Html entity decode jquery

How to decode HTML entities using jQuery?

HTML entities are special characters that are used to display symbols, such as © for ©. These entities can be difficult to read and understand, and jQuery provides an easy way to decode them into their corresponding symbols.

Method 1: Using jQuery

You can use jQuery’s `html()` function to decode HTML entities. Simply pass the encoded string as the parameter, and the function will return the decoded string.

var encodedString = "
This is an encoded string.
"; var decodedString = $("").html(encodedString).text(); console.log(decodedString); 

In the above code, we first define the encoded string `encodedString`. We then create a new `div` element using jQuery and set its HTML content to the encoded string using the `html()` function. Finally, we use the `text()` function to get the decoded string.

The output of the above code will be:

This is an encoded string.
 

Method 2: Using JavaScript

You can also use JavaScript to decode HTML entities. The `innerHTML` property of a DOM element can be used to decode the entities.

var encodedString = "
This is an encoded string.
"; var elem = document.createElement('div'); elem.innerHTML = encodedString; var decodedString = elem.textContent; console.log(decodedString); 

In the above code, we create a new `div` element using `document.createElement()`. We then set its `innerHTML` property to the encoded string. Finally, we use the `textContent` property to get the decoded string.

The output of the above code will be:

This is an encoded string. 

Conclusion

In this guide, we have explored two methods to decode HTML entities using jQuery and JavaScript. You can use either of these methods to easily decode HTML entities in your web applications.

How to decode html entities using jquery in Javascript?

When working with HTML content in Javascript, sometimes special characters like , &, etc., are represented as HTML entities, which can cause issues when trying to display or manipulate the content. To properly handle these characters, they need to be decoded back to their original form. This can be accomplished using jQuery, which provides a simple solution for decoding HTML entities. The following are several methods for decoding HTML entities in Javascript using jQuery:

Method 1: Using .html()

To decode HTML entities using jQuery’s .html() method, you can use the following code:

var encodedString = '<div>This is an encoded string.</div>'; var decodedString = $('
').html(encodedString).text(); console.log(decodedString); // Output: 
This is an encoded string.

This code creates a jQuery object with a div element, sets its HTML content to the encoded string using the .html() method, and then retrieves the decoded string using the .text() method.

Here’s another example that shows how to decode a string containing multiple HTML entities:

var encodedString = 'This & That <span>Here</span>'; var decodedString = $('').html(encodedString).text(); console.log(decodedString); // Output: This & That Here

In this example, the encoded string contains an ampersand entity ( & ) and a less-than entity ( < ), which are decoded to their respective characters.

Overall, using the .html() method with a jQuery object and then retrieving the decoded text using the .text() method is a simple and effective way to decode HTML entities in JavaScript.

Method 2: Using .text()

To decode HTML entities using jQuery, you can use the .text() method. Here’s how to do it in three simple steps:

var decodedEntity = $('').html(entity).text();

console.log(decodedEntity); // Output: 

Here’s another example that shows how to decode multiple entities at once:

var entities = ['<', '>', '&']; var decodedEntities = []; $.each(entities, function(i, entity)  decodedEntities.push($('').html(entity).text()); >); console.log(decodedEntities); // Output: ['', '&']

In this example, we use the $.each() method to loop through an array of HTML entities and decode each one using the .text() method. The decoded entities are then added to a new array, which is output to the console.

Overall, using the .text() method is a simple and effective way to decode HTML entities in JavaScript using jQuery.

Method 3: Using .parseHTML()

To decode HTML entities using jQuery, you can use the .parseHTML() method. Here are the steps to do it:

var encodedHtml = "<p>This is encoded HTML.</p>"; var $encoded = $("").html(encodedHtml);

var decodedNodes = $.parseHTML($encoded.html());

var decodedHtml = ""; $.each(decodedNodes, function(index, node)  decodedHtml += node.outerHTML || node.nodeValue; >);

var encodedHtml = "<p>This is encoded HTML.</p>"; var $encoded = $("").html(encodedHtml); var decodedNodes = $.parseHTML($encoded.html()); var decodedHtml = ""; $.each(decodedNodes, function(index, node)  decodedHtml += node.outerHTML || node.nodeValue; >); console.log(decodedHtml);

This code will output the decoded HTML string:

Method 4: Using .replace()

To decode HTML entities using jQuery with .replace(), you can use the following code:

var encodedString = "<div>Hello, World!</div>"; var decodedString = $("").html(encodedString).text();

This code creates a jQuery object with a div element and sets its HTML content to the encoded string. Then, the .text() method is used to get the decoded string.

