I have tried var res = str.replace(/ |,|.|/g, ""); and var res = str.replace(/ |,|.|/gi, "");. What am I missing here?
var str = "Text with comma, space, and period."; var res = str.replace(/ |,|.|/g, ""); document.write(res);

If you just want to delete all spaces, commas and periods you can do it like that:
var res = str.replace(/[ ,.]/g, ""); You can also use the | operator, but in that case you have to escape the period, because a plain period will match with any character. As a general remark, if in a regular expression you have multiple alternatives with | that all consist of a single character, it is preferable to use a set with [...].

You need to escape dot \.:
"Text with comma, space and period.".replace(/ |,|\.|/g, "")

You can use these lines:
str = str.replace(/[ ,.]/g,''); Plus i have added a fiddle for this at Fiddle
