Question

如何将焦点添加到新创建的字段？请参见目前为止的示例：http://jsfiddle.net/aERwc/165/

$scope.addField = function() {console.log('hi');
    $scope.fields[$scope.keyToAdd] = $scope.valueToAdd;
    $scope.setFieldKeys();
    $scope.keyToAdd = '';
    $scope.valueToAdd = '';
}

您可以使用此方法，但需要在ng-repeat中添加动画。见ng-repeat animation complete callback

基本上在回叫电话element.focus()

中

.animation('.repeat-animate', function () {
  return {
    enter: function (element, done) {
      element.hide().show(100, function(){
        var scope = element.scope();
        scope.$evalAsync(function(){ 
          element.find(':last')[0].focus();
        }); 
      });
    }
  };
});

对我来说，这似乎是最简单的方法：

Code Pen

<强> HTML

<html ng-app='app'>
  <body ng-controller='MainController as vm'>
    <input ng-repeat='thing in vm.things'>
    <hr />
    <button ng-click='vm.addThing()'>Add Thing</button>
  </body>
</html>

<强> JS

angular
  .module('app', [])
  .controller('MainController', MainController)
;

function MainController($timeout) {
  var vm = this;
  vm.things = [{}];
  vm.addThing = function() {
    vm.things.push({});
    $timeout(function() {
      // have to do this in a $timemout because
      // we want it to happen after the view is updated
      // with the newly added input
      angular
        .element(document.querySelectorAll('input'))
        .eq(-1)[0]
        .focus()
      ;
    }, 0);
  };
}

就个人而言，我实际上会使用jQuery并使代码更简单：

$('input:last').focus();

而不是：

angular
  .element(document.querySelectorAll('input'))
  .eq(-1)[0]
  .focus()
;

Angular - 将焦点放在动态创建的输入字段上
