Are there any jquery features to query multi-dimensional arrays in a similar fashion to the DOM?

Question

What the question says...

Does jQuery have any methods that will allow you to query a mult-dimensional array of objects in a similar fashion as it does with the DOM.

Answer 1

I just wrote this.. I think it works properly but it could definitely get cleaned up :)

function findMatchingObjects(obj, member, value){
   var final = new Array();
   var temp = new Array();
   for(var p in obj){
    if (typeof obj[p] == 'object' ) {
     temp = findMatchingObjects(obj[p], member, value);
     if (temp.length == 1)
      final.push(temp[0]);
    }
    if (p == member && obj[p] == value) {
     final.push(obj);
    }
   }
   alert(final.length);
   return final;
}

Use it like so:

var moo ={baz: 1, boo: 2, bar:{c1: 3, c2: 4, c3:{t:true, f:false, baz:1}},d: 11};
var foo = findMatchingObjects(moo, "baz", 1);

// did it work?
console.log(foo);

Returns an array of object (or sub-objects) that match the member-value pair. In this case, foo contains both moo and c3 since both of the objects contain a baz = 1 pair.

Making the function look and feel like a jQuery selector is just a matter of syntactic sugar.
