I think by using javascript with DOM we can put alert's boxes .Uh, think?
I wasn't talking about alerts. Alerts also have nothing to do with DOM.
but how to erase that error message of JSF in XHTML pageI already answered that. If you just want plain code, you're here at the wrong place.
Better learn Javascript and HTML DOM. w3schools has nice tutorials about that.
