angularjs – 如何在角度js材质设计中动态启用或禁用输入字段

我遇到了ng-disable的问题.因为我使用棱角分明的材料我觉得这不起作用.我希望根据条件动态禁用或启用输入框.

注意： – 我有多个输入字段我想要禁用或一次性启用所有输入.

我这样想

<md-input-container class="md-block" flex-gt-sm>
    <label for="Autocomplete">From</label>
    <input required type="text" class = "hideShadow" ng-model="FromLOCATIOn"
           uib-typeahead="state for state in states | filter:$viewValue | limitTo:8" 
          class="form-control" ng-disabled="isDisabled">
    <div ng-messages="searchFlight.FromLOCATIOn.$error">
    <div ng-message="required">Please enter from LOCATIOn</div>
     </div>
</md-input-container>

我试图像这样动态访问ng-disabled =“isDisabled”

$scope.isDisabled = true;

但这不起作用.我可以知道我哪里错了吗？

$scope.model = {
    isDisabled: true
};

ng-disabled="model.isDisabled"
