自己写了个ExtJS的MsgBox的小模版，以后遇到需要使用提示的地方就拿过来改改，免得每次都重新写。
/**MsgBox start**/
Ext.Msg.buttonText.yes = "是";
Ext.Msg.buttonText.no = "否";
Ext.Msg.buttonText.cancel = "退出";
Ext.Msg.buttonText.ok = "确定";
var errorTitle = "错误提示";
var infoTitle = "信息提示";
var questionTitle = "问确定提示";
var warningTitle = "警告提示";
Ext.Msg.show({
title: errorTitle, //errorTitle infoTitle questionTitle warningTitle
closable: false,
width: 300,
icon: Ext.MessageBox.ERROR, // ERROR INFO QUESTION WARNING
msg: "你确定要删除该用户吗?",
buttons: Ext.Msg.YESNO, // CANCEL OK OKCANCEL YESNO YESNOCANCEL
fn: function(btn) {
if(btn == "yes" || btn == "ok") {
alert(btn);
} else if(btn == "no" || btn == "cancel"){
alert(btn);
}
}
});
/**MsgBox end**/
