我每次点击按钮时都会尝试添加新的选择
html:
<div ng-repeat = "select in selects track by $index">
<ui-select ng-model="selects[$index]" theme="select2" ng-disabled="disabled" style="min-width: 300px;">
<ui-select-match placeholder="Select a person in the list or search his name/age...">{{$select.selected.name}}</ui-select-match>
<ui-select-choices repeat="person in people">
<div ng-bind-html="person.name | highlight: $select.search"></div>
</ui-select-choices>
</ui-select>
</div>
<button ng-click="addNewSelect()"> Add new select</button>
控制器:
$scope.selects = [{}];
$scope.addNewSelect = function() {
$scope.selects.push({});
}
对象数组保存在数组'choices'中,但占位符不在选择中,因为我最初使用空对象初始化ng-model。如何让占位符在这种情况下工作?

.selected
之后您遗漏了selects[$index]
。
如果没有这个,ui-select认为您选择了一个空对象(selects[$index]
)并且不会显示占位符。
<ui-select ng-model="selects[$index].selected" theme="select2" ng-disabled="disabled" style="min-width: 300px;">

您也不需要使用索引查找,只需使用select.selected
<ui-select ng-model="select.selected" theme="select2" ng-disabled="disabled" style="min-width: 300px;">

添加css display的最快方法:阻止占位符项。
.select2-chosen{
display: block !important;
}

在某些情况下,上述解决方案效果很好,而在某些情况下效果不佳。
<ui-select ng-model="selectedChannel"
on-select="$ctrl.channelSelected(selectedChannel)">
<ui-select-match placeholder="Select Channel Type">
{{selectedChannel.text}}
</ui-select-match>
<ui-select-choices ui-select-header-group-selectable="$ctrl.selectGroupHeader"
group-by="groupFindChannel"
repeat="channel in (r.channels | filter: $select.search) track by channel.id">
<div ng-bind-html="channel.text | highlight: $select.search"></div>
</ui-select-choices>
</ui-select>
^在这里让占位符显示出来...只需
$scope.selectedChannel = null;
希望有帮助...
