Question

Friends I have following like json array

[
   {
      "Rate":100.0,
      "MaterialID":"BOLT",
      "BrandName":"",
      "Description":"",
      "Unit":"KG",
      "TokenNumber":2
   },
   {
      "Rate":null,
      "MaterialID":"PLYWOOD",
      "BrandName":"",
      "Description":"",
      "Unit":"FT",
      "TokenNumber":2
   },
   {
      "Rate":null,
      "MaterialID":"SCREW 1.5 INCH",
      "BrandName":"",
      "Description":"",
      "Unit":"KG",
      "TokenNumber":2
   }
]

I want to know the shortest way to find an element that has materialID with value PLYWOOD.
I can do it using for loop. But I want to know some shortcut for this something like

var unit = jsonArray[<whiere materialID == 'PLYWOOD']['Unit'];

You can use jQuery if required.
