I have html tags need to be encoded.

<b>test</b>

I need to encode it to :

<b>test</b>

I am using escape, but it doesn't work.

document.write(escape("<b>test</b>"));

the result I got is

%3Cb%3Etest%3C/b%3E

this is not what I expected. is there another way to do html encode using javascript?

Answer 1

var html = "<b>test</b>";
var result = html.replace(/</g,"&lt;").replace(/>/g,"&gt;");
