Hello. I want to ask you for advice. There is a multipage site , a bunch of js scripts on the site, everything works well. But on one of the pages of the site (for registered users, in your account, ad page -> add ad) the script (just a modal fancybox) is very slow. On the remaining pages, everything works quickly and flawlessly (the link that calls the script is located in the header of the site). Slowly it loads on the page where there is a form that also selects cities, regions, etc. (code below). Data is taken from the context! In Chrome, the download takes 25-28 seconds. 2.5 seconds in FireFox enter image description here

{% load hosts %} <div class="b-header"> <div class="b-header__menu"> <div class="container"> <div class="row"> <div class="col-xs-12"> <div class="b-menu"> <a>...</a> <a>...</a> <a>...</a> <a>...</a> <span class="b-menu__item btn_change-location"> <a href="#change-location" class="fancybox dashed"> {% if user.is_authenticated %} Просмотр объявлений на территории: {% if user.districts.all.count > 1 %} {% for district in user.districts.all %} {% if forloop.last %} <span>{{ district }}</span> {% else %} <span>{{ district }},</span> {% endif %} {% endfor %} {% else %} {% for district in user.districts.all %} <span>{{ district }}</span> {% endfor %} {% endif %} {% if user.regions.all.count > 1 %} {% for region in user.regions.all %} {% if forloop.last %} <span>{{ region }}</span> {% else %} <span>{{ region }},</span> {% endif %} {% endfor %} {% else %} {% for region in user.regions.all %} <span>{{ region }}</span> {% endfor %} {% endif %} {% if user.cities.all.count > 1 %} {% for city in user.cities.all %} {% if forloop.last %} <span>{{ city }}</span> {% else %} <span>{{ city }},</span> {% endif %} {% endfor %} {% else %} {% for city in user.cities.all %} <span>{{ city }}</span> {% endfor %} {% endif %} {% else %} Просмотр объявлений на территории: {% endif %} </a> </span> </div> </div> </div> </div> </div>

Template modals (data retrieval from content)

 {% load hosts %} {% load widget_tweaks static %} <div id="change-location"> <form action="{% host_url "setlocation" host "www" %}" method="post"> {% csrf_token %} <div id="chose-city-wrap"> <div class="b-modal__title">Выберите ваш город</div> <p> <div class="b-modal__item"> <span>{{ location_form.country.label }}</span> {{ location_form.country }} </div> </p> <p> <div class="b-modal__item"> <span>{{ location_form.districts.label }}</span> {{ location_form.districts }} </div> </p> <p> <div class="b-modal__item"> <span>{{ location_form.regions.label }}</span> {{ location_form.regions }} </div> </p> <p> <div class="b-modal__item"> <span>{{ location_form.cities.label }}</span> {{ location_form.cities }} </div> </p> <br /> <div class="b-modal__item b-modal__item_btn"> <input class="b-btn b-btn_red" type="submit" value="Сохранить"> </div> </div> </form> </div>

Download cities on the page where modalka slows down!

 <fieldset> <legend>Территория распространения объявления</legend> {{ form.country|add_class:"b-input__input js-select" }} {{ form.districts|add_class:"b-input__input js-select chosen-select" }} {{ form.regions|add_class:"b-input__input js-select chosen-select" }} {{ form.cities|add_class:"b-input__input js-select chosen-select" }} {# form.geo|add_class:"b-input__input" #} </fieldset>

  • @ Duck I understand that everything is not telepathic here, it may just happen that someone, what could be the reasons for this behavior, when everything works fine, and on one page it loads the script for about 10 seconds ... - b-ars07
  • so long what's going on? loads the script over the network? house redraw? or logic hangs? Or is some crap memory clogged? or for example with a script in addition loaded porn with horses? (Well, not to download it, this icon for the "close" button should be taken from somewhere). In the developer console, there are tools for debugging all this - Duck Learns to Take Cover
  • For just the template code, it is impossible to reproduce the problem, give something that we will run and that we will also slow down - andreymal
  • @ b-ars07, clear the browser's cache, open the developer’s tools in the browser on the “network” tab and load the page of your site. Show this temporary loading pattern. - Visman

If the script is in the header, then it is worth seeing what is loaded in front of it. These are probably css and other scripts. On this page in the css some big pictures may be indicated, for example. Look at the network tab in the developer console to see exactly what is being loaded.
