Javascript html decode

HTML entity names are case sensitive. This table shows a list of reserved HTML entities with their associated character and description. Most programming languages provide a way to convert HTML entities to their associated character and vice-versa. This function is identical to htmlspecialchars in all ways, except with htmlentitiesall characters which have HTML character entity equivalents are translated into these entities.

The purpose of a character entity reference is to provide a way to refer to a character that is not universally encodable.

Skip intro and go straight to the HTML encoder and decoder tool! One of the things that I have found strange about Javascript is its lack of inbuilt functions to handle HTML encoding and decoding. For more details about reformating content with Javascript and the problems associated with simple replace statements you can read my related blog article. Therefore I have created a little library of functions designed to help me encode and decode HTML with Javascript which you can download here: Encoder.

I have defaulted the entry box with some example content and then encoded it and then decoded the result to prove the decoding works. Obviously if you don't mind about double encoding then call Encoder.

This is my favourite way of decoding HTML characters.

The advantage of using this code is that tags are also preserved. It supports all standardized named character references as per HTMLhandles ambiguous ampersands and other edge cases just like a browser wouldhas an extensive test suite, and — contrary to many other JavaScript solutions — he handles astral Unicode symbols just fine. An online demo is available. See this Stack Overflow answer for some more info.

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.

Excess bits shifted off to the right are discarded.

Copies of the leftmost bit are shifted in from the left. Since the new leftmost bit has the same value as the previous leftmost bit, the sign bit the leftmost bit does not change. Hence the name "sign-propagating". Zero bits are shifted in from the left. The sign bit becomes 0, so the result is always non-negative. Unlike the other bitwise operators, zero-fill right shift returns an unsigned bit integer. Learn the best of web development Get the latest and greatest from MDN delivered straight to your inbox.

For worldwide interoperability, URIs have to be encoded uniformly. To map the wide range of characters used worldwide into the 60 or so allowed characters in a URI, a two-step process is used:. The two hexadecimal digits of the triplet s represent the numeric value of the replaced character. Therefore, the term percent-encoding should be preferred. The characters allowed in a URI are either reserved or unreserved or a percent character as part of a percent-encoding.

Reserved characters are those characters that sometimes have special meaning, while unreserved characters have no such meaning.

Using percent-encoding, characters which otherwise would not be allowed are represented using allowed characters. The sets of reserved and unreserved characters and the circumstances under which certain reserved characters have special meaning have changed slightly with each revision of specifications that govern URIs and URI schemes.

Any other characters are not allowed in a URL. The unreserved characters can be encoded, but should not be encoded. The reserved characters have to be encoded only under certain circumstances.

The reserved characters are:! As URL encoding involves a pair of hexadecimal digits and as a pair of hexadecimal digits is equivalent to 8 bits, it would theoretically be possible to use one of the 8-bit code pages for non-ASCII characters e. ISO for umlauts. On the other hand, as many languages have their own 8-bit code page, handling all these different 8-bit code pages would be a quite cumbersome thing to do.

Some languages do not even fit into an 8-bit code page e. In addition, the CGI specification contains rules for how web servers decode data of this type and make it available to applications.

This, in turn, prevents the rendering of the next frame after adding the image to the DOM from causing a delay while the image loads. A Promise which is resolved once the image data is ready to be used. One potential use case for decode : when loading very large images for example, in an online photo albumyou can present a low resolution thumbnail image initially and then replace that image with the full-resolution image by instantiating a new HTMLImageElementsetting its source to the full-resolution image's URL, then using decode to get a promise which is resolved once the full-resolution image is ready for use.

At that time, you can then replace the low-resolution image with the full-resolution one that's now available.

The following example shows how to use the decode method to control when an image is appended to the DOM. Without a Promise -returning method, you would add the image to the DOM in a load event handler, such as by using the img. Get the latest and greatest from MDN delivered straight to your inbox.
