Count the number of integers in a string

Question

how can I count the number of integers in a string using jQuery or javascript?

For example g66ghy7 = 3

Answer 1

The simplest solution would be to use a regular expression to replace all but the numeric values and pull out the length afterwards. Consider the following:

var s = 'g66ghy7'; 
alert(s.replace(/\D/g, '').length); //3
