Building a browser‑only website launch checklist with accessible HTML and localStorage

说明与用途

一个完全在浏览器中运行的单页网站启动检查表，使用原生控件、可访问性功能和 localStorage 来持久化状态，无需后端。

问题

Website launch checklists are usually PDFs or documents, which become problematic when multiple people need to work through one, the tab closes, or the checklist needs to be reused without sending data to another service.

结果

The checklist runs entirely in the browser, preserves state across reloads, supports printing, and requires no server or analytics, making it suitable for personal or small‑team use.

工作流

• Create a single HTML file with native checkbox inputs wrapped in labels for accessibility.
• Add a native <progress> element to display completion percentage.
• Use JavaScript to update the progress value and accessible label on each checkbox change.
• Store checked checkbox IDs in localStorage under a unique key.
• On page load, read localStorage and restore checked states.
• Provide a reset button that clears only the checklist’s storage key.
• Add a print stylesheet to format the checklist for printing and a print button that calls window.print().

证据

Website launch checklists are usually PDFs or documents. That is fine until several people need to work through one, the tab closes, or the checklist needs to be reused without sending data to another service.

I built a small open‑source version that runs entirely in the browser: https://bryceelliot.github.io/website-launch-checklist/

The JavaScript updates both the numeric value and an accessible label. A screen‑reader user gets the same progress information as a sighted user.

Checked item IDs are saved to localStorage in the visitor’s browser.

The reset control clears only this checklist’s storage key and returns focus to the first item. It does not erase unrelated browser storage.
