How convert html code to char in javascript?

Question

There are a lot of chars converted to HTML entities in input parameters.

To use it, I need to convert the HTML entities to chars to make it readable.

How I can do it in JavaScript (interesting in be-directional convertion)?

examples:

html-code | char
-----------------
  a   |  a

Answer 1

You may try my code.

 var div=document.createElement("div"); div.innerHTML="a"; console.log(div.textContent);

Answer 2

Just remove the prefix ("&#") and suffix (";") and use String.fromCharCode .

 function entityToChar(ent){ return String.fromCharCode(ent.slice(2,-1)); } console.log(entityToChar("a"));

If you need to support arbitrary HTML entities, you can use the DOMParser API.

 function entityToChar(ent){ return new DOMParser().parseFromString(ent, "text/html").documentElement.textContent; } console.log(entityToChar("&"));

Use fromCharCode() . But you have to use only number. From your examples '&#97' just cut '&#' out and String.fromCharCode(97) .

Answer 4

You can use fromCharCode() for this

 var a = "a"; var b = String.fromCharCode(a.slice(2,-1)); console.log(b);
