How to encode URL in JavaScript?
Answer: Using encodeURI() and encodeURIComponent() method
In this lesson, we are going to learn how to encode the URL using JavaScript. So there are two built-in methods offered by JavaScript that help to encode the URL, these methods are:
- encodeURI() method
- encodeURIComponent() method
Let's discuss both methods in detail
Using encodeURI() method
The encodeURI() method is used to encode the URI. This function encode all the special characters except , / ? : @ & = + $ #.
Example: Using encodeURI() method
In the given example, we have encoded the URL using encodeURI() method.
<!DOCTYPE html>
<html>
<head>
<title>Encode URL</title>
</head>
<body>
<button onclick="myFunction()">Click here</button>
<p id="demo"></p>
<script>
function myFunction() {
var uri = "https://www.studytonight.com/";
var result = encodeURI(uri);
document.getElementById("demo").innerHTML = result;
}
</script>
</body>
</html>
Output
Using encodeURIComponent() method
We can encode URL in JavaScript using encodeURIComponent() method. This method encodes the URI components. It replaces each instance of a certain character with one two or three or four escape sequences representing the UTF-8 encoding of the character.
This function encodes special characters, these characters are , / ? : @ & = + $ #.
Example: Using encodeURIComponent() method
In the given example, we have used the encodeURIComponent() method to encode the given URL.
<!DOCTYPE html>
<html>
<head>
<title>Encode URL</title>
</head>
<body>
<button onclick="myFunction()">Click Here</button>
<p id="demo"></p>
<script>
function myFunction() {
var url = "https://www.studytonight.com/";
var encode = encodeURIComponent(url);
document.getElementById("demo").innerHTML = encode;
}
</script>
</body>
</html>
Output
Conclusion
In this lesson, we have learned how to encode the URL in JavaScript. Basically, there are two built-in methods offered by JavaScript which allow us to encode the URL, these methods are encodeURI() and encodeURIComponet() method. Both the method functions same but there is a slight difference in both. The encodeURI() method does not encode the special characters while the encodeURIComponent() method does.
