Dynamic Search bar not working

Technical Q&A
,

Topic summary

A user created a new page listing Magic: The Gathering expansions with a dynamic search bar that worked in W3Schools but failed when implemented in Shopify.

Initial Problem:

  • Search functionality worked in testing environment but broke after adding to Shopify page
  • Issue likely related to how Shopify’s Liquid templates handle custom JavaScript

Suggested Solutions:

  • Ensure code (HTML, CSS, JS) is fully embedded in Shopify’s page HTML editor
  • Wrap JavaScript in document.addEventListener('DOMContentLoaded', function() { ... }) to ensure proper loading
  • Test with basic Shopify theme (like Dawn) to rule out theme conflicts
  • Alternative: Use Shopify’s native search tools with tagged collections

Resolution:
The issue was resolved by switching from vanilla JavaScript to jQuery for the search functionality.

Hello first of all thank you all!

I just added a new page to my website: https://mundodelcomic.com/pages/magic-the-gathering-set-site it will list all expansions for MTG, and I added a search function that it seems to work on w3schools editor, but when I added it to shopify page the dynamic search bar did not work.

Hope you guys can help me out!

Hey there! Thanks for sharing your new page. I love that you’re building a handy MTG expansions list for your community! It’s awesome to see the effort you’ve put in, but I get how frustrating it must be that the dynamic search bar isn’t working in Shopify after testing fine on W3Schools. Since Shopify’s liquid templates can sometimes mess with custom JavaScript, double-check that your search code (HTML, CSS, and JS) is fully embedded in the page—either by pasting it directly into the page’s HTML editor in Shopify (Content > Pages > Edit) or using a custom liquid section. If it’s still not firing, it might be a conflict with Shopify’s theme scripts—try wrapping your JS in a document.addEventListener(‘DOMContentLoaded’, function() { … }) to ensure it loads properly, or test it with a basic theme like Dawn to rule out interference. For a quick win, you could also lean into Shopify’s built-in search tools by tagging your MTG sets and linking them to a collection page instead

Fixed it by changing to jQuery instead of Javascript!
