javascript - loading a markup if a class exists -

-

i want load markup documents based on present of classes in document.but problem if definite class not exists @ loads.

my codes are

(function($){    'use strict';     var prefixmarkup = '<ul class="filter-elements hidden" >'+                           '<li><a href="#" class="current"></a></li>'+                         '</ul>';      if($('body').has('.filter-container')){       if(!$('body').hasclass('filter-elements')){         $('footer.footer').before(prefixmarkup)       }     } })(jquery);

here if .filter-container not exists prefixmarkup loads , if .filter-elements exists prefixmarkup loads should now?

first:

  • the .hasclass() method return true if class assigned element, if other classes are.
  • the .has() method constructs new jquery object subset of matching elements.

your need change:

if($('body').has('.filter-container')){

to:

if($('body').has('.filter-container').length){
