you need use loop iterate on items received in order form list of items added dom. create bulk of new dom elements prefer collect them in string buffer , add @ once - bit more faster, not necessary. code may this:

javascript

function getsimilar() {     $.ajax({         type: "get",         url: "../content/test.txt",         datatype: "json",         success: function (data) {           var i, l, list;           if(data && data.length > 0) {             list = ['<ul>'];             for(i=0,l=data.length; i<l; i++) {               list.push('<li data-id="' + data[i].id + '">' + data[i].title + '</li>');             }             list.push('</ul>');             $('#similar').html(list.join(''));           }         },         error: function (data) {             console.error('error in ajax call');             console.error(data);         }     }); }
