javascript - Angularjs：在指令中附加点击事件

Question

我在这里找到了一个很棒的树指令。原文：http: //jsfiddle.net/n8dPm/

我正在尝试附加点击处理程序。我将它添加到p元素中，如下所示，但它不起作用。怎么了：

代码http://jsfiddle.net/tHh5M/2/

module.directive("tree", function($compile) {
    return {
        restrict: "E",
        scope: {family: '='},
        template: 
            '<p ng-click="testme()">{{ family.name }}</p>'+
            '<ul>' + 
                '<li ng-repeat="child in family.children">' + 
                    '<tree family="child"></tree>' +
                '</li>' +
            '</ul>',
        compile: function(tElement, tAttr) {
            var contents = tElement.contents().remove();
            var compiledContents;
            return function(scope, iElement, iAttr) {
                if(!compiledContents) {
                    compiledContents = $compile(contents);
                }
                compiledContents(scope, function(clone, scope) {
                         iElement.append(clone); 
                });
            };
        },
        link: function (scope, elm, attrs) {
            scope.testme = function () {
                console.log('testme')
            };
        }
    };
});

您从编译函数返回的函数是链接函数。去掉 link 属性，将scope.testmeup 移到 compile 函数返回的函数中。

    compile: function (tElement, tAttr) {
        var contents = tElement.contents().remove();
        var compiledContents;
        return function (scope, iElement, iAttr) {
            if (!compiledContents) {
                compiledContents = $compile(contents);
            }
            compiledContents(scope, function (clone, scope) {
                iElement.append(clone);
            });
            scope.testme = function () {
                console.log('testme')
            };
        };
    }
