Titanium

Question

您好，我正在开发一个 android 应用程序测试，它使用 HTTP 协议与远程服务器和数据库进行通信。这是一个简单的登录页面。

现在我有两个控制器：index.js 和 newuser.js。

这是index.xml

<Alloy>
<Window class="container">
    <TableView>
        <TableViewRow>
            <TextField id="user" borderStyle="Ti.UI.INPUT_BORDERSTYLE_ROUNDED" color="#336699" top="10" left="10" width="250" height="60" />
        </TableViewRow>
        <TableViewRow>
            <TextField id="password" borderStyle="Ti.UI.INPUT_BORDERSTYLE_ROUNDED" color="#336699" top="10" left="10" width="250" height="60" />
        </TableViewRow>
        <TableViewRow>
            <Button id="loginBtn" onClick="doLogin" title="Login" />
        </TableViewRow>
    </TableView>

    <Menu id="menu" platform="android">

    <MenuItem id="addBook"
    title="Nuovo Utente"
    onClick="addNewuser"
    showAsAction="Ti.Android.SHOW_AS_ACTION_IF_ROOM" />
    </Menu>

    <View id="view_indicator">
        <ActivityIndicator id="ind" message="Loading..."/>
    </View>
</Window>
</Alloy>

这是index.js

loginReq = Titanium.Network.createHTTPClient();

loginReq.onload = function() {
var json = this.responseText;
var response = JSON.parse(json);
if (response.logged == true) {
    alert("it's all ok");   

} else {
    alert(response.message);
}
$.view_indicator.hide();
}

function doLogin(e) {

if ($.user.value != '' && $.password.value != '') {
    loginReq.open("POST", "http://solimeo.sviluppofacile.it/login.php");
    var params = {
        username: $.user.value,
        password: Ti.Utils.md5HexDigest($.password.value)
    };
    $.view_indicator.show();
    loginReq.send(params);
} else {
    alert("Username/Pasword are required");
};
$.user.blur();
$.password.blur();
}

function addNewuser () {

var addnewuser = Alloy.createController("newuser").getView();
addnewuser.open();

}

$.index.open();

使用此代码，一切正常。我的问题是当我尝试在 loginReq.onload、index.js.

中打开一个新控制器时

我创建了一个新控制器，loggedin.js 来显示有关用户的信息，我尝试打开它。但是控制台中有很多错误。我认为问题可能出在控制器上，但如果我调用 addNewuser() 函数，我会遇到同样的错误，该函数会调用一个经过测试的好控制器

错误是

我已经解决了问题。

我已将 $.view_indicator.hide(); 移至 if...else 区块。

所以 loginReq.onload 的正确代码是

loginReq.onload = function() {
var json = this.responseText;
var response = JSON.parse(json);
if (response.logged == true) {
    var args = {

        name: response.name,
        email: response.email
    };
    var loggedUser = Alloy.createController("loggedin", args).getView();
    loggedUser.open();
    $.view_indicator.hide();

} else {
    alert(response.message);
    $.view_indicator.hide();
}

}
