Find Verbose IDs in the DOM

Published in: JavaScript 

Traverses the DOM tree and reports if any IDs are over 30 characters in length. Doesn't check for doubled IDs because that's caught when validationg the HTML.

Plain TextExpand 
  1. var allTags = document.body.getElementsByTagName('*');
  2. var ids = [];
  3. var longId = 0;
  4. for (var tg = 0; tg< allTags.length; tg++) {
  5.     var tag = allTags[tg];
  6.     if (tag.id) {
  7.             ids.push(tag.id);
  8.             if (tag.id.length > 30) longId++;
  9.      }   
  10. }
  11. alert(longId + " out of " + ids.length + " IDs are too long.")
