We will create a basic todo app to understand the basics of JavaScript. In this web app, one can create a todo list and can remove specific elements from the list.
Features or Functionalities to implement:
- Interactive and Responsive design
- Responsive Grid System
- Store and Delete items
Prerequisites: Basic knowledge of HTML, CSS, JavaScript, jQuery, and Bootstrap. Also, the user should be aware of how the grid system in Bootstrap works.
Setup: Create three files for HTML, CSS and JavaScript. To create these files run the following command:
- Syntax:
$ touch index.html index.css index.js
Step 1: Now edit index.html file.
<!DOCTYPE html>
<html lang="en" dir="ltr">
<head>
<meta charset="utf-8">
<title>todo</title>
<link rel="stylesheet" href="style.css">
<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href=
"https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css">
</head>
<body>
<div class="container">
<h1 class="row">
TODO APP
</h1>
<br/><br/>
<div class="row">
<form class="form-inline col-sm-offset-3">
<div class="input-group">
<span class="input-group-addon">
<i class="glyphicon glyphicon-pencil"></i>
</span>
<input type="text" class="form-control"
placeholder="todo-item"
id="box" style="width: 30vw" />
</div>
<div class="form-group">
<input type="button"
class="btn btn-primary form-control"
value="add" style="width: 10vw"
onclick="add_item()" />
</div>
</form>
</div>
<div class="row">
<ul id="list_item">
</ul>
</div>
</div>
<script type="text/javascript" src="main.js"></script>
</body>
</html>
Step 2: Now, add some CSS property to index.css file.
* {
padding: 0;
margin: 0;
box-sizing: border-box;
font-family: cursive;
}
body {
background: #f2f2f2;
overflow: auto;
}
h1{
text-align: center;
margin: 5%;
font-size: 3rem;
text-decoration: underline;
}
ul {
text-align: left;
padding-left: 10%;
padding: 7%;
font-size: 2rem;
list-style: circle;
}
li:hover{
color:red;
margin: 4%;
transition: 1.5s ease;
cursor: pointer;
}
Step 3: Edit index.js file and add some functionality.
// Function called while clicking add button
function add_item() {
// Getting box and ul by selecting id;
let item = document.getElementById("box");
let list_item = document.getElementById("list_item");
if(item.value != ""){
// Creating element and adding value to it
let make_li = document.createElement("LI");
make_li.appendChild(document.createTextNode(item.value));
// Adding li to ul
list_item.appendChild(make_li);
// Reset the value of box
item.value=""
// Delete a li item on click
make_li.onclick = function(){
this.parentNode.removeChild(this);
}
}
else{
// Alert msg when value of box is "" empty.
alert("plz add a value to item");
}
}
Output:
