钛登录/注册

Question

下面是我用于我的云用户登录代码...轻微的问题是;每当我登录和注销时，插入到文本字段中的数据都不会消失......我不希望它们被保存，我希望用户在注销后再次插入文本字段。

//create textfields for sign_in page/interface 
var userNameField = Titanium.UI.createTextField({ 
color: 'black', 
hintText: 'username', 
height: 35, 
top: 120, 
left: 10, 
width: 250, 
borderStyle: Titanium.UI.INPUT_BORDERSTYLE_ROUNDED 
}); 
win.add(userNameField); 





var passwordField = Titanium.UI.createTextField({ 
color: 'black', 
hintText: 'password', 
height: 35, 
top: 160, 
left: 10, 
width: 250, 
passwordMask: true, 
borderStyle: Titanium.UI.INPUT_BORDERSTYLE_ROUNDED 
}); 
win.add(passwordField); 





var button = Titanium.UI.createButton({ 
title: 'log in', 
top: 190, 
left: 10, 
width: 100, 
height:50, 
Color:'#336699' 
}); 
win.add(button); 



//then create event listener and login user to ACS cloud server 
button.addEventListener('click', function(){ 
Cloud.Users.login({ 
    login: userNameField.value, 
    password: passwordField.value, 
}, function (e) { 
    if (e.success) { 
     var user = e.users[0]; 
alert('success'); 
    } else { 
     alert('Unable to log you in:' + e.message); 
    } 
    }); 
});

我想你想清除textfields。您只需在成功登录后清空textField。对于这一点，你只需要修改你的代码如下

button.addEventListener('click', function(){ 
    Cloud.Users.login({ 
     login: userNameField.value, 
     password: passwordField.value 
    }, function (e) { 
     if (e.success) { 
      var user = e.users[0]; 
      //Clears the TiUITextField's values 
      userNameField.value = ""; 
      passwordField.value = ""; 
      alert('success'); 
     } else { 
      alert('Unable to log you in:' + e.message); 
     } 
    }); 
}); 

这将这样的伎俩:)
