您好，我正在为多个自动完成实现 ui-select 角度指令。使用 angular 版本 1.2.18 它工作正常，但是当我使用 angular 1.5.5 时出现类似错误：无法在 ctrl.getplaceholder 处获取未定义或空引用的属性“长度”
我的 HTML 代码是：
<ui-select multiple tagging="tagTransform" tagging-tokens="SPACE|,|/" ng-model="demo.selectedPeople" style="width: 800px;">
<ui-select-match placeholder="Select person...">{{$item.name}}</ui-select-match>
<ui-select-choices repeat="person in people | propsFilter: {name: $select.search}">
<div ng-if="person.isTag" ng-bind-html="person.name + ' ' + $select.taggingLabel | highlight: $select.search"></div>
<div ng-if="!person.isTag" ng-bind-html="person.name| highlight: $select.search"></div>
</ui-select-choices>
</ui-select>
我的控制器代码是：
lampiApp.controller('DemoCtrl', function ($scope, $http) {
$scope.tagTransform = function (newTag) {
var item = {
name: newTag,
};
return item;
};
$scope.people=[];
var str = "January,February,March,April,May,June,July,August,September,October singh";
var splittedString = str.split(',');
var arr = [];
splittedString.forEach(function (v) {
arr.push({ name: v });
});
$scope.people = arr;
});
