HTML如下所示:
<select id="frontend-select" ng-model="tech.backEndValue"
ng-options="item.value as (item.name | translate) for item in techBackend">
</select>
这个输出是:
<select ng-model="tech.backEndValue" ng-options="item.value as (item.name | translate) for item in techBackend">
<option value="string:JAVA" label="Java" selected="selected">Java</option
<option value="string:PHP" label="PHP">PHP</option>
</select>
为什么值总是以值类型为前缀?
