复制代码 代码如下:var str="客服"; var objFT=new FloatT("FloatMenu1",str,942,137,125,200,80,10); objFT.FloatRun(); //js跟随滚动条滚动 浮动 //pObjName:html 元素ID //pText:html 元素内容 //其它自己看 function FloatT(pObjName,pText,pstmnLEFT,pstmnGAP1,pstmnGAP2,pstmnBASE,pstmnActivateSpeed,pstmnScrollSpeed) { var FloatMenu; var stmnLEFT = pstmnLEFT; var stmnGAP1 = pstmnGAP1; var stmnGAP2 = pstmnGAP2; var stmnBASE = pstmnBASE; var stmnActivateSpeed = pstmnActivateSpeed; var stmnScrollSpeed = pstmnScrollSpeed; this.FloatRun=function(pObjName) { var newDiv=document.createElement("div"); newDiv.id=pObjName; newDiv.innerHTML=pText; newDiv.style.position="absolute"; document.body.appendChild(newDiv); FloatMenu=document.getElementById(pObjName); FloatMenu.style.display==""; FloatMenu.style.top = document.documentElement.scrollTop + stmnBASE+"px"; FloatMenu.style.left = stmnLEFT+"px"; RefreshStaticMenu(); } RefreshStaticMenu=function() { var stmnStartPoint,stmnEndPoint,stmnRefreshTimer; stmnStartPoint = parseInt(FloatMenu.style.top, 10); stmnEndPoint = document.documentElement.scrollTop + stmnGAP2; if (stmnEndPoint < stmnGAP1) stmnEndPoint = stmnGAP1; if(stmnStartPoint != stmnEndPoint) { stmnScrollAmount = Math.ceil(Math.abs(stmnEndPoint - stmnStartPoint) / 15 ); FloatMenu.style.top = parseInt(FloatMenu.style.top, 10) + ((stmnEndPoint<stmnStartPoint) ? -stmnScrollAmount : stmnScrollAmount)+"px"; stmnRefreshTimer = stmnScrollSpeed; } else { stmnRefreshTimer = stmnActivateSpeed; } setTimeout("RefreshStaticMenu();", stmnRefreshTimer); } }

　　JavaScript 数组循环引起的思考

看代码，不说话： 复制代码 代码如下: var i=arr.length; while(i--) { //写点啥？ } 上面是Google array.js 程序中建议改进的代码。思考为什么i-- 到了 i为0时while循环结束了？下面的代码与它等价： 复制代码 代>>>详细阅读
