I have a custom button in the a header next to a "cart" link. Website uses AJAX cart. When an item is added to cart, the cart link enlarges to include nr of items in cart. This causes the cart link to overflow and overlap the custom button next to it. Essentially what I'm trying to achieve is to add a margin to the custom button when an item is added to cart and the cart link is expanded. My first thought was to wrap both in a div and use CSS flex to adjust the sizing of both, however, and please correct me if I'm wrong, I thought it would be quicker to just write a script that would add a margin to my custom button. Definitely didn't turn out to be the quicker way as I've been stuck on it for hours now - any help would be greatly appreciated. I've browsed through similar posts and couldn't find a result that I want - any help would be greatly appreciated (I'm still new to JS and jQuery but learning). Below is the code and some of the things that I've tried.
HTML - header
<div class="header--menu">
<div class="custom-btn-container">
Quick Order
</div>
{%
render 'framework--x-menu',
js_class: 'XMenu',
align: menu_alignment,
overlap_parent: 1,
handle: menu
%}
</div>
{% endif %}
<div class="header--cart">
{% render 'snippet-cart', cart_icon: cart_icon %}
</div>
</div>
HTML - cart
{% if settings.cart--type == 'drawer' %}
<div
class="cart--open-right off-canvas--open"
data-off-canvas--open="right-sidebar"
data-off-canvas--view="cart"
aria-haspopup=”menu”
>
{% endif %}
<a
class="header--cart-link"
data-item="accent-text"
href="{{ routes.cart_url }}"
aria-label="{{ 'layout.header.cart' | t }}"
>
{% if cart_icon == 'text' %}
{{ 'layout.header.cart' | t }}
{% elsif cart_icon == 'bag' %}
{% render 'framework--icons', icon: 'bag' %}
{% else %}
{% render 'framework--icons', icon: 'cart' %}
{% endif %}
<span class="header--cart-number" data-item-count="{{ cart.item_count }}">
(<span class="cart--external--total-items">{{ cart.item_count }}</span>)
</span>
</a>
{% if settings.cart--type == 'drawer' %}
</div>
{% endif %}
And these are some of the scripts that I've tried:
window.onload = () => {
if (jQuery('.header--cart-number').data('item-count') != '0') {
$(".custom-button").css('margin-right', '10px');
}
}
The above is nearly what I'm after, but only works after refreshing the page.
document.ajaxComplete = () => {
if (jQuery('.header--cart-number').data('item-count') != '0') {
$(".custom-button").css('margin-right', '10px');
}
}
similar story
$(document).ajaxSuccess(function() {
if (jQuery('.header--cart-number').data('item-count') != '0') {
$(".custom-button").css('margin-right', '10px');
}
}
This didn't do anything whatsoever.
I'm sure I'm missing something small, but it's driving me mad. Again, any help will be greatly appreciated!
Best,

I created a Django app with a form. when the form is submitted and found error, messages.error(request, e) is called, where e is the error text.
the real code
for field, errors in form.errors.items():
print('Field: {} Errors: {}'.format(field, ','.join(errors)))
e = 'Field: {} Errors: {}'.format(field, ','.join(errors))
messages.error(request, e)
if I have multiple errors, multiple error boxes pops up at same time, but I want to make a time difference of .5seconds between each error popup.
I saw time.sleep(0.5) but the issue is it just takes timegap inside forloop not in gap between the popup. There might be a JS fix, I would like to know how
here's my html code
{% if messages %}
{% for message in messages %}
{% if message.tags == 'alert-success' %}
<!-- Toast -->
<div data-toast data-toast-text="{{ message }}"
data-toast-gravity="top" data-toast-position="right" data-toast-className="success"
data-toast-duration="2000" class="noty-tost d-none rounded shadow bg-success"></div>
{% endif %}
{% if message.tags == 'alert-danger' %}
<!-- Toast -->
<div data-toast data-toast-text="{{ message }}"
data-toast-gravity="top" data-toast-position="right" data-toast-className="danger"
data-toast-duration="5000" class="noty-tost d-none rounded shadow bg-danger"></div>
{% endif %}
{% endfor %}
{% endif %}
$(document).ready(function () {
$('.noti-toast').click()
});
// used to trigger it(using toastify.js from a template, i don't really know much about it, but it works🫣)
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.
in a wtforms, I would like my SelectField to fill up with its selected value a StringField.
