Cordova nicht in der Lage, Daten auf Server mit Ajax

Question

Ich bin ein Phonegap Cordova Anwendung und ich möchte POST Daten an den Server mit AJAX aber bin ich nicht in der Lage, einen Fehler zu bekommen.

Mein Beispiel-Code ist:

<script> 
     $(document).ready(function() 
     { 

     $('#frm').submit(function() 
    { 

    var username = $('#textinput').val(); 
    var username = $.trim(username); 
    var password = $('#passwordinput').val(); 
    var password = $.trim(password); 

    { 

     alert('Please enter username'); 
     return false; 

    } 
    else if(password =='') 
    { 
     alert('Please enter password'); 
     return false; 
    } 
    else 
    { 
     var user = $('[name=username]').val(); 
     var pass = $('[name=password]').val(); 

     $.ajax({ 
     type: 'POST', 
     url: 'http://eqfree***p.com/log_sb.php', 
     rossDomain: true, 
     beforeSend : function() {$.mobile.loading('show')}, 
     complete : function() {$.mobile.loading('hide')}, 
     data: { username:'user', password:'pass'}, 
     dataType: 'json', 
     success: function(data){ 
      alert(data.success); 
      alert('success'); 

     }, 
     error: function(){ 
      alert('error!'); 

     } 
    }); 
return false; 
    } 
}); 
     }); 
      </script>

versuchen Sie dieses

<script> 
$(document).ready(function() 
{ 

    $('#frm').submit(function() 
    { 

    var username = $('#textinput').val(); 
    var username = $.trim(username); 
    var password = $('#passwordinput').val(); 
    var password = $.trim(password); 

    else if(username =='')//check condition 
    { 

    alert('Please enter username'); 
    return false; 

    } 
    else if(password =='') 
    { 
    alert('Please enter password'); 
    return false; 
    } 
    else 
    { 
    //no need to re initialize 
    //var user = $('[name=username]').val(); 
    //var pass = $('[name=password]').val(); 

    $.ajax({ 
    type: 'POST', 
    url: 'http://eqfree***p.com/log_sb.php', 
    crossDomain: true, 
    beforeSend : function() {$.mobile.loading('show')}, 
    complete : function() {$.mobile.loading('hide')}, 
    data: { 'username':username, 'password':password}, 
    dataType: 'json', 
    success: function(data){ 
     alert(data.success); 
     alert('success'); 

    }, 
    error: function(){ 
     alert('error!'); 

     } 
    }); 
    return false; 
    } 
    }); 
}); 
</script>
