如何在tizen网络应用程序上获取消息正文

How to get message body on tizen web app?

我正在为tizen开发我的第一个web应用程序，无法找到如何正确获取短信正文。试着这样做：

//Initialize function
var init = function () {
    console.log("init() called");
    // add eventListener for tizenhwkey
    document.addEventListener('tizenhwkey', function(e) {
        if(e.keyName == "back")
            tizen.application.getCurrentApplication().exit();
    });    
};

$(document).ready(init);
var MyApp = {};
var smsService;
//Define the success callback.
var messageSentCallback = function(recipients) {
  console.log("Message sent successfully to " + recipients.length + " recipients.");
}
// Define the error callback.
function errorCallback(err) {
  console.log(err.name + " error: " + err.message);
}
// Define success callback
function successCallback() {
  console.log("Messages were updated");
}
//Define success callback
function loadMessageBody(message) {
    console.log ("body for message: " + message.subject + "from: " + message.from + "loaded.");
}
function messageArrayCB(messages) {
    console.log('Messages: ' + messages.length);
    for (var message in messages) {
    try{
            MyApp.smsService.loadMessageBody(message, loadMessageBody, errorCallback);
        }catch(ex) {
            console.log("Get exception: " + ex.name + ":" + ex.message);
        }
    } 
} 
function serviceListCB(services) { 
    MyApp.smsService = services[0]; 
    MyApp.smsService.messageStorage.findMessages( 
    new tizen.AttributeFilter("type", "EXACTLY", "messaging.sms"), messageArrayCB); 
} 
console.log("run"); 
tizen.messaging.getMessageServices("messaging.sms", serviceListCB, errorCallback);

但我在网络模拟器的控制台上得到了这样的输出：

run main.js:88
init() called main.js:4
Messages: 10 main.js:50
Get exception: NotFoundError:An attempt is made to reference a Node in a context where it does not exist. main.js:58

所以我在调用loadMessageBody时遇到了一个问题，因为错误消息来自以下代码：

    try{
        MyApp.smsService.loadMessageBody(message, loadMessageBody, errorCallback);
    }catch(ex) {
        console.log("Get exception: " + ex.name + ":" + ex.message);
    }

我的代码出了什么问题？

目前我无法测试它来判断出了什么问题，但我建议查看tizen.org上的教程：https://developer.tizen.org/dev-guide/2.2.1/org.tizen.web.appprogramming/html/tutorials/communication_tutorial/task_chatter_manage_message.htm

我想您也可以在SDK中找到教程应用程序（Chatter）作为示例。

我发现了问题。它来自这个循环：

for (var message in messages) {
    try{
        MyApp.smsService.loadMessageBody(message, loadMessageBody, errorCallback);
    }catch(ex) {
        console.log("Get exception: " + ex.name + ":" + ex.message);
    }
}

在消息变量中是空对象，所以我用ussual for循环替换了每个循环，它也发现不需要调用加载消息，它已经出现在消息对象中了。所以我使用这样的代码：

for (var i = 0; i < messages.lenght; i++) {
    message = messages[i];
    console.log('Body message: ' + message.body.plainText);
}
