While learning about HTML Grouping by IDs and Classes, found this chrome extension. Really, I liked the way it displayed the results.
It works good and fast. But fails to ignore the content of the <script> tags; their content is supposed to be just text ("text/javascript", "text/template", etc.) and not be parsed as HTML/DOM in any way.
Simple but very effective. Great tool to find duplicate (and not only) ids on a page.
Seemed to work great on first use, got all my IDs and found no duplicates.
Great Tool, Duplicate HTML ids are the devil!
When I concentrate on the features of my web-application too much, I tend to forget my HTML syntax. This plugin is really easy to use.
