javascript - Run code on window resize -


i'm trying run code when window resizing, code:

    $(document).ready(function () {             updatecontainer();             $(window).resize(function() {                 updatecontainer();             });              $('#slider').lightslider({                 item:1,                 slidemove:1,                 slidemargin: 30,                 loop: true,                 autowidth: slidewidth             });         });         function updatecontainer() {             var $winwidth = $(window).width();             if ($winwidth > 1100) {                  var slidewidth = false;                  /* toggle navigation                 ======================================================================== */                 $('.menu, .search, .categories').click(function(e) {                     $(this).toggleclass('active');                     e.preventdefault();                 });                   /* top                 ======================================================================== */                 $('#back-top').click(function(e) {                     e.preventdefault();                     $('html, body').animate({                         scrolltop: 0                     }, 500);                 });              }              if ($winwidth > 700) {                 var slidewidth = true;             }         }

one error appearing in console: var slidewidth not definited.

what doing wrong? have tried several ways of writing none of them work...

during document ready, haven't defined here:

$('#slider').lightslider({     item:1,     slidemove:1,     slidemargin: 30,     loop: true,     autowidth: slidewidth });

at above stage not defined. make accessible in higher scope:

$(document).ready(function () {   var slidewidth = false;   updatecontainer();   $(window).resize(function() {     updatecontainer();   });    $('#slider').lightslider({     item:1,     slidemove:1,     slidemargin: 30,     loop: true,     autowidth: slidewidth   }); });

make var slidewidth = false; goes global scope. , when execute updatecontainer() update global variable.

and make sure, in updatecontainer(), not using var:

function updatecontainer() {     var $winwidth = $(window).width();     if ($winwidth > 1100) {         slidewidth = false;     // other code }
