Filtering JSON data

Question

I have a JSON file which contains data like the following:

{\"posts\": [ 
    { \"title\":\"1\", \"url\":\"n1.png\" }, 
    { \"title\":\"2\", \"url\":\"n2.p         


        

Answer 1

Why not do this?

var json = JSON.parse('{"posts": [ 
{ "title":"1", "url":"n1.png" }, 
{ "title":"2", "url":"n2.png" }, 
{ "title":"3", "url":"n3.png" }, 
{ "title":"4", "url":"n4.png" }, 
{ "title":"5", "url":"n5.png" }, 
{ "title":"6", "url":"n6.png" }, 
{ "title":"7", "url":"n7.png" }, 
{ "title":"8", "url":"n8.png" }, 
{ "title":"9", "url":"n9.png" }, 
{ "title":"10", "url":"n10.png" }
]}');

var filteredJson = json.posts.filter(function (row) {
  if(row.title matches your criteria) {
    return true
  } else {
    return false;
  }
});

Yes, its an ES5 method but that can be shimmed quite nicely
