I am trying to incorporate a jquery function to automatically change the active status of the nav links in my Bootsrap Navbar. I have a base HTML file which extends into an app-specific base file. That file is then extended to the individual pages navigated by the navbar.
Here is the app-specific HTML:
{% extends "base.html" %}
{% load static %}
{% block css %}
<link rel="stylesheet" href="{% static 'home/main.css' %}">
{% endblock css %}
{% block js %}
<script>
$(function() {
$("#home-navs").click(function() {
// remove classes from all
$("#home-navs").removeClass("active");
// add class to the one we clicked
$(this).addClass("active");
});
});
</script>
{% endblock js %}
{% block content %}
<br>
<div class="container status-update">
<div class="container">
<form>
<div class="input-group-lg">
<input type="text" class="form-control" value="What's new?">
</div>
<br style="height:20px">
<button type="submit" class="btn btn-primary btn-lg" name="button">Post</button>
</form>
</div>
</div>
<br>
<div class="container">
<nav class="navbar navbar-expand-lg navbar-light" style="background-color: #6298bf">
<div class="collapse navbar-collapse" id="navbarSupportedContent">
<div class="navbar-nav">
<a class="nav-link active" id="home-navs" href="{% url 'home' %}">Activity Feed</a>
<a class="nav-link" id="home-navs" href="{% url 'vehicle-updates' %}">Vehicle Updates</a>
<a class="nav-link" id="home-navs" href="/space.html">Garage Updates</a>
</div>
</div>
</nav>
</div>
And then I have this in the head of my primary base.html file:
{% load static %}
<!doctype html>
<html lang="en">
<head>
<!-- Required meta tags -->
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<!-- Bootstrap CSS -->
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeNV6gBiFeWPGFN9MuhOf23Q9Ifjh" crossorigin="anonymous">
{% block css %}{% endblock css %}
<script src="{% static 'js/jquery-3.5.1.min.js' %}"></script>
<script src="{% static 'js/jquery.waypoints.min.js' %}"></script>
<script src="{% static 'js/infinite.min.js' %}"></script>
{% block js %}{% endblock js %}
<title>Test</title>
</head>
The page and links works just fine, I just can't get the active status on the navbar to change when I click the different links. I don't know if I am referencing the items in the function wrong, or what. Any guidance would be much appreciated. Thank you!
You can't use ids for multiple dom elements. Use classes instead.
Try to change it to this:
$(".nav-link").click(function() {
// remove classes from all
$(".nav-link").removeClass("active");
// add class to the one we clicked
$(this).addClass("active");
});
And if you want to scope it to only elements of a specific nav put the id in the nav itself and then use selector: $("#main-nav .nav-link")

I have a custom popup that shows upon form submission to let the user know it was successful. Currently it displays when it's supposed to (although I can't get it to display in the middle right on top, but that's a minor issue) like shown below:
But the little X button does not actually close the message. You can click it but it does nothing, and if you reload the page then it's gone until you submit again.

I think the problem could be related to the warning I get that says Unresolved function or method toast() on $('.toast').toast('show'); but I'm not sure how to resolve this issue (I got this from https://www.w3schools.com/bootstrap4/bootstrap_toast.asp but I don't know if I just didn't add something important to make this work)

The close button is missing the attribute data-dismiss="toast"
You'd need to add the toast class to the containing div though as well

I am working on incorporating a react front end with my flask website and am having trouble getting the react component to show up. I am able to use webpack to build and load in my modules without issue, but perhaps don't fully understand how to get the react side running.
Here is the html that holds the div (note, I use flask to simply extend my layout html):
{% extends 'layout.html' %}
{% block content %}
<body id = "aboutPage" data-spy="scroll" data-target = ".navbar" data-offset="60">
<div id = "date-root"> </div>
</body>
{% endblock content %}

import MyDayPicker from './daypicker';
ReactDOM.render(
<MyDayPicker />,
document.getElementById("date-root")
);
const element = <h1>Schedule</h1>;
console.log(element);
Lastly, here is the daypicker.js file which holds the react component and its code:
import React from 'react';
import DayPicker from 'react-day-picker';
import 'react-day-picker/lib/style.css';
export default class MyDayPicker extends React.Component {
constructor(props) {
super(props);
this.handleDayClick = this.handleDayClick.bind(this);
this.state = {
selectedDay: null,
};
}
handleDayClick(day, { selected }) {
this.setState({
selectedDay: selected ? undefined : day,
});
}
render() {
return (
<div>
<DayPicker
selectedDays={this.state.selectedDay}
onDayClick={this.handleDayClick}
/>
<p>
{this.state.selectedDay
? this.state.selectedDay.toLocaleDateString()
: 'Please select a day'}
</p>
</div>
);
}
}
Please help me figure out what I am missing! Thanks guys.
I'm not using flask so maybe I'm wrong... but it seems to me that you missed react script in *.html file. Please add:
<script src="<path to your react script - index.js" ></script>
You can check diagnose the problem by starting to see whether a native react component is loaded or not, like Router, if the problem didn't went away, if not, check the inspection console to see the error.
I'm trying to use Material Bootstrap Alert in my Django app. If user inputs wrong password or username while trying to login to the page, the error toast message should appear in the upper right corner. With js alert it works perfectly fine but when I'm trying to invoke toastr.error('Wrong login credentials. Please, try again...'); I get these erorrs:
jQuery.Deferred exception: toastr is not defined #http://127.0.0.1:8000/login/:63:9

I'm not very experienced with JS or jQuery. All javascript files are from official MDB website.
Found the reason of error. I've been using version of framework which don't have toast messages
I started a project on Django.
In one of my app, I did a template with a two menu, one black one white with fade in and fade out (using semantic ui )
here the code
<!-- Menu fixe -->
<div class="ui large top fixed hidden menu" >
<div class="ui container">
<a class="active item" id="acc_menu">Accueil</a>
<a class="item">Comment ça marche </a>
<a class="item">Vous voyagez ?</a>
<!-- <a class="item">besoin 1</a> -->
<div class="right item">
<a class="ui inverted red button" id="connexction1">Connecxion</a>
<a class="ui inverted red button" id="inscription1">Inscription</a>
</div>
</div>
</div>
<!-- Menu noir -->
<div class="pusher">
<div class="ui inverted segment" id="menu_fixe">
<div class="ui container">
<div class="ui large secondary inverted pointing menu">
<a class="active item" id="acc_menu">Accueil </a>
<a class="item">Comment ça marche </a>
<a class="item">Vous voyagez ?</a>
<!-- <a class="item">besoin 1</a> -->
<div class="right item">
<a class="ui inverted red button" id="connexction">Se connecter</a>
<a class="ui inverted red button" id="inscription">S'inscrire</a>
</div>
</div>
</div>
</div>
</div>
{% block extrahead %}
<! -- other loading --!>
<script src="{% static 'js/base.js' %} "></script>
<link rel="stylesheet" type="text/css" href="{% static 'css/base.css' %} "/>
{% endblock %}
with this js file : base.js
$(document).ready(function() {
// fix menu when passed
$('#menu_fixe')
.visibility({
once: false,
onBottomPassed: function() {
$('.fixed.menu').transition('fade in');
},
onBottomPassedReverse: function() {
$('.fixed.menu').transition('fade out');
}
})
;
})
;
that work fine,but when I add a slider on a homepage, with the template linked the fade in - fade out don't work anymore!
here my homepage code:
<!DOCTYPE html>
{% extends "home/base.html" %}
{% load static %}

I have another js file : "accueil.js" for the slideshow and it's work fine.
all my setting are good too :

STATICFILES_DIRS = (BASE_DIR + '/static',)
