[英]Decode HTML entities in JavaScript?
& -> `&`
> -> `>`
Any small library function that can handle this?任何可以处理这个的小型库函数?
I have on my utility belt this tiny function always:我的实用腰带上总是有这个小功能:
function htmlDecode(input){
var e = document.createElement('div');
e.innerHTML = input;
return e.childNodes[0].nodeValue;
}
htmlDecode("&"); // "&"
htmlDecode(">"); // ">"
It will work for all HTML Entities .它适用于所有HTML 实体。
Edit: Since you aren't in a DOM environment, I think you will have to do it by the "hard" way:编辑:由于您不在 DOM 环境中,我认为您必须通过“困难”的方式来做到这一点:
function htmlDecode (input) {
return input.replace(/&/g, "&")
.replace(/</g, "<")
.replace(/>/g, ">");
//...
}
If you don't like the chained replacements, you could build an object to store your entities, eg:如果您不喜欢链式替换,您可以构建一个对象来存储您的实体,例如:
function htmlDecode (input) {
var entities= {
"&": "&",
"<": "<",
">": ">"
//....
};
for (var prop in entities) {
if (entities.hasOwnProperty(prop)) {
input = input.replace(new RegExp(prop, "g"), entities[prop]);
}
}
return input;
}

he (for “HTML entities”) is a robust HTML entity encoder/decoder written in JavaScript. he (代表“HTML 实体”)是一个用 JavaScript 编写的强大的 HTML 实体编码器/解码器。 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.
它支持所有标准化的 HTML 命名字符引用, 像浏览器一样处理不明确的&符号和其他边缘情况,具有广泛的测试套件,并且——与许多其他 JavaScript 解决方案相反——他可以很好地处理星体 Unicode 符号。 An online demo is available.
