Try this
var yourStr = "Gem. Buitentemperatuur (etmaal)";
var newStr = yourStr.replace(/\s+/g, "_").replace(/\W+/g, "").toLowerCase();
//gem_buitentemperatuur_etmaal
.replace() is used to manipulate your string, a simple regular expression is passed to this and the value you want to replace it with
First we replace the Whitespace.
/ <- start the regex
\s <- match whitespace character
+ <- matches one or more times
/ <- end the regex.
And we replace this with your underscore .replace(/\s+/g, "_")
then find and match all non word characters.
/ <- start the regex
\W <- match all non word characters (everything but a-z, A-Z, 0-9 and _)
+ <- matches one or more times
/ <- end the regex
This part looks like this .replace(/\W+/g, "")
the g after the closing / stands for global to look all along the string and not just for the first match.
Here's a fiddle

"Gem. Buitentemperatuur (etmaal)".toLowerCase().replace(/[^a-z]+(?!$)/g, "_").replace(/^[^a-z]|[^a-z]$/, "");

try this
function escapeRegExp(str) {
return str.replace(/[\-\[\]\/\{\}\(\)\*\+\?\.\\\^\$\|]/g, "\\$&");
}
function replaceAll(find, replace, str) {
return str.replace(new RegExp(escapeRegExp(find), 'g'), replace);
}

You can use:
s="Gem. Buitentemperatuur (etmaal)";
s.toLowerCase().replace(/ +/g, '_').replace(/\W+/g, '');
//=> "gem_buitentemperatuur_etmaal"

Use this:
[^\w]+
And .replace() with _.
Working example: http://regex101.com/r/nN9pX7
var str = "Gem. Buitentemperatuur (etmaal)";
str.replace(/\W+/g, "_").toLowerCase().replace(/(^_|_$)/, "");
