javascript having problems with regex

Question

having problems with regex in javascript.

need to parse out all variables from a String which include a letter.

As far i used /[0-9\][A-Za-z.]*/g gives me wrong results.

Sample:

windo.w029384-(2*I00983.size)+23.8/6+ss-t

need to parse out windo.w029384, I00983.size, ss, t

Thanks for help.

You can use:

'windo.w029384-(2*I00983.size)+23.8/6+ss-t'.match(/[a-z][\w.]*/ig);
//=> ["windo.w029384", "I00983.size", "ss", "t"]

I think /[a-z][\w.]*/ig would be more concise and better suited since variables can definitely use underscores and the OP is simply trying to detect variables. What about the alternate form of var.key, var["key"] or var['key'], or even var[key]?

Totally agree on \w but for other forms of input OP needs to specify more examples.

How about /[\w.]+/g? \w includes [0-9] and [A-Za-z]
