How to access the data of an object?

  • 772

I have tried to access the title value inside the query, I am using the Wikipedia API, I have tried with:

query[search]
//También con
var obj = JSON.parse(query);
var nombre = obj['search'];

enter image description here

Request source code with jquery

$(".searchBox").on("change", function() {
        var searchTerm = $("#searchTerm").val();
        var url = "https://es.wikipedia.org/w/api.php?action=query&list=search&srprop=snippet&format=json&origin=*&utf8=&srsearch=" + searchTerm;
        $.ajax({
            url: url,
            type: 'GET',
            contentType: "application/json; charset=utf-8",
            async: false,
            dataType: "json",
            success: function(data, status, jqXHR) {
                console.log(data);
                //no funciona

    You receive the API response through the variable dataso you can access the json structure as follows, data.query.searchwhich is the part of interest; from here there is an arrangement, which you can continue processing

    $(".searchBox").on("change", function() {
    var searchTerm = $("#searchTerm").val();
    var url = "https://es.wikipedia.org/w/api.php?action=query&list=search&srprop=snippet&format=json&origin=*&utf8=&srsearch=" + searchTerm;
    $.ajax({
        url: url,
        type: 'GET',
        contentType: "application/json; charset=utf-8",
        async: false,
        dataType: "json",
        success: function(data, status, jqXHR) {
            var search = data.query.search;
        }
    })
});

  2. You have to verify the structure of the object, according to the image it has the following structure:

    query:{
  searchinfo:{}, //Objeto
  search:[{}] //Arreglo de Objetos
}

    Therefore, to access the data you require, you should do it as follows:

    query.search[0].title
