remove underscore from string

[rickburgen]

I need to remove a underscore(_) from a string, I am using the replace function bt it does not get removed? Does anybody know why.


here is the code

ISSUE_support = "Joe_Smith";
ISSUE_support.replace("_"," ");

ISSUE_support = "Joe_Smith";
ISSUE_support = ISSUE_support.replace("_"," ");

1. replace() is a method. You need to give your variable the new value with an assignment:

ISSUE_support = "Joe_Smith";
ISSUE_support=ISSUE_support.replace("_"," ");

2. On the other hand are you aware that the method, as you have written, will replace only the first occurrence of the underscore in the string? If you need multiple replacements, you must use a Regular Expression:

ISSUE_support=ISSUE_support.replace(/_/g," ");

Thanks for the second point.

The moment I have learned them, Regular Expressions changed my life

I have been playing around with regular expressions for sometime too. I use it with vim.

What I am concerned is http://www.w3schools.com/jsref/jsref_replace.asp doesn't even document that. I probably should default to https://developer.mozilla.org/en/Cor...String/replace but no browser compatibility list.

Oh, but it does, See Example 3 : "Perform a global, case-insensitive search [...] "

Yes, but would have been more useful in the description or definition. It is a bit unintuitive for me too - php and java both replace all occurrences.
