钛合金控制器构造器没有暴露函数[英] Titanium Alloy Controller Constructor doesn't exposer functions

问题描述

I am creating a row made from a widget dynamically from another controller. While I seem to have access to the views I cannot access the exported functions.

Here is the controller code for the widget.

var moment = require("/lib/moment-with-locales");
var args = $.args;
var isSent = true;

function configure(data){
    $.userImage.image = data.otherUser.attributes["avatar-thumb-url"];
    $.userNameLabel.text = Alloy.Globals.getFormattedName(data.otherUser.attributes["first-name"], data.otherUser.attributes["last-name"]);
    //$.userRatingLabel.text = data.userRating;
    $.bodyLabel.text = data.messages[0].attributes.body;
    $.timeLabel.text =  new moment(data.messages[0].attributes.timestamp).fromNow();
}

function setSentStatus(sent){
    isSent = sent;
    $.statusLabel.height = 15;
    if(sent == false){
        $.statusLabel.color = Alloy.CFG.colors.red;
    } else {
        $.statusLabel.color = Alloy.CFG.colors.grey0;
    }
};

function sendMessage(){
    Alloy.Globals.fluidAPI.postMessage(JSON.stringify({
      "data": {
        "type": "message",
        "attributes": {
          "body": data.messages[0].attributes.body,
          "recipient_id": data.otherUser.id
        }
      }
    }), function(postMessageResponse){
        if(postMessageResponse){
            Ti.API.info(postMessageResponse);
        }
    });
}

exports.configure = configure;
exports.setSentStatus = setSentStatus;
exports.sendMessage = sendMessage;

configure(args.data);

When I call the "sendMessage()" function from another controller. It can't find it.

var row = Alloy.createWidget("chatDetail.chatRow", {message: {attributes:{body: $.toolbarTextArea.getValue(), timestamp: new moment().toISOString()}}, user: Alloy.Globals.currentUserData});
        Ti.API.info(row);
        controllers.push(row);
        $.tableView.appendRow(row.getView());
        $.tableView.scrollToIndex($.tableView.data[0].rows.length-1);
        row.sendMessage();

Anyone knows what I need to do to access those functions? It seems that if the widget is generated in the view XML file this issue doesn't exist.

Lets say that this is your widget .xml:

<Alloy>
    <View id="widget">
        <Label id="userNameLabel"/>
        <Label id="userRatingLabel"/>
        <Label id="bodyLabel"/>
        <Label id="timeLabel"/>
        <Label id="statusLabel"/>
    </View>
</Alloy>

In your .js controller you could add the function to your widget, or set it directly, like:

$.widget.sendMessage = sendMessage;

Call it:

var widget = Alloy.createWidget("chatDetail.chatRow",{}).getView();
widget.sendMessage();
win.add(widget);

Or to the root, if you didn't call 'getView()' yet:

$.sendMessage = sendMessage;

Call it:

var widget = Alloy.createWidget("chatDetail.chatRow",{});
widget.sendMessage();
win.add(widget.getView());
