A lot of people will tell you you shouldn't do this (as mentioned in the docs here: https://docs.angularjs.org/api/ng/directive/ngInit).
很多人会告诉您不应该这样做（如此处的文档中所述：https: //docs.angularjs.org/api/ng/directive/ngInit）。
As for actually doing it....
至于实际做....
<div ng-controller="controller" ng-init="x = x">

也许这个可以帮助你：

If you want to execute a function on a tag where you have a controller, why not simply run the function in the controller's constructor (i.e. function)?
如果要在具有控制器的标签上执行函数，为什么不简单地在控制器的构造函数（即函数）中运行该函数？
Not everything has to be in the markup.
并非所有内容都必须在标记中。
JS:
JS：
angular.module(...).controller('MyController', function ($scope) {
$scope.myFunction($scope.x);
})
HTML:
HTML：
<div ng-controller="MyController"></div>
