当 gn-model 为真时如何将注意力转移到输入上？

Question

我有 div 对象和输入字段，它们放置在隐藏表单中。当我点击 div 时，表格显示并且焦点必须移动到输入字段。

<div ng-click="createForm = true">
    Create item
</div>

<div ng-show="createForm">
    <form class="form-horizontal">
        <div class="input-group">
            <input type="text" ng-blur="createForm = false">
        </div>
    </form>
</div>

我找到了使用指令的解决方案，但它不起作用。

app.directive('focusOn', function() {
    return function(scope, elem, attr) {
        scope.$on(true, function(e){
            elem[0].focus();
        });
        scope.$on(attr.focusOn, function(e) {
            elem[0].focus();
        });
    };
});

您还没有应用该指令？

<input type="text" ng-blur="createForm = false" focus-on="createForm">

参见 this JSFiddle

HTML

<div ng-app="myApp" ng-controller="myController">
    <div ng-click="createForm = true">
        Create item
    </div>

    <div ng-show="createForm">
        <form class="form-horizontal">
            <div class="input-group">
                <input type="text" ng-blur="createForm = false" focus-on="createForm">
            </div>
        </form>
    </div>
</div>

JavaScript

var app = angular.module("myApp", []);

app.directive('focusOn', function() {
    return {
        limit: 'A',
        scope: {
            focusOn: "="
        },
        link: function(scope, elem, attr) {
            scope.$watch("focusOn", function(e){
                elem[0].focus();
            });
        }
    }
});

app.controller("myController", ["$scope", function($scope){
    $scope.createForm = false;
}]);
