In my blog I'm using Pico CMS, in the index.twig page I wrote this code that generates HTML with page title, description, and URL:
{% for page in pages|sort_by("time") %}
{% if page.id starts with "blog/" %}
<div class="post">
<h3>
<a class="page-title" href="{{ page.url }}">{{ page.title }}</a>
<small class="date">{{ page.date }}</small>
</h3>
<p class="excerpt">{{ page.description }}</p>
{% endif %}
{% endfor %}
My idea was to make each title in a different color, I used randomColor, and wrote this JavaScript:
$('.page-title').css('color', randomColor() );
But this makes all the page-titles in the page to be of same color, I would like each of them in a different color.
This is the website: blog.lfoscari.com
$('.page-title').css('color', randomColor() ); in plain english is Call the function randomColor() and get the colour and then set the same to all the elements matching the class.
You've to use each() to iterate over all elements, get the random colour by calling the function and set it to each element individually.
$('.page-title').each(function() {
$(this).css('color', randomColor())
});
You can use css() with callback , it will iterate over elements and you can update value by returning
$('.page-title').css("color", randomColor);

<div class="page-title">1</div>
<div class="page-title">1</div>
<div class="page-title">1</div>
<div class="page-title">1</div>
<div class="page-title">1</div>
<div class="page-title">1</div>
Twig has a random function that you can use:
<a class="page-title"
style="color: {{ random(['orange', 'pink', 'LightSkyBlue']) }}"
href="{{ page.url }}">{{ page.title }}</a>

I have a small problem with markdown in my flash project.
I want markdown to work for all posts, currently it only works for the first post. I suspect I need to use some kind of loop, but I don't know what to do to make it work.
Code:
{% extends "layout.html" %}
{% block content %}
<article class="media content-section">
<div class="media-body">
{% for post in document.posts %}
<div class="article-metadata">
<h3><a class="article-title" href="{{ url_for('posts.post', post_id=post.id) }}">{{ post.title }}</a></h3>
<p class="article-content">{{ post.content }}</p>
</div>
{% endfor %}
</div>
</article>
<script>
const content_text = document.querySelector(".article-content");
content_text.innerHTML = marked(content_text.innerHTML);
</script>
{% endblock content %}
Pic of the posts on website
querySelector returns the first element with the class. You need to use querySelectorAll to get all the elements and then use for loop to loop and apply markdown to each element.
const content_text = document.querySelectorAll(".article-content");
for (i = 0; i < content_text.length; i++){
content_text[i].innerHTML = marked(content_text[i].innerHTML);
}
I'm trying to add divs to product descriptions in Shopify so that I can then create an accordion.
Currently my code looks like this
In the .liquid file:
<div class="product-single__description rte">
{{ product.description }}
</div>
This is the output:
<div class="product-single__description rte">
<h2>TEXT</h2>
<h4>TEXT</h4>
<p><em>Text</em></p>
<h4>TEXT</h4>
<p>Text</p>
<h2>TEXT</h2>
<h4>Text</h4>
<p>Text</p>
<h4>TEXT</h4>
<p>Text</p>
<h4>TEXT</h4>
<p>Text</p>
<p><em>Text</em></p>
</div>
My goal is to insert a div wrapper and enclose the content from H2 to the next h2, so for example:
<div class="product-single__description rte">
<div class=“class_1”
<h2>TEXT</h2>
<h4>TEXT</h4>
<p ><em>Text</em></p>
<h4>TEXT</h4>
<p>Text</p>
</div>
<div class=“class_2”
<h2>TEXT</h2>
<h4>Text</h4>
<p>Text</p>
<h4>TEXT</h4>
<p >Text</p>
<h4>TEXT</h4>
<p>Text</p>
<p><em>Text</em></p>
</div>
</div>
The number of H2s and the content changes from product to product.
Well there are a few checks that you need to make before you do this.
First we will set a variable for the content:
{% assign content = product.description %}
After that we will check if the if there is a plain <h2> in there
{% if content contains '<h2>' %}
// logic to add here
{% else %}
{{content}}
{% endif %}
(have in mind that if your h2 tags have any inline styles you will have to target <h2 instead)
If there is we will continue the logic inside the if, but if there is not we will output the plain content in the else statement.
So we are now in the // logic to add here part here.
We will split the content by <h2> like so:
{% assign content_arr = content | split: '<h2>' %}
We will check if you have some content before the first <h2> since we don't want to loose it in that case, so we check it like so:
{% if content_arr[0] != '' %}
{{content_arr[0]}}
{% endif %}
We need to loop the rest of the items of the array.
Since we are splitting by <h2> if there is no content before the <h2> it will return an empty array for the first item and we don't need that one. So we will offset the for loop by 1 item:
{% for item in content_arr offset: 1 %}
// items here
{% endfor %}
Now we need to return the opening <h2> tag (since we removed it from the content) and show the rest of the content.
It's easy as writing <h2> before the {{item}}:
<div class="class_{{forloop.index}}">
<h2>{{item}}
</div>
And that's all.
