ciao a tutti, ho creato un menù a tendina partendo da uno script di html.it
ecco il codice che ne è venuto fuori
codice:
ho riscontrato delle incompatibilità con google chrome e internet explorer:codice:<html xmlns="http://www.w3.org/1999/xhtml" lang="it"> <head> <style type="text/css"> #dropmenudiv{ position:absolute; border-bottom-width: 0; font:normal 12px Verdana; z-index:100; } #dropmenudiv a{ width: 100%; display: block; text-decoration: none; } #dropmenudiv a:hover{ /*hover background color*/ } </style> <script type="text/javascript"> //Contents for menu 1 var menu1=new Array() menu1[0]='[img]/menu/news.png[/img]' menu1[1]='[img]/menu/gallery.png[/img]' menu1[2]='[img]/menu/video.png[/img]' menu1[3]='[img]/menu/attivita.png[/img]' //Contents for menu 2 var menu2=new Array() menu2[0]='[img]/menu/news.png[/img]' menu2[1]='[img]/menu/gallery.png[/img]' menu2[2]='[img]/menu/video.png[/img]' menu2[3]='[img]/menu/attivita.png[/img]' var menuwidth='188px' //default menu width var menubgcolor='white' //menu bgcolor var disappeardelay=50 //menu disappear speed onMouseout (in miliseconds) var hidemenu_onclick="yes" //hide menu when user clicks within menu? /////No further editting needed var ie4=document.all var ns6=document.getElementById&&!document.all if (ie4||ns6) document.write('<div id="dropmenudiv" style="visibility:hidden;width:'+menuwidth+';background-color:'+menubgcolor+'" onMouseover="clearhidemenu()" onMouseout="dynamichide(event)"></div>') function getposOffset(what, offsettype){ var totaloffset=(offsettype=="left")? what.offsetLeft : what.offsetTop; var parentEl=what.offsetParent; while (parentEl!=null){ totaloffset=(offsettype=="left")? totaloffset+parentEl.offsetLeft : totaloffset+parentEl.offsetTop; parentEl=parentEl.offsetParent; } return totaloffset; } function showhide(obj, e, visible, hidden, menuwidth){ if (ie4||ns6) dropmenuobj.style.left=dropmenuobj.style.top=-500 if (menuwidth!=""){ dropmenuobj.widthobj=dropmenuobj.style dropmenuobj.widthobj.width=menuwidth } if (e.type=="click" && obj.visibility==hidden || e.type=="mouseover") obj.visibility=visible else if (e.type=="click") obj.visibility=hidden } function iecompattest(){ return (document.compatMode && document.compatMode!="BackCompat")? document.documentElement : document.body } function clearbrowseredge(obj, whichedge){ var edgeoffset=0 if (whichedge=="rightedge"){ var windowedge=ie4 && !window.opera? iecompattest().scrollLeft+iecompattest().clientWidth-15 : window.pageXOffset+window.innerWidth-15 dropmenuobj.contentmeasure=dropmenuobj.offsetWidth if (windowedge-dropmenuobj.x < dropmenuobj.contentmeasure) edgeoffset=dropmenuobj.contentmeasure-obj.offsetWidth } else{ var topedge=ie4 && !window.opera? iecompattest().scrollTop : window.pageYOffset var windowedge=ie4 && !window.opera? iecompattest().scrollTop+iecompattest().clientHeight-15 : window.pageYOffset+window.innerHeight-18 dropmenuobj.contentmeasure=dropmenuobj.offsetHeight if (windowedge-dropmenuobj.y < dropmenuobj.contentmeasure){ //move up? edgeoffset=dropmenuobj.contentmeasure+obj.offsetHeight if ((dropmenuobj.y-topedge)<dropmenuobj.contentmeasure) //up no good either? edgeoffset=dropmenuobj.y+obj.offsetHeight-topedge } } return edgeoffset } function populatemenu(what){ if (ie4||ns6) dropmenuobj.innerHTML=what.join("") } function dropdownmenu(obj, e, menucontents, menuwidth){ if (window.event) event.cancelBubble=true else if (e.stopPropagation) e.stopPropagation() clearhidemenu() dropmenuobj=document.getElementById? document.getElementById("dropmenudiv") : dropmenudiv populatemenu(menucontents) if (ie4||ns6){ showhide(dropmenuobj.style, e, "visible", "hidden", menuwidth) dropmenuobj.x=getposOffset(obj, "left") dropmenuobj.y=getposOffset(obj, "top") dropmenuobj.style.left=dropmenuobj.x-clearbrowseredge(obj, "rightedge")+"px" dropmenuobj.style.top=dropmenuobj.y-clearbrowseredge(obj, "bottomedge")+obj.offsetHeight+"px" } return clickreturnvalue() } function clickreturnvalue(){ if (ie4||ns6) return false else return true } function contains_ns6(a, b) { while (b.parentNode) if ((b = b.parentNode) == a) return true; return false; } function dynamichide(e){ if (ie4&&!dropmenuobj.contains(e.toElement)) delayhidemenu() else if (ns6&&e.currentTarget!= e.relatedTarget&& !contains_ns6(e.currentTarget, e.relatedTarget)) delayhidemenu() } function hidemenu(e){ if (typeof dropmenuobj!="undefined"){ if (ie4||ns6) dropmenuobj.style.visibility="hidden" } } function delayhidemenu(){ if (ie4||ns6) delayhide=setTimeout("hidemenu()",disappeardelay) } function clearhidemenu(){ if (typeof delayhide!="undefined") clearTimeout(delayhide) } if (hidemenu_onclick=="yes") document.onclick=hidemenu </script> </head> <body > <div align="center" style="line-height: 0px;"> <table cellpadding="0px" cellspacing="0px"> <tr><td>[img]/menu/roma.png[/img] </td></tr> <tr><td>[img]/menu/milano.png[/img] </td></tr> </table> </div> </body> </html>
con chrome le voci principali ( quelle con sfondo rosso) si vedono giuste ovverro attaccate una sotto l'altra, quando però apro 1 dei 2 menu le sottovoci partono a metà della voce principale
con internet explorer il problema è inverso, le sottovoci si aprono correttamente però tra le voci principali vi è uno spazio vuoto che non ci dovrebbe essere.
mi sarebbe di grande aiuto anche se riusciste ad aiutarmi con 1 dei 2 problemi
qui potete vedere il menù in azione http://clubfaro.it/menu/
grazie a tutti
