Menu
I am trying to have a counter showing the total number of tasks that are aren't complete. The complete ones are marked by line-through when clicked. When i click on each list the total number also should reduce by 1. I created a variable representing the total number - 1 but the total number only reduce once only at first click. Please i am stuck at these and i am still new on jQuery.
This is my code
$(document).ready(function() {
$('button').on('click', function() {
// Create variable to represent the value
var $value = $('input').val()
// Putting the values as list in web browser using if and else.
if ($value === "") {
alert("Enter your to do list")
} else {
$('.list').append("<li>" + $value + "</li>")
}
//Creating variable that will hold totoal number of list
var $count = $('li').length;
// Creating variable to repersent list subtraction
var $sub = $count - 1;
var $solution = $sub--;
// Underline the list when cliked by user
$('li').on("click", function() {
$(this).css('text-decoration', 'line-through')
$('.text').text("You have " + $solution + " uncompleted tasks")
});
});
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

You can play with a class line to achieve what you need. Avoid nested click events, check the example:
$(document).ready(function() {
var $count;
var $sub;
$('button').on('click', function() {
// Create variable to represent the value
var $value = $('input').val()
// Putting the values as list in web browser using if and else.
if ($value === "") {
alert("Enter your to do list")
} else {
$('.list').append("<li>" + $value + "</li>")
}
$count = $count + 1;
$('.text').text("You have " + $count + " uncompleted tasks")
});
// Underline the list when cliked by user
$(document).on("click", "li:not(.line)", function() {
$count = $('li:not(.line)').length;
$(this).addClass("line")
$count = $count - 1;
$('.text').text("You have " + $count + " uncompleted tasks")
});
});.line{
text-decoration: line-through;
}
h2 {
text-align: center;
}
body {
margin: 0;
padding: 15px 0 0 15px;
border-collapse: none;
}
li {
font-size: 20px;
font-family: 'candara';
