Is this code enough to preload images on my website? I use Django template langue for the loop, instead of javascript, like there. Is there any advantage of using javascript? Is my way as good as the javascript way?
{% for marker in markers %}
<img src="{{ marker.image }}" style="display: none"/>
{% endfor %}

When the first page is loaded, I want the user to come across all the music, but if he selects a list from RadioButton, I only want the music in that list, but the javascript function doesn't work.
Let me add that I don't normally know JavaScript, but I need to use it.
<div style = "margin-top : 100px;"class = "container">
{% for table in tables %}
<input type="radio" name="list1" onclick="mL('{{table}}')"> {{table}}
{% endfor %}
<div align="center">
<audio class="my_audio" controls="controls" autoplay="autoplay" style="width:500px;"></audio>
<ul>
{% for table in tables %}
{% for music in musics %}
<li style="list-style-type:None">
<a id="{{table}}" href="javascript:void(0);" onclick="playSong('{{music}}')">{{music}}</a>
</li>
{% endfor %}
{% endfor %}
{% for music in musics %}
<li style="list-style-type:None">
<a id="default" href="javascript:void(0);" onclick="playSong('{{music}}')">{{music}}</a>
</li>
{% endfor %}
</ul>
</div>
</div>
<script> function mL(x)
{
{% for table in tables %}
if (x=={{table}})
document.getElementById("{{table}}").style.display="block";
document.getElementById("default").style.display="none";
{% endfor %}
else
document.getElementById("{{table}}").style.display="none";
document.getElementById("default").style.display="block";
return;
}
</script>
This isn't a Django issue, it's purely about the JavaScript (or should be).
Here are some problems with your code:
In HTML, the id attribute should be unique in the document. You seem to have many <a> tags with the same id. Use the class attribute, or even better use your own data attribute like data-table.
You can code generate JavaScript using Django template tags like you have, but I think it's a bad idea because it's very hard to reason about how the code will work. Don't use {% for %} inside the <script> block.
JavaScript doesn't use spaces for code blocks like Python does. You need to use braces { } instead.
Once those things are fixed, use the debugging console in your browser (F12 in Firefox and Chrome). It will let you see any syntax errors, and you can even run code in the console to see how things like document.getElementById work.
I am trying to use the bootstrap carousel, but cannot really get it to work. I have a list with pictures I want to loop through and show in the carousel. I cannot show all the pictures since the "activate" (line 3 in the text below) only should be applied for the first picture (and not for the other ones in the list). This mean that I need some kind of restriction regarding the "activate". Probably something like "only use activate for the first loop-through". I'm not quite sure how to write that. I'm writing in javascript (newbie) and having a really hard time incorporating it in the html file.
<div class="carousel-inner">
{% for image in images %}
<div class="carousel-item active">
<img src="{{ url_for('static', filename='images/' + image.image) }}" alt="{{ name }} product image" class="d-block w-100">
</div>
{% endfor %}
</div>
You are using some template language here, I think Django.
You need to put class active in if block.
{% if image in images is first %} active {% endif %}
{% with %} {% endwith %}
I think you can use with syntax. This example is just logic you need to follow.
Just find the correct syntax. Other you do not need to change.
I am trying to merge JS files together in 1 file, however I need to set conditions using the if statements within the js file.
I have created file.js.liquid but it does not seem to working; I added a test for example:
{% if template contains 'index' %}
console.log('homepage loaded');
{% endif %}
Example of what i am trying to do, of course have plenty i need to do.
{% if settings.the_simpsons_enabled and settings.simpsons_video_enable %}
// video popup
$(".video-popup").videoPopup();
{% endif %}
The conditional statements are also not working within scss.liquid files either:
{% if template contains 'index' or template contains 'collection' or template contains 'product' %}
#import url("{{ 'owl.carousel.scss' | asset_url }}");
{% endif %}
Any ideas why if would not be working or if its even possible? I assume it is being a liquid file.
The Liquid extension on such files like CSS or JS allows use of Liquid variables but not statements.
So {{ write_my_liquid_var_here }} will work. {% if liquid_statement %}do something{% endif %} won't.
Regarding Shopify and SASS
The following won't work as you can't use #import in Shopify's SASS files.
#import url("{{ 'owl.carousel.scss' | asset_url }}"); //This will not work
Regarding using conditional liquid statements in .js.liquid files
I don't know everything about this subject, but I do know the following two things.
1) Check out this thread and you'll see that this type of statement won't work because js files are parsed independent of normal liquid templates, so it would have no idea which template you're viewing.
{% if template contains 'index' %} //This will not work
A better place to put the above logic would be at the bottom of your theme.liquid file above the </body> tag. However this won't help you with what seems to be your goal of reducing HTTP requests by using one JavaScript fie.
2) However, you can access values in your settings_data.json file
{% if settings.the_simpsons_enabled and settings.simpsons_video_enable %} //This will work
I hope this helps
On our online fashion store http://www.showstyle.lu I am the webmaster trying to improve the user experience perspective. I finally managed to use a toggle tool for our filters (click on any category: e.g. Homme) as you can see if you click on Couleurs/Tailles etc all the filters appear (they used to be displayed permanently which didn't look aesthethic).
Now, the issue is upon selection of filters the page is then reloaded with a new url to filter the products. Each time the filters then toggle back up of course and it's redundant to have to reclick each one and see what filter's one chose.
Is there a way I can either make the center content container refresh like php where the rest of the site remains static? Or otherwise can I at least force the toggle to remain open if the url has "%filter%*****" in it ?
We are using a ecommerce platform called SEOshop so I don't have access to every script/index page on the website but I have access to a large part.
The filters work on generation from backend so in the html code the placeholders are simply:
{% for filter in collection.filters.custom %} <a class="filtertitle" href="javascript:;">
<p>{{ filter.title }}</p>
</a>
{% for value in filter.values %}
<div class="filterbox2">
<div class="sidebar-filter-item clearfix">
<input id="filter_{{ value.id }}" type="checkbox" name="filter[]" value="{{ value.id }}" {% if value.active %} checked="checked"{% endif %} />
<label for="filter_{{ value.id }}">{{ value.title }}{% if not value.active and value.has_count %} <span>({{ value.count }})</span>{% endif %}</label>
</div>
</div>
{% endfor %}
{% endfor %}
</form>
</div>
Another topic, is it possible to have the toggle open a popup instead? Something to look like this: https://dl.dropboxusercontent.com/u/5636466/showstyle/mockup_filters.png
Thanks for any help, I will continue my research and post my attempts/anything I find :)
If you want to reload only a specific part of the website then there is no way to do it only with php. What you are trying to do will require ajax requests to load the data without reloading the page and javascript to determine where it should be displayed (I would recommend looking into a framework like angular for that). I don't know anything about your site backend but I'm guessing this is not a trivial change and will require you to learn about such things.
How to load http://example.myshopify.com/collections/all content
to my shopify frontpage http://example.myshopify.com/
I figured out a way that I hardcode <script>window.location.href='collections/all'</script> on index.liquid, but I'm pretty sure thats' not a clean way.
and I try to copy whole collection.liquid's code to index.liquid, but it prompt me Liquid error: Array 'collection.all.products' is not paginateable. error and no product showing the index.liquid page.
Any idea how to load collections/all on shopify's front page?
I'm using Timber Framework as people recommend to start to build a theme
inside
In the Timber framework, you could change this line in index.liquid:
{% for product in collections.frontpage.products limit:4 %}
to:
{% for product in collections.all.products %}
Depending on how many products you have, you probably still want to limit how many are displayed, or paginate the output.
E.g.
{% paginate collections.all.products by 12 %}
{% for product in collections.all.products %}
...
{% endfor %}
{{ paginate | default_pagination }}
{% endpaginate %}
You include this:
{% for product in collections.all.products %}
// here you have access to each product
{% endfor %}
This will loop all of your products.
You can review http://cheat.markdunkley.com/ what product variables you have access to in that loop.
