Question

我有一个下拉列表： -

<label>User Code:</label>
<select ng-options="c as c.User for c in userList"
    ng-model="selectedUser" id="search3">
</select>

此下拉列表中的数据来自API。我的指令代码： -

scope.getAllPeriodicities = function(){
    scope.userList = [];
    ApiServices.getAllPeriodicities().then(function (response) {
        scope.userList = response.data;
    });
}

scope.getAllPeriodicities();

有一个用户代码： - SS1234。我想在页面加载时选择此用户。我正在考虑使用selected属性，但不确定如何在获取的数据上使用它。

Answer 1

scope.getAllPeriodicities = function(){
  scope.userList = [];
    ApiServices.getAllPeriodicities().then(function (response) {
       scope.userList = response.data;
       scope.selectedUser = "SS1234";
   });
}
scope.getAllPeriodicities();

Answer 2

使用ng-model或ng-init

将您的默认值设为ng-value

<select ng-options="c as c.User for c in userList" ng-model="selectedUser" 
 id="search3" ng-value={{selectedUser = 'SS1234'}}></select>

//或

<select ng-options="c as c.User for c in userList" ng-model="selectedUser" 
 id="search3" ng-init="selectedUser = 'SS1234'"></select>

Answer 3

只需asign，def complexNumberMultiply(self, a, b): """ :type a: str :type b: str :rtype: str """ c,d = a.split('+') e,f = b.split('+') d = int(d[:-1]) f = int(f[:-1]) print c,d,e,f return '%s+%si' % (c * e - d * f, c * f + d * e)您想要的用户。

scope.selectedUser="SS1234"

Answer 4

在你的控制器中添加

$scope.selectedUser = 'SS1234';
