添加指令指令编程里面 [英] Adding directive inside the directive programatically

问题描述

我想我的指令的另一个实例追加到父的指令，但我不能用$申请重新编译我的指令。

I want to append another instance of my directive into the parent directive but i can't use $apply to recompile my directive.

我想我错过了什么这里的某个地方：）

I think i miss something here somewhere :)

我的HTML code

<div ng-app="TestApp">
    <div ng-controller="TestCtrl">
        <input ng-model="NewData" />
        <button ng-click="AddNewData($event)">Add New</button>
        <br /><br />
        <div test-collector="testColScope" id="testCol">
            <div test-data="" xx-value="Mouse" xx-href="https://fb.com"></div>
            <div test-data="" xx-value="Keyboard" xx-href="https://goo.gl"></div>
        </div>        
    </div>
</div>

我的JavaScript code

var app = angular.module('TestApp', []);

app.controller('TestCtrl', ['$scope', function($scope){   

    $scope.AddNewData = function($event){

        // i also want to access this but it shows undefined
      console.log("test-collector", $scope.testColScope);

      var div = $('<div></div>')
        .attr(
            {
                "test-data":"",
                "xx-value":$scope.NewData,
                "xx-href":"http://p.com"
            });       

        //$scope.$apply(function(){
            $('#testCol').append(div);  
        //});        
    };
}]);

app.directive("testCollector", function () {
    return {
        restrict: "A",
        scope: {

        },
        transclude: true,  
        replace: true,
        controller: function($scope) {
            console.log($scope);
        },
        link: function(scope, element, attrs) {
            console.log(attrs);
            scope[attrs.testCollector] = {
                Enteng : 'Dagpin'
            };
        },
        template: '<div>' +
                        '<ul><div ng-transclude></div></ul>' +
                   '</div>'
    }
});

app.directive("testData", function(){
    return {
        restrict: "A",
        require: '^testCollector',
        transclude: true,
        replace: true,
        scope: {
            xxValue: '@',
            xxHref: "@"
        },
        template: '<li><a href="{{xxHref}}">{{xxValue}}</a></li>'
    }
});

推荐答案

要了解角新元素已经插入你需要使用像 $编译服务第一编译元素 $编译（DIV）（$范围）那么只有你可以附加在角DOM该元素。

To understand angular new element has been inserted you need to first compile that element using $compile service like $compile(div)($scope) then only you can append that element in Angular DOM.

和您的指令已经上呈现的HTML，所以在div结构发生变化。

And you directive has already rendered on html, so the div structure is changed.

而不是做$（'＃testCol'）使用 angular.element（'＃testCol UL DIV'）

instead of doing $('#testCol') use angular.element('#testCol ul div')

根据@enzey DOM操作不应该内部控制完成。应该内部指令来完成。这就是为什么@Vincent＆安培;我在做小提琴的变化。
DOM操作的逻辑已经被移动到里面的指令。

As per @enzey DOM manipulation should not be done inside controller. It should be done inside directive. That's why @Vincent & I made the changes in fiddle. DOM manipulation logic has been moved to inside directive.
