The examples in this article describe how to resolve conflicts between template views and AngularJS. Share it with everyone for your reference, the details are as follows:

Problem:

In the mvc view of php, we need to

pass some data to the template during the loading process:

For example:

Here is a controller

$data['users'] = {something from databases};
$this->load->view('home/index',$data);
Copy after login

Here is the corresponding view

<div ng-controller="loadData">
   <ul>
    <!--1. 初始化的时候我们需要使用下面这句-->
    <?php foreach(users as user):?>
    <li><?=$user->name?>:<?=$user->email?><li>
    <?php endforeach?>
    <!--2. 但是结束后 我们需要使用这句 通过ajax 更新 -->
    <li ng-repeat="user in users">{{user.name}}:{{user.email}}</li>
  </ul>
</div>
Copy after login

So now the question is how to deal with the contradiction between 1 and 2?

The first solution:

<script>
 var usersPrefetch = [
  <?php foreach(users as user):?>
  {"name": "<?=$user->name?>", "email": "<?=$user->email?>"},
  <?php endforeach?>
 ];
</script>
Copy after login

We store the data passed by php in variables, and then assign it through
$scope, ok

The second solution (recommended):

We use the ng-if attribute to solve our problem, calling php data when users is undefined
After the ajax transfer is completed, use our data and define $scope.users

<ul ng-if="!users">
 <?php foreach(users as user):?>
 <li><?=$user->name?>:<?=$user->email?><li>
 <?php endforeach?>
</ul>
<ul ng-if="users">
 <li ng-repeat="user in users">{{user.name}}:{{user.email}}</li>
</ul>
Copy after login
