The following editor will bring you an implementation method of using phonegap to find contacts. The editor thinks it’s pretty good, so I’ll share it with you now and give it as a reference. Let’s follow the editor and take a look.

The examples are as follows:

<!DOCTYPE html> 
<html> 
  
    <head> 
        <meta charset="UTF-8"> 
        <title>Database Example</title> 
  
        <script type="text/javascript" charset="UTF-8" src="cordova.js"></script> 
        <script type="text/javascript" charset="UTF-8"> 
            document.addEventListener("deviceready", onDeviceReady, false); 
  
            function onDeviceReady() { 
            } 
              
            function onSuccess(contacts){ 
                document.write(contacts.length+&#39;contacts found.&#39;); 
                for(var i=0;i<contacts.length;i++){ 
                    for(var j=0;j<contacts[i].emails.length;j++){ 
                        document.write("Email="+contacts[i].emails[j].email); 
                    } 
                } 
                alert(&#39;success&#39;); 
            } 
              
            function onError(error){ 
                 alert("Ooops!"); 
            } 
              
            function findContact(){ 
                var myOptions=new ContactFindOptions(); 
                myOptions.filter="gmail";//过滤 
                var myFields=["emails"];//要查询的字段 
                navigator.contacts.find(myFields,onSuccess,onError,myOptions); 
            } 
              
        </script> 
    </head> 
  
    <body> 
        <button onclick="findContact();">Find Contact</button> 
    </body> 
  
</html>
