js提示框

js中alert、confirm这种提示框由于局限性,有时不能够实现我们想要的效果,下面使用js写的提示框,可以写入代码并加以修改更加灵活。

<script type=”text/javascript” language=”javascript”>
function sAlert(strTitle,strContent){
var msgw,msgh,bordercolor;
msgw=400;//提示窗口的宽度
msgh=100;//提示窗口的高度
titleheight=25 //提示窗口标题高度
bordercolor=”#336699″;//提示窗口的边框颜色
titlecolor=”#99CCFF”;//提示窗口的标题颜色
var sWidth,sHeight;
sWidth=document.body.offsetWidth;
sHeight=screen.height;
var bgObj=document.createElement(“div”);
bgObj.setAttribute(‘id’,’bgDiv’);
bgObj.style.position=”absolute”;
bgObj.style.top=”0″;
bgObj.style.background=”#777″;
bgObj.style.filter=”progid:DXImageTransform.Microsoft.Alpha(class=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);
var msgObj=document.createElement(“div”)
msgObj.setAttribute(“id”,”msgDiv”);
msgObj.setAttribute(“align”,”center”);
msgObj.style.background=”white”;
msgObj.style.border=”1px solid ” + bordercolor;
msgObj.style.position = “absolute”;
msgObj.style.left = “50%”;
msgObj.style.top = “50%”;
msgObj.style.font=”12px/1.6em Verdana, Geneva, Arial, Helvetica, sans-serif”;
msgObj.style.marginLeft = “-225px” ;
msgObj.style.marginTop = -75+document.documentElement.scrollTop+”px”;
msgObj.style.width = msgw + “px”;
msgObj.style.height =msgh + “px”;
msgObj.style.textAlign = “center”;
msgObj.style.lineHeight =”25px”;
msgObj.style.zIndex = “10001”;
var title=document.createElement(“h4”);
title.setAttribute(“id”,”msgTitle”);
title.setAttribute(“align”,”right”);
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,class=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.style.cursor=”pointer”;
title.title = “点击关闭”;
title.innerHTML=”<table border=’0′ width=’100%’><tr><td align=’left’><b>”+ strTitle +”</b></td><td>关闭</td></tr></table></div>”;
title.onclick=function(){
document.body.removeChild(bgObj);
document.getElementById(“msgDiv”).removeChild(title);
document.body.removeChild(msgObj);
}
document.body.appendChild(msgObj);
document.getElementById(“msgDiv”).appendChild(title);
var txt=document.createElement(“p”);
txt.style.margin=”1em 0″
txt.setAttribute(“id”,”msgTxt”);
txt.innerHTML=strContent;
document.getElementById(“msgDiv”).appendChild(txt);
}
</script>
<input name=”txtMACAddr” type=”button” value=”anniu” onclick=’sAlert(“”,”aabbcc”)’/>
