Answer 1

Break your append part in variables and then concate it. may be that can help ?

 $(document).ready(function() {
 $.getJSON( "js/appjson.json", function(data) {
 for (var i = 0; i < data.length; i++) {
       var content_append = "normal content";
        if(data[i])
        {
          content_append = "content here with data[i]"
        }

          $('#jsonLoad').append(content_append);
       }
     });

});

'<div>' + 
(something === something_else)? 'some data1' : 'some data2' +
'</div>'
