Can I escape html special chars in javascript?

Question

I want to display a text to HTML by a javascript function. How can I escape html special chars in JS? Is there an API ?

Answer 1

You can encode every character in your string:

function encode(e){return e.replace(/[^]/g,function(e){return"&#"+e.charCodeAt(0)+";"})}

Or just target the main characters to worry about (&, inebreaks, <, >, " and ') like:

function encode(r){
return r.replace(/[\x26\x0A\<>'"]/g,function(r){return"&#"+r.charCodeAt(0)+";"})
}

test.value=encode('How to encode\nonly html tags &<>\'" nice & fast!');

/*************
* \x26 is &ersand (it has to be first),
* \x0A is newline,
*************/
