conditional REGex pattern

Question

i retrive a text from a div with the following options : "1,000" $ OR "1,000.57" $ "20" OR "20.5"

i need to extract the number only ( int \ float) without the comma sign and without the dollar sign. as for now im using the following mask : /\d+/g;

but with this mask i get the number when it doesnt include comma and it get the number only to the decimal point ( e.g 290.5 -> 290 instead of it's original ) i'm looking for the correct regex mask for that so i will be able to parse the number after i get it .

Idk why your question is downvoted. this seems perfectly legit to me. — xdhmoore

so in short you want just the numbers with the decimals regardless how long but without letters (currency symbols) and without a comma separating the 1000 mark of the values? e.g "1,000" $ and "1,000.45867" $ to be 1000 and 1000.45867 respective? - will this div only take one value or will it take multiple values separated by something? — TrojanMorse

Ah, perhaps I misread the question. I thought you were trying to parse out that entire string, including quotes and ORs from a div. — xdhmoore

You could do it like this:

var str = ... // gets the text from the div
var num = Number(str.replace(/\$|,/g, '')); // converts the string to a number
                                            // (either a float or an int, depending
                                            // on the input string)

Yeah, regex is awesome! If you are looking for some resources, I used this website when I started learning. RegexOne is another cool resource with some interactive lessons.

I would probably do it in 2 steps. I would focus my regex on the quotation marks, something like /"[0-9,.$]"/g. I can't remember if you have to escape the . (like \.) inside []s. Then, after extracting the whole, original number, I would have other code to remove the comma, dollar sign, spaces, etc.
