热毛巾SPA Durandal淘汰赛和Dynatree

问题描述

基于这个小提琴 http://jsfiddle，我试图使dynatree控件在Hottowel视图模型中工作.网络/EZgNs

var ViewModel = function() {
    var self = this;
    self.initialized = ko.observable(false);
    self.items = ko.observableArray();

    // Use JSFiddle echo to simulate an AJAX service
    (function() {
        $.ajax({ url:"/echo/json/", data:data, type:"POST",
                 success:function(data)
                 {
                   // Map the returned JSON to the View Model
                   ko.mapping.fromJS(data, {}, self.items);
                   self.initialized(true);
                 }
               });
     })();
};

ko.bindingHandlers.dynatree = {
    update: function(element, valueAccessor, allBindingsAccessor, viewModel) {
        setTimeout( function() { $(element).dynatree()}, 0);
    }
};

ko.applyBindings(new ViewModel());

难以理解如何编辑vm以合并dynatree ko.

Having trouble understanding how to edit the vm to incorporate the dynatree ko.

推荐答案

首先，您不应该明确绑定视图模型；让Durandal为您做到这一点.接下来，您可以通过将绑定处理程序放置在main.js或shell.js文件的activate方法中，一开始就注册任何敲除绑定处理程序.这样，您可以确保绑定处理程序在绑定时可用于所有viewmodel/view组合.

First off, you shouldn't be binding your viewmodel explicitly; let Durandal do this for you. Next, you can register any knockout binding handlers at the outset by placing the binding handler in either the main.js or the shell.js file's activate method. This way, you guarantee that the binding handler is available to all viewmodel/view combinations at binding time.
