jquery - "If default.html exists within folder then" function -


is there easy way script function based off file existing or not in particular folder? perhaps running 404 test against folder?

for example:

if default.html exists in child directory preview, ... else ...?

thanks help.

you this:

function exists(url) {     var request = $.ajax({         type: 'head',         async: false,         url: url     });      return request.status === 200; }

i wouldn't use this, however. it's blocking call , momentarily lock browser. use error callback of ajax function , make request asynchronous:

$.ajax({     type: 'head',     url: url }).fail(function(request, status, error) {     // error }).done(function(data, status, request) {     // success });

better yet, don't @ all.
