i have created field(numeric percent field)

You can make a new Formula Rich Text field.

IF([my perecentage field name goes here] > 1, "Percentage must be less than 100%")

i enter more then 100 in one numeric percentage field,here error message is showing in rich text field. i want show error message in same field(where i enter more then 100 that field) 

That cannot be done natively.

This is the essential code:

$("#_fid_6").on("change", function() {
  if (_fid_6.value > 100) {
    alert("Please enter a value less than 100");
  } else if (_fid_6.value < 0) {
    alert("Please enter a value greater than 0");
  }
});
