我目前正在一个项目中,必须在其中构建一个包含百分比和定制svgs动画的加载屏幕.我已经遍及整个互联网,但是找不到我所需要的东西？我似乎什至无法获得一个简单的加载栏来工作！
我在下面列出了我目前拥有的东西.我一直在使用this walkthrough作为progressbar.js,因为它包含动画和百分比,但是任何指导将不胜感激！
(我的想法是让南瓜种子在栏杆加载时彼此旋转,然后连接在一起,一旦栏杆达到100％,南瓜就会弹出)

</body>解决方法:
我对progressbar.js并不熟悉,所以我真的不能为您提供太多帮助.
但是,使用CSS动画和过渡非常简单.结合了少量的Javascript.
为了演示设置越来越多的进度,我使用了一个简单的requestAnimationFrame()动画循环.
其余代码的工作方式在代码中.
var mysvg = document.querySelector("#animated svg");
//
// Call this function to set the amount of progress (0 .. 1)
//
function setProgress(progress)
{
// For debug purposes only: show the progress amount in a div so we can see the progress
document.getElementById("test").textContent = progress.toFixed(2);
// When progress is complete (1) start the pumpkin animation by adding a class to the SVG
if (progress >= 1) {
mysvg.classList.add("show-pumpkin");
} else {
mysvg.classList.remove("show-pumpkin");
}
}
// Set the initial state of the progress to 0
setProgress(0);
// Everything else below is just to simulate you calling setProgress() with an increasing value.
//
// A little animation that increments the progress amount for us.
// In a real situation you would be setting this yourself based on how much of your initialisation is complete etc.
//
var amt = 0;
function incrementPogress() {
amt += 0.005;
setProgress(amt);
if (amt <= 1)
window.requestAnimationFrame(incrementPogress);
}
// Start our progress incrementing simulation
window.requestAnimationFrame(incrementPogress);svg {
