Question

我有五个选项卡，它们正常运行。当我刷新页面时，当前活动的选项卡将转换为默认状态。但我想将它设置为当前活动状态，即使我刷新后也是如此。请让我知道我哪里出错了

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;
        };
    });
})();

Answer 1

将标签索引存储在localstorage中，并在页面刷新时再次设置它。因为索引来自本地存储转换为数字的字符串。

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

这是jsFiddle

更新了Js

from psycopg2 import sql

cur.execute(
    sql.SQL("LISTEN {};")
        .format(sql.Identifier(queue_listen_name)))

使用Angularjs将当前选项卡设置为活动选项卡
