Codifica HTML
Encode special HTML characters instantly for secure web display.
When you’re creating HTML content for the web, certain characters are reserved. Characters such as < and & have special roles in HTML that can confuse browsers if not carefully handled. That’s where encoding steps in to save the day!
So, How Does HTML Encoding Help?
Here's what makes HTML encoding super handy:
- Safeguarding Special Characters: By transforming characters like < into < and & into &, you're effectively speaking the web's language, ensuring everything's smooth sailing.
- Keeping Code Intact: Trying to display code snippets? Encoding stops browsers from misreading them as commands.
- Preventing Mishaps on Display: This process ensures all content shows up correctly without any accidental formatting or display issues.
Such a tool is especially handy for anyone dealing with web content, whether you're a developer building sites or a creator putting together online articles about code.
Why Would You Need to Encode URLs?
Similar to HTML encoding, URL encoding (or percent encoding) comes in when URLs include characters that might trip things up. Here’s why it’s necessary:
- Control Mischievous Characters: URLs don’t take kindly to characters like ?, &, or / messing about.
- Safe Passage: Encoding ensures these tricky customers are properly escorted across the internet intact.
- Readable Structure: It turns hazardous characters into safe numeric codes preceded by %, like turning spaces into %20.
Using JavaScript for HTML Encoding
function htmlEncode(htmlText) {
let element = document.createElement('div');
element.innerText = htmlText;
return element.innerHTML;
}
let htmlText = "<p>Hello, World!</p>";
let encodedHtml = htmlEncode(htmlText)
console.log(encodedHtml); // Outputs: <p>Hello, World!</p>
HTML Encoding in C#
var htmlText = "<h1>Welcome!</h1>";
var encodedText = HttpUtility.HtmlEncode(htmlText);
Console.WriteLine(encodedText); // Outputs: <h1>Welcome!</h1>
