angularJS textarea-textarea不显示文本

Question

I have this textarea

<textarea ng-model="textArea" ng-change="update(data.id,textArea)" style="height:120px; width:200px;">{{data.description}}</textarea>

when i run it the html code is:

<textarea ng-model="textArea" ng-change="update(data.id,textArea)" style="height:120px; width:200px;" class="ng-pristine ng-valid ng-binding">my test 123</textarea>

nothing strange except that i don't see the text on the textarea in the page..... some ideas??

Answer 1

That doesn't make sense. The current value of textarea comes from databinding ( ng-model ).

<textarea ng-model="textArea" ng-change="update(data.id,texArea)" 
       style="height:120px; width:200px;"></textarea>

in your controller, use $scope.textArea = 'YOURVALUE';

Alternatively you can set up "double binding" in controller, such as:

$scope.$watch('data.description', function(newValue){
  $scope.textArea = newValue;
});

ps, you have TYPO whe trying to spell " textArea ", you've spelt it as " texArea ".
