Recursively find string in DOM

find.js

function find(object, search, cache, path) {
  if (!cache)
    cache = [];
  if (!path)
    path = '';
  if (cache.indexOf(object) >= 0)
    return;
  cache.push(object);

  for (var key in object) {
    if (object.hasOwnProperty && !object.hasOwnProperty(key))
      continue;

    var found = key.indexOf(search) >= 0;
    var value;
    try {
      value = object[key];
    } catch (e) {}

    found |= value && value.indexOf && value.indexOf(search) >= 0;

    if (found) {
      console.log(path);
      console.log(object);
    }

    if (value instanceof Object)
      find(value, search, cache, path + '.' + key);
