Search in Json file and get results using Javascript

Question

I'm developing an dictionary app for FirefoxOS by Javascript . my json file look like this

[
{"id":"3784","word":"Ajar","type":"adv.","descr":" Slightly turned or opened; as, the door was standing ajar.","track":"a","track_2":"Aj","track_3":"Aja"},
{"id":"3785","word":"Ajar","type":"adv.","descr":" In a state of discord; out of harmony; as, he is ajar with the world.","track":"a","track_2":"Aj","track_3":"Aja"},{"id":"3786","word":"Ajog","type":"adv.","descr":" On the jog.","track":"a","track_2":"Aj","track_3":"Ajo"},
{"id":"3787","word":"Ajutage","type":"n.","descr":" A tube through which water is discharged; an efflux tube; as, the ajutage of a fountain.","track":"a","track_2":"Aj","track_3":"Aju"}                               ]

Now I want to query this json file where word = "aj" and get the all the matched results or id's of the matched results . How can I do that ?

TRY THIS UPDATED FIDDLE DEMO

var jsonArrr =[
{"id":"3784","word":"Ajar","type":"adv.","descr":" Slightly turned or opened; as, the door was standing ajar.","track":"a","track_2":"Aj","track_3":"Aja"},
{"id":"3785","word":"Ajar","type":"adv.","descr":" In a state of discord; out of harmony; as, he is ajar with the world.","track":"a","track_2":"Aj","track_3":"Aja"},{"id":"3786","word":"Ajog","type":"adv.","descr":" On the jog.","track":"a","track_2":"Aj","track_3":"Ajo"},
{"id":"3787","word":"Ajutage","type":"n.","descr":" A tube through which water is discharged; an efflux tube; as, the ajutage of a fountain.","track":"a","track_2":"Aj","track_3":"Aju"}                               ];

var matchMe = new RegExp('^' + 'aj', 'i');
    var matches = [];
        for (var i in jsonArrr) {
            if (jsonArrr[i].word.search(matchMe) > -1 ) {

                    matches.push( {'id': i, 'word': jsonArrr[i].word} );

            }
        }

To see the result

 for (var i in matches) { 
                console.log(matches[i].word);
                //your code
                }

Take console window in Inspect Element to see the result

Answer 2

var matchedIndexes = []
for (var i=0; i < array.length; i++) {
    var obj = array[i];
    if (obj.hasOwnProperty("word")) {
        if(obj["word"].match(/aj/i)) {
            console.log("matched");
            matchedIndexes.push(i);     
        }
    }
}

matchedIndexes will contain all indexes in which object has word "aj" ( case insensitive ). array in this code is your object of arrays.

Answer 3

Loop through the json array :

var result = null;
    Objects.forEach(function(obj, i){
        if(obj.word == 'aj'){
            return result = obj;
        }
    });
    console.log(result);
