Hope one of these choices will help you rapidly prototype your "ReactJS" ideas.
Out of the hundreds of UI frameworks out there, Material UI is a framework that has the most refined implementation of Material Design. Website Demo.
Do I even need a description here? Bootstrap is, without a doubt, the most popular UI framework that is out there. Bootstrap is one of the most advanced UI frameworks out there and has got most of the things right.
Here is a React implementation of Bootstrap 3. Website Demo GitHub. Foundation from Zurb is a very feature-rich and easily customizable library. It is one of the most popular UI frameworks that are out there. Website GitHub. MDL is a light weight material design CSS framework which aims at bringing concepts of material design while keeping the UI lightweight. The styles are highly customizable on two levels.
You can configure the base styles of all the components as well as modify each one of them individually. Elemental-UI is a high quality, modular set of UI scaffolding components and controls for React that are built from the outset to natively implement React patterns.
It features a "complete" set of beautiful UI components built with React, using Material Design principles. Take at look at this issueif you're interested.Have you ever wanted to create pure React form? Have you ever wished to use React with Material design? Imagine creating something functional and also beautiful! I have a great news for you … This is your lucky day! Today, in this tutorial, we will take React and Material design and create beautiful form.
I hope this tutorial will help you learn how to create simple UI such as form. I also hope it will give you a better understanding of React. Live demo on Codepen.
First, you should have at least basic knowledge of React. We discussed the basics of React in the previous tutorial on To-do app with React. Next great place for learning the fundamentals of React is React website. This website contains a lot of information with many examples to get you started.Elizabeth gilbert 談涵餚創感
Still, you will not be any smarter when you finish it. Therefore, I would suggest learning the fundamentals first. Anyway, this decision is up to you. There are a few more things you will need to work on this React form tutorial. You will need to use the React library. This library contains two parts. The first part is React itself. The second part is React DOM. Aside from React we will use three other external resources.When the data is handled by the components, all the data is stored in the component state.
You can control changes by adding event handlers in the onChange attribute:. Add an event handler in the onChange attribute, and let the event handler update the state object:.
Note: You must initialize the state in the constructor method before you can use it. Note: You get access to the field value by using the event. If you do not want to display the h1 element until the user has done any input, you can add an if statement. We create an empty variable, in this example we call it header. We add an if statement to insert content to the header variable if the user has done any input.
We insert the header variable in the output, using curly brackets. Add a submit button and an event handler in the onSubmit attribute:. Note that we use event.
You can control the values of more than one input field by adding a name attribute to each element. To access the fields in the event handler use the event. To update the state in the this. Note: We use the same event handler function for both input fields, we could write one event handler for each, but this gives us much cleaner code and is the preferred way in React.
You can validate form input when the user is typing or you can wait until the form gets submitted. Below you will see the same example as above, but the validation is done when the form gets submitted instead of when you write in the field.
Error messages in alert boxes can be annoying, so let's make an error message that is empty by default, but displays the error when the user inputs anything invalid:. In React, the selected value is defined with a value attribute on the select tag:. A simple select box, where the selected value "Volvo" is initialized in the constructor:.
If you want to report an error, or if you want to make a suggestion, do not hesitate to send us an e-mail:. Example: Add a form that allows users to enter their name: class MyForm extends React. Example: Add an event handler in the onChange attribute, and let the event handler update the state object: class MyForm extends React. Example: Display the header only if username is defined: class MyForm extends React. Example: Add a submit button and an event handler in the onSubmit attribute: class MyForm extends React.
Example: Write a form with two input fields: class MyForm extends React. Example: When you fill in your age, you will get an alert if the age field is not numeric: class MyForm extends React.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

May 8, May 11, Nov 19, Apr 3, May 13, HTML form elements work a little bit differently from other DOM elements in React, because form elements naturally keep some internal state.Humboldt kine farms
For example, this form in plain HTML accepts a single name:. This form has the default HTML form behavior of browsing to a new page when the user submits the form. If you want this behavior in React, it just works.
