Angular 指令的链接函数未被调用 [英] Angular directive's link function not being called

问题描述

我遇到了 AngularJS 指令链接函数的问题.它没有被调用，也不会抛出任何错误.指令返回中的模板也没有呈现:(应该是哪里出了问题?谢谢你的回答！

angular.module('sampleApp.game').directive('gameCanvas', function($injector) {console.log('指令正在运行');//这有效，功能链接Fn(范围，电子，属性){console.log('Link 函数不起作用 :(');//但这不是 :(};返回 {范围: {}，模板:'<div class="blabla"></div>',链接:linkFn}});

我的 html 模板文件

<h1>玩游戏！</h1><p>{{ 标语 }}</p><div class="game-canvas"></div>

解决方案

默认情况下，指令仅用于元素和属性 ('EA').将限制属性定义为C".最佳做法是始终明确定义它.

angular.module('sampleApp.game').directive('gameCanvas', function($injector) {console.log('指令正在运行');//这有效，功能链接Fn(范围，电子，属性){console.log('Link 函数不起作用 :(');//但这不是 :(};返回 {范围: {}，限制: 'C​​',//'EA' 默认模板:'<div class="blabla"></div>',链接:linkFn}

});

I've got a problem with AngularJS directive link function. It's not beeing called and it doesn't throw any error. Also the template in directive's return is not rendering :( Where should be problem? Thank you for answers!

angular.module('sampleApp.game').directive('gameCanvas', function($injector) {      
    console.log('Directive is working'); // this works,

    function linkFn(scope, ele, attrs) {
        console.log('Link function doesnt working :('); // but this not :(
    };

    return {
        scope: {},
        template: '<div class="blabla"></div>',
        link: linkFn
    }   
});

My html template file

<div class="jumbotron text-center">
    <h1>Play a game!</h1>
    <p>{{ tagline }}</p>   
    <div class="game-canvas"></div>
</div>

解决方案

By default, directives are for Element and Attribute ('EA') only. Define the restrict attribute as 'C'. Best practice is to always define it explicitly.

angular.module('sampleApp.game').directive('gameCanvas', function($injector) {      
console.log('Directive is working'); // this works,

function linkFn(scope, ele, attrs) {
    console.log('Link function doesnt working :('); // but this not :(
};

return {
    scope: {},
    restrict: 'C', //'EA' by default
    template: '<div class="blabla"></div>',
    link: linkFn
}   

});
