Replace letters in a string with an underscore in javascript

Question

How do you replace every letter in a string with an underscore in javascript.

For example I would like the string of "name" to be replaced with _ _ _ _.

Is there a way I can specify letters a-z and replace it with an underscore.

Thanks in advance.

Simple,

str.replace(/[a-z]/g, '_')

to replace both upper and lowercase letters,

str.replace(/[a-z]/gi, '_')
