jQuery global regex for replace with variable

Question

in the following example I am trying to replace all instances of the newname variable with -, however newname in my example is handled as text, rather than a as variable.

var newname = 'test';

var lastname = $(this).attr('name').replace(/newname/g, "-");

Can anyone help out?

Answer 1

var newname = 'test';
var regex = new RegExp(newname,"g")
var lastname = $(this).attr('name').replace(regex, "-");
