javascript - 刷新页面时如何不显示所有框

问题描述

这是我正在构建的网站的一部分，我发现它可以解决这个问题。我想做一种过滤器，但我的问题是我不希望在刷新页面或加载页面时首先显示所有框。我不想显示所有框，而是显示它们类别中的框。

解决方案

$(function () {
'use strict';
  // Initial setup:
  // set the name of the starting category
  var startingCategory = "brand";
  // add the active class to the li item in the menu:
  $('#digital ul.digital-filter li[data-value="' + startingCategory + '"]').addClass('active');
  // hide everything apart from the startingCategory (using the :not() css selector):
  $('#digital .digital-items .item:not(.' + startingCategory + ')').hide();
  //
  $('#digital ul.digital-filter li').on('click', function () {
    // store the name of data-value
    var value = $(this).data("value");

    // add active to clicked li, remove from all others:
    $(this).addClass('active').siblings().removeClass('active');
    // Hide All boxes first
    $.when($('#digital .digital-items .item').fadeOut(0)).then(function () {
      // after all boxes are hidden show only the ones you want
      // uses $.when to check the animation has finished on all boxes
      $('#digital .digital-items .item' + '.' + value).show();
   });
  });
});

你可以看到它在JSFiddle上工作

另一种方法是您可以click()在其中一个菜单项上触发事件，但根据动画速度/延迟将在页面加载时显示所有框，然后动画“离开”，而这种方式应该迅速隐藏不需要的框。
