在脚本标签中访问Angular变量
[英]Access Angular variable within script tag
问题描述
I am making a web app:front-end in Angular and backend in Rails. 
我正在制作一个Web应用程序：Angular中的前端和Rails中的后端。 I am using LinkedIn's member profile plugin which shows person's profile based on URL being passed. 我正在使用LinkedIn的成员个人资料插件，该插件基于所传递的URL显示人员的个人资料。 Here is the code for this plugin. 这是此插件的代码。
<script src="//platform.linkedin.com/in.js" type="text/javascript"></script>
<script type="IN/MemberProfile" data-id="(Your LinkedIn URL)" data-format="inline" data-related="false"></script>
I want to make data-id part dynamic. 我想使data-id部分动态化。 Basically, I will let my users to write their linkedin address in text box and save it to Angular's variable. 基本上，我将让我的用户在文本框中写入他们的linkedin地址，并将其保存到Angular的变量中。 When the value changes, I want that value gets assigned to data-id . 当值更改时，我希望将该值分配给data-id 。 But I'm not sure whether data-id can access a variable in Angular. 但是我不确定data-id是否可以访问Angular中的变量。

Quite simple. 非常简单。 Create your app along with a global controller that will be initialised on your html tag like so: 创建一个应用程序以及将在html标记上初始化的全局控制器，如下所示：
<html ng-app="app" ng-controller="myctrl">
<head>
<script type="IN/MemberProfile" data-id="{{myId}}" data-format="inline" data-related="false"></script>
</head>
</html>
And have this as your controller and app initialisation, or something similar: 并将其作为您的控制器和应用程序初始化，或类似的操作：
var app = angular.module('app', []);
app.controller('myctrl', ['$scope', function($scope){
$scope.myId = 123;
}]);
To break it down, $scope.myId will be assigned the LinkedIn ID, and it is output on the page inside the head tag (I'm guessing that's where you want it) within the data-id attribute on the script tag. 要对其进行分解，将为$scope.myId分配LinkedIn标识，并在script标签的data-id属性内的head标签（我想是您想要的位置）内的页面上输出它。
