You can create one main function like "init" and call other functions inside that function.
您可以创建一个像“init”这样的主函数，并在该函数内调用其他函数。
ng-init="init()"
from your controller
从您的控制器
function init() {
function1();
function2();
}

First of all, this should work, and probably the reason it doesn't is because you don't have these functions in the scope. Do you have an ng-controlleron this or ancestor element?
首先，这应该有效，可能它无效的原因是因为您在范围内没有这些功能。你有ng-controller这个或祖先元素吗？
If you do, make sure that these functions are defined on the scope:
如果这样做，请确保在范围内定义了这些函数：
.controller("MainCtrl", function($scope){
$scope.function1 = function(){...};
$scope.function2 = function(){...};
});
Second, you should not be using ng-initto call functions at all.
其次，您根本不应该使用ng-init来调用函数。
<div ng-controller="MainCtrl">
</div>
Instead, call these functions in the controller:
相反，在控制器中调用这些函数：
.controller("MainCtrl", function($scope){
function1();
function2();
function function1(){...};
function function2(){...};
});
From Angular documentation on ngInit:
The only appropriate use of ngInit is for aliasing special properties of ngRepeat, as seen in the demo below. Besides this case, you should use controllers rather than ngInit to initialize values on a scope.
ngInit 唯一合适的用途是为 ngRepeat 的特殊属性设置别名，如下面的演示所示。除了这种情况，您应该使用控制器而不是 ngInit 来初始化范围上的值。
