KeyUp (function (e) {if(e.which== -) {alert ("Enter Submit Form");    }            }); })

Second, Web page skin-changing function (need to combine jquery's cookie plugin, to record the user's choice)

/*The effect of skin change, do not know why, the effect of the cookie does not come out*/function Switchskin (MySkin) {$ ("#skin-css"). attr ("href","styles/skin/"+myskin+". CSS"); $("."+myskin). addclass ("selected"). Siblings (). Removeclass ("selected");$    //for the next time the user opens and refreshes, the last skin is still displayed, and a cookie is used to record the current selection .$.cookie ("Mycssskin", MySkin, {path:"/", Expires:Ten});} $ (function () {varMy_skin=$.cookie ("Mycssskin");    alert (My_skin); if(My_skin) {Switchskin (My_skin); }    $(". Skin Li"). Click (function () {My_skin=$( This). attr ("class");         Switchskin (My_skin); });});
