angular.js - select如何根据参数显示相应的选项

Question

我的代码如下：

<select ng-model="testV" ng-change="change()">
      <option value="">Any</option>
      <option value="0">0</option>
      <option value="1">1</option>
      <option value="2">2</option>
</select>

如何让selected的选项设置为value等于$scope.testV的项呢？

Answer 1

Add this sentence$scope.testV = 2; to the controller and it will display 2 by default.

$scope.change = function(){
    console.log($scope.testV);
}

In this way, every time the select value is changed, the console will output the changed value.
