Question

这里我试图将ticketPrice（ng-model）和selceted numberOfTickets（ng-model）相乘，但我总是得到NAN总数

<tr>
     <td ng-model="ticketPrice">5</td>
     <td>
       <select class="form-control" ng-model="numberOfTickets" 
            ng-options="n for n in [] | range:1:15"  >
           <option value="">--Select No. of Tickets--</option>                                                    
       </select>
     </td>
     <td class="text-primary text-center"><strong ng-model="ticketsTotalPrice">{{ ticketPrice * numberOfTickets }} </strong></td>
    </tr>

请提供解决方案

谢谢！

Answer 2

使用ng-bind not ng-model

<strong ng-bind="ticketPrice * numberOfTickets"></strong>

在角度js中将字符串转换为int
