Is it mobile no. validation

1 solution

assign x value with your number you want to validate.

C#
function test() {
       var x = '92385';
       if (isNumber(x))
           if (x.charAt(0) == '9') {
               alert("Success");
           }
   }
 function isNumber(n) {
        return !isNaN(parseFloat(n)) && isFinite(n);
    }
