我有一个类似以下内容的html:
<td>
<md-input-container>
<input type="text"
ng-focus="vm.service.disableSaveButton()"
ng-change="vm.service.disableSaveButton()"
ng-disabled="vm.service.isLocked"
aria-label="Travel Start"
ng-blur="vm.service.validateLine(itm, 1, 'TravelStartTime', $index, itm.TravelStartTime, true)"
ng-model="itm.TravelStartTime"
time-picker>
</md-input-container>
</td>
<td>
<md-input-container>
<input type="text"
ng-disabled="vm.service.isLocked"
aria-label="Job Start"
ng-focus="vm.service.disableSaveButton()"
ng-change="vm.service.disableSaveButton()"
ng-blur="vm.service.validateLine(itm, 2, 'JobStartTime', $index, itm.JobStartTime, true)"
ng-model="itm.JobStartTime"
ng-class="{'has-error': vm.service.isFieldValid(itm, 'JobStartTime')}"
time-picker>
</md-input-container>
</td>
</td>
我想知道是谁调用了validateLine方法,如果它是itm.TravelStartTime或itm.JobStartTime。如何在javascript中或尽可能使用angular.element做到这一点。
