javascript - Jquery add using append and remove using .remove -


i'm trying make 2 buttons acts remove , add function first have this:

html

<video id="localvideo" style="background-color:black"></video> <div id="remotevideos"></div>

buttons

<button id="btnon">on</button> <button id="btnoff">off</button>

script:

$(document).ready(function() {              //$("#btnon").click(function() {              //   $('#a').append("<div id='localvideo'>");              //   $('#a').append("<div id='remotevideos'>");                     //});              $("#btnoff").click(function() {                 $("#localvideo").remove();         $("#remotevideos").remove();         });                 });

what i'm trying remove 2 div's , have ability return them, condition can add them if missing , remove them if present, therefore limiting them 1 add , 1 remove. how can accomplish this?any suggestion appreciated

you check if #localvideo element exists. also, if elements in #a element, can remove them calling $('#a').empty();.

$(document).ready(function() {     $('#btnon').click(function() {         if ($('#localvideo').length == 0) {             $('#a').append('<video id="localvideo" style="background-color:black"></video><div id="remotevideos"></div>');         }     });      $('#btnoff').click(function() {         if ($('#localvideo').length > 0) {             $("#localvideo").remove();             $("#remotevideos").remove();         }     });     });

you consider hiding , showing video elements, rather adding , removing them.
