i < contacts.length; i++) {
            console.log("Display Name = " + contacts[i].displayName);
        }
}

// one rror: Failed to get the contacts

function one rror(contactError) {
     alert('onError!');
}

尝试使用此代码查找具有显示名称的所有联系人.
