durandal

问题 I have a SPA application (durandaljs), and I have a specific route where I map the "id" of the entity that I want to fetch. The template is "/#/todoDetail/:id". For example, "/#/todoDetail/232" or "/#/todoDetail/19". On the activate function of viewmodel, I get the route info so I can grab the id. Then I create a new instance of breezejs EntityManager to get the entity with the given id. The problem is when I call manager.fetchEntityByKey("Todos", id), the EntityManager doesn't have yet the

问题 I have been studying John Papa's pluralsight course on SPA. In his main.js , he gave a name to each js library which is included in the bundle. (function () { var root = this; define3rdPartyModules(); function define3rdPartyModules() { // These are already loaded via bundles. // We define them and put them in the root object. define('jquery', [], function () { return root.jQuery; }); define('ko', [], function () { return root.ko; }); define('amplify', [], function () { return root.amplify; })

问题 I'm using Durandal in my new application and I have an issue with Durandal's dialog window (I'm using it to get some data from users). When I set width of window manually, (by default Durandal set window position from JavaScript) and if I want to have window width 600px , I need to do that through CSS with .dialog { width: 600px! important} . and that's where all the problems starts. On window resize, dialog is not responsive anymore, and when I have big form in it and window height is small,

JS code in view model, data is coming via ajax call in gridData source: groupGrid.prototype.updateGrid = function (gridDataSource, groupGridOptions) { var self = this; self.ColumnName(groupGridOption.ColumnNameList); // List of column name available in the data source. self.gridData(gridDataSource); //

问题 I'm in the middle of making this choice right now and I don't know what kinds of questions I should be asking. One that I believe is valid: Do I need SEO / natively crawlable pages? If so, stick with MVC4. One question that I'm not sure about is the impact on performance - I think this is valid: Is initial load time very important? If so, stick with MVC4 (like stackoverflow). What are some other questions that should be asked that can help point a developer in the right direction here? PS -

问题 In the shell.html for HotTowel template we have: <!--ko compose: {model: router.activeItem, afterCompose: router.afterCompose, transition: 'entrance'} --> <!--/ko--> which will automatically insert the proper view by convention. I am trying to inject different views based on the user's role in a HotTowel/Durandal App. For example, I have two Views, productEditor_Admin.html productEditor_Superviser.html (instead of these two views, I used to have only productEditor.html, by convention

问题 I'm trying to build a version of the todo app using Durandal (including Knockout + RequireJS) from a TodoMVC template. I realize that a todo app doesn't really show off the features of Durandal, but I'm on the learning path and figured it would be a good first project. Anyway, in the process I've stumbled upon an error that I'm unable to solve (see below). Error("Cannot write a value to a ko.computed unless you specify a 'write' option. If you wish to read the current value, don't pass any

问题 I have a regular anchor tag with href attribute set to "#". Normally, this prevents from any navigation but in durandal it navigates me to the home view. How can I stop it from navigating to that view? I can't change the html and stylings. It needs to be that anchor tag. But I can bind a click event to it. Is there any way to cancel navigation in anchor click event? regards 回答1: Bind a click event to it and call event.preventDefault() <a href="#" id="someAnchor">Example</a> $(function() { $('

问题 Let's say I have the following durandal code: define(['durandal/app', 'plugins/http'], function (app) { var vm = function(){ var self = this; self.myData = ko.observableArray([]); } }; vm.activate = function() { this.myData([]); }; vm.deactivate = function(){ }; return vm; }; I know by returning a constructor function, every time the view model is activated, it will return a new instance. My question is: is there anyway that when I access, if there's myData() from previous access, then I don

问题 In my HotTowel based project, I'm using Durandal 1.1.1 for routing. I have a login route, which I want to activate if the user is not logged in. my route config is like: var routes = [ { url: 'login', moduleId: 'viewmodels/login', name: 'Login', visible: true, caption: 'Login' },{ url: 'moduledetail/:id', moduleId: 'viewmodels/moduledetail', name: 'ModuleDetail', visible: true, caption: 'ModuleDetail' } I want if user want to go #/moduledetail/1 and is not authenticated yet, the browser
