我有2个多个列表框,如下所示
当我从左侧列表框中选择多个值并单击右箭头时,它会将这些值移动到右侧列表框中,这些值将从左侧列表框中删除。
HTML
<select multiple ng-model="selectedRoleValue">
<option ng-selected="selectrole" ng-repeat="role in roles | filter:searchRoleOne" value="{{role}}">{{role}}</option>
</select>
<img src="./images/arrow.svg" ng-click="addToRightPan()">
<select name="cars" multiple class="listMutiple top5" ng-model="removeRoleValue">
<option ng-selected="selectrrole" ng-repeat="role in newRoleValue | filter:searchRoleTwo" value="{{role}}">{{role}}</option>
</select>
coffeescript代码
$scope.roles = ["test role","test role1","test role2","test role3","test role4","test role5"]
$scope.addToRightPan = ()->
$scope.temprole = $scope.roles
for item in $scope.selectedRoleValue
$scope.newRoleValue.push item
t = $scope.temprole.filter (word) -> word isnt item
$scope.temprole = t
$scope.roles = $scope.temprole
return
addToRightPan()是将值从左侧列表框移动到右侧列表框的功能。
功能正常。但是,当我只选择左侧列表框中的值并移动到右侧列表框时,左侧列表框中会显示一个空行。但是,当我安慰价值时,我找不到任何空值或任何东西。
在inspect元素中,我发现了以下内容:
<option value="? string:Account Cordinator ?"></option>
我该如何删除它?或者是否可以明确刷新列表框?
答案 0 :(得分:1)
我得到了它的工作,
<select multiple ng-selected="selectrole" ng-model="selectedRoleValue" ng-options="role for role in roles | filter:searchRoleOne">
</select>
我将ng-repeat更改为ng-options
