jQuery函数只触发一次，

Question

我希望有两种搜索框样式，一种高于1000px，一种低于10​​00px。我通过CSS中的媒体查询使其可用，然后我将函数点击我的元素，但它只触发一次，然后我需要刷新页面才能再次执行。我是所有这一切的新手，我已经为这个问题寻找解决方案八小时了。我认为问题是由搜索表单引起的 - 当您单击搜索触发器时处于活动状态。但是，当我在1000px宽的范围内浏览时，我不知道如何禁用此功能。

我正在使用已创建主题的WordPress，名为Yuuta。

$(document).on('click', '.search-trigger', function() {
  $('.search-overlay').addClass('show');
  if ($('.site-header .search-form').hasClass('search-form--active')) {
    /* hide search field */
    $('.site-header .search-form').removeClass('search-form--active');
  } else {
    /* show search field */
    $('.site-header .search-form').addClass('search-form--active');
    /* focus search field */
    $('.site-header .search-field').focus();
  }
  /* show/hide search form via search icon */
  if ($('.site-header .search-trigger').hasClass('search-form--active')) {
    /* hide search field */
    $('.site-header .search-trigger').removeClass('search-form--active');
  } else {
    /* show search field */
    $('.site-header .search-trigger').addClass('search-form--active');
  }
});
