如何使用 ng-repeat 和过滤器获取数据列表选择的选项 ids 值？

Question

我使用数据列表搜索我在输入字段中输入的值，filtered.i 需要将所选选项 ID 发送到控制器功能。

<input list="browsers" type="text" id="searchtextbox" class="form-control" placeholder="Search" ng-model="searchText">
<datalist id="browsers">
       <option ng-repeat="data in enroldata | filter: searchText" id="{{data.USERID}}" id="{{data.USERID}}" value="{{data.FIRSTNAME}} {{data.LASTNAME}}">{{data.FIRSTNAME}} {{data.LASTNAME}}</option>
 </datalist>
  <input type="button" class="btn btn-primary btn-flat" ng-click="enrol({{data.USERID}})" value="Send" />

在控制器中

 $scope.enrol = function (USERID) {
        debugger;
        var value = $scope.USERID;
        var val = $('#searchtextbox').val();
        var states = $('#browsers');
        var endVal = $(states).find('option[value="' + val + '"]');
        //depending on your logic, if endVal is empty it means the value wasn't found in the datalist, you can take some action here
        return endVal.text();


        var USERID1 = $scope.searchText;
        //var value = $('#searchText').val();
        //alert($('#browsers [value="' + value + '"]').data('value'));
        //var x = $('#searchtextbox').val();
        //var z = $('#browsers');
        //var val = $(z).find('option[value="' + x + '"]');
        //var endval = val.attr('id');
        //alert(endval);
        debugger;
        var dat = {
            "courseid": localStorage.getItem("courseid")
        , "USERID": USERID
        }
}

我需要按用户名搜索并通过函数或 ID 绑定传递 USERID.... 我试图通过 id 调用它并通过函数传递它的 return undefined

Answer 1

ng-repeat="data in enroldata | filter: searchText" 数据只能从 ng-repeat 内部访问我认为您可以简单地在单击 (ng-click="enrol()") 时调用 enrol() 并从 $scope.enrolData

获取控制器内部的数据
