javascript - 如何根据 URL 在 jquery 中使选项卡处于事件状态

Question

这里我使用选项卡，没关系，我想进行一些额外的更改，在我的页脚页面中我有 4 个链接，如果我单击该链接意味着 URL 应该像这样 ouroffice.php?cityname= chennai，现在我想要做的意味着基于城市名称，我想让选项卡处于事件状态我尝试过，但我无法使选项卡处于事件状态，怎么办？

//var cityname = '<?php echo $_GET['cityname']?>';
var cityname = "hydrabad";
if (cityname == "chennai") {
  $("#nv_li").tabs({
    active: 1
  });
} else if (cityname == "hydrabad") {
  $("#nv_li").tabs({
    active: 2
  });
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="row" style="padding-top: 30px;">
  <ul class="nav nav-tabs" id="nv_li">
    <li class="active" id="link"><a data-toggle="tab" href="#beng">BENGALURU</a>

只需使用 window.location.search 并运行函数(在文档准备好时)将事件类设置为适当的 li 元素，如下所示:

// Search parameter extractor
function getSearchParam(searchKey) {
  var params = window.location.search.replace('?', '').split('&');
  var searchParam = null;
  var keyValue;

  for (var i = 0, len = params.length; i < len; i++) {
    keyValue = params[i].split('=');

    if (keyValue[0] === searchKey) {
        searchParam = keyValue[1];
        break;
    }
  }

  return searchParam;
}

// Function to set active city class
function setActiveCity(cityName) {
    var link = document.querySelector('a[data-toggle="tab"][href="#' + cityName + '"]');
    var content = document.getElementById(cityName);


  if (link) {
    link.parentNode.classList.add('active');
  }

  if (content) {
    content.classList.add('in', 'active');
  }
}

var city = getSearchParam('cityname');

if (city) {
  setActiveCity(city);
}
