假设我在 AngularJS 中有一个控制器:

myApp.controller('SearchController',
    function ($scope, UserService) {

        // for intellisense, UserService is undefined here
        var user = UserService.getUsers().then(function(data){
                             // yada yada
                   }, function(err){
                             // yada yada
                   });
    });

但是,在我的智能感知文件中,我可以动态注入 UserService 以获取它的功能,如下所示:

intellisense.addEventListener('statementcompletion', function (event) {
    // tried doing this, but doesn't work!
    // event.target   = {};

    var injector   = angular.injector(['ng', 'myApp']);
    var dependency = injector.get(event.targetName);

    event.items    = [];
    for (method in dependency) {
        intellisense.logMessage(method);
        event.items.push({ name: method, kind: 'field', value: function () { } });
    }

});

UserService = {}现在,如果我在我的控制器函数中定义了一个全局变量(或函数变量),我输入UserService.的内容将弹出服务中的所有函数。但是,如果我没有定义它,因为它被undefinedintellisense 解释为,它无法向我显示选项,即使它statementcompletion正在工作(如 Javascript 语言服务控制台中所见)。

我的问题是,除了注释函数之外,是否有任何定义UserService为 intellisense 文件中的对象?定义event.target = {}不起作用(参见上面的智能感知代码)。

一种可行的方法是从带有空对象的智能感知代码中“调用”组件功能(控制器、服务等)。

我相信这会更干净,但这是我所做的:

references.js - 将此文件添加为工具>选项>文本编辑器>Javascript>智能感知>参考中的参考

    /// <reference path="../source/lib/assetBundle.js" />
    /// <reference path="_moduleDecorator.js" />
    /// <reference path="_componentDecorator.js" />
    /// <reference path="../source/app/appBundle.js" />

    intellisense.addEventListener('statementcompletion', function (event) {
    // for core angular objects
    addComponentToIntellisense('ng');
    // for custom objects in application modules
    for (var moduleIndex in modules) {
        addComponentToIntellisense(modules[moduleIndex]);
    }

    function addComponentToIntellisense(module) {
        var $injector = angular.injector(['ng', module]),
            dependency = $injector.get(event.targetName),
            dep;

        if (typeof dependency === "function") dep = new dependency();
        else dep = dependency;

        for (var method in dep) {
            event.items.push({ name: method, kind: 'field', value: dependency[method] });
        }
    }
});

_moduleDecorator.js - 跟踪应用程序中的所有模块

    //_moduleDecorator
    (function () {
    var originalModule = angular.module;
    // TODO change to array
    modules = {};
    var rep = false;
    var count = 0;
    angular.module = function () {
        for (var k in modules) {
            if (modules[k] === arguments[0]) {
                rep = true;
                break;
            }
        }
        if (!rep) modules[count++] = arguments[0];

        return originalModule.apply(angular, arguments);
    };
})();

_componentDecorator.js - 使用空对象参数“调用”组件函数

    (function () {
    // pick all the components in all modules and initialize them for intellisense
    for (var moduleIndex in modules) {
        var currentModule = angular.module(modules[moduleIndex]),
            queue = currentModule._invokeQueue,
            // add other components such as value, provider, etc later
            angularComponents = ['controller', 'factory', 'service', 'value'];

        for (var i = 0; i < angularComponents.length; i++) {
            var currentComponent    = angularComponents[i],
                originalComponentFn = currentModule[currentComponent];

            currentModule[currentComponent] = (function (currentModule, queue, originalComponentFn) {
                return function () {
                    originalComponentFn.apply(currentModule, arguments);
                    initializeComponents(queue);
                };
            })(currentModule, queue, originalComponentFn);
        }
    }

    function initializeComponents(queue) {
        var elem = queue.filter(function (element) {
            var componentName = element[2][0].toLowerCase();
            return (componentName.indexOf(componentName) !== -1);
        });

        for (var i = 0; i < elem.length; i++) {
            var tempComp = elem[i][2][1],
                compFunc;

            // for array notation for DI
            if (typeof tempComp !== "function") {
                compFunc = tempComp[tempComp.length - 1];
            } else {
                compFunc = tempComp;
            }

            // 10 parameter dependencies initialization for now
            compFunc({}, {}, {}, {}, {}, {}, {}, {}, {}, {});
        }
    }
})();
