EasyUI-加载完Html内容样式渲染完成后显示
等待页面的css样式加载完毕,Html内容加载完毕,样式生成后再进行展示,避免一开始加载内容后,逐渐渲染样式造成的不良视觉效果,增强用户体验。
新增base-loading.js文件,代码如下
//获取浏览器页面可见高度和宽度 var _PageHeight = document.documentElement.clientHeight, _PageWidth = document.documentElement.clientWidth; //计算loading框距离顶部和左部的距离(loading框的宽度为215px,高度为61px) var _LoadingTop = _PageHeight > 61 ? (_PageHeight - 61) / 2 : 0, _LoadingLeft = _PageWidth > 215 ? (_PageWidth - 215) / 2 : 0; //加载gif地址 var Loadimagerul="/Content/LoadJs/Image/loading.gif"; //在页面未加载完毕之前显示的loading Html自定义内容 var _LoadingHtml = '<div id="loadingDiv" style="position:absolute;left:0;width:100%;height:' + _PageHeight + 'px;top:0;background:#f3f8ff;opacity:1;filter:alpha(opacity=80);z-index:10000;"><div style="position: absolute; cursor1: wait; left: ' + _LoadingLeft + 'px; top:' + _LoadingTop + 'px; width:100px;; height: 57px; line-height: 57px; padding-left: 50px; padding-right: 5px; background: #fff url('+Loadimagerul+') no-repeat scroll 5px 12px; border: 2px solid #95B8E7; color: #696969; font-family:\'Microsoft YaHei\';">玩命加载中...</div></div>'; //呈现loading效果 document.write(_LoadingHtml); //监听加载状态改变 document.onreadystatechange = completeLoading; //加载状态为complete时移除loading效果 function completeLoading() { if (document.readyState == "complete") { var loadingMask = document.getElementById('loadingDiv'); loadingMask.parentNode.removeChild(loadingMask); } }
使用的时候,只需要在Head中引入就可以
@*//加载JS动画效果*@ <script src="~/Content/LoadJs/base-loading.js"></script>
