Troubleshooting user input for API scraping program












0















This program is supposed to output lyrics from a given API. This works when the song and artist are manually set at variables before pressing the submit button. However, I realize that it cannot work when taking user input for song because the JSON load is inside setup, which is loaded before the input is even given. How would I go about fixing this? I already tried to create another function for loadJSON, but it still was not working.



The expected output should be when you press submit, the user's song (I will deal with artist input later) lyrics should be produced. Thank you!



var search, button, question, input;

var artist = 'One%20Direction/';

var song = 'Taken';

var url_root = 'http://lyric-api.herokuapp.com/api/find/'



function setup() {

  noCanvas();



  input = createInput ();

  input.position (20, 50);



  button = createButton ("Submit");

  button.position(input.x + input.width, 50);

  button.mousePressed(goSearch);



  var url = url_root + artist + song;

  loadJSON (url, gotData);



  question = createElement ('h2', 'Search a song:');

  question.position(20, 5);



}



function gotData(data) {

  search = data;

}



function goSearch() {

    var thing = search.lyric

    var result = createP(thing);

    result.position (20, 60);

}

I believe the following provides what you're after. In summary:




  • Addition of input.value() to get user's input value

  • Minor refactoring of functions





var search, button, question, input;

var artist = 'One%20Direction/';

var url_root = 'http://lyric-api.herokuapp.com/api/find/'



// Page setup

function setup() {

  noCanvas();



  input = createInput ();

  input.position (20, 50);



  button = createButton ("Submit");

  button.position(input.x + input.width, 50);

  button.mousePressed(goSearch);



  question = createElement ('h2', 'Search a song:');

  question.position(20, 5);

}



// When data is returned, lets display it

function gotData(data) {

  search = data;

  var thing = search.lyric

  var result = createP(thing);

  result.position (20, 60);

}



// Perform request when user submits search term

function goSearch() {

  var song = input.value(); // Get the form field's input value

  var url = url_root + artist + song;

  loadJSON (url, gotData);

}

            Monofisismo

            Image
            Monofisismo (do grego: monos - "único, singular" e physis - "natureza") é o ponto de vista cristológico que defende que, depois da união do divino e do humano na encarnação histórica, Jesus Cristo, como encarnação do Filho ou Verbo ( Logos ) de Deus, teria apenas uma única "natureza", a divina, e não uma síntese de ambas. O monofisismo é contraposto pelo diofisismo (ou "diafisismo"), que defende que Jesus preservou em si as duas naturezas. Historicamente, o monofisismo se refere primordialmente à posição dos que (especialmente no Egito e, em menor grau, na Síria) rejeitaram as decisões do Concílio de Calcedônia em 451 (o quarto concílio ecumênico). Os membros mais moderados entre eles, porém, defendem a teologia "miafisita", que se tornou a oficial para as Igrejas Ortodoxas Orientais.

            Olmecas

            Monumento 1, uma das quatro cabeças colossais encontradas em La Venta, com altura aproximada de 3 metros Olmecas é a designação do povo e da civilização que estiveram na origem da antiga cultura pré-colombiana da Mesoamérica e que se desenvolveram nas regiões tropicais do centro-sul do atual México durante o pré-clássico, próximo de onde hoje estão localizados os estados mexicanos de Veracruz e Tabasco, no Istmo de Tehuantepec, numa zona designada área nuclear olmeca. A cultura olmeca floresceu nesta região aproximadamente entre 1500 e 400 a.C., [ 1 ] e crê-se que tenha sido a civilização-mãe de todas as civilizações mesoamericanas que se desenvolveram posteriormente. [ 2 ] No entanto, desconhece-se a sua exacta filiação étnica, ainda que existam numerosas hipóteses colocadas para tentar resolver esta questão. O etnónimo olmeca foi cunhado pelos arqueólogos do século XX, e não devem confundir-se com os muito posteriores olmecas-xicalancas que ocuparam vários locais do México...
