Question

I would like to put variable FLC in inside $("#FNC").html(''); but don’t know how to, any tips?

DEMO:

var FLV = $("#random-input-box").val();
$("#FNC").html('<input id="random-input-box" style="width: 99px;" value="FLC" disabled="disabled" />');

Answer 1

Did you mean putting the value of FLV into the value attribute of the input field?

var FLV = $("#random-input-box").val();
$("#FNC").html('<input id="random-input-box" style="width: 99px;" value="'+FLV+'" disabled="disabled" />');
