问题描述
限时送ChatGPT账号..我正在编写一个包含许多自定义指令的网络应用程序.有没有办法查看每个模块已经注册的所有指令?
I am writing a web app with many custom directives. Is there a way to view all the directives that have been registered for each module?
推荐答案
模块有一个 _invokeQueue,它包含模块的内容.一个这样的函数:
Modules have an _invokeQueue, which contains the contents of the module. A function like this:
function Directives(module) {
var directives = [];
var invokes = angular.module(module)._invokeQueue;
for (var i in invokes) {
if (invokes[i][1] === "directive") directives.push(invokes[i][2]);
}
return directives;
}
将遍历模块并获取调用队列中标记为指令的每个元素.
will run through the module and grab each element in the invoke queue that are tagged as directives.
这是一个fiddle,您可以在其中玩它.
Here is a fiddle where you can play with it.
我把这个稍微通用一点,因为我不确定你想要哪种情况.
I made this slightly more generic, since I'm not sure which case you wanted.
由于模块可以包含其他模块,这将允许您递归地收集子模块中的指令.http://jsfiddle/V7BUw/2/.
Since modules can include other modules, this will allow you to recursively gather the directives that are in sub modules. http://jsfiddle/V7BUw/2/.
主要区别在于您还需要对 requires 数组中的每个模块重复:
the main difference is you need to repeat for every module in the requires array as well:
for (var j in module.requires) {
Directives(module.requires[j], directives);
}
希望这有帮助!
