JQuery.html () and the variable inside

Question

I would like to put the FLC variable inside $("#FNC").html(''); but don’t know how, what are the 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 the FLV value in 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" />'); 

Answer 2

String concatenation is dangerous without input validation.

Just use .val() to set the input value, and ideally use the jQuery constructor rather than .html() to create it:

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