jquery only allow input float number

Question

i\'m making some input mask that allows only float number. But current problem is I can\'t check if multiple dots entered. Can you check those dots and prevent it for me?

Answer 1

Below Code I am allowing only Digits and Dot symbol.
ASCII characters number starts in 47 and ends with 58 and dot value is 190.

   $("#Experince").keyup(function (event) {
        debugger

        if ((event.which > 47
            && event.which < 58) ||event.which== 190) {
             if ($("#Experince").val().length > 3) {

        }
        } // prevent if not number/dot
        else {
             $("#Experince").val($("#Experince").val().slice(0, -1))
        }

    });
