AngularJS 指令中的 locals 代表什么

问题描述

AFAIK 这没有记录在案，但我在 angular 源代码中发现了一个指令示例中的 locals 属性:

AFAIK this is not documented, but I found in angular source a locals attribute in a directive example:

angular.module('transclude', [])
          .directive('pane', function(){
             return {
               restrict: 'E',
               transclude: true,
               scope: 'isolate',
               locals: { title:'bind' },
               template: '<div style="border: 1px solid black;">' +
                           '<div style="background-color: gray">{{title}}</div>' +
                           '<div ng-transclude></div>' +
                         '</div>'
             };
         });

它有什么作用?我该如何使用它?

What does it do? How can I use it?

更准确地说:

如何从directive的控制器或linking函数访问locals?

How can I access locals from directive's controller or linking function?

如何从directive的控制器或linking函数动态更改locals?

How can I dynamicly change locals from directive's controller or linking function?

我可以在每个指令中使用 locals 还是必须是一个带有 transclude=true 的指令?

Can I use locals in every directive, or does it have to be a directive with a transclude=true ?

推荐答案

我只想结束这个问题.所以答案就像@ArunPJohny 所说的

I just want to close this question.So the answer is like @ArunPJohny said

@param {Object=} locals(可选对象).

@param {Object=} locals (Optional object).

如果预置，则在查询 $injector 之前，首先从该对象读取任何参数名称

If preset then any argument names are read from this object first, before the $injector is consulted
