Навигация по меню не позволяет мне взаимодействовать с другими кнопками?

Question

• 1000 Навигация по меню функционирует должным образом, открывая и закрывая, а ссылки в меню работают должным образом.

Однако у меня были проблемы, потому что до того, как я добавил меню в панель поиска, работало и слайд-шоу изображений, которое заставляет меня думать, что навигация по меню вызывает проблему.

var curpage = 1;
var sliding = false;
var click = true;
var left = document.getElementById("left");
var right = document.getElementById("right");
var pagePrefix = "slide";
var pageShift = 500;
var transitionPrefix = "circle";
var svg = true;

function leftSlide() {
  if (click) {
    if (curpage == 1) curpage = 5;
    console.log("woek");
    sliding = true;
    curpage--;
    svg = true;
    click = false;
    
    for (k = 1; k <= 4; k++) {
      var a1 = document.getElementById(pagePrefix + k);
      a1.className += " tran";
    }
    
    setTimeout(() => {
      move();
    }, 200);
    
    setTimeout(() => {
      for (k = 1; k <= 4; k++) {
        var a1 = document.getElementById(pagePrefix + k);
        a1.classList.remove("tran");
      }
    }, 1400);
  }
}

function rightSlide() {

Answer 1

Проблема вызвана использованием атрибута visibility, лучший способ скрыть элемент - использовать display:none;, а для анимации я обычно использую атрибут opacity, различается между отображением: нет и видимостью: скрыто :

var curpage = 1;
var sliding = false;
var click = true;
var left = document.getElementById("left");
var right = document.getElementById("right");
var pagePrefix = "slide";
var pageShift = 500;
var transitionPrefix = "circle";
var svg = true;

function leftSlide() {
  if (click) {
    if (curpage == 1) curpage = 5;
    console.log("woek");
    sliding = true;
    curpage--;
    svg = true;
    click = false;
    
    for (k = 1; k <= 4; k++) {
      var a1 = document.getElementById(pagePrefix + k);
      a1.className += " tran";
    }
    
    setTimeout(() => {
      move();
    }, 200);
    
    setTimeout(() => {
      for (k = 1; k <= 4; k++) {
        var a1 = document.getElementById(pagePrefix + k);
        a1.classList.remove("tran");
      }
    }, 1400);
  }
}

function rightSlide() {
  if (click) {
    if (curpage == 4) 
      curpage = 0;
      
    console.log("woek");
    
    sliding = true;
    curpage++;
    svg = false;
    click = false;
    
    for (k = 1; k <= 4; k++) {
      var a1 = document.getElementById(pagePrefix + k);
      a1.className += " tran";
    }
    
    setTimeout(() => {
      move();
    }, 200);
    
    setTimeout(() => {
      for (k = 1; k <= 4; k++) {
        var a1 = document.getElementById(pagePrefix + k);
        a1.classList.remove("tran");
      }
    }, 1400);
  }
}

function move() {
  if (sliding) {
    sliding = false;
    
    if (svg) {
      for (j = 1; j <= 9; j++) {
        var c = document.getElementById(transitionPrefix + j);
        c.classList.remove("steap");
        c.setAttribute("class", transitionPrefix + j + " streak");
        console.log("streak");
      }
    } else {
      for (j = 10; j <= 18; j++) {
        var c = document.getElementById(transitionPrefix + j);
        c.classList.remove("steap");
        c.setAttribute("class", transitionPrefix + j + " streak");
        console.log("streak");
      }
    }
    
    setTimeout(() => {
      for (i = 1; i <= 4; i++) {
        if (i == curpage) {
          var a = document.getElementById(pagePrefix + i);
          a.className += " up1";
        } else {
          var b = document.getElementById(pagePrefix + i);
          b.classList.remove("up1");
        }
      }
      sliding = true;
    }, 600);
    
    setTimeout(() => {
      click = true;
    }, 1700);

    setTimeout(() => {
      if (svg) {
        for (j = 1; j <= 9; j++) {
          var c = document.getElementById(transitionPrefix + j);
          c.classList.remove("streak");
          c.setAttribute("class", transitionPrefix + j + " steap");
        }
      } else {
        for (j = 10; j <= 18; j++) {
          var c = document.getElementById(transitionPrefix + j);
          c.classList.remove("streak");
          c.setAttribute("class", transitionPrefix + j + " steap");
        }
        sliding = true;
      }
    }, 850);
    
    setTimeout(() => {
      click = true;
    }, 1700);
  }
}

left.onmousedown = () => {
  leftSlide();
};

right.onmousedown = () => {
  rightSlide();
};

document.onkeydown = e => {
  if (e.keyCode == 37) {
    leftSlide();
  } else if (e.keyCode == 39) {
    rightSlide();
  }
};

// setTimeout(() => {

// menu nav

  var body = document.body;
  var burgerMenu = document.getElementsByClassName('b-menu')[0];
  var burgerContain = document.getElementsByClassName('b-container')[0];
  var burgerNav = document.getElementsByClassName('b-nav')[0];

  burgerMenu.addEventListener('click', function toggleClasses() {
