Question

我已创建此animation，我想将其用作预加载器。我可以使用由html，css和js构建的动画，还是应该创建.gif或简单的css动画？如果我可以使用它，我该如何在我的网站上实现它？我已经看过一些教程，其中大多数人创建一个css动画并将该类调用到正文等等，我的问题是另一回事。

var bar = $('span');
var p = $('.noumero');

var width = bar.attr('style');
width = width.replace("width:", "");
width = width.substr(0, width.length-1);

var interval;
var start = 0; 
var end = parseInt(width);
var current = start;

var countUp = function() {
  current++;
 p.html(current);

 if (current === end) {
  clearInterval(interval);
 }
 };

 interval = setInterval(countUp, (2000 / (end + 1)));

Answer 1

对我来说，简单的方法是使用像FontAwesome中可以找到的微调器。但是如果你想将你的动画整合为预加载器，你需要调用另一个能够检查加载状态的函数，如果它正在改进，你可以调用08：

countup

在interval = setInterval(checkLoading, (2000 / (end + 1)));中，您可以使用简单的数学公式来准确了解您的进度：

checkLoading

Answer 2

您可以在display:none处将要显示的文档内容设置为css;使用$.holdReady()来保存.ready()个处理程序; .fadeToggle()在动画完成时淡出.meter元素，并在.fadeToggle()容器完成.meter后淡出文档内容

$.holdReady(true);

var bar = $('span');
var p = $('.noumero');

var width = bar.attr('style');
width = width.replace("width:", "");
width = width.substr(0, width.length - 1);

var interval;
var start = 0;
var end = parseInt(width);
var current = start;

var countUp = function() {
  current++;
  p.html(current);

  if (current === end) {
    clearInterval(interval);
    $(".meter").fadeToggle(500, function() {
      $.holdReady(false);
    })
  }
};

interval = setInterval(countUp, (2000 / (end + 1)));

$(document).ready(function() {
  $(".content").fadeToggle(5000)
})

div.meter {
  position: relative;
