原理，定義自己定義的alert頁面(Message.jsp)和confirm頁面(confirm.jsp)，
之後通過showModalDialog，在javascript中顯示和alert()和confirm()相同的效果。

調用alert，使用自定義的showMessage()
function showMessage(title,info,type){
var Args = new Array(title,info,type);
var locationURL = DynamicHtmlGetApplicationUrlRoot()+"common/Message.jsp";
window.showModalDialog(locationURL,Args,"dialogWidth=420px;dialogHeight=190px;resizable:no;scroll:no;status:no");
}
調用confirm，使用自定義的showConfirm()
function showConfirm(strTitle,strMessage)
{
var locationURL = "/common/confirm.jsp";
var args = new Array();
args[args.length] = strTitle;
args[args.length] = strMessage;
args[args.length] = 1;
var result = showModalDialog(locationURL,args,"dialogWidth=425px;dialogHeight=190px;resizable:no;scroll:no;status:no");
return result;
}
參加jsp中實例
showMessage("信息提示","密碼不能爲空！","info");
if (showConfirm("工作流模塊","提交任務號爲：" + workflowid + " 的任務嗎？")){}
