请明确@ZsoltGyöngyösi给出的答案:

Just to be clear with the answer @ZsoltGyöngyösi gave:

每个具有 id 字段的元素都需要 ng-model ="$ parent.row.field"

因此，如果您通过以下方式设置 queryRowTemplate.hml ，则会删除正确的行:

Thus, the correct row will be deleted if you setup queryRowTemplate.hml this way:

<div class="form-group col-md-3">
  <label for="selectedField">Select Field</label>
  <select id="selectedField" class="form-control" ng-model="$parent.row.field">
    <option>title</option>
    <option>application</option>
    <option>subject</option>
    <option>filetype</option>
  </select>
</div>
<div class="form-group col-md-3">
  <label for="logicalOperator">Logical Operator</label>
  <select id="logicalOperator" class="form-control" ng-model="$parent.row.logical">
    <option>equal to</option>
    <option>not equal to</option>
  </select>
</div>
<div class="form-group col-md-3">
  <label for="searchText">Search</label>
  <input id="searchText" class="form-control" type="text" placeholder="search..." ng-model="$parent.row.search" />
</div>
<div class="form-group col-md-3">
  <label for="operator">Operator (optional)</label>
  <select id="operator" class="form-control" ng-model="$parent.row.operator">
    <option value=""></option>
    <option>AND</option>
    <option>OR</option>
  </select>
</div>
<button class="btn btn-default" ng-click="addRqst()" type="submit">Add Row</button>
<button class="btn btn-default" ng-click="removeRqst($parent.row)" type="submit">Delete Row</button>
{{$parent.$index}}
