本人的解決方法：
重新寫方法替換alert與confirm，用模態窗口實現阻塞。
/**
*@param {String} msg 提示的信息
*/
function dhcsys_alert(msg){
var userAgent = window.navigator.userAgent;
if (userAgent.indexOf("MSIE 7.0")>0 || userAgent.indexOf("MSIE 8.0")>0) {
window.showModalDialog("alert.html",
{msg:msg},
"dialogWidth:300px;dialogHeight:120px;center:yes;toolbar=no;menubar:no;scrollbars:no;resizable:no;location:no;status:no;help:no;");
}else{
alert(msg);
}
}
/**
*@param {String} msg 提示的信息
*@param {String} YesOrNo 默認焦點在Yes上還是No上 可選值爲YES或NO.默認爲Yes
*/
function dhcsys_confirm(msg,YesOrNo){
var userAgent = window.navigator.userAgent;
if(userAgent.indexOf("MSIE 7.0")>0 || userAgent.indexOf("MSIE 8.0")>0) {
if(arguments.length==1){
YesOrNo = "YES";
}
return window.showModalDialog("confirm.html",
{msg:msg,YesOrNo:YesOrNo},
"dialogWidth:300px;dialogHeight:120px;center:yes;toolbar=no;menubar:no;resizable:no;location:no;status:no;help:no;");
}else{
return window.confirm(msg);
}
}下面是alert.html
