当用户选择一个名称
时，我尝试将id作为参数传递给搜索功能<input type="text" ng-model="RegionName" placeholder="Region" ng-blur="search(item.id)" uib-typeahead="item as item.name for item in items | filter:$viewValue | limitTo:10" class="form-control" >
我的JSON数据：
json : {"id":"000","name":"value1"},{"id":"001","name":"value2"}
Angularjs代码：
$scope.search = function (code) {
alert(code);
}
我得到的代码未定义。
我的错误在哪里。请提出你的建议。

更改为ng-blur="search(item.id)，它会起作用。，因为您将数据绑定到另一个属性ng-blur="search(RegionName.id)。
此外，我发现RegionName存在typeahead问题，因此我建议使用use ng-blur。
