What is the best way, when hitting enter inside a form, the focus to go to the next input instead submitting the form with angularjs.

I have a form with a lot of fi

    This is the directive I ended up with (thanks to Zack Argyle):

    
        
        angular.module('myApp').directive("nextFocus", nextFocus);
    
        /** Usage:
          <input next-focus id="field1">
          <input next-focus id="field2">
          <input id="field3">
          Upon pressing ENTER key the directive will switch focus to
          the next field id e.g field2
          The last field should not have next-focus directive to avoid
          focusing on non-existing element.
          Works for Web, iOS (Go button) & Android (Next button) browsers, 
        **/
    
        function nextFocus() {
          var directive = {
            restrict: 'A',
            link: function(scope, elem, attrs) {
              elem.bind('keydown', function(e) {
                var partsId = attrs.id.match(/field(\d{1})/);
                var currentId = parseInt(partsId[1]);
    
                var code = e.keyCode || e.which;
                if (code === 13) {
                  e.preventDefault();
                  document.querySelector('#field' + (currentId + 1)).focus();
                }
              });
            }
          };
          return directive;
    
        }

      $scope.moveFocus = function (nextId,prevId,downId,upId,index,event) {
                debugger;
                if (event.keyCode == 39) {
                    nextId = nextId + index;
                    $('#' + nextId).focus();
                }
                else if(event.keyCode == 37)
                {
                    prevId = prevId + index;
                    $('#' + prevId).focus();
                }
                else if(event.keyCode == 38)
                {
                    upId = upId + (index - 1);
                    $('#' + upId).focus();
                }
                else if(event.keyCode == 40)
                {
                    downId = downId + (index + 1);
                    $('#' + downId).focus();
                }
                else if(event.keyCode==13)
                {
                    if (nextId == "desc") {
                        nextId = "quantity" + index;
                        $('#' + nextId).focus();
                    }
                    else if(nextId == "uom")
                    {
                        nextId = "stkid" + (index + 1);
                        $('#' + nextId).focus();

    Based on the answer by wolcy97 but using only angular

     /** Usage:
      <input next-focus tabindex="0">
      <input next-focus tabindex="1">
      <input tabindex="2">
      Upon pressing ENTER key the directive will switch focus to
      the next tabindex.
      The last field should not have next-focus directive to avoid
      focusing on non-existing element.
      Works for Web, iOS (Go button) & Android (Next button) browsers, 
    **/ 
     app.directive('nextFocus', [function() {
      return {
        restrict: 'A',
        link: function(scope, elem, attrs) {
          elem.bind('keydown', function(e) {
            var code = e.keyCode || e.which;
            if (code === 13) {
              e.preventDefault();
              try {
                if (attrs.tabindex !== undefined) {
                  var currentTabeIndex = attrs.tabindex;
                  var nextTabIndex = parseInt(currentTabeIndex) + 1;
                  var elems = document.querySelectorAll("[tabindex]");
                  for (var i = 0, len = elems.length; i < len; i++) {
                    var el = angular.element(elems[i]);
                    var idx = parseInt(el.attr('tabindex'));
                    if (idx === nextTabIndex) {
                      elems[i].focus();
                      break;
                    }
                  }
                }
              } catch (e) {
                console.log('Focus error: ' + e);
              }
            }
          });
        }
      };
    }]);

    I suggest making a custom directive. Something like this. I haven't tested this.

    .directive('focus', function() {
      return {
        restrict: 'A',
        link: function($scope,elem,attrs) {
    
          elem.bind('keydown', function(e) {
            var code = e.keyCode || e.which;
            if (code === 13) {
              e.preventDefault();
              elem.next().focus();
            }
          });
        }
      }
    });
    

    Something like that should work. You might have to tweek something. Good luck.

    On Enter press it moves to next element of DOM, but element requires id to set focus

    starter.directive('focustonext', function () {
    return {
        restrict: 'A',
        link: function ($scope, selem, attrs) {
            selem.bind('keydown', function (e) {
                var code = e.keyCode || e.which;
                if (code === 13) {
                    e.preventDefault();
                    var pageElems = document.querySelectorAll('input, select, textarea'),
                        elem = e.srcElement || e.target,
                        focusNext = false,
                        len = pageElems.length;
                    for (var i = 0; i < len; i++) {
                        var pe = pageElems[i];
                        if (focusNext) {
                            if (pe.style.display !== 'none') {                               
                                document.getElementById(pe.id).focus();
                                break;
                            }
                        } else if (pe === elem) {
                            focusNext = true;
                        }
                    }
                }
            });
        }
       }
    });
    

    Thanks all..
