Read a string and detect the first 8 numbers group

[Pedro Cortez Marques]

I want to pick a string information inside of a bigger string (file name or folder name)

The string I want to pick is a 8 digit number (next to each other) and it can be some where in the middle of  the big string.

For example:

Big string A:

_v_10097822-YVES.SAINT.LAURENT.273456YOD02.4176.Silk.15113

Big string B:

_v_nkld3sgrf10097822-YVES.SAINT.LAURENT.273456YOD02.4176.Silk.15113

I want to read always the 10097822

How can I do that with code in a function that returns the number I want?

You could try this..

var numberFromString = getNumbers("_v_nkld3sgrf10097822-YVES.SAINT.LAURENT.273456YOD02.4176.Silk.15113");
alert(numberFromString);
function getNumbers(str){
return str.match(/\d{8}/);
}
