的間隔我有一個輸入字段如何檢查值屬於在JSON
<md-input-container ng-if="gpa.grade_type==2">
<input type="text" ng-model="gpa.grade_percent" aria-label="Grade">
</md-input-container>
我要檢查的gpa.grade_percent「percent_grade_from」：93 - 「percent_grade_to」：在JSON 96，值這個間隔適合 ，這樣我必須在下一個字段中顯示間隔相關的比例。
<td>
<span ng-bind="gpa.grade_scale"></span>
</td>
