javascript - AngularJS - Textarea 在 ng-click 后不想清除

Question

我的文本区域有问题。

当我想用 ng-click 清除她时，没有任何反应......

你能帮帮我吗？

这是我的代码，你可以用 Jsfiddle 测试:My app

如果你喜欢在这里看到它:

HTML:

<div ng-controller="Ctrl1">
        <div><textarea id="yourid" ng-model="isWriting" ng-change="writeEvent(isWriting)"></textarea>
        <span ng-if="displaySend == 1">Yann says :</span> {{isWriting}}
      <p ng-click="sendYaah(isWriting); isWriting == ''">YAH!</p>
</div>

JS:

$scope.writeEvent = function(isWriting) {

  $scope.imWriting = isWriting;
  var empty = "";

  if ($scope.imWriting != empty){
    $scope.displaySend = 1;
    // $scope.waitResponse = true;
  } else {
    $scope.displaySend = 0;
    // $scope.waitResponse = false;
  }

}

感谢帮助!

在 ng-click 中将 ==(equality operator) 更改为 =(assignment operator)

isWriting == ''

到

isWriting = ''
