As the title states, I need to relace all occurrences of the $ sign in a string variable with an underscore.

I have tried:

str.replace(new RegExp('$', 'g'), '_');

But this doesn't work for me and nothing gets replaced.

The $ in RegExp is a special character, so you need to escape it with backslash.

new_str = str.replace(new RegExp('\$', 'g'), '_');

however, in JS you can use the simpler syntax

new_str = str.replace(/$/g, '_');
