javascript - Prevent page postback when user hits enter -

i have web form when user hits enter, page posted back. here's thing: when user clicks on form, control focused (my mouse pointer changes 1 when click input control) , when enter hit, page reload.

is there way capture press of key not mattering user clicks on?

    //jquery example:     //bind keypress function of input tags  $("input").keypress(function (evt) {      //deterime our character code coming within event      var charcode = evt.charcode || evt.keycode;      if (charcode == 13) {      //enter key's keycode      return false;  }      });
