Javascript AngularJs：手动设置焦点以输入文本

我需要手动设置输入元素的焦点。我使用的是

$event.currentTarget.focus（）
HTML:

<div ng-repeat="item in items track by $index" ng-dblclick="onDblClick($event,item)">
      <input type="text" ng-model="item.id" ng-disabled="!item.editing" ng-blur="onBlur(item)">
    </div>

$scope.onDblClick = function($event, item) {
      item.editing = true;
      //setting the focus to elemnt but don't know why it's not working
      $event.currentTarget.focus();
    };

<div ng-repeat="item in items track by $index" ng-dblclick="onDblClick($event,item)">
      <input type="text" ng-model="item.id" ng-disabled="!item.editing" ng-blur="onBlur(item)" focus="item.editing">
    </div>

app.directive('focus', function($timeout) {
    return function(scope, elem, attrs) {
      console.log(attrs)
      scope.$watch(attrs.focus, function(newval) {
        if (newval) {
          $timeout(function() {
            elem[0].focus();
          }, 0, false);
        }
      });
    };
  });

这是你的电话号码
 无论如何，我是自己想出来的。我创建了一个指令
focus
，并设置了一个
$watch

HTML:

<div ng-repeat="item in items track by $index" ng-dblclick="onDblClick($event,item)">
      <input type="text" ng-model="item.id" ng-disabled="!item.editing" ng-blur="onBlur(item)">
    </div>

$scope.onDblClick = function($event, item) {
      item.editing = true;
      //setting the focus to elemnt but don't know why it's not working
      $event.currentTarget.focus();
    };

<div ng-repeat="item in items track by $index" ng-dblclick="onDblClick($event,item)">
      <input type="text" ng-model="item.id" ng-disabled="!item.editing" ng-blur="onBlur(item)" focus="item.editing">
    </div>

app.directive('focus', function($timeout) {
    return function(scope, elem, attrs) {
      console.log(attrs)
      scope.$watch(attrs.focus, function(newval) {
        if (newval) {
          $timeout(function() {
            elem[0].focus();
          }, 0, false);
        }
      });
    };
  });

这是。
它似乎在工作？您到底需要什么？它只是启用文本框，而不是聚焦文本框。如果双击时看到，则输入元素将被启用。但是如果你点击了enable input元素之外的任何地方，而不是理想情况下，它应该会失去焦点，ngBlur回调应该会被触发，但它不会发生。不管怎样，我误解了：）（编辑掉我写的内容）@klskl抱歉，我没有理解你。
