javascript - Pull a single item from json and display in html -


i have array in json file , want pull single entry array , display when page loads. have gotten partway there using this question , answer, attempt adapt answer causes output html block repeat array items in sequence instead of picking one.

here screenshot of get: screenshot of output

i doing real stupid, , hope can point out. script follows:

    $.getjson('recommend.json', function(data) {     var entry = data[math.floor(math.random()*data.length)];  $.each(data, function(entryindex, entry) {         var html = '<div class="rec_img"><img src="./recs/' + entry['img'] + '" /></div>';      html += '<span class="rec_title">' + entry['title'] + '</span><p>';         html += '<span class="rec_author">' + entry['author'] + '</span><p>';         html += '<span class="rec_blurb">' + entry['blurb']  + '</span>';          $('#recblock').append(html).fadein();       });     });

any questions let me know.

cut this:

$.each(data, function(entryindex, entry) {

the whole purpose of $.each iterate on entire array, opposite of want. you're defining entry earlier random entry data.

so you'll have:

$.getjson('recommend.json', function(data) {     var entry = data[math.floor(math.random()*data.length)];      var html = '<div class="rec_img"><img src="./recs/' + entry['img'] + '" /></div>';      html += '<span class="rec_title">' + entry['title'] + '</span><p>';     html += '<span class="rec_author">' + entry['author'] + '</span><p>';     html += '<span class="rec_blurb">' + entry['blurb']  + '</span>';      $('#recblock').append(html).fadein(); });
