AngularJS/Javascript 下拉菜单 "onchange" 功能无效

AngularJS/Javascript dropdown "onchange" function is not working

<select name="Connection" class="mdl-button" id="dropConnection" onchange="connectionChange()" ></select> 

内容是从 JSON response.Thats 自动添加的,工作正常。

function connectionChange()
{
    var sel = document.getElementById("dropConnection");
    var connectionName = sel.options[sel.selectedIndex].text;
  $scope.connectionDetail = response.data.message.connectionDetailses.filter(det => det.connectionId === connectionName);
  console.log($scope.connectionDetail);
}

在 运行 页面之后,当我更改下拉内容时显示错误

home.html:265 Uncaught ReferenceError: $scope is not defined
    at connectionChange (home.html:265) // above javascript code.
    at HTMLSelectElement.onchange (VM4122 home.html:139)

查看此错误可以推断您没有在控制器中注入 $scope。在您的控制器中注入 $scope,它将解决此错误。
