add 2 comma separated string/value

tkm

Hello mates,
Can anyone please tell me how can I first convert two comma separated string into number and then add them in javascript? So I want to add 2 string like: 1,245+34,78,236

Any sample code would be greatly appreciated. Thank you.

What should be the result of your example, "1,245+34,78,236"?
1. The sum of 1 + 245 + 34 + 78 + 236
2. The sum of 1 + (245 + 34) + 78 + 236
3. The sum of 1245 + 3478236
4. None of the above

Thank you for the reply. I am actually looking for the solution of your 3, which is
3. The sum of 1245 + 3478236
Thank you.

Will it aways be
side A + side B
or Side A + Side B + Side C - Side D?
Your probably looking at regular expression here
I mean you can do a str.replace to take out the comas
and perhaps eval the remaining string assuming your operations are correct
that will allow for you to have the 4 basic math functions