Here is the full code:
{% assign content = product.description %}
{% if content contains '<h2>' %}
{% assign content_arr = content | split: '<h2>' %}
{% if content_arr[0] != '' %}
{{content_arr[0]}}
{% endif %}
{% for item in content_arr offset: 1 %}
<div class="class_{{forloop.index}}">
<h2>{{item}}
</div>
{% endfor %}
{% else %}
{{content}}
{% endif %}
You may try this (not tested but it should work):
{% assign desc_parts = product.description | split:'<h2>' %}
{% for part in desc_parts offset:1 %}
<div class="class_{{ forloop.index }}">
{{ part | prepend:'<h2>' }}
</div>
{% endfor %}
Explanations:
As you do not have clean separator in product description, let's use
h2 tag.
Then, you create an array with this separator (split
function).
Then you loop through your array, with an offset to 1 to
avoid the empty first elem (or you may use it later or before to display it in a separated div it there is something before the first h2 tag). To display separately the first elem, use {{ desc_parts.first }}.
To get a unique class or id, you may
use the loop index.
As the h2 tag is the separator used to create
the array, you need to prepend your elem with it.
Please note that you should also think about the case with a product description without h2 and manage this case in your code.
I have several posts each of them composed of three parts : a title, a username/date and a body. What I want to do is to show the body when I click on either the title or the username/date and hide it if I click on it again. What I've done so far works but not as expected because when I have two or more posts, it only shows the body of the last post even if I click on another post than the last one. So my goal is only to show the hidden text body corresponding to the post I'm clicking on. Here is my code:
{% extends 'base.html' %}
{% block header %}
<h1>{% block title %}Test page{% endblock %}</h1>
<a class="action" href="{{ url_for('main_page.create') }}">New</a>
{% endblock %}
{% block content %}
{% for post in posts %}
<article class="post">
<header>
<script language="JavaScript">
function showhide(newpost)
{var div = document.getElementById(newpost);
if (div.style.display !== "block")
{div.style.display = "block";}
else {div.style.display = "none";}}
</script>
<div onclick="showhide('newpost')">
<h1>{{ post['title'] }}</h1>
<div class="about">by {{ post['username'] }} on {{ post['created'].strftime('%d-%m-%Y') }}</div>
</div>
</header>
<div id="newpost">
<p class="body">{{ post['body'] }}</p>
</div>
</article>
{% if not loop.last %}
<hr>
{% endif %}
{% endfor %}
{% endblock %}
Of course I looked for a solution as much as I could but I'm kind of stuck plus I'm a complete beginner in HTML/JS/CSS. And one last thing, I'm currently using Python's framework Flask. Thank you by advance.
You need to give each of your posts a unique id for your approach to work.
Change your code to
<div id="{{post_id}}">
<p class="body">{{ post['body'] }}</p
</div>
where post_id is that post's unique id e.g. its id in the database you are using that you pass to the template in your view. Then, change the call to the onclick event handler to
<div onclick="showhide('{{post_id}}')">
If you don't have a unique id you can also use the for loop's index: replace all post_id instances above with loop.index. See Jinja's for loop docs for more information.
here I am passing {{id}} to hide_show(...) javascript function
{% for stock in part_temp.part_stock_set.all %}
{% with id="list"|concatenate:stock.id %}
<div id="{{ id }}">
{{ stock.entry_date}}
</div>
<button type="button" onclick="hide_show({{ id }})">edit</button>
<br>
{{ id }}
here above the {% endwith %} {{ id }} is displaying correctly but the hide_show function in not called but it is called when just {{ stock.id }} is passed to it.
the concatenate filter just concatenates and returns a string.
<script type="text/javascript">
function hide_show(temp) {
document.getElementById(temp).style.display='none';
window.alert(temp);
}
</script>
Problem seems to be with the quotes. if {{ id }} returns a string, then you don't have to put quotes here
<div id="{{ id }}">
Simply replace it with:
<div id={{ id }}>
If id is an integer or if the above doesn't work, then you have to put quotes here as well as in the argument while calling the hide_show function.
in jekyll, this works:
---
layout: default
---
<div class="brief">
<ul>
{% for post in site.posts %}
<li class="postlist">
<a href="#" onclick='document.getElementById("one").innerHTML="{{post.url}}";'>{{post.title}}</a>
<p>{{post.meta}} <br>{{post.date}} <br>{{post.category}}</p>
</li>
{% endfor %}
</ul>
</div>
<div class="post" id="one"></div>
but when i change line #8 to:
<a href="#" onclick='document.getElementById("one").innerHTML="{{post.content}}";'>{{post.title}}</a>
it breaks. why does this happen and what can i do to change this and get the desired outcome?
It's likely that your post content is creating invalid HTML (e.g. ending the onclick quotes).
In my opinion, a better method to achieve this would be to render all the post content hidden, and have your onclick toggle a class to display the relevant content. This would save you from the untold horrors of encoding and decoding that content through an attribute value.
For example:
{% for post in site.posts %}
<li>
<a href="#" onclick='document.getElementById("post-content-{{ forloop.index }}").classList.toggle("hidden")'>{{ post.title }}</a>
<p>{{ post.meta }} <br>{{ post.date }} <br>{{ post.category }}</p>
<p id="post-content-{{ forloop.index }}" class="hidden">{{ post.content }}</p>
</li>
{% endfor %}
External CSS:
.hidden {
display: none;
}
You could also extend this to hide all content sections first, so only one is shown at a time.
