所以我想在angularJS中创建一个下拉选择菜单。我可以使用ng-repeat列出内容:
<table ng-table="tableParams" class="table">
<tr ng-repeat="food in foods">
<td data-title="'Name'">{{food.name}}</td>
</tr>
</table>
显示食物清单。我想把它变成一个选择。 但无论我尝试什么,它似乎都没有显示出来。 这是我到目前为止所做的工作:
<select id="food_select"class="form-control"
ng-model="food"
ng-options="item as item.name for item in food track by item.id">
<option value="">(Pick food)</option>
</select>
以下是我获取数据的方式:
function getFoodList() {
FoodService.getFoods().then(function (_data) {
$scope.foods= _data.foods;
console.log("foodlist"+JSON.stringify( $scope.foods));
});
}
这是一个json示例: “ID”: “540894f9b2a136082606e5f0”, “created_at”: “2014-09-04T16:36:09 + 0000”, “的updated_at”: “2014-09-04T16:36:09 + 0000”, “名”:“香蕉“
