Descript: public msg js
2008-01-15 modified :can run in firefox.

1.confirmMsg(msg, fCallback, obj) 
==this can show cancel and confirm button
==param 1: msg
==param 2: when after you click confirm, continue to execute fCallback
==param 3: can use obj while fCallback is null and now only be used by <a> or <input> tag. == when <a> then click confirm button, can do eval(this.href)
when <input> then eval __dopostback
for example: confirmMsg("Do you sure?", function(){alert(1);Gooo();})
WSP.MessageBox.confirmMsg("Do you sure?", null, this);
2.WSP.MessageBox.errorMsg(msg, fCallback, obj)
3.WSP.MessageBox.alertMsg(msg, fCallback, obj)
4.WSP.MessageBox.tipMsg(msg, fCallback, obj)

For example:
WSP.MessageBox.confirmMsg("Do you sure?", function(){alert(1);})
WSP.MessageBox.errorMsg("error");
WSP.MessageBox.alertMsg("alert");
WSP.MessageBox.tipMsg("tip");
