You need to use data['0_256']:

var data = {
    '0_0': {
          file: "xy.jpg",
          height: 256,
          width: 256
     },
    '0_256': {
          file: "xx.jpg",
          height: 256,
          width: 256
    }
};
console.log(data['0_256']);

you can try "data['0_256']"

`console.log(data['0_256'])`

var   data = { 
        "0_0" :{
            file: "xy.jpg",
            height: 256,
            width: 256
            },
        "0_256":{
            file: "xx.jpg",
            height: 256,
            width: 256
            }
          }
console.log(data['0_256']);