I use flask, bootstrap, and python 3.7
My HTML code is as follow:
{% block body %}
<h3>Edit Bloomberg ticker details</h3>
{% from "includes/forms/_form_helpers.html" import render_field %}
<div class="form-group" id="company_id" onchange="myFunction(event)">
{{render_field(form.company_names, class_="form-control")}}
</div>
<div class="form-group" id="isin_id">
{{render_field(form.isin_id, class_="form-control")}}
</div>
<script>
function myFunction(e) {
document.getElementById("isin_id").value = e.target.value
}
</script>
{% endblock %}
And the pyhon behind is as follow:
class DefTickerForm(_Form):
choices_companies = [(1,'Facebook'), (2, 'Google') ]
company_names = _SelectField(label='Company names:', choices=choices_companies, coerce=int)
isin_id = _StringField(label='isin_id', validators=[_validators.DataRequired], default=-1)
I would like that when the user select 'Facebook', the isin SelectField to be equal to 1. But so far it does nothing.
Note that if if code:
alert(e.target.value)
I get the wanted value. so issue is to set the TextField value.
my render field code is as followed (from a youtube tutorial):
{% macro render_field(field) %}
{{ field.label }}
{{ field(**kwargs)|safe }}
{% if field.errors %}
{% for error in field.errors %}
<span class="help-inline"> {{ error }}</span>
{% endfor %}
{% endif %}
{% endmacro %}
Any help would be much apreciated as google isn't so good on these.
Best
apparently TextField only accepts strings (I guess obvious if you are used to javascript)
so code working is as follow in case someone get he same problem:
<div class="form-group" onchange="myFunction(event)">
{{render_field(form.company_names, class_="form-control")}}
</div>
<div class="form-group">
{{render_field(form.isin_id, class_="form-control")}}
</div>
<script>
function myFunction(e) {
var x = e.target.value;
alert(x);
document.getElementById("isin_id").value = x.toString();
}
</script>
As a note, Jinja or anyway my render, use the fields names as default IDs (wich i realised using Chrome inpector. Meaning I didn't have to add an id for each Div. Anyway that is the thoughts of a beginenr in Javascripts.
So I have the following file structure:
plugins/myname/pluginname/components/pluginname/default.htm
plugins/myname/pluginname/components/PluginName.php
default.htm acts as the partial of the component.
and I have the following JS API
setInterval(function(){
$.request('onEverySecond', {
update: {'#default.htm':'#rate-marquee'},
complete: function() {
console.log('Finished!');
}
})
}, 1000);
onEverySecond is a function in PluginName.php that updates a variable called fx thrown to default.htm.
At the front end the partial default.htm seems to be updated, but it refreshes the whole partial which is not what I want, it causes the marquee to replay again and again and only be able to show the first few piece of contents.
All I wanted is that the AJAX will update only the variable fx where the data is updated.
How can I achieve that?
EDIT 1:
Here is the partial markup:
{% set fx = __SELF__.fx %}
<marquee id="rate-marquee" name="rate-marquee" onmouseover="this.stop();" onmouseout="this.start();">
<ul>
{% for item in fx %}
<li>
{{ item.Item | trim('u')}}: {{ item.BID }} {% if item.Revalue == 0 %} <div class="arrow-up"></div> {% else %} <div class="arrow-down"></div> {% endif %}
</li>
{% endfor %}
</ul>
</marquee>
Additionally, here is the code in PluginName.php
public function onRun()
{
$this->addJs('/plugins/SoyeggWebDevelopment/fxmarquee/assets/js/default.js');
$this->updateFX();
}
public function onEverySecond()
{
$this->updateFX();
}
public $fx;
So updateFX() works perfectly well too.
Here problem seems you are replacing whole marquee it causes to re-render it.
To solve this we can just update portion inside marquee
setInterval(function(){
$.request('onEverySecond', {
complete: function() {
console.log('Finished!');
}
})
}, 1000);
We don't do anything special here just a simple ajax call
to update portion of marquee we need to assign id to it and we define internal partial
<marquee id="rate-marquee"
name="rate-marquee"
onmouseover="this.stop();" onmouseout="this.start();">
<ul id='rate-marquee-inner'> <!-- <= here -->
{% partial __SELF__ ~ '::_marquee_inner' %}
</ul>
</marquee>
_marquee_inner.htm partila markup
{% set fx = __SELF__.fx %}
{% for item in fx %}
<li>
{{ item.Item | trim('u')}}: {{ item.BID }} {% if item.Revalue == 0 %} <div class="arrow-up"></div> {% else %} <div class="arrow-down"></div> {% endif %}
</li>
{% endfor %}
and to update that portion we just need to return markup array
function onEverySecond() {
$this->updateFX();
return ['#rate-marquee-inner' => $this->renderPartial('_marquee_inner.htm')];
}
this will just push new updated markup to given id #rate-marquee-inner so now it will just update inner portion of marquee and marquee will not re-render.
if any doubt please comment.
