React JS form validation

Introduction:

Form validation in React JS & Native Course ensures that the user inputs correct and complete information in your forms before submitting them. Here’s a simple guide to help you understand how to add validation to your forms in React.

Why Validate Forms?

Validating forms helps you:

Ensure the user inputs the required information.

Prevent incorrect or incomplete data submission.

Improve the user experience by guiding users on how to fill out the form correctly.

Setting Up Your Form

Let's create a basic form with fields for name and email. We will also add simple validation to check if these fields are filled out correctly.

Create the Form Component

First, create a new component for your form:

// Form.js import React, { useState } from 'react';

function Form() { const [name, setName] = useState(''); const [email, setEmail] = useState(''); const [errors, setErrors] = useState({});

const validate = () => { let formErrors = {}; if (!name) formErrors.name = "Name is required"; if (!email) formErrors.email = "Email is required"; else if (!/\S+@\S+.\S+/.test(email)) formErrors.email = "Email is invalid"; return formErrors; };

const handleSubmit = (e) => { e.preventDefault(); const formErrors = validate(); if (Object.keys(formErrors).length === 0) { console.log("Form submitted successfully!"); // Process form data here } else { setErrors(formErrors); } };

return ( Name:

setName(e.target.value)} /> {errors.name &&

{errors.name}} Email:

setEmail(e.target.value)} /> {errors.email &&

{errors.email}} Submit ); }

export default Form;

How It Works

State Management: We use useState to manage the state of the form inputs (name and email) and any validation errors.

Validation Function: The validate function checks if the fields are filled out and if the email is in the correct format.

Handle Submit: The handleSubmit function is called when the form is submitted. It prevents the default form submission, validates the inputs, and sets errors if there are any.

Displaying Errors: If there are validation errors, they are displayed below the respective input fields.

Adding More Validations:

You can add more validation rules as needed. For example, to check if the name is at least 3 characters long:

if (name.length < 3) formErrors.name = "Name must be at least 3 characters long";

To check if the email is in the correct format:

if (!/\S+@\S+.\S+/.test(email)) formErrors.email = "Email is invalid";

Summary:

Form validation in React JS helps ensure users fill out forms correctly before submitting. By using state to manage input values and validation errors, you can guide users to enter the right information. This simple setup can be expanded with more complex validation rules as needed.

Start adding validation to your React forms to improve data accuracy and user experience!

Today my therapist introduced me to a concept surrounding disability that she called "hLep".

[plain-text version of this post can be found under the cut]

Which is when you - in this case, you are a disabled person - ask someone for help ("I can't drink almond milk so can you get me some whole milk?", or "Please call Donna and ask her to pick up the car for me."), and they say yes, and then they do something that is not what you asked for but is what they think you should have asked for ("I know you said you wanted whole, but I got you skim milk because it's better for you!", "I didn't want to ruin Donna's day by asking her that, so I spent your money on an expensive towing service!") And then if you get annoyed at them for ignoring what you actually asked for - and often it has already happened repeatedly - they get angry because they "were just helping you! You should be grateful!!"

And my therapist pointed out that this is not "help", it's "hLep".

Sure, it looks like help; it kind of sounds like help too; and if it was adjusted just a little bit, it could be help. But it's not help. It's hLep.

At its best, it is patronizing and makes a person feel unvalued and un-listened-to. Always, it reinforces the false idea that disabled people can't be trusted with our own care. And at its worst, it results in disabled people losing our freedom and control over our lives, and also being unable to actually access what we need to survive.

So please, when a disabled person asks you for help on something, don't be a hLeper, be a helper! In other words: they know better than you what they need, and the best way you can honor the trust they've put in you is to believe that!

Also, I want to be very clear that the "getting angry at a disabled person's attempts to point out harmful behavior" part of this makes the whole thing WAY worse. Like it'd be one thing if my roommate bought me some passive-aggressive skim milk, but then they heard what I had to say, and they apologized and did better in the future - our relationship could bounce back from that. But it is very much another thing to have a crying shouting match with someone who is furious at you for saying something they did was ableist. Like, Christ, Jessica, remind me to never ask for your support ever again! You make me feel like if I asked you to call 911, you'd order a pizza because you know I'll feel better once I eat something!!

Edit: crediting my therapist by name with her permission - this term was coined by Nahime Aguirre Mtanous!

Edit again: I made an optional follow-up to this post after seeing the responses. Might help somebody. CW for me frankly talking about how dangerous hLep really is.

"Well, this is a bad idea," Tim says, hands on his hips as he surveys the mess they’ve made in the cave.

"Nah," Danny replies, twirling his screwdriver in the air in what is probably meant to be an impressive trick to inspire confidence, except he fumbles it and it clangs to the floor loudly, "we good. If a younger version of myself hasn't come forward in time to stop me, how bad can it be?"

"Shouldn't it be the other way round?"

"What?"

"Normally, it's an older version of yourself going backwards in time to stop you, right?"

"Not in my experience."

Danny's grin is impossibly feral and a shiver runs up Tim's spine.

"This is definitely a bad idea."

I'm so tired of the "English is a dumb bad language because it has no rules" take. It actually has quite a lot of rules, all of which make sense. You're just so lazy that you think the fact that not every function is uniform means that you shouldn't bother. It could be worse, you know. You could be dealing with agglutination. How does a three-line sentence that's only a single word sound to you? What about having to remember seven different words for "the"? We don't even have grammatical gender (which has nothing to do with human sex, like at all. Go check Irish's list of feminine and masculine words and prepare to be very confused). No declensions, barely any grammatical cases, no tones, no formal registers, and you're out here complaining that English is too hard because you keep forgetting that the past tense of "break" isn't "breaked". Sorry for that, but that's on you, not the language.

When do I get a turn at being cum and cock drunk, mindlessly saying ‘thank you’ for getting throatfucked and slapped in the face with your cock because it’s the polite thing to do.

chat if this post gets found I might get backlash but jean moreau has always been bisexual. TSC SPOILERS

like this is a personal opinion but almost a third of his own book is him liking renee. I see so many people saying that "he's gay" or "he always knew he was gay" and like I get it! headcanons can exist! however I counter this by saying that saying jean (who is not confirmed but HEAVILY implied to be bisexual) is very similar to saying that andrew is bi or pan when he is not! jean moreau likes both guys and girls-a notion that is very obvious in a series with very little bi rep-and saying that he like, came out of the womb gay is simply not true.
