richiamare menu

**licio** · 06-10-2003, 16:53

Premetto che sono più che ignorante in javascript..........

Ho uno script abbastanza complesso (a mio parere ovviamente) negli heads che mi crea un menu a discesa.

Questo script viene richiamato nella pagina tramite

<body bgcolor="#ffffff" onload="initSwipeMenu()" onload="if(parent.frames[0]&&parent.frames['navig'].Go)parent.frames['navig'].Go();" scroll=no topmargin=0 marginheight=0 ;>

in questo modo il menu mi apre all'inizio della pagina. Se volessi farlo apparire in un altro posto (es in una cella) come faccio a richiamare lo script lì?

Grazie

Prova a cambiare il topmargin e marginheight...se non cambia nulla vuol dire che la posizione è settata all'interno della script

(postmetto ke neanke io sono 1 cima in js)

non funge........... e non mi pare sia settata nello script la posizione

Se posti il codice forse posso aiutarti

Ciao Licio

Dopo uno studio + o - approfondito

(ripeto ke di js ne conosco poco) credo di aver trovato la soluzione...
nello script, dove si trova "if(is.dom)" e "if(is.ie4)"
c'è la variabile styStr che contiene un position:absolute un width:"+(mAtt.width-wf) ed altro ancora...
prova ad aggiungere qui un pò di pixel x abbassarlo

P.S. Se non va bene ti consiglio di kiedere aiuto a Dennis (o ai moderatori) ke sono sicuramente + esperti di me in materia

**licio** · 09-10-2003, 13:34

uhm, no...............

secondo me le variabili da cambiare sono qui:

menuObj.prototype.timer = null;
menuObj.prototype.wipe = 0;
menuObj.prototype.offX = Function('oX = (is.ie || is.ns61 || is.moz) ?this.lyr.offsetLeft : parseInt(this.sty.left)+;return oX');
menuObj.prototype.offY = Function('oY = (is.ie || is.ns61 ||is.moz) ?this.lyr.offsetTop : parseInt(this.sty.top);return oY;');
menuObj.prototype.offW = Function('oW = (!is.ns4) ?this.lyr.offsetWidth : this.lyr.clip.width; return oW;')
menuObj.prototype.offH = Function('oH = (!is.ns4) ?this.lyr.offsetHeight : this.lyr.clip.height; return oH;')
menuObj.prototype.maxWipe = function() {
if(is.dom) return this.offH()+10;
if(is.ns4) return (sAtt.height*this.lyr.document.layers.length)+10;
}

ovviamente non so come :tongue:
