Question

I’m trying to parse JSON in JavaScript. If my JSON data looks like below, I want to iterate through all the JSON elements that start with “custom” and not with any other string. How do I do this?

{
    "fields": {
        "custom12": {
            value: "dsada"
        },
        "custom45": {
            value: "adsadad"
        },
        "test12": {
            value: "12323"
        }
    }
}​

Answer 1

var newObject = {}, key;
for(key in data.fields){
  if(key.search(/custom/) > -1){
    newObject[key] = data.fields[key];
  }
}
console.log(newObject);
