javascript - 触发点击 angular.js 中的 html 元素

Question

我目前有一个指令。当我单击带有“点击编辑”指令的元素时，会显示一个文本字段以编辑内容。

我希望当我单击按钮时，此行为继续发生。我需要当单击按钮时，相当于单击指令。我怎样才能实现这个目标？

    <label>Sprint name:</label> <div click-to-edit type="inputText" ng-model="sprintName"></div>
    <br/>
    <input type='button' value='trigger Directive' ng-click='triggerDirective()'>
   </div>

Answer 1

要实现您必须做的事情，您可以使用 angular events或you can share an object through isolate scope and add a function to it 。

示例:

1- 使用 Angularjs 事件: ( PLUNKER )

HTML:

<div click-to-edit></div>
<button type="button" ng-click="item.toggle()">Toggle from Controller</button>

Controller :

app.controller('MainCtrl', function($scope) {
    $scope.toggle = function(){
        //Emit the event
        $scope.$broadcast('app.myEvent');
    };
});

指令:

app.directive('clickToEdit', function() {
    return {
        restrict: 'A',
        template: `
            <div ng-show="editState">
                <div>
                    <input type="text"/>
                    <button type="button" ng-click="item.toggle()">Cancel</button>
                </div>
            </div>
        `,
        link: function (scope, element, attrs) {
            scope.editState = false;

            scope.toggle = function () {
                scope.editState = !scope.editState;
            }

            //Listen and handler the event
            scope.$on('app.myEvent', function(event){
                scope.toggle();
            });
        }
    }
});

2- 通过隔离范围共享对象: ( PLUNKER )

HTML:

<div click-to-edit item="item"></div>
<button type="button" ng-click="item.toggle()">Toggle from Controller</button>

Controller :

app.controller('MainCtrl', function($scope) {
    $scope.item = {};
});

指令:

app.directive('clickToEdit', function() {
    return {
        restrict: 'A',
        scope: {
            item: '='
        }
        template: `
            <div ng-show="editState">
                <div>
                    <input type="text"/>
                    <button type="button" ng-click="item.toggle()">Cancel</button>
                </div>
            </div>
        `,
        link: function (scope, element, attrs) {
            scope.editState = false;

            //Here you add the function to the isolate scope 'item' variable
            scope.item.toggle = function () {
                scope.editState = !scope.editState;
            }
        }
    }
});
