问如果状态函数不读取布尔值，则使用javascript

EN

var footerMenu = ['#about', '#help']
var slideSwitch = false

function slideDown(){
  footerMenu.forEach(function(list){
      $(list+' p').click(function(){
        $(list+' ul').slideToggle(300)
      })
    })
}

function slideClear(){
  for( let i = 0; i < footerMenu.length; i++){ 
    $(footerMenu[i]+' p').click(function(){
      var choice = footerMenu[i]
      footerMenu.splice(i, 1);
      footerMenu.forEach(function(list){ 
      $(list+' ul').slideUp(300)
      })
      footerMenu.splice(i, 0, choice);
    })
  }
}

function slideTotal(){
  if(slideSwitch = true){
    slideDown()
    slideClear()
  } 
}

$(document).ready(function() {
  checkWidth();
});
$(window).resize(function(){
  checkWidth();
});

function checkWidth(){
  $vWidth = $(window).width();

  if($vWidth <576){
       console.log("Width: Less than 576");
       slideSwitch = true
  }else{
       console.log("Width: More than 576");
      slideSwitch = false
  } 
}

slideTotal()
