平時在應(yīng)用ajax完成一些操作后總會使用alert來給用戶返回一些提示信息。但是介于alert的樣式過于單調(diào)。所以有時候需要自己寫一個類似的提示框來稍微的美化一下。
那天從網(wǎng)上找了一個現(xiàn)成的提示框。不過那個提示框還是有一些缺陷的，在出現(xiàn)瀏覽器測滾輪情況下和在IE與FF之間的兼容問題。自己修改了一下現(xiàn)在能夠正常的在兩個瀏覽器上使用。
以下是代碼：
//提交完畢后彈出提示信息并自動關(guān)閉
function Alert(str) {
var msgw,msgh,bordercolor;
msgw=350;//提示窗口的寬度
msgh=80;//提示窗口的高度
titleheight=25 //提示窗口標(biāo)題高度
bordercolor="#336699";//提示窗口的邊框顏色
titlecolor="#99CCFF";//提示窗口的標(biāo)題顏色
var sWidth,sHeight;
//獲取當(dāng)前窗口尺寸
sWidth = document.body.offsetWidth;
sHeight = document.body.scrollHeight;
//背景div
var bgObj=document.createElement("div");
bgObj.setAttribute(‘id‘,‘a(chǎn)lertbgDiv‘);
bgObj.style.position="absolute";
bgObj.style.top="0";
bgObj.style.background="#E8E8E8";
bgObj.style.filter="progid:DXImageTransform.Microsoft.Alpha(style=3,opacity=25,finishOpacity=75";
bgObj.style.opacity="0.6";
bgObj.style.left="0";
bgObj.style.width = sWidth + "px";
bgObj.style.height = sHeight + "px";
bgObj.style.zIndex = "10000";
document.body.appendChild(bgObj);
//創(chuàng)建提示窗口的div
var msgObj = document.createElement("div")
msgObj.setAttribute("id","alertmsgDiv");
msgObj.setAttribute("align","center");
msgObj.style.background="white";
msgObj.style.border="1px solid " + bordercolor;
msgObj.style.position = "absolute";
msgObj.style.left = "50%";
msgObj.style.font="12px/1.6em Verdana, Geneva, Arial, Helvetica, sans-serif";
//窗口距離左側(cè)和頂端的距離
msgObj.style.marginLeft = "-225px";
//窗口被卷去的高+（屏幕可用工作區(qū)高/2）-150
msgObj.style.top = document.body.scrollTop+(window.screen.availHeight/2)-150 +"px";
msgObj.style.width = msgw + "px";
msgObj.style.height = msgh + "px";
msgObj.style.textAlign = "center";
msgObj.style.lineHeight ="25px";
msgObj.style.zIndex = "10001";
document.body.appendChild(msgObj);
//提示信息標(biāo)題
var title=document.createElement("h4");
title.setAttribute("id","alertmsgTitle");
title.setAttribute("align","left");
title.style.margin="0";
title.style.padding="3px";
title.style.background = bordercolor;
title.style.filter="progid:DXImageTransform.Microsoft.Alpha(startX=20, startY=20, finishX=100, finishY=100,style=1,opacity=75,finishOpacity=100);";
title.style.opacity="0.75";
title.style.border="1px solid " + bordercolor;
title.style.height="18px";
title.style.font="12px Verdana, Geneva, Arial, Helvetica, sans-serif";
title.style.color="white";
title.innerHTML="飛鴿Digg Alpha 0.1";
document.getElementById("alertmsgDiv").appendChild(title);
//提示信息
var txt = document.createElement("p");
txt.setAttribute("id","msgTxt");
txt.style.margin="16px 0";
txt.innerHTML = str;
document.getElementById("alertmsgDiv").appendChild(txt);
//1.5秒鐘后窗口自動關(guān)閉
window.setTimeout("closewin()",1500);
}
function closewin() {
document.body.removeChild(document.getElementById("alertbgDiv"));
document.getElementById("alertmsgDiv").removeChild(document.getElementById("alertmsgTitle"));
document.body.removeChild(document.getElementById("alertmsgDiv"));
}
