钛登录/注册

Question

下面是我为云用户login...the使用的代码，很小的问题是:每当我登录和注销时，插入到textfields中的数据不会消失，我不希望它们被保存，我希望用户在注销后再次插入textfields。

//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);
    }
    });
});

我想你想要清除文本框。成功登录后，只需清空textFields即可。为此，只需按以下方式修改代码

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);
        }
    });
});

这将起到以下作用:)
