Javascript 获取Angularjs中ng按键上文本框的值

我想获得按键时文本框的值

我有类似的html代码

<input style="width: 20%; float: right;" 
       ng-model="que.SelectedOptionsUID" 
       type="text" 
       ng-keypress="myFunct($event)"/>

---

值位于下一项之后，表示将键入“a”，它将为空，然后键入“ab”，它将为“a”

$scope.myFunct = function (e) {
    var charCode = (e.which) ? e.which : e.keyCode;
    //i want here value of the textbox 
}

<input style="width: 20%; float: right;" 
       ng-model="que.SelectedOptionsUID" 
       type="text" 
       ng-keypress="myFunct($event, que.SelectedOptionsUID)"/>

$scope.myFunct = function (e, myValue) {
    var charCode = (e.which) ? e.which : e.keyCode;        
    // do something with myValue
}
