Replace string containing $& in JavaScript regex

Question

I need to replace a html string with a dynamic value.This dynamic value(HTML encode) is to replace a pattern in the html string.

var htmlstring = \"

        

Answer 1

From Docs of replace, $& Inserts the matched substring.

You can use the replace callback to get the $& literal in the replaced string.

var htmlstring = "
{NAME}
";
var name = "$<Anonymous>" //Encoded form of "$";
var html = htmlstring.replace(/{NAME}/g, function(m) {
  return name;
});

console.log(html);
document.write(html);
