What is URL Encode?
URL Encoding is the process of converting characters into a format that can be transmitted over the internet. It is a way to convert characters that are not allowed in a URL into a format that can be transmitted without any issues.
For example, if you want to send a URL that contains special characters like spaces, #, %, etc., then those characters need to be converted into a format that can be safely transmitted. This is where URL Encoding comes into play.
How Does URL Encoding Work?
URL Encoding works by converting characters into their ASCII code value, which is a numerical representation of the character. For example, the ASCII code for the letter 'A' is 65.
Once the ASCII code is determined, it is then converted into hexadecimal format, which is a base-16 numbering system. Hexadecimal values range from 0-9 and A-F, where A-F represents values 10-15.
The hexadecimal value is then preceded by a '%' symbol, which indicates that it is a URL encoded character.
Why is URL Encoding Important?
URL Encoding is important because it allows us to transmit special characters and non-ASCII characters over the internet without any issues. It helps to ensure that data is transmitted correctly and that there are no errors or issues with the transmission.
How to URL Encode in HTML
To URL Encode in HTML, you can use the encodeURIComponent() function in JavaScript. This function will encode a string so that it can be safely transmitted over the internet.
var url = "https://example.com/?name=John Doe";
var encodedUrl = encodeURIComponent(url);
This will encode the URL and store the encoded string in the encodedUrl variable.
You can also URL Encode in HTML using the % symbol followed by the hexadecimal value of the character. For example, if you want to encode a space, you would use %20.
Here is an example:
https://example.com/?name=John%20Doe
In this example, the space in the name has been encoded as %20.
