我对 jQuery 相当陌生，我正在制作一个结果页面，用户可以在其中在列表和网格视图之间切换。它似乎确实有效，但是当我有很多结果时，它似乎有问题。谁能明白为什么会这样？

任何帮助将非常感激。

JS

    $('.btn.grid').click(function() {
      if (!$(this).hasClass("active")) {
        $(this).addClass("active");
        $('.results-wrapper .grid_12').removeClass("grid_12").addClass("grid_3");
        $('.wrapper .results').addClass("grid-view-active");
        if ($(".btn.list").hasClass("active")) {
          $(".btn.list").removeClass("active");
          $('.wrapper .results').removeClass("list-view-active");
        }
      }
    });
    $('.btn.list').click(function() {
      if (!$(this).hasClass("active")) {
        $(this).addClass("active");
        $('.results-wrapper .grid_3').removeClass("grid_3").addClass("grid_12");
        $('.wrapper .results').addClass("list-view-active");
        if ($(".btn.grid").hasClass("active")) {
          $(".btn.grid").removeClass("active");
          $('.wrapper .results').removeClass("grid-view-active");
        }
      }
    });

var gridButton = $('.btn.grid');
var listButton = $('.btn.list');
var isGridActive = true;

gridButton.click(function() { 
  if(!isGridActive) {
    toggleFunction();
  }
});


listButton.click(function() { 
  if(isGridActive) {
    toggleFunction();
  }
});

var toggleFunction = function(){
  listButton.toggleClass("active");
  gridButton.toggleClass("active");

  if(isGridActive) {
    $('.results-wrapper .grid_3').removeClass("grid_3").addClass("grid_12");
  $('.wrapper .results').addClass("list-view-active").removeClass("grid-view-active");
  } else { 
    $('.results-wrapper .grid_12').removeClass("grid_12").addClass("grid_3");
        $('.wrapper .results').addClass("grid-view-active").removeClass("list-view-active");
  }
  isGridActive = !isGridActive;
};

如果有人可以使 if 语句更好，那就太好了。
