来自控制器调用的 AngularJS 触发器指令 [英] AngularJS Trigger directive from controller call

问题描述

我想触发一个包含 jQuery 指令的 AngularJS 自定义指令.怎么做到呢?我在指令中阅读了关于发射函数的内容?

I want to trigger an AngularJS custom directive that contains jQuery instructions. How can it be done? I have read about emit function in the directive?

想法?

推荐答案

您可以使用服务在控制器和指令之间进行通信.

You can use a service to communicate between the controller and the directive.

服务可能如下所示:

app.service("directiveService", function() {
    var listeners = [];
    return {
        subscribe: function(callback) {
            listeners.push(callback);
        },
        publish: function(msg) {
            angular.forEach(listeners, function(value, key) {
                value(msg);
            });
        }
    };
});

指令可以响应服务:

app.directive("jQueryDirective", function(directiveService) {
    directiveService.subscribe(function(msg) {
        // pretend this is jQuery 
        document.getElementById("example")
        .innerHTML = msg;
    });
    return {
        restrict: 'E'        
    };
});

只需替换我为 jQuery 操作所做的一切，您就应该拥有所需的东西.

Just substitute what I did for jQuery manipulation and you should have what you need.