In React, mutable state is typically kept in the state property of components, and only updated with setState. Then the React component that renders a form also controls what happens in that form on subsequent user input.
For example, if we want to make the previous example log the name when it is submitted, we can write the form as a controlled component:. Try it on CodePen. Since the value attribute is set on our form element, the displayed value will always be this.
Since handleChange runs on every keystroke to update the React state, the displayed value will update as the user types. While this means you have to type a bit more code, you can now pass the value to other UI elements too, or reset it from other event handlers. Notice that this.
For example, this HTML creates a drop-down list of flavors:. Note that the Coconut option is initially selected, because of the selected attribute. React, instead of using this selected attribute, uses a value attribute on the root select tag. This is more convenient in a controlled component because you only need to update it in one place. For example:. You can pass an array into the value attribute, allowing you to select multiple options in a select tag:. Because its value is read-only, it is an uncontrolled component in React.
It is discussed together with other uncontrolled components later in the documentation. When you need to handle multiple controlled input elements, you can add a name attribute to each element and let the handler function choose what to do based on the value of event. Note how we used the ES6 computed property name syntax to update the state key corresponding to the given input name:. Also, since setState automatically merges a partial state into the current statewe only needed to call it with the changed parts.
Specifying the value prop on a controlled component prevents the user from changing the input unless you desire so. The following code demonstrates this. The input is locked at first but becomes editable after a short delay. It can sometimes be tedious to use controlled components, because you need to write an event handler for every way your data can change and pipe all of the input state through a React component. This can become particularly annoying when you are converting a preexisting codebase to React, or integrating a React application with a non-React library.
In these situations, you might want to check out uncontrolled componentsan alternative technique for implementing input forms. Edit this page. Main Concepts. Advanced Guides. API Reference. Concurrent Mode Experimental. Previous article.Drag & Drop Bootstrap Form Builder
Lifting State Up.A dynamic form is one where the user is able to decide how many inputs there should be. Each new cat will have a name and age, just for fun. You can code along with me, or just skip to the end and see the full code, and refer back to any parts that confuse you.
Planning is crucial with React, it can save you so much time if you wireframe out what you want before you start coding. We know what it will look like, but how will it be made? I like to have a little React checklist:. In this case, I feel like it would read nicely to have a main Form component, and then CatInputs components that we can just render as we go.
But our CatInputs components will not require state, since we can just pass everything in as props. Finally, there are 3 events: we need to handle the form getting submitted, we need to handle changes to each input, and we need to handle the button that adds new inputs. In general, I like to render whatever I need first, and then start working on the interactivity. Before we code, we should talk about how we are going to do this.
Each object will have a name and age value. Our Form will iterate over this list and create two new inputs for the name and age.Mooer pedals clone list
Since this will change our state, it will trigger a re-render. Then, our form will iterate over this new list of cats, it will add another pair of inputs.
You should always include labels to ensure your site is accessible and screenreader friendly. And that dataset will be crucial to controlling our inputs later, since it matches the inputs to the index of the corresponding cat object in the cats array. Since our form is creating two new inputs, we know that the iteration aspect is working. But for it to truly be dynamic, we have to be able to let the user add the inputs. We just need to give our component a method that adds a new blank cat to our array.
This will make our component re-render, and when it does, the form will iterate over the new length of the array, giving us another pair of inputs. Here is the method that will control changes in all our inputs, static and dynamic, and our final state:. These are called Computed Property Namescheck them out. So our owner input has a name of ownerwhich means our setState translates to owner: whatever-was-typed.
Now for the fancy part; handling our dynamic inputs. If it does, we make a copy of our cats array of objects using the spread operator. Now it gets real fancy. We use e. So, if a user types into the first cat name input this is what it would translate to:. Now that our copied list has been mutated to reflect the new input, we use setState to save the change to our state and trigger a re-render of our form.
That may take a second to get comfortable with, but by making our change handler dynamic, we can put it on the whole form instead of each input:.
Here is our finished code in one component. It has all the inputs controlled, and to prove it, it uppercases everything:. We now have a full, dynamic, controlled form. Now our Form looks like this:.
