Javascript how to return True if a variable called 'payroll_no' (20 long string) contains only numerics and false if it has any characters

Question

if  (!Character.isDigit(payroll_no))

{

   document.getElementById('field_117219').value ='We do not have your payroll number please email it to us')

}

else

 {

    Name = document.getElementById('field_115676').value;

    document.getElementById('field_117219').value ="Appraisal Details for "+Name;

     iframe_115667.location.replace('/sorce/apps/enh/asp/Appraisals.aspxgridname=Appraisals&Payroll_no='+Payroll_no);


}

It's best to actually ask a question, not just post code – Dave May 19 '15 at 15:47 — Dave, May 19 '15 at 15:47

You could apply a regex to it:

if (/^\d+$/.test(payrol_no)) {
    // Just digits
} else {
    // contains non-digit characters
}

Just use isNaN(payrol_no). It returns false if it is a number (hence the "is Not A Number"), and true otherwise.