I have been working through the Tango with Django exercises to cut my teeth into Django. Almost done but having a problem with the Ajax part.
Ajax function to auto_add a page is not being called. Idk what the problem is since the other functions are being called.
On the shell prompt, there is no call to the ajax function at all. Help needed.
Pertinent code attached. It is the same as on the website link above.
static/rango-ajax.js
$('.rango-add').click(function(){
var catid = $(this).attr("data-catid");
var title = $(this).atrr("data-title");
var url = $(this).attr("data-url");
$.get('/rango/auto_add_page/', {category_id: catid, url: url, title: title}, function(data){
$('#pages').html(data);
me.hide();
});
});
templates/rango/category.html
{% if user.is_authenticated %}
<button data-catid="{{category.id}}" data-title="{{ result.title }}" data-url="{{ result.link }}" class="rango-add btn btn-mini btn-info" type="button">Add</button>
{% endif %}
rango/views.py
#login_required
def auto_add_page(request):
context = RequestContext(request)
cat_id = None
url = None
title = None
context_dict = {}
if request.method == 'GET':
cat_id = request.GET['category_id']
url = request.GET['url']
title = request.GET['title']
if cat_id:
category = Category.objects.get(id=int(cat_id))
p = Page.objects.get_or_create(category=category, title=title, url=url)
pages = Page.objects.filter(category=category).order_by('-views')
#Adds our results list to the template context under name pages.
context_dict['pages'] = pages
return render_to_response('rango/page_list.html', context_dict, context)
rango/urls.py
urlpatterns = patterns('',
url(r'^$', views.index, name='index'),
url(r'^goto/$', views.track_url, name='track_url'),
url(r'^add_category/$', views.add_category, name='add_category'),
url(r'^auto_add_page/$', views.auto_add_page, name='auto_add_page'),
Complete code is at this link.
your code is good, the only thing what you have to do is to define your template in /tango/templates/rango/page_list.html. This template have the following code:
{% if pages %}
<ul>
{% for page in pages %}
<li>
{{ page.title}}
{% if page.views > 1 %}
({{page.views}} views)
{% elif page.views == 1 %}
({{page.views}} view)
{% endif %}
</li>
{% endfor %}
</ul>
{% else %}
<strong> No Pages currently in category. </strong>
{% endif %}
And inside of your category template you must define the following code:
% if category %}
{% if user.is_authenticated %}
Add a new Page <br>
{% endif %}
{% if pages %}
<div id="pages">
<ul>
{% for page in pages %}
<li>
{{ page.title}}
{% if page.views > 1 %}
({{page.views}} views)
{% elif page.views == 1 %}
({{page.views}} view)
{% endif %}
</li>
{% endfor %}
</ul>
</div>
{% else %}
<strong> No Pages currently in category. </strong>
{% endif %}
{% else %}
The specified category {{ category_name }} does not exist!
{% endif %}
I'm working through this section of the tutorial now and just want to add to Héctor's answer. To avoid duplicating the code to display the list of pages I did the following:
I added a get_page_list() method to tango/rango/templatetags/rango_extras.py, similar to the get_category_list() method used to display a list of categories in an earlier section of the tutorial.
from rango.models import Page
#register.inclusion_tag("rango/page_list.html")
def get_page_list(category):
pages = Page.objects.filter(category=category) if category else []
return {'pages': pages}
Then we just need to load rango_extras and call the get_page_list() method in tango/templates/rango/category.html.
{% extends 'rango/base.html' %}
{% load rango_extras %}
<!-- Existing code -->
{% if category %}
<!-- Existing code to show category likes and like button -->
<div id="page_list">
{% get_page_list category %}
</div>
<!-- Existing code to show search if user is authenticated -->
{% else %]
The specified category {{ category_name }} does not exist!
{% endif %}
This allows you to display the list of pages when a category page is first loaded and then refresh it if a category is added from the search area, without having to duplicate any code.
