首先，您需要遍历每个li，然后查找a标记的html。在数组中找到该单词。然后显示/隐藏它。

var brandmenu = $("#brandmenu");
    var myarr = ["Anvil", "Bulwark", "CornerStone", "District", "District Made", "Fruit of the Loom", "Gildan", "Hanes", "Jerzees", "Port & Company", "Port Authority", "Precious Cargo", "Red House", "Red Kap", "Russell Outdoors", "Sport-Tek"];

    $('.navList > li').each(function(index,val){
        var catName = $(this).find('a').html();
        var arraycontainsturtles = (myarr.indexOf(catName) > -1);
         if(arraycontainsturtles == true) {
            $(this).show();
          } else {
           $(this).hide();
         }
    });
