controller

问题 I usually add objects in my jsp requestScopes using Controllers. For example, if I need to list categories in "localhost/products/viewall", I simply change my ProductsController adding something like @RequestMapping("/products/viewall") public void viewCategories(Model model) { List<Category> categories = service.findAllCategories(); model.addAttribute("categories", categories); } so, this method adds a list of categories to my requestScope. I need to do the same, but for all the pages of the

问题 I have a kendo combobox @(Html.Kendo().ComboBox() .Name("ddSystems") .Filter("contains") .Placeholder("-- Select --") .BindTo((IEnumerable<SelectListItem>)ViewBag.systemList) ) Onchange, a textbox is loaded in ajax. A submit button posts the textbox value and combobox value to the controller. When I get back to the view, I need ddSystems to be reset to empty. I used $('#ddSystems').data('kendoComboBox').value(null) and $('#ddSystems').data('kendoComboBox').text('') but it always retains the

问题 This is a followup to my question here: Why are my "replacement parameters" getting transformed into empty strings? Okay, maybe somebody can help me understand what's going on here (note that I didn't write this code, so I'm approaching it from the perspective of a problem bear that has just been heli-dropped into unfamiliar terrain).

问题 i was wondering whats the best way to route to pages in codeigniter? Say for example user wants to route to the index page, but should i create a method in a controller that just fo rthat page, or what is better way? 回答1: No need to create separate methods or controllers. Here's how I do it: class Pages extends CI_Controller { function _remap($method) { is_file(APPPATH.'views/pages/'.$method.'.php') OR show_404(); $this->load->view("pages/$method"); } } So the url http://example.com/pages

问题 I use Web API 2 Attribute Routing in my project to provide JSON interface over my data. I am facing weird behaviour of controller selection, not decided yet whether it's a bug or a feature :) Let me describe my approach. I would like to simulate OData syntax with help of attribute routing (direct OData usage has been refused due to design principles). For example, to get entity with id=5 I use HTTP GET request to URI http://mydomain.com/api/Entity(5) . I expect to use the same URI with HTTP

问题 Can someone help me to solve this problem. I want to pass ienumerable or just simple list of my custom viewmodel to controller. Theres my code: @model IEnumerable<WebWareApp.ViewModels.OstukorvVM> @{ ViewBag.Title = "Ostukorv"; } <h2>Hetkel ostukorvis olevad tooted:</h2> @using (Html.BeginForm("Create", "ToodeTellimuses")) { @Html.AntiForgeryToken() <table> <tr> <th>Tootenimi</th> <th>Tootegrupp</th> <th>Tootja</th> <th>Mõõdud</th> <th>Varvus</th> <th>Hind</th> <th>Vali Kogus</th> <th></th> <
