复制代码代码如下:function initialize() {addcloud(); //为页面添加遮罩document.onreadystatechange = subSomething; //监听加载状态改变}function addcloud() {var bodyWidth = document.documentElement.clientWidth;var bodyHeight = Math.max(document.documentElement.clientHeight, document.body.scrollHeight);var bgObj = document.createElement("div" );bgObj.setAttribute( 'id', 'bgDiv' );bgObj.style.position = "absolute";bgObj.style.top = "0";bgObj.style.background = "#000000";bgObj.style.filter = "progid:DXImageTransform.Microsoft.Alpha(style=3,opacity=25,finishOpacity=75" ;bgObj.style.opacity = "0.5";bgObj.style.left = "0";bgObj.style.width = bodyWidth + "px";bgObj.style.height = bodyHeight + "px";bgObj.style.zIndex = "10000"; //设置它的zindex属性，让这个div在z轴最大，用户点击页面任何东西都不会有反应|document.body.appendChild(bgObj); //添加遮罩var loadingObj = document.createElement("div");loadingObj.setAttribute( 'id', 'loadingDiv' );loadingObj.style.position = "absolute";loadingObj.style.top = bodyHeight / 2 - 32 + "px";loadingObj.style.left = bodyWidth / 2 + "px";loadingObj.style.background = "url(../img/loading.gif)" ;loadingObj.style.width = "32px";loadingObj.style.height = "32px";loadingObj.style.zIndex = "10000";document.body.appendChild(loadingObj); //添加loading动画-}function removecloud() {$( "#loadingDiv").remove();$( "#bgDiv").remove();}function subSomething() {if (document.readyState == "complete" ) //当页面加载完毕移除页面遮罩，移除loading动画-{removecloud();}}
