  $('#display').click(function () {         var vacancyid = $("#vacancy").val();         var model = {             vacancyid: vacancyid     };          $.ajax({     url: '@url.action("questionblocks", "questions")',     contenttype: 'application/json; charset=utf-8',     data: json.stringify(model),     type: 'post',     datatype: 'json',     processdata: false,     success: function (data) {         var question1 = data[0]          $(".list").append('<div style="width:80%;font-size:20px;margin-top:15px;border-style: solid;border-color:#ffcf00;border-radius: 5px;margin: 10px auto 0;;">' + question1.question1 + '</div>' + '<div style="width:80%;font-size:20px;margin-top:15px;border-style: solid;border-color: #ffcf00;border-radius: 5px;margin: 10px auto 0;">' + question1.question2 + '</div>' + '<div style="width:80%;font-size:20px;margin-top:15px;border-style: solid;border-color: #ffcf00;border-radius: 5px;margin: 10px auto 0;">' + question1.question3 + '</div>' + '<div style="width:80%;font-size:20px;margin-top:15px;border-style: solid;border-color: #ffcf00;border-radius: 5px;margin: 10px auto 0;">' + question1.question4 + '</div>' + '<div style="width:80%;font-size:20px;margin-top:15px;border-style: solid;border-color: #ffcf00;border-radius: 5px;margin: 10px auto 0;">' + question1.question5 + '</div>' + '<div style="width:80%;font-size:20px;margin-top:15px;border-style: solid;border-color: #ffcf00;border-radius: 5px;margin: 10px auto 0;">' + question1.question6 + '</div>' + '<div style="width:80%;font-size:20px;margin-top:15px;border-style: solid;border-color: #ffcf00;border-radius: 5px;margin: 10px auto 0;">' + question1.question7 + '</div>' + '<div style="width:80%;font-size:20px;margin-top:15px;border-style: solid;border-color: #ffcf00;border-radius: 5px;margin: 10px auto 0;">' + question1.question8 + '</div>' + '<div style="width:80%;font-size:20px;margin-top:15px;border-style: solid;border-color: #ffcf00;border-radius: 5px;margin: 10px auto 0;">' + question1.question9 + '</div>' + '<div style="width:80%;font-size:20px;margin-top:15px;border-style: solid;border-color: #ffcf00;border-radius: 5px;margin: 10px auto 0;">' + question1.question10 + '</div>');         $(".list").find('div.section:empty').hide();          }     }); });

but divs empty because values back-end null.

i need hide empty divs

i try $(".list").find('div.section:empty').hide(); seems not works.

what wrote wrong in code?

this can done using javascript only. in approach, div's, check if empty , hide them accordingly. 

var req = document.getelementsbyclassname('list'); for(j=0; j<req.length; j++) {     var divs = req[j].innerhtml.getelementsbytagname('div');// got divs in current element      for(i=0; i<divs.length; i++)     {         if(divs[i].innerhtml == "")         {         divs[i].style.display = 'none';         }     } }

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
