Easy j. Query Input Mask Plugin - inputmaskj. Query Input Mask is a lightweight and easy- to- use j. Query plugin that makes it easier to create an input mask. An input mask helps the user with the input by ensuring a predefined format. This can be useful for dates, numerics, phone numbers, etc. Notice how we're mixing HTML tags and components we've built. HTML components are regular React components, just like the ones you define, with one difference. The JSX compiler will automatically rewrite HTML tags to React. Categorizing and Tagging Words. Back in elementary school you learnt the difference between nouns, verbs, adjectives, and adverbs. These 'word classes' are not just the idle invention of grammarians, but are useful.

I am using this git repository for my masked input for angularjs. And I am trying to use the min and max from this but I am not having any luck so far. Tutorial (ASP. NET Core) . If you're still using ASP. NET 4 and ASP. NET MVC 5, you can follow the ASP. NET 4 tutorial instead. This tutorial covers the end- to- end process of creating a brand new ASP. NET MVC website and adding a React component in it. We will start from scratch and end with a fully functioning component. It assumes you have basic knowledge of ASP. NET MVC and using Visual Studio. This tutorial is based off the original React tutorial but has been modified specifically for React. JS. NET. We'll be building a simple, but realistic comments box that you can drop into a blog, a basic version of the realtime comments offered by Disqus, Live. Fyre or Facebook comments. We'll provide: A view of all of the comments. A form to submit a comment. Simple server- side in- memory storage for comments. It'll also have a few neat features: Optimistic commenting: comments appear in the list before they're saved on the server so it feels fast. Live updates: other users' comments are popped into the comment view in real time. Markdown formatting: users can use Markdown to format their text. Want to skip all this and just see the source? If you do not already have a copy of Visual Studio, the Community version is free. We will be using ASP. NET Core MVC. New Project #Start by creating a new ASP. NET Core MVC project: File . Currently . NET Core is missing some of the functionality provided by . NET Framework, so it is recommended to use . NET Framework unless you have a reason to use . NET Core specifically (eg. Delete the following files: Controllers\Home. Controller. cs. Views\Home and Views\Shared foldersbundleconfig. Project. This is accomplished using Nu. Get, a package manager for . NET. You can learn more about this on the Getting Started on ASP. NET Core page. Open Startup. At the top of the file, add: using. Microsoft. Asp. Net. Core. Http; using. React. Asp. Net; Directly above: // Add framework services. Add. Mvc(); Add: services. Add. Singleton< IHttp. Context. Accessor,Http. Context. Accessor> (); services. Add. React(); Directly above: Add: // Initialise React. JS. NET. Must be before static files. Use. React(config=>. This includes// your components as well as all of their dependencies.// See http: //reactjs. Example: //config// . Add. Script(. Example: //config// . Set. Load. Babel(false)// . Add. Script. Without. Transform(. To learn more about ASP. NET MVC, refer to its official website. Right- click on the Controllers folder and select Add . Right- click on the Views folder, click . Right- click on the Views\Home folder and select Add . Name the file Index. Replace the contents of the new view file with the following: @. However, to keep this tutorial simple, we will keep all HTML in the one view file. We also need to create the referenced Java. Script file (tutorial. Right- click on wwwroot\js and select Add . For our comment box example, we'll have the following component structure: - Comment. Box. - Comment. List. Comment. Form. Let's build the Comment. Box component, which is just a simple < div>. Add this code to Tutorial. Comment. Box=React. Class(. If successful, your default browser should start and you should see ! You've just built your first React component. You can leave the application running while you continue this tutorial. Simply change the JSX file and refresh to see your changes. JSX Syntax #The first thing you'll notice is the XML- ish syntax in your Java. Script. We have a simple precompiler that translates the syntactic sugar to this plain Java. Script: var. Comment. Box=React. create. Class(! Read more on the JSX Syntax article. What's going on #We pass some methods in a Java. Script object to React. Class() to create a new React component. The most important of these methods is called render which returns a tree of React components that will eventually render to HTML. The < div> tags are not actual DOM nodes; they are instantiations of React div components. You can think of these as markers or pieces of data that React knows how to handle. We are not generating HTML strings so XSS protection is the default. You do not have to return basic HTML. You can return a tree of components that you (or someone else) built. This is what makes React composable: a key tenet of maintainable frontends. React. DOM. render() instantiates the root component, starts the framework, and injects the markup into a raw DOM element, provided as the second argument. The React. DOM module exposes DOM- specific methods, while React has the core tools shared by React on different platforms (e. React Native). Composing components #Let's build skeletons for Comment. List and Comment. Form which will, again, be simple < div> s. Add these two components to your file, keeping the existing Comment. Box declaration and React. DOM. render call: var. Comment. List=React. Class(. HTML components are regular React components, just like the ones you define, with one difference. The JSX compiler will automatically rewrite HTML tags to React. Element(tag. Name) expressions and leave everything else alone. This is to prevent the pollution of the global namespace. Using props #Let's create the Comment component, which will depend on data passed in from our Comment. List component. Data passed in from the Comment. List component is available as a 'property' on our Comment component. These 'properties' are accessed through this. Using props, we will be able to read the data passed to the Comment from the Comment. List, and render some markup: var. Comment=React. create. Class(. We access named attributes passed to the component as keys on this. Component Properties #Now that we have defined the Comment component, we will want to pass it the author name and comment text. This allows us to reuse the same code for each unique comment. Now let's add some comments within our Comment. List: var. Comment. List=React. create. Class(. For example, we passed Daniel Lo Nigro (via the author attribute) and Hello React. JS. NET World (via an XML- like child node) to the first Comment. As noted above, the Comment component will access these 'properties' through this. Adding Markdown #Markdown is a simple way to format your text inline. For example, surrounding text with asterisks will make it emphasized. In this tutorial we use a third- party library remarkable which takes Markdown text and converts it to raw HTML. We already included this library with the original markup for the page, so we can just start using it. Let's convert the comment text to Markdown and output it: var. Comment=React. create. Class(. We need to convert this. React's wrapped text to a raw string that remarkable will understand so we explicitly call to. String(). But there's a problem! Our rendered comments look like this in the browser: . We want those tags to actually render as HTML. That's React protecting you from an XSS attack. There's a way to get around it but the framework warns you not to use it: var. Comment=React. create. Class(. In this case, remarkable automatically strips HTML markup and insecure links from the output. Hook up the data model #So far we've been inserting the comments directly in the source code. Instead, let's render a blob of JSON data into the comment list. Eventually this will come from the server, but for now, write it in your source: vardata=. Modify Comment. Box and the React. DOM. render() call to pass this data into the Comment. List via props: var. Comment. Box=React. Class(. To do so, we need to first create a C# class to represent our comments. Right- click on React. Demo and select Add . Once the models folder has been created, right click on it, select Add . We'll create a basic comment model: namespace. React. Demo. Models. For simplicity, we'll just modify our controller to have a hard- coded list of comments. System. Collections. Generic; using. Microsoft. Asp. Net. Core. Mvc; using. React. Demo. Models; namespace. React. Demo. Controllers. This method of defining URL routes is known as . When designing a real world API, caching of API requests should be considered more carefully. For this tutorial it is easiest to simply disable caching. If you hit /comments in your browser, you should now see the data encoded as JSON: Fetching from the server #Now that we have a data source, we can replace the hard- coded data with the dynamic data from the server. We will remove the data prop and replace it with a URL to fetch: React. DOM. render(< Comment. Boxurl=. This tutorial hard- codes it for simplicity. This component is different from the prior components because it will have to re- render itself. The component won't have any data until the request from the server comes back, at which point the component may need to render some new comments. Reactive state #So far, based on its props, each component has rendered itself once. To implement interactions, we introduce mutable state to the component. When the state updates, the component re- renders itself. The framework guarantees the UI is always consistent with the inputs. When the server fetches data, we will be changing the comment data we have. Let's add an array of comment data to the Comment. Box component as its state: var. Comment. Box=React. Class(. We'll use the standard XMLHttp. Request API to retrieve the data. If you need support for old browsers (mainly old Internet Explorer), you can use an AJAX library or a multipurpose library such as j. Query. In the following example, component. Will. Mount() loads the data from our XMLHttp. Request and assigns it to the data variable. Finally, it sets the data variable in state, using set. State(). var. Comment. Box=React. create. Class(. So, by moving the XMLHttp. Request call from component. Will. Mount(), which is executed only once before rendering, to a function called load. Comments. From. Server(), we can then call it multiple times from component. Did. Mount() at a set interval to check for any updates to the comments. The key to dynamic updates is the call to this.
