How can I replace all occurrences of a dollar ($) with an underscore (_) in javascript?

Question

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(\'$

You don’t need to use RegExp. You can use the literal syntax:

str.replace(/\$/g, '_')

You just need to escape the $ character as it’s a special character in regular expressions that marks the end of the string.

Edit    Oh, you can also use split and join to solve this:

str.split("$").join("_")
