angular.js - Controller executed twice every time when changing route in angularjs?

Question

I am a beginner in angularjs. I encountered a problem recently during practice. After changing the route, the controller pointed to by the route is executed twice every time. Have you ever encountered such a problem? Let’s see what went wrong. .

Answer 1

A rough estimate is that you added ng-controller="controller you defined" to your html code

Answer 2

I have just used ng’s routing. In fact, in the routing configuration, we configured a controller for different templates. At this time, we no longer need to write it in the template

ng-controller

Answer 3

Looking at your html code, I guess you initialized the control twice somewhere.

Answer 4

Has the poster found the cause of this problem now? I have also encountered it. Please give me some advice.

Answer 5

<p class="dv_contain" ng-controller="controller"> This happened many times

Answer 6

I defined the controller once in $stateProvider, and then defined it again in html using ng-controller and controller as, and encountered the same situation. This can be solved by using controllerAs directly in $stateProvider.

Answer 7

Have your problem been solved? I also encountered this problem. I have only defined the controller in $stateProvider. I only need to switch it a few times and execute it several times. Each time it corresponds to a different $scope

Answer 8

Excuse me, if I don’t add ng-controller to my page, or should I use ng-click to execute it twice, it will jump twice? If I use ng-click, it will jump once

Answer 9

ng-view is written twice, just remove one and it will be fine
