javascript - 使用 Angularjs 将当前选项卡设置为事件选项卡

Question

我有五个选项卡，它们工作正常。当我刷新页面时，当前事件的选项卡将转变为默认状态。但我想将其设置为当前事件状态，即使在刷新后也是如此。请告诉我哪里出错了

HTML 代码:

    <div class="container">
    <section ng-app="myApp" ng-controller="TabController as tab">
       <ul class="nav nav-pills">
            <li ng-class="{active:tab.isSet(1)}"><a href ng-click="tab.setTab(1)">Home</a></li>
            <li ng-class="{active:tab.isSet(2)}"><a href ng-click="tab.setTab(2)">Underwriting</a></li>
            <li ng-class="{active:tab.isSet(3)}"><a href ng-click="tab.setTab(3)">Operations</a></li>
        </ul>

        <div ng-show="tab.isSet(1)">
             <h4>Home</h4>
        </div>
        <div ng-show="tab.isSet(2)">
             <h4>Underwriting</h4>
        </div>
        <div ng-show="tab.isSet(3)">
             <h4>Operations</h4>
        </div>
    </section>
</div>

Js:

    (function () {
    var app = angular.module('myApp', []);

    app.controller('TabController', function () {
        this.tab = 1;  ---> Here I am failing to apply the logic.

        this.setTab = function (tabId) {
            this.tab = tabId;
        };

        this.isSet = function (tabId) {
            return this.tab === tabId;
        };
    });
})();

将选项卡索引存储在本地存储中，并在页面刷新时再次设置。由于索引以字符串形式从本地存储转换为数字。

this.tab = +localStorage.getItem('tabIndex') || 1;
this.setTab = function (tabId) {
  this.tab = tabId;
  localStorage.setItem('tabIndex', tabId);
};
