Question

我试图将两个变量从ngRepeat传递给一个函数，但似乎我错过了一些东西。有人可以解释它是什么吗？

-1

<tr  ng-repeat="user in users"><td>
<select
    ng-model="user.selection"
    ng-options="action.id as action.name for action in userActions"
    ng-change="actionChange(user.selection, user.id)"
    required>
</select></td></tr>

Answer 1

您应该从object

返回ng-options

<select
    ng-model="user.selection"
    ng-options="action as action.name for action in userActions"
    ng-change="actionChange(user)"
    required>
</select>

你错过了为功能和名字写名字并在范围内添加该功能。

$scope.actionChange =  function(user) {
    $log.log(user.name) // will display the selection
    $log.log(user.id) // is undefined
}

Demo Plunkr

ngRepeat参数进入ngChange函数
