javascript - recursively find a specific key or value in any sub object (quick hack)

searchObj.js

var seen = [];
var results = [];

function searchObj (obj, query, strparent, level) {
    level = level || 1;
    if (level % 3==0 || level==1)
        console.info(level);
    for (var key in obj) {
        var orig_sig = strparent + "." + key;
        var sig = orig_sig.split(".").slice(-2).join(".");

        if (seen.indexOf(sig) >=0){
            //console.log("skipping (seen): "+sig);
            return;
        }else if (orig_sig.indexOf("next")>=0 || orig_sig.indexOf("parent")>=0 || orig_sig.indexOf("child")>=0 || orig_sig.indexOf("sibli")>=0){
            return;
        }
        try{
          var value = obj[key];
          if (typeof value === 'object') {
              searchObj(value, query, orig_sig, level+1);
          }
          if (value === query || key === query) {
              console.warn(orig_sig + '  property=' + key + ' value=' + value);
              results.push(orig_sig + "="+ value);
          }
       } catch(e) {}
       seen.push(sig)
    }
    return;
}
