jquery制作的弹窗提示窗口插件，包含多种模式。带有回执函数值的功能,需要的朋友可以参考下
代码如下:
<script type="text/javascript" src="js/jquery-1.7.1.min.js"></script>
<!--[if IE 6]>
<script type="text/javascript" src="js/iepngfix_tilebg.js"></script>
<![endif]-->
<script type="text/javascript">
function position(elem,l,t){
var isIE6 = !-[1,] && !window.XMLHttpRequest;
if(isIE6){
var style = elem.style,
dom = '(document.documentElement)',
left = l - document.documentElement.scrollLeft,
top = t - document.documentElement.scrollTop;
style.position = 'absolute';
style.removeExpression('left');
style.removeExpression('top');
style.setExpression('left', 'eval(' + dom + '.scrollLeft + ' + left + ') + "px"');
style.setExpression('top', 'eval(' + dom + '.scrollTop + ' + top + ') + "px"');
}else{
elem.style.position = 'fixed';
}
}
function scscms_alert(msg,sign,ok,can){
var c_=false;//是否已经关闭窗口，解决自动关闭与手动关闭冲突
sign=sign||"";

}else{

}
s+="</div><div id='alert_foot'></div></div>";
$("body").append(s);
$("#scs_alert").css("margin-top",-($("#scs_alert").height()/2)+"px"); //使其垂直居中
$("#scs_alert").focus(); //获取焦点，以防回车后无法触发函数
position(document.getElementById('mask_layer'),0,0);
position(document.getElementById('scs_alert'),$(window).width()/2,$(window).height()/2);
if (typeof can == "number"){
//定时关闭提示
setTimeout(function(){

}

if (code == 27){if(typeof(can)=="function")can()}
}
//绑定回车与ESC键
if (document.attachEvent)
document.attachEvent("onkeydown", modal_key);
else
document.addEventListener("keydown", modal_key, true);
}
