view-helpers

问题 Currently in the process of converting a website from its previous templating to Angular. In the previous templating process we were using we were able to call helper methods to display data correctly. For instance: <script type="text/javascript"> $.views.helpers({ parseDate: function (jsonDate) { if (jsonDate != null) { var newDate = Utils.PrettyDate(Utils.ConvertJsonDateToJsDate(jsonDate)); return newDate; } } }); </script> <div class="post-info"> <span class="posted-date">Posted {{ :

When I try to load my web-site, I get: "The directory '/App_Code/' is not allowed because the application is precompiled."

问题 I have a view helper, let say (for simplicity's sake) def call_alert return "alert 'this should appear'" end Then I have a coffeescript file some_test_page.js.coffee which renders for an action which is called via ajax. Inside this some_test_page.js.coffee I have: <%= call_alert %> When I do an ajax call to /some_test_page , I usually would expect to get a response with the compiled javascript from the coffeescript file and an alert would occur. However, it seems the view helper I tried to

问题 I am using Ruby 1.8.7 with Rails 3.1. My application worked fine in Rails 3.0 but when I bumped it up to Rails 3.1.4, all my url helpers broke!

I have the following in my routes.rb: resources :sessions In my homepage view I have the following link_to, which errors out: <%= link_to "Login", new

问题 When I create a submit button in a ZF2 form like this: $this->add(array( 'name' => 'save_closebutton', 'attributes' => array( 'type' => 'submit', 'value' => 'Save & Move On »', 'id' => 'save_closebutton', 'class' => 'btn btn-default' ), )); and then put a formSubmit element in the view like this: echo $this->formSubmit($form->get('save_closebutton')); ZF2 renders the text in the button as Save & Move On » without rendering the character that the code represents.

问题 I have seen several examples on creating a HTML helper method for active menu items. **Summary:** Simply put, in an MVC project, using the Twitter Bootstrap, I am trying to preserve the open state of a collapsible menu when a child is selected. I am using a collapsible menu, where the parent's css (the selected item) needs to include active open if a child is selected. This will ensure that the menu is open at the right location. With the use of another HTML helper, the active item is already

问题 The doc's example implies that the context is the instance of a View without a controller . But I can't try this out with latest version, please check this jsfiddle's link. 回答1: Here is the way I would do this: http://jsfiddle.net/arasbm/ACqjt/1/ Just to clarify context of the view is set to it's controller by default. If you want to access a property of view such as flag inside the view template you would use view.flag to refer to it. I prefer to setup view class name bindings inside the

问题 In my App_code , I have a helper function called FormatTelephone(string number) in Formatter.cshtml . I tried to access it in a partial view by @Formatter.FormatTelephone(number) . When I test it, it says Compiler Error Message: CS0103: The name 'Formatter' does not exist in the current context What is the likely cause of it?
