Question

I need to parse this json with javascript

    {
     "MasterProducts": {
    "MasterProduct": [
      {
        "Productcode": "0903-000192",
        "Description": "ICROCOMPUTER;32FX200 24BIT QFP 132P",
        "ThumbPic": "NoImage.png",
        "RRP": "41.400000",
        "Stock": "0"
      },
      {
        "Productcode": "0160-030",
        "Description": "AXIS MPEG-4 Decoder 50-user licence pack onto 50 separate computers. For all Axis MPEG-4 products that do not support AAC audio encoding. (210 211 210A 211A 213 214 221 225FD 231D+ 232D+ 241S 241Q 241SA 241QA 242SIV 243SA 282 282A).",
        "ThumbPic": "NoImage.png",
        "RRP": "35.230000",
        "Stock": "0"
      },
      {
        "Productcode": "0160-040",
        "Description": "AXIS MPEG-4 +ACC Decoder 50-user license onto 50 separate computers. For all Axis products that supports MPEG-4. (207 207W 207MW 212PTZ 216FD 223M).",
        "ThumbPic": "NoImage.png",
        "RRP": "50.880000",
        "Stock": "0"
      },
      {
        "Productcode": "10403E",
        "Description": "Hotsync palm computer cradle/docking station",
        "ThumbPic": "NoImage.png",
        "RRP": "0.000000",
        "Stock": "2"
      },
      {
        "Productcode": "0903-000193",
        "Description": "ICROCOMPUTER;32FX200 24BIT QFP 132P",
        "ThumbPic": "NoImage.png",
        "RRP": "37.790000",
        "Stock": "0"
      }
    ]
  }
}

I have managed to do it when it’s only one result with this code

 if(data !== '')
    {
        xmlData = data.childNodes[0].childNodes[0].data;
        objData = app.XML2OBJ(xmlData);            
        var item = objData.MasterProduct.Description;
        //alert(item);
    }

But can’t get it to work with multiple sets of results.

Answer 1

As people have been discussing in the comments above, you can simply use normal vanilla JavaScript to access the data.

var data = // JSON 

console.log(data.MasterProducts.MasterProduct[0].Productcode);

Will give you 0903-000192. Objects that contain square brackets [] are arrays. For them you can use the array notation of arr[0]. For objects, you can use their key names.

{
"MasterProducts": {
 "MasterProduct": [
   {
     "Productcode": "0903-000192",
     "Description": "ICROCOMPUTER;32FX200 24BIT QFP 132P",
     "ThumbPic": "NoImage.png",
     "RRP": "41.400000",
     "Stock": "0"
   }
 ]
}

MasterProducts is your root object, so you can use it as your entry point.

var products = data.MasterProducts;

Now, to get the first element of the list of products you could use array notation.

products.MasterProduct[0]

To get at one of the properties of that element, you could then again use the dot notation –

products.MasterProduct[0].Description //"ICROCOMPUTER;32FX200 24BIT QFP 132P"
