> Convert HTML entities to HTML characters, e.g. `>` converts to `>`.
|
|
|
|
## Install
|
|
|
|
Install with [npm](https://www.npmjs.com/):
|
|
|
|
```sh
|
|
$ npm install --save unescape
|
|
```
|
|
|
|
## Usage
|
|
|
|
```js
|
|
var decode = require('unescape');
|
|
|
|
console.log(decode('<div>abc</div>'));
|
|
//=> '<div>abc</div>'
|
|
|
|
// get the default entities directly
|
|
console.log(decode.chars);
|
|
```
|
|
|
|
## Characters
|
|
|
|
For performance, this library only handles the following common entities (split into groups for backward compatibility).
|
|
|
|
### Default entities
|
|
|
|
Only the following entities are converted by default.
|
|
|
|
| **Character** | **Description** | **Entity Name** | **Entity Number** |
|
|
| --- | --- | --- | --- |
|
|
| `<` | less than | `<` | `<` |
|
|
| `>` | greater than | `>` | `>` |
|
|
| `&` | ampersand | `&` | `&` |
|
|
| `"` | double quotation mark | `"` | `"` |
|
|
| `'` | single quotation mark (apostrophe) | `'` | `'` |
|
|
|
|
Get the default entities as an object:
|
|
|
|
```js
|
|
console.log(decode.chars);
|
|
```
|
|
|
|
### Extra entities
|
|
|
|
Only the following entities are converted when `'extras'` is passed as the second argument.
|
|
|
|
| **Character** | **Description** | **Entity Name** | **Entity Number** |
|
|
| `¢` | cent | `¢` | `¢` |
|
|
| `£` | pound | `£` | `£` |
|
|
| `¥` | yen | `¥` | `¥` |
|
|
| `€` | euro | `€` | `€` |
|
|
| `©` | copyright | `©` | `©` |
|
|
| `®` | registered trademark | `®` | `®` |
|
|
|
|
Example:
|
|
|
|
```js
|
|
// convert only the "extras" characters
|
|
decode(str, 'extras');
|
|
// get the object of `extras` characters
|
|
console.log(decode.extras);
|
|
```
|
|
|
|
### All entities
|
|
|
|
Convert both the defaults and extras:
|
|
|
|
```js
|
|
decode(str, 'all');
|
|
```
|
|
|
|
Get all entities as an object:
|
|
|
|
```js
|
|
console.log(decode.all);
|
|
```
