Input box can only enter the pure number + formatted input amount with the bank card JS code

HTML page code example:

< div class = "wrap" >    < input type = "text" id = "bankCard" placeholder = "输入银行卡号" > </ div >   < div class = "wrap" >    < input type = "text" id = "moneyNum" placeholder = "输入金额" > </ div > Format the bank card number (each four-bit sub-group) 　　　　$( "#bankCard" ).on( "keyup" , formatBC);  　　　 function formatBC(e){   $( this ).attr( "data-oral" , $( this ).val().replace(/\ +/g, "" ));        //$("#bankCard").attr("data-oral")获取未格式化的卡号   var self = $.trim(e.target.value);        var temp = this .value.replace(/\D/g, ‘‘ ).replace(/(....)(?=.)/g, ‘$1 ‘ );        if (self.length > 22){          this .value = self.substr(0, 22);          return this .value;        }        if (temp != this .value){          this .value = temp;        }      } formatted amount input (xxx,xxx.xx)   　　　  $( "#moneyNum" ).on( "keyup" , formatMN);   $( "#moneyNum" ).on({        focus: function (){          $( this ).attr( "data-fmt" ,$( this ).val()); //将当前值存入自定义属性        },        blur: function (){          var oldVal=$( this ).attr( "data-fmt" ); //获取原值          var newVal=$( this ).val(); //获取当前值          if (oldVal!=newVal) {            if (newVal == "" || isNaN(newVal)){              this .value = "" ;              return this .value;            }            var s = this .value;            var temp;              if (/.+(\..*\.|\-).*/.test(s)){              return ;            }            s = parseFloat((s + "" ).replace(/[^\d\.\-]/g, "" )).toFixed(2) + "" ;            var l = s.split( "." )[0].split( "" ).reverse(),                r = s.split( "." )[1];            t = "" ;            for (i = 0; i < l.length; i ++ ) {              t += l[i] + ((i + 1) % 3 == 0 && (i + 1) != l.length && (l[i+1]!= ‘-‘ )?
