从ui-select框中进行选择后,所选选项不会粘贴(不可见)

Question

我为此创建了一个plunker:http://plnkr.co/edit/5nk4BnYoO52En7P6kPu9

选择选项,但是当您选择一个时,ui-select保留为空白.潜在的重要说明:我在指令(ui-bootstrap)中使用它.作为旁注 - 在plunker中没有包装指令,所以这不是罪魁祸首.

<ui-select search-enabled="true" ng-change="updateMedu()" style="width: 100%" ng-model="medications.chosenMedications.metadata.conceptGroup.conceptProperties">
    <ui-select-match placeholder="Please click to choose or start typing dosage value..">{{$item}}</ui-select-match>
    <ui-select-choices repeat="cp in medications.chosenMedications.metadata[key].conceptGroup[1].conceptProperties | filter: $select.search">
        {{cp.synonym}}
    </ui-select-choices>
</ui-select>

手动模拟数据集:

$scope.medications.chosenMedications.metadata = [
    {
        conceptGroup: [
            {
                conceptProperties: [
                   {synonym: "Item One"},
                   {synonym: "Item Two"},
                   {synonym: "Item Three"}
                ]
            },
            {
                conceptProperties: [
                    {synonym: "Item A"},
                    {synonym: "Item B"},
                    {synonym: "Item C"}
                ]
            }
         ]
     }
];

Answer 1

只需尝试以下代码:

<ui-select theme="select2" search-enabled="true" style="width: 100%" 
        ng-model="medications.chosenMedications.metadata.conceptGroup.conceptProperties">
    <ui-select-match placeholder="Click to select or start typing...">
        {{$select.selected.synonym}}
    </ui-select-match>
    <ui-select-choices repeat="cp in medications.chosenMedications.metadata[0].conceptGroup[1].conceptProperties | filter: $select.search">
            {{cp.synonym}}
    </ui-select-choices>
</ui-select>

你的问题是你尝试显示{{$item}}而不是{{$select.selected.synonym}}

希望,这将解决您的问题.
