[removed] How can I get all the keys and values of an object that begin with a specific string?

Question

I am trying to get all the keys and values of an object that begin with imageIds.

My object appears as the following:

{
    title: \'fsd         


        

Answer 1

 // json to be searched
var data = {
    title: 'fsdfsd',
    titleZh: 'fsdfsd',
    body: 'fsdf',
    bodyZh: 'sdfsdf',
    imageIds: '/uploads/tmp/image-3.png',
    imageIdsZh: '' 
};


// takes the json 'data' as its 1st parameter
// and the desired 'property' to be searched as the 2nd parameter
// for loop iterates through the entire json
// if the property parameter matches a 'key' name in json e.g. 'imageIds'
// then the value for that property is returned
function fetchProperty (data, property) {
    for(var key in data) {
        if(key === property) {
            return data[key];
        }   
    }
}


// if you wanted to return a bunch of data according to a particular key - value pair
// you could do something like this...
// assume 'array' contains a bunch of jsons 
// newData will hold jsons containing your newly fetched data points
function fetchNewData() {
   var newData = [];
   for(var i = 0; i < array.length; i++) {

      var value1 = fetchProperty(array[i], 'imageIds');
      var value2 = fetchProperty(array[i], 'imageIdsZh');
      var value3 = fetchProperty(array[i], 'imageIdsBlah');

      var tempJSON = {};
      tempJSON.imageIds = value1;
      tempJSON.imageIdsZh = value2;
      tempJSON.imageIdsBlah = value3;

      newData.push(tempJSON);
   }
   return newData;
}
