javascript - 在Angular JS中提交表单时如何获取输入字段的标签

我想要实现的是，当我提交表单时，它应该返回我在控制台中选择的选项的标签，但它返回的是选项的值。

预期结果：
 DXBA-天空

结果得到：
 迪拜

的HTML

<div class="suggestField">
    <input type='text' list='listid' placeholder="TO" ng-model="toCity" ng- change="suggestCity(toCity)">
    <datalist id='listid'>
          <option ng-repeat="item in fromSuggestData" label='{{item.PlaceId}}' value='{{item.PlaceName}}'>
    </datalist>
    <button ng-click="submitForm(toCity)">SUBMIT</button>
</div>

JS

$scope.fromSuggestData = {
    "PlaceId": "DXBA-sky",
    "PlaceName": "Dubai",
    "CountryId": "AE-sky",
    "RegionId": "",
    "CityId": "DXBA-sky",
    "CountryName": "United Arab Emirates"
}, {
    "PlaceId": "DUJ-sky",
    "PlaceName": "Dubois",
    "CountryId": "US-sky",
    "RegionId": "PA",
    "CityId": "DUJA-sky",
    "CountryName": "United States"
}
$scope.submitForm = function(toCity) {
    console.log(toCity);
}

最佳答案

这是使用ng-option的演示。

var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope) {
  $scope.fromSuggestData = [{
    "PlaceId": "DXBA-sky",
    "PlaceName": "Dubai",
    "CountryId": "AE-sky",
    "RegionId": "",
    "CityId": "DXBA-sky",
    "CountryName": "United Arab Emirates"
  }, {
    "PlaceId": "DUJ-sky",
    "PlaceName": "Dubois",
    "CountryId": "US-sky",
    "RegionId": "PA",
    "CityId": "DUJA-sky",
    "CountryName": "United States"
  }];
  $scope.submitForm = function(toCity) {
    console.log(toCity);
  }
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="myCtrl" class="suggestField">
  <select id="cityname" ng-model="toCity" ng-options="item as item.PlaceName for item in fromSuggestData">
    <option value="">Select</option>
  </select>
  <button ng-click="submitForm(toCity.PlaceId)">SUBMIT</button>
</div>
