Jinsi ya Kutengeneza Client-Side Form Wizard kwa JavaScript

Client-Side Form Wizard inawawezesha watumiaji kujaza fomu ndefu hatua kwa hatua, huku data ikihifadhiwa kwenye browser kabla ya ku-submit. Hii inaboresha user experience na kupunguza errors kwenye forms kubwa.

Hatua kwa Hatua
1️⃣ Unda HTML Form Wizard

2️⃣ JavaScript kwa Form Wizard
const steps = document.querySelectorAll(".step");
let currentStep = 0;

function showStep(index) {
steps.forEach((step, i) => step.style.display = i === index ? "block" : "none");
}

document.getElementById("next1").addEventListener("click", () => {
currentStep = 1;
showStep(currentStep);
});

document.getElementById("prev2").addEventListener("click", () => {
currentStep = 0;
showStep(currentStep);
});

document.getElementById("next2").addEventListener("click", () => {
currentStep = 2;
showStep(currentStep);
});

document.getElementById("prev3").addEventListener("click", () => {
currentStep = 1;
showStep(currentStep);
});

// Optional: Save data to LocalStorage for auto-save
const form = document.getElementById("wizardForm");
form.addEventListener("input", (e) => {
localStorage.setItem(e.target.name, e.target.value);
});

// Load saved data
window.addEventListener("DOMContentLoaded", () => {
const inputs = form.querySelectorAll("input, textarea");
inputs.forEach(input => {
const saved = localStorage.getItem(input.name);
if (saved) input.value = saved;
});
});

// Handle submit
form.addEventListener("submit", (e) => {
e.preventDefault();
alert("Fomu imewasilishwa!");
localStorage.clear();
form.reset();
});