Alternatively, you can use a regular expression with .replace() to replace each HTML entity with its decoded equivalent:

var encodedString = "<div>Hello, World!</div>"; var decodedString = encodedString.replace(/&/g, "&") .replace(/</g, ") .replace(/>/g, ">") .replace(/"/g, "\"") .replace(/'/g, "'");

This code uses multiple .replace() calls to replace each HTML entity with its decoded equivalent. The regular expression /&/g matches all occurrences of «&», and so on for the other entities.

In both cases, the result is the decoded string «Hello, World!».

What’s the right way to decode a string that has special HTML entities in it? [duplicate]

I’m not sure why that apostraphe is encoded like that ( ' ); all I know is that I want to decode it. Here’s one approach using jQuery that popped into my head:

This is my favourite way of decoding HTML characters. The advantage of using this code is that tags are also preserved.

Entity: Bad attempt at XSS: 

Ah, seems like basically the same approach I took but without the jQuery dependency (which is nice). Doesn’t it still seem hacky, though? Or should I be perfectly comfortable with it?

Oh wait, I get it: you’re using textarea specifically so that the tags are preserved (as you said) but HTML entities still get decoded. Pretty clever.

It’s acceptable. It’s the best way to decode HTML. No tags are passed, unlike your original solution, which parse (thus hide) tags.

Don’t use the DOM to do this if you care about legacy compatibility. Using the DOM to decode HTML entities (as suggested in the currently accepted answer) leads to differences in cross-browser results on non-modern browsers.

For a robust & deterministic solution that decodes character references according to the algorithm in the HTML Standard, use the he library. From its README:

he (for “HTML entities”) is a robust HTML entity encoder/decoder written in JavaScript. It supports all standardized named character references as per HTML, handles ambiguous ampersands and other edge cases just like a browser would, has an extensive test suite, and — contrary to many other JavaScript solutions — he handles astral Unicode symbols just fine. An online demo is available.

he.decode("We're unable to complete your request at this time."); → "We're unable to complete your request at this time." 

Disclaimer: I’m the author of the he library.

How to Decode HTML Entities Using Jquery

Security note: using this answer (preserved in its original form below) may introduce an XSS vulnerability into your application. You should not use this answer. Read lucascaro’s answer for an explanation of the vulnerabilities in this answer, and use the approach from either that answer or Mark Amery’s answer instead.

var encodedStr = "This is fun & stuff";
var decoded = $("").html(encodedStr).text();
console.log(decoded);

HTML Entity Decode

You could try something like:

var Title = $('').html("Chris' corner").text();console.log(Title);

Javascript decoding html entities

var text = '
name
ajde
da
';
var decoded = $('').html(text).text();
alert(decoded);

This sets the innerHTML of a new element (not appended to the page), causing jQuery to decode it into HTML, which is then pulled back out with .text().

jQuery (or JS) decodes HTML character entity in string

How do I prevent jQuery from decoding the HTML entity ‘ in the .append() operation?

jQuery is generating some HTML and then getting the browser to convert it to a DOM. It then appends that DOM fragment to the document DOM that represents the page.

When you examine the DOM using a DOM inspector (or when you use innerHTML to convert it to a string) you are serialising the DOM to HTML. At this point the browser does not know (because it hasn’t kept track, because it doesn’t need to) if the apostrophe in the DOM came from a literal apostrophe or a character reference for one. The algorithm it uses to decide how to represent the character uses the literal one (there is no point in it using a 5 character code when it can use 1 more readable character instead).

Joe’s CafeandJoe’s Cafeare two different ways of writing exactly the same thing in HTML. Which you get should not matter.

It may be the same thing in HTML but it is completely different when stored in a database.

It sounds like you want the form to submit the string Joe’s Cafe to the server.

Joe’s Cafewould not do that.

That would require: value=»Joe's Cafe»

Now you can achieve that by generating your DOM sanely instead of mashing strings together (because when you mash strings together, characters with special meaning in HTML get treated as having that special meaning).

$('#restaurant').append( 
$("").val(elem).text(elem)
);

however your implication is that having raw apostrophes in the data is breaking your SQL.

That means you are vulnerable to SQL injection attacks and that the real solution is to fix this server side.

See How can I prevent SQL-injection in PHP? or look up how to use prepared statements to prevent SQL injection in whatever programming language you are using on server.

How to Decode HTML Entities using Jquery/Javascript AutoComplete

Please choose one of these (but not both)

PHP Solution :

if you want to decode html entities you could first use php’s built-in html_​entity_​decode() function in autocomplete.php :

$dname_list = array();
while($row = mysqli_fetch_array($result))
 $dname_list[] = html_​entity_​decode($row['artist_name']);
>
echo json_encode($dname_list);

JS Solution :

jquery decode html entity µ

var content = $(this).val(".summary_description").html();

var content = $(this).val(".summary_description").text();

and it worked like a charm.
