我有一个JSON对象PayheadsEmpMap数组，在这里我有empData，并且我有一些员工数据。每位员工都附上一份PayRoll信息。这包含OnetimeData。这整个结构重演。我使用了PayHeadData.payHeadValue作为ng-model（同样的结构重复了很多次）。
现在的问题是，当我在PayHeadEmpMap中重复多个元素时，ng-model的值对一个员工填充，在下一个相同的索引上填充，所以ng-repeat。
我希望ng-model具有独特的价值。
<div ng-repeat="payheademp in PayheadsEmpMap" my-users-post-menu-creation-directive>
<div class="toHideAll" id="idOfDataDiv_{{payheademp.ph_id}}" ><!-- ng-show="showDiv($index,payheademp.ph_id)" -->
<table style="width:100%">
<tbody >
<tr ng-repeat='employee in payheademp.empData'>
<td class="row-label" style="width:60%;text-align:left">
<span ><span class="BodyTxt3Bold">{{employee.fname + " " }}{{employee.mname + " "}}{{employee.lname}} </span>({{employee.gen_id}}){{", "+employee.employee_designation}}{{", "+employee.location_name}}</span>
</td>
<td ng-repeat="OneTimeData in employee.PayHeadData" class="row-label" style="width:40%;text-align:left;vertical-align:top">
<input ng-model="OneTimeData.payHeadaValue" style="float:left" id=idOfInp_{{OneTimeData.payheadId}}_{{employee.employee_id}} type="text" onkeyup="checkForInput(this);" class="W4_Normal V3 two-decimals">
</td>
</tr>
</tbody>
</table>
