ui-select 列表中显示的重复项，当动态更新新值并更改 ui-select 中的 selected 值时，多个 (angular js)

Question

无法更新新值并动态更改 ui-select 中的 selected 值更新值在列表中重复

我添加了让员工更新模型和更新员工以添加新数据和预先select该值。

我所做的是

创建了一个添加模型按钮，它将填充 uiselect.
创建了一个更新模型按钮以添加新值并将其更改为 selected

单击添加模型时，它会列为 item1、item2 和 item3
单击更新模型时，它会添加一个新项目 "item4" 并将其设为 selected

问题是 item4 正在 selected 但它也显示在 selection

的列表中

 <ui-select style="width: 800px;" ng-disabled="disabled" theme="select2" ng-model="vm.employees.selected" multiple="">
  <ui-select-match placeholder="Select employee...">{{$item.name}} <{{$item.city}}></ui-select-match>
  <ui-select-choices refresh-delay="0" refresh="vm.getdata($select.search)" repeat="employee.id as employee in vm.employees | propsFilter: {name: $select.search}  ">
    <div ng-bind-html="employee.name | highlight: $select.search"></div>
    <small>
    name: {{employee.name}}

  </ui-select-choices>
</ui-select> 

app.controller('DemoCtrl', function($http) {
var vm = this;
vm.name = 'World';

function getemployee() {
    var employees = [];
    $http.get('employees.json').success(function(data) {

        vm.employees = data;
    });
}

vm.updateemployee = function() {
    console.log(vm.employees);

    vm.selvalues = vm.employees.selected;
    vm.employees.selected = undefined;
    vm.employees.push({
        id: 9,
        name: "test",
        city: "chennai",
        state: "TN"
    });
    vm.selvalues.push(9);
    vm.employees.selected = vm.selvalues;
    console.log(vm.employees);
    console.log(vm.employees.selected);
}

vm.getdata = function(query) {
    console.log(vm.employees);

    console.log(vm.employees.selected);

}

vm.employees = {};
vm.selvalues = [];
vm.employees.selected = [];
vm.employees = [];
vm.getemployee = getemployee;});

Answer 1

    vm.selvalues= vm.employees.selected;
 vm.employees.selected=undefined;
 vm.employees=vm.employees.concat({id:9,name:"test",city:"chennai",state:"TN"});    
 vm.employees.selected = vm.selvalues.concat(9);

将 push 更改为 concat 对我有用。 感谢所有试图帮助我的人
