You should split string by ";" and then by ":". That's all!

how? i don't want to use for loop because...it may take time.
if i split by ";" i will get ID:2:B in first index after that
I will get dynamically ID:number by this i should get the option ie, A or B or C etc

Are you familiar with JQuery? Try JQuery.

for example:

var str="ID:1:A;ID:2:B;ID:3:A;ID:4:c;ID:5:D"
var result = str.Split(";")[0].Split[":"][2]

Not tested!

i think you are missing my point. or because of some poor explanation you are going in a wrong way

see I have got a value ID:2 based on this value i need have to get ID:2:B how can i filter this from original string?
