Questions about finding JustValidate
How does PageSourceSearch know a website uses JustValidate?
By the source itself: The site's code creates the validator with new JustValidate(form). PageSourceSearch stores the raw HTML and first-party JavaScript of each crawled site and matches the keyword byte for byte, so every listed site's stored source contains it.
Is this a complete list of websites using JustValidate?
No. The page lists the 50 highest-ranked sites in the index whose source holds the keyword, out of about 1,108 websites that do; the count is the index's estimate at the time the list was computed. Run the keyword as a search to page through all of them, or add a kind or date filter.
How do I find websites that use JustValidate together with another technology?
Search for both keywords at once: several terms separated by spaces must all be found on the same site, or with the Same page toggle in the same page. For example JustValidate( with wp-content/plugins/ lists the WordPress sites that use JustValidate.
