Question

我正在选择md-like：

    <md-select ng-model="someModel" title={{someModel}}>
<md-option ng-value="opt.id" ng-repeat="opt in neighborhoods2">{{ opt.name }}</md-option>

它在title中显示了opt.id值。但我必须在title中显示opt.name。如何为所选值的名称添加title属性？

Answer 1

for that you have to select object in ng-value like 

     <md-select ng-model="someModel" title={{someModel.name}}>
    <md-option ng-value="opt" ng-repeat="opt in neighborhoods2">{{ opt.name }}</md-option>
</md-select>

but make sure in your controller you will get an object so you have to get id as

if(angular.isString(someModel)){
     var myValue= JSON.parse(someModel).id;
}

Answer 2

您可以使用opt.name对象本身作为值，而不是将值设置为opt。这样，您的md-select模型将具有所选项目的名称和ID。
