Question

我在textarea上应用ng-model，但它在ie 11中显示错误。我的代码如下。

＆＃xA;＆＃xA;

 ＆lt; div ng-隐藏= “DoctorDashboardCtrl.showEducation” ＆GT;＆＃XA; ＆lt; textarea placeholder =“2000 Characters Free flow text”width =“832px”height =“100px”class =“form-control”ng-model =“DoctorDashboardCtrl.otherdetails.education”＆gt;＆＃xA; ＆lt;！ -  {{DoctorDashboardCtrl.otherdetails.education}}  - ＆gt; ＆＃XA; ＆lt; / textarea＆gt;＆＃xA;＆lt; / div＆gt;＆＃xA;

＆＃xA;＆＃xA;

在ie11中将错误视为无效参数后。我将代码更改为

＆＃xA;＆＃xA;

 ＆lt; div ng-hide =“DoctorDashboardCtrl.showEducation”＆gt;＆＃xA; ＆lt; textarea placeholder =“2000个字符自由流文本”width =“832px”height =“100px”class =“form-control”ng-bind =“DoctorDashboardCtrl.otherdetails.education”＆gt; ＆＃XA; {{DoctorDashboardCtrl.otherdetails.education}}＆＃xA; ＆lt; / textarea＆gt;＆＃xA;＆lt; / div＆gt;＆＃xA;

＆＃xA;＆＃xA;

但现在，在我打印保存按钮后，我打印的值DoctorDashboardCtrl.otherdetails.education，它没有得到更新，而是显示旧值。有没有其他解决方案或我是否必须处理永远存在的错误？

@Gaurav：在代码中添加一个监视器，以便获得更新值

`$scope.$watch(
            function(){
                return $scope.otherdetails.education;
            },
            function(newValue, oldValue){
                if(newValue && newValue != oldValue) {
                    $scope.otherdetails.education = newValue;
                }
            },
            true
        );`

并在控制器启动时分配空数组和字符串：

$scope.otherdetails = []; $scope.otherdetails.education = "";

寻找ng-model的替代方案
