In this tutorial, we will learn how to count the number of characters in a string using jQuery.
We will use the .length
property to find the number of characters in the string, and also find the length of the string with space and without spaces.
Syntax -
string.length
Character count with space
In this example we will count the number of characters with space in a string using jQuery.
<!DOCTYPE html>
<html>
<head>
<title>Count the number of characters in a string with space using jQuery</title>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
</head>
<body>
<h1>Count the number of characters in a string with space using jQuery</h1>
<input type="text" name="string" value="welcome to teknowize" class="input2">
<button class="clkbutton">Click Me!</button>
<script>
$(document).ready(function(){
$('.clkbutton').click(function(){
var countInput = $('.input2').val().length;
alert(countInput);
});
});
</script>
</body>
