Let's say I have a string form-step-45. How to omit the form-step- and retrieve only the number using jQuery? The number varies and can be from 1 to ∞.

    Do you mean using JavaScript? There's no need to use jQuery for that. Is the `form-step-` constant? – BenM Oct 20 '14 at 15:19

    What's a likely and realistic upper bound for that number? If they get too large you're going to run into issues storing it in memory. – Anthony Grist Oct 20 '14 at 15:19

You can use match

 var num = "your-string-with-number-45".match(/\d+/)

var str = "form-step-45" ;
str = str.replace("form-step-" , "");

Try:

var final = 'form-step-45'.split('-');
final = final[2];

This should do it:

    var k = 'form-step-45';
    var num = k.split('-').pop();    


    var k = 'form-step-45';
    var num = k.split('-').pop();
    alert( num );

try this 

var str = "form-step-45" ;
str = str.replace("form-step-" , "");
