如何创建“请稍候，正在加载..."?动画使用jQuery?

I would like to place a "please wait, loading" spinning circle animation on my site. How should I accomplish this using jQuery? 解决方案 You could do this various different ways. It could be a subtle as a small status on the page saying "Loading...", or as loud as an entire element graying out the page while the new data is loading. The approach I'm taking below will show you how to accomplish both methods.The SetupLet's start by getting us a nice "loading" animation from http://ajaxload.infoI'll be usingLet's create an element that we can show/hide anytime we're making an ajax request:<div class="modal"><!-- Place at bottom of page --></div>The CSSNext let's give it some flair:/* Start by setting display:none to make this hidden. Then we position it in relation to the viewport window with position:fixed. Width, height, top and left speak for themselves. Background we set to 80% white with our animation centered, and no-repeating */.modal { display: none; position: fixed; z-index: 1000; top: 0; left: 0; height: 100%; width: 100%; background: rgba( 255, 255, 255, .8 ) url('http://i.stack.imgur.com/FhHRx.gif') 50% 50% no-repeat;}/* When the body has the loading class, we turn the scrollbar off with overflow:hidden */body.loading .modal { overflow: hidden;}/* Anytime the body has the loading class, our modal element will be visible */body.loading .modal { display: block;}And finally, the jQueryAlright, on to the jQuery. This next part is actually really simple:$body = $("body");$(document).on({ ajaxStart: function() { $body.addClass("loading"); }, ajaxStop: function() { $body.removeClass("loading"); }});That's it! We're attaching some events to the body element anytime the ajaxStart or ajaxStop events are fired. When an ajax event starts, we add the "loading" class to the body. and when events are done, we remove the "loading" class from the body.See it in action: http://jsfiddle.net/VpDUG/4952/ 这篇关于如何创建“请稍候，正在加载..."?动画使用jQuery?的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
