[英]In AngularyJs, why is my ng-model value not setting the selected option?
[英]Why my second ng-model does not return value as inserted?
我有這段代碼和textarea1和textarea2。 我的問題是我無法操縱textarea2上的ng-model
。
如果我在textarea2中進行了任何更改...什么都沒發生
有人可以幫我解決這個問題嗎? 謝謝。
您可能會看到我到目前為止完成的代碼。
var myApp = angular.module('myApp',[]); //myApp.directive('myDirective', function() {}); //myApp.factory('myService', function() {}); function MyCtrl($scope) { $scope.model1 = "Test1"; $scope.catch = function(model1) { $scope.model2 = model1; } }
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.1/angular.min.js"></script> <div ng-app="myApp"> <div ng-controller="MyCtrl"> Textarea 1 <textarea onkeypress="{{catch(model1)}}" ng-model="model1"></textarea> <br/> Text area 2 <textarea ng-model="model2"></textarea> <hr/> Textarea1: {{model1}} <br/> Textarea2: {{model2}} </div> </div>
您可以將onkeypress
更改為ng-change
嗎?
var myApp = angular.module('myApp',[]); //myApp.directive('myDirective', function() {}); //myApp.factory('myService', function() {}); function MyCtrl($scope) { $scope.model1 = "Test1"; $scope.catch = function(model1) { $scope.model2 = model1; } }
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.1/angular.min.js"></script> <div ng-app="myApp"> <div ng-controller="MyCtrl"> Textarea 1 <textarea ng-change="catch(model1)" ng-model="model1"></textarea> <br/> Text area 2 <textarea ng-model="model2"></textarea> <hr/> Textarea1: {{model1}} <br/> Textarea2: {{model2}} </div> </div>
