javascript - 如何在角度选择的选择上获取按键事件的值

Question

我正在使用名为 localytics.directives 模块的角度选择选择，我想在这个选择输入中设置一个按键事件，我怎样才能得到这个值？谢谢！

       <select chosen
                  ng-change="vm.fixItem(matchedLevel,unresolved)"
                  disable-search="false"
                  ng-model="matchedLevel"
                  ng-options="matchedLevel as matchedLevel.Name for
                  matchedLevel in level.allLevelItems">
      </select>

在您选择的指令链接器函数中尝试此代码

$(".chosen-container").unbind('keyup').bind('keyup',function(e) {
                    //console.log('sfddf');
                    var searchStr = $('.chosen-container .search-field input').val();
                    console.log(searchStr);
                });
