我是新來的主幹,並試圖通過綁定獲取模型更新來更新我的html,但沒有運氣。我正在使用jquery.window插件來創建彈出窗口。檢查我按更改標題按鈕並更新我的模型標題,HTML不會更新。真的很感謝所有幫助,謝謝backbone.js binding的問題

HTML:
<!DOCTYPE html>
<html>
<head>
<title>I have a back bone</title>
</head>
<body>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>

的Javascript:
(function($) {
AppWindow = Backbone.Model.extend({
title : "John",
window : null
});
AppWindows = Backbone.Collection.extend({
initialize : function(models, options) {
this.bind("add", options.view.addWindowView);
}
});
WindowView = Backbone.View.extend({
initialize : function(){
_.bindAll(this, "render");
this.model.bind("change:title");
this.template = _.template($("#search_template").html());
this.render().el;
},
render : function(){
var formString = this.template(this.model.toJSON());
var win = $.window({
icon : 'http://www.fstoke.me/favicon.ico',
title : this.model.get("title"),
content : formString,
x : 80,
y : 80,
resizable : true,
});
this.el = $("#" + win.getWindowId()+".window_frame");
this.delegateEvents(this.events);
return this;
}
});
AppView = Backbone.View.extend({
views: {},
el : $("body"),
initialize : function() {
this.appWindows = new AppWindows(null, {
view : this
});
},
events : {
"click #add-window" : "addWindow",
"click #change-title" : "changeTitle"
},
addWindow : function() {
var window_title = "Eric";
var window_model = new AppWindow({
title : window_title
});
// Add a new model to our friend collection
this.appWindows.add(window_model);
},
changeTitle : function(){
var win = this.appWindows.at(0);
win.set("title", "jamjamajm");
},
addWindowView : function(model) {
var view = new WindowView({
model : model
});
model.set("window", view);
},
deleteWindow : function(wnd){
console.log("deleteing");
}
});
var appview = new AppView;
})(jQuery);
'this.model.bind(「change:title」);'這裏忘了什麼? 'this.model.bind(「change:title」,this.render)如何?''? – jakee 2012-07-25 12:08:15
