Form Input Bindings

Vue has grown by leaps and bounds over the last couple years, and overtook Angular as the 2 frontend framework in According to the State of JS surveyVue is the 1 frontend framework that isn't associated with a serial bad actorwhich makes it worth learning if you're serious about going Facebook-free. In this article, I'll walk through building a simple form with Vue. One of the major benefits of Vue is that you can get started in vanilla JavaScript, with no outside npm modules or new languages. The easiest way to get started with Vue is including it via script tag. However, for educational purposes, this article will npm install the vue npm package and create a bundle with webpack. The first step is to npm install a couple packages. In addition to vue and webpack, install serve to spin up a lightweight web server. Create an index. The content div is the element Vue will render into, and name-form is a custom component that we'll add to Vue. Here's a minimal Webpack config file webpack. Importing Vue via require is easy, but not quite trivial. Here's how you import Vue with require :. Here's the full main. The main. For this simple 'Hello, World' example, Vue's total bundle size is larger than Preact'sbut smaller than React's. Here's the bundle sizes that Webpack outputs, assuming unminified code:. Forms are much easier with two way data binding as opposed to React-style one way data flow. To add a two-way binding to the name-form component, you need to add two things to your component:. Here's the full name-form component. It has two inputs, one for firstName and one for lastName. When you click the submit button, the submit function prints out the current values for firstName and lastNameand then empties both inputs. Vue's two way data binding tracks changes on the input fields and propagates them to the firstName and lastName data properties. When submit changes firstName and lastNameVue propagates those changes to the input fields. Conceptually, Vue loops through every property in the object your data function returns, and uses JavaScript's Object. In particular, Vue methods support promises, including throwing an error when the returned promise rejects.

Building a Form with Vue.js

So right now, we have the database structured to store a many to many relationship between cafes and brew methods and a way to retrieve them. We also have a parent child relationship for cafes and parent cafes. Now we need to adjust our form so we can account for these changes. With the parent child location relationship we will need an unknown amount of location fields so we will need a dynamic form. Luckily we are using VueJS which makes dynamic forms a breeze! A heads up with this dynamic form. A lot of the functionality will be unique to roastandbrew. This will be an overhaul to the structure of the NewCafe. We have cafes. These cafes have many children, and possibly one parent. Each cafe, whether parent or child has multiple brew types. Each cafe has a unique id whether parent or child that is a row in our cafes table. The difference between the parent and child cafes are: 1. Address 2. Location Name unique to the location 3. Brew Methods. What I think think we should do is in the form, make a button that adds a new location for each of the fields that is unique to the location. This will require a restructuring of the data being sent to the server. So not only are we tweaking the form display by grouping the unique data and allowing the user to edit at will. We are also adjusting the Vuex module methods and api calls. The first thing we want to do is remove the old address fields from the data method and add a locations: [] array. We will also want to remove the old address fields from the validations and add a locations: [] array and a oneLocation validation which I will explain as we go. Our new data method should look like:. The locations array will hold all of the individual data for each location as we add it. The validations locations array will hold the validations for each location as we add it. The oneLocation validation ensures at least one location has been added to the cafe. Next, we will add a method called addLocation to our methods and call this when the component is created. The method should look like:. What this does is push a location object to our locations array in the data with the fields for name, address, city, state, zip and another array for methods available which will be brew methods. We are really going to harness some sick VueJS reactivity power. The next part of the method, pushes validations for each of the new fields we are entering.

You can use the v-model directive to create two-way data bindings on form input, textarea, and select elements. It automatically picks the correct way to update the element based on the input type. Although a bit magical, v-model is essentially syntax sugar for updating data on user input events, plus special care for some edge cases. It will always treat the Vue instance data as the source of truth. You should declare the initial value on the JavaScript side, inside the data option of your component. If you want to cater to these updates as well, use the input event instead. Use v-model instead. On iOS, this will prevent the user from being able to select the first item, because iOS does not fire a change event in this case. It is therefore recommended to provide a disabled option with an empty value, as demonstrated in the example above. For radio, checkbox and select options, the v-model binding values are usually static strings or booleans for checkboxes :. But sometimes, we may want to bind the value to a dynamic property on the Vue instance. We can use v-bind to achieve that. In addition, using v-bind allows us to bind the input value to non-string values. To guarantee that one of two values is submitted in a form i. By default, v-model syncs the input with the data after each input event with the exception of IME composition, as stated above. You can add the lazy modifier to instead sync after change events:. If you want user input to be automatically typecast as a Number, you can add the number modifier to your v-model managed inputs:. If the value cannot be parsed with parseFloatthen the original value is returned. If you want whitespace from user input to be trimmed automatically, you can add the trim modifier to your v-model -managed inputs:. Fortunately, Vue components allow you to build reusable inputs with completely customized behavior. These inputs even work with v-model!

Using schemas to generate your forms with Vue, and more!

One really important task for every web developer is to handle user input via forms and it can prove to be pretty hard to develop and maintain. Hopefully there are some libraries here to improve the way you handle them. Schemas are basically nothing more than a way to model data. You describe fields property of your data objects with meta information. It can be the type of each field, how it is stored, if it is required or optional, what will be the validation process for it…. Advantages of using schemas are numerous :. There are various specifications and formats for schemas. In this article, we will see how we can handle user input at a large scale in the front-end via form generation. We will then see how our data definition can be used on the backend to make the most of schemas in our architecture. This library will generate forms with a proprietary schema specification. First of all, install vue-form-generator :. Write a component to handle your form :. And add a schema, for instance :. As you can see, the schema specification is not a popular standard, like JSON-schema. However, you are free to use your own algorithm to transform other standards to this one! This newly created component will dynamically generate the form, according to the schema. One of the main advantages of using this tool to handle your schema is that all your data model declaration is completely detached from your code. This library also provides a way to show or hide some fields. This method should return true or false, depending on the visibility of the field. This is another feature of vue-form-generator. You will be able to warn the user if he has not filled the password field as you expect him to :. And last, but not least, this library is pretty customizable : you can add all sorts of inputs and fields, and even code your own set of input components! The community behind it already started to create some additional ones, to handle more complex data structures or more ergonomic inputs.
